Introduction
This classification guide is developed as a periodically growing resource to arm
operators with fraud type information and offer them a best practice for a common
fraud cases classification model. It is structured to support Fraud Operations
activities associated with the TM Forum Business Frameworx model. This guide
is intended to capture multi-technology fraud types, allowing carriers to access
known fraud information for all technologies in Telecommunications from one
resource. Questions, comments, and additional recommendations for fraud
information to be added to this document should be forwarded to the Fraud Team
Leader via the TM Forum website (Business Assurance Program >> Fraud
Team),
Information contained within this guide is to be used for general and introductory
purposes of understanding and identifying prevalent fraud types within the
industry today. Certain types within this guide may also identify further, more
detailed, reference information that the TM Forum recommends should be
examined to better understand that specific fraud type.
Fraud Management Classification Guide

Telecom Fraud Classification Model
Due to the constantly changing nature of Fraud, it is vital to accurately
characterize and measure fraudulent events to help understand how Fraud is
evolving and how effective the Fraud Management process is in tackling it.
Therefore, it is clear there is a need to correctly classify and record each
occurrence. However, the problem lies in the complexity of Fraud events. Usually
an event includes more than one Fraud type. Also, to ensure an effective and
efficient Fraud Management process, it is important to understand the context in
which Fraud is committed to take the right corrective and preventive measures.
Another aspect of Fraud Management is the importance of information
interchange and benchmarking, particularly in sharing Fraud Occurrences and
mitigation practices with other operators and industry organizations. By providing
this global response to Fraud, a fraudster’s financial gains can be minimized
when trying to replicate Fraud with other operators. This enables operators to
take corrective and preventive measures at an industry level. However, to ensure
efficient communication, it is important that there is a common and effective way
of classifying the Fraud events. This way, it will be possible to avoid ambiguous
situations, lack of information and, worst of all, double counting.
To better illustrate the current situation, it is common to see statistics of Telecom
Fraud where both Subscription Fraud and IRSF are in the TOP 5 reported fraud
types, either in quantity or value. The question that arises immediately is how
much of this subscription fraud is made to commit IRSF? And consequently, are
these statistics reliable? Are we not facing double counting of Fraud? Financial
impact is rarely directly related with subscription fraud. It can be related with
usage without intention to pay, equipment theft, misappropriation and many other
Frauds. However, in order to take the right actions and preventive measures, it is
essential to know that subscription fraud is one of the top ways of accessing
services or goods.

The Model
From the previous example, it is obvious that is not possible to classify Fraud in a
one-dimensional way. It is clear that we should at least keep track of the enabler
technique (how the Fraudster gets access to the services or goods), and the main
fraud types from which fraudsters benefit. Social engineering, Hacking, and
Malware are other typical examples of enabler techniques used to perpetrate
Fraud.
These two dimensions form the basis of the classification model proposed in this
document, but we still need to ensure that the model can capture the context in
which the Fraud was committed. Therefore, we need a set of attributes to
describe this context, namely the ones needed to classify the operator who
suffered Fraud, the impact of the Fraud, etc.
Looking at the two main dimensions in more detail, Enabler Technique and Fraud
Type, and having in mind the need of capturing the information to properly give
the context in which the Fraud was committed, it is easy to demonstrate that a set
of attributes associated with these dimensions are also needed. Let’s take as an
example IRSF or Call Resell; it is obvious that a proper classification model
should be able to collect auxiliary information like the country where the PRS
numbers are located or to where calls are being resold.
Finally, for the purpose of ensuring the best practice of recording and sharing the
proper mitigation strategies, together with the classification model, the proposed
information system should include a section where the relevant mitigation
strategy for the classified fraud is described.
Figure 1 summarizes the proposed Classification Model. This is a first version
proposal that ideally will be used as a basis for a broader discussion and tested
by a larger base of CSPs. Suggestions for improving this model should be sent
via the forum. If appropriate, these suggestions will be included in the document’s
next release. Some cases may not be straightforward to classify and questions
may arise, but the conclusions obtained by statistically analyzing separately
enablers from Fraud Types in real cases covered during the short testing period
are extremely interesting. It is also clear that further tests are needed to
consolidate and enrich the model.

Classification dimensions and attributes
Classification Section: General Data
This sections goal is to collect the relevant information about the Fraud Event, namely
the operator who suffered Fraud, and if possible to associate the fraud event to a specific
customer account, information related with the customer, the acquisition channel,
payment type and method. We should also register data here about the Fraud event’s
impact.

Classification Section: Fraud Enablers
This sections goal lists examples of Fraud enablers and Fraud enabler dimension
attributes. Fraud enabler is the method or technique of getting access to the goods or
service and perpetrating the Fraud. A Fraud Enabler can be an illegal action by itself. It is
possible to have one or a combination of a set of Fraud enablers for a specific Fraud
type. For example, for Fraud Type IRSF, the Fraud Enablers can be Fraud Subscription,
PBX Hacking, etc. Also One Fraud Enabler can be applied for more than one Type of
Fraud. For example Fraud Enabler Subscription Fraud can be a technique for IRSF, SIM
Box, Reselling Calls, Equipment, etc.

Classification Model: Future Work
As Fraud is a constantly changing threat, it is essential that the Classification Model is revised
periodically to ensure that is fulfills its goals. It is important that a common Classification Model is
widely adopted to ensure comparability of statistics and benchmarks, but also to ensure that all
relevant information is collected in a common format for distribution, and to maximize the benefits
of information sharing between CSPs.
Despite the fact that the model has been tested with hundreds of cases, this is the initial version
and needs to be used and improved (as mentioned at the beginning of this chapter), either by
using a better naming convention or enriching or correcting any of the existing information.
Therefore, it is important for all users of this model to give suggestions through the TMF Fraud
Team forum for them to be incorporated in future versions of the document.
Based on the suggestions kindly made by Herbert Galiano, Ericsson, in the next revisions the
following points, transcribed from the feedback received, should be discussed and addressed after
validation:
1. To revise naming conventions between Fraud Classification Model section and the
Telecom Frauds description to ensure coherence throughout the document.
2. “In the Telecom Frauds description, there are some concepts that Telecom Fraud
Community are not familiar, or are not part of day by day activities. For example.
Page 20. Misappropriation of Assets - Lapping, False Invoice, Long Firm, Inventory
Fraud, also pages 20 to 24 related to Financial Frauds. What we observed is today in
the market neither consultants, vendors and CSP teams addressed solutions for
those types of fraud. (Maybe this belongs to other areas in CSPs like Auditors,
Corporate Security area or Chief Risk Officer). I Suggested that this forum contribute
and focus only and exclusive in the traditional and new Fraud Types for the Telecom
industry.”
3. On page 9 for the Fraud Classification Model: “Suggest to include the Action or
Response as key process of the Fraud Management in Fraud Mitigation box. For
example: Automatically. Manual, Semi-Automatic; Actions: Block call origination,
block collect calls, disconnect, divert to Call center, etc. are some actions that fraud
analyst should be taken immediately after detection to avoid more losses.
4. On Page 9 for the Fraud Classification Model: “Suggest include the 1st Fraud Alarm
for detection. For example: FMS, RA System, e-mail HUR, external denounce, etc.
This will be very useful for fraud managers to have statistics which systems /tools
have a good performance.
5. On page 9 for the Fraud Classification Model: As we have Quantitative and
Qualitative impact we need now the "time". Suggest to include the TimeframeCycle of
the Fraud, since origination to the detection and action taken. For example, 5 days
duration, 12 hours, etc.
6. On page 12 for the Fraud Classification box we have the Enabler and Fraud Type,
What I suggest is to include a new variable in this model, the “Fraud Technical
Method“ as the specific technique or method that fraudsters are using to perpetrate
the fraud avoiding detection. For example. An international fraud criminal gang is
using intelligent SIM boxes to perpetrate Fraud Bypass avoiding detection by simple
FMS rules. Specifically they are using special features that simulate a human
behavior for a set of SIMs inserted in the SIM BOX.
7. Example :
Fraud Enabler: Tariff Rates/Pricing Plans Abuse
Fraud Technical Method: Human behavior SIM BOX features
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 16 of 66
Fraud Type: Interconnect Bypass / SIM Box
8. The Fraud Classification Model on page 9 is a good framework to fill by Fraud
Operations as describe specific type of fraud that they detected, however I´m not
sure that it is very clear for people that will use this document as first time, so I
suggest to include 3 examples with real cases (fiction companies)
9. I did not find some other types of fraud enablers/ types that are very common in fixed
and TV operators like Clip on Fraud, Pay phone Fraud, Bandwidth selling, False
Answer Supervision, Signal Piracy, etc. Also for Payments using fraudulent credit
cards.

Telecom Fraud Definitions
1. Fraud Identifier: Subscription and/or Identity Theft
Definition
Subscriber fraud occurs when a fraudulent individual/s obtain customer information and
uses it for securing service with an intent to avoid payment.
Description
Subscriber fraud involves the fraudulent individual obtaining the customer information
required for signing up for telecommunication service with authorization. The usage of the
service creates a payment obligation for the customer. It is common for fraudulent
individuals to constantly move to avoid being detected. If the fraudulent individual was
able to provide the identification credentials required for creating a false alias when
opening the service account, it puts the onus on the customers to prove that the service
was not used by them.
Subscriber fraud may be conducted in two ways:
- Fraudulent individual creating the account and using the service for their purpose
- An internal employee of the service provider is involved in the fraud
This fraud type is among the most common frauds due to the low technical knowledge
required to perform the fraud.
2. Fraud Identifier: Misappropriation of Assets - Theft
Definition
This type of fraud when individual/s theft of service provider/ company assets for personal
benefit. The company assets may include cash or non-cash assets (materials, trade
secrets, intellectual property).
Description
Misappropriation of assets in the form of theft usually involves internal resources, but may
also be committed by external supplier, customers or other entities involved in the
industry. Theft may occur before the assets are recorded in the company’s financial
records (skimming), while the asset is held by the company (misuse of larceny) or during
the purchase of the asset.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 21 of 66
3. Fraud Identifier: Misappropriation of Assets - Embezzlement
Definition
This type of fraud occurs when fraudulent individuals who have been entrusted with the
assets appropriates the asset through dishonest methods.
Description
Embezzlement involves the trusted individual/s converting the assets for their personal
benefit. It usually starts with a small proportion of the assets to minimize the risk of
detection and can continue for a long period of time (years or decades) without detection.
Hence it usually involves systematic and methodical activities that is intended to conceal
the fraud. Embezzlement is distinguished from theft from the fact that the fraudulent
individual involved is responsible for the asset (while in the case of theft the person is not
responsible for the asset). Embezzlement may also involve falsification of records done
for the purpose of concealing the activity.
4. Fraud Identifier: Misappropriation of Assets - Lapping
Definition
This fraud occurs when the accounts receivable section of the balance sheet is altered in
order to conceal the stolen cash that is intended for payment of a receivable.
Description
Lapping involves a chain of accounting manipulation triggered by act of stealing the cash
intended for a payment of a receivable. The first receivable collected is used to cover the
theft, while the second receivable is accounted to the first to continue the cover up. This is
followed by the next cycle of using the third receivable for the second and so on in order
to conceal the initial theft.
5. Fraud Identifier: Misappropriation of Assets False Invoicing
Definition
This type of fraud occurs when an invoice is generated that does not relate to a real sale
of service or product. See also: Procurement Fraud
Description
Usually this fraud type is conducted through trick. Additional substantiation may also be
provided by the fraudulent entity to legitimize the false invoice produced. Appropriate
approval process and procedures are key to detecting false invoicing. Usually this fraud
does not involve internal staff.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 22 of 66
6. Fraud Identifier: Misappropriation of Assets Long Firm Fraud
Definition
This fraud type occurs when fraudulent individuals/companies systematically establishes
trust and positive credit history with the wholesale or service provider before placing large
orders that are fraudulent.
Description
Long firm fraud begins with the fraudulent individuals/ company places lot of small orders
and pay them promptly. This environment creates trust between the service provider and
the fraudulent entity. Having established a credit history, then the entity places large
orders without an intention to pay for the service or the product. The delivery of the
product or service is followed by prompt disappearance of the fraudulent entity, which
then resells it for unlawful benefit.
7. Fraud Identifier: Inventory Fraud
Definition
This type of fraud occurs when the inventory of the service provider is misappropriated.
This is usually sold off or stolen for personal benefit.
Description
Inventory fraud can be committed by manipulating different systems. One common way
is to manipulate the inventory records directly. Another way of committing the fraud is to
manipulate the sales or inventory depletion records which in turn results in an incorrect
inventory record. In addition, the fraud can be performed by manipulating the purchasing
records which in turn results in a wrong inventory record.
8. Fraud Identifier: CNAM Dip Fee Fraud
Definition
When terminating carriers are required to “dipinto a line information database, a fee is
generated that must be paid by the terminating carrier to the originating carrier. Calls not
answered also generate this dip fee revenue, opening a unique opportunity for fraudsters
to flood a carrier with call traffic that is canceled before answered.
Description
Every call to a U.S. telephone number that has Caller ID (CID) enabled requires that the
terminating phone company perform a lookup in one of several national databases (also
known as line information database or LIDB) that contain all the U.S. subscriber names
and numbers. This database lookup is called a CNAM (Calling Name) dip. When this
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 23 of 66
database is being accessed, ordipped’, the originating phone company gets
compensated by the terminating phone company this is commonly referred to in North
America as a CNAM dip fee (or simply, “dip fee). This compensation happens for every
call where the calling party name is displayed to the called party even if the call is not
answered. Fraud often results when multiple (potentially thousands or more) calls are
sent to a carrier to terminate, yet the call is discontinued before completion resulting in a
“dip” action, and revenue generated to the fraudster.
Similar database repositories exist throughout other regions of the world, serving caller ID
compatible technologies.
Other fraud cases are possible with CNAM 3rd party providers. These providers will
supply international callers with virtual telephone numbers and then distribute that
information to the CNAM databases within the North American market. These
organizations then share in the revenue these numbers generate from dip fees while calls
are terminated from those lines. This is a legal practice, and fraud occurs when these
numbers are misused for call flooding (and non-completion) to generate dip revenues
only.
9. Fraud Identifier: Wangiri Call Back Fraud
Definition
Wangiri (“One (ring) and cut”) fraud is believed to have originated in Japan. Wangiri
scams involve a computer using hundreds of connections to call random mobile phone
numbers. The numbers show as missed calls on the recipient’s handset. A percentage
of customers will generally call back to see who called them. The numbers they call back
are either premium rate lines with high charges, or they deliver advertising.
Description
In Wangiri Fraud a computer makes calls that automatically hang up after one ring,
leaving a notification of a missed call on most mobile handsets. If the target victim returns
the call they will most commonly receive a recorded message that will either be charged
at a premium rate, and/or it will deliver advertising. In many cases the premium rate is
charged as a flat connect fee, as opposed to MOU fee.
10. Fraud Identifier: Financial Misreporting Revenue Falsification
Definition
This fraud occurs when the financial reporting is manipulated to falsely report revenue
earned by the company in order to benefit some individuals in the company.
Description
Revenue falsification usually involves higher management of the company. Some of the
most common ways of overstating revenue are sales booked before or without
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 24 of 66
completion of delivery, sales contingencies not disclosed to the management, false sales
documents and agreements, revenue reported at gross than at net. This practice is
relatively easier to commit in environments where strict financial reporting standards are
not followed.
11. Fraud Identifier: Financial Misreporting Expense Capitalization
Definition
This fraud involves incorrectly capitalizing expenses in violations of the financial reporting
and accounting guidelines in order to incorrectly increase the profits.
Description
Account guidelines allow for companies to purchase large items as assets instead of
expenses. By wrongly reporting expenses as assets, it is possible to improve the financial
reporting. This technique enables the company to capitalize and amortize the expense
over many periods rather than recognize it in its entirety in the current period, thereby
falsely improving the performance in the current period.
Any expense capitalization typically requires authorized forms. This fraud may either
include such authorized forms not present or incorrectly authorized in terms of the level of

This fraud involves financial and accounting department of the organization.
12. Fraud Identifier: Financial Misreporting Understating Liabilities
Definition
This fraud occurs when the liabilities of the company is intentionally understated in the
financial reports in order to improve the net profit of the company.
Description
This fraud involves misstatement of the financial reports to misguide the investor
regarding the performance of the company, specifically the net profit. This fraud is usually
found within publicly-traded companies. This fraud involves intentionally reporting
reduced liabilities and expenses. This may also involve postponement of reporting of the
expenses to subsequent reporting periods.

This fraud could be used for wrongly reporting the performance of the company to
mislead the shareholders or for subsequent skimming of the cash for personal benefit. In
both cases this fraud typically involves the accounting department/ individuals and often
the auditors as well.
14. Fraud Identifier: Bribery
Definition
Bribery is a fraud of collusion, involving the offering, giving or receiving of something of
value in exchange for giving or gaining undue influence in a decision making process or
obtaining another advantage. Both the giver and the receiver of the bribe are committing
a fraud as bribery advantages both the briber - who gets an unfair advantage over others.
The bribe is the gift bestowed to influence the recipient's conduct. It may be any money,
good, right in action, property, preferment, privilege, emolument, object of value,
advantage, or merely a promise or undertaking to induce or influence the action, vote, or
influence of a person in an official or public capacity.
Description
Bribery involves offering or accepting something of value in a situation where the person
who accepts the bribe is expected to perform a service which goes beyond his or her
normal job description. It also used to gain an improper advantage over others through
the intervention of a corrupt employee. Bribery is the giving of something of value by
another party to a decision maker or decision influencer in exchange for influence in a
decision making process. There is a grey area between bribery and innocent commercial
marketing. Where does an attempt to market to or to build a professional relationship with
someone become a bribe? The practical answer is the whether the employer has
knowledge of and given approval for the person to receive the benefit offered. Without the
knowledge and consent of the employer, the chances are that the receipt of a benefit by
an employee can be viewed as a bribe, whether the benefit is being given to directly
influence a specific decision or to maintain an overall relationship.
A. Types of Bribery
Most bribery frauds fall into one of two major groups - bid or tender rigging, and kickbacks
or secret commissions. These are very similar, just different in ways of achieving the
same result.
1. Kickbacks (Secret Commissions)
Kickbacks are payments to the employee from the briber outside his terms of their
employment that are usually made for obtaining a favorable decision or influence
employer purchasing something from or selling something to the third party. It can
be summarized as "You give me this contract and I will give you money or 5% of
the profits". Kick-backs are commonly thought of as payments to gain that
influence and may be based on a percentage of orders received, or some other
basis.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 26 of 66
2. Bid/Tender-Rigging
Bid-Rigging is an employee improperly influencing the awarding of a contract
through the normal tender process. This is done by giving the third party details of
the other tenders received (giving them knowledge of the conditions to beat), and
influencing the decision maker towards the briber's tender, even though it is not
the most beneficial to the employer. Tender rigging is usually done during a
tender process for a contract of supply or the sale of a large asset or for
construction contracts, or for long term supply contracts.
The major difference between kickbacks and tender rigging is the timing and
calculation of the payment and the success factor. Neither of these factors may
make a difference to the intended results of the bribes. Both are paid to get an
unfair advantage. The challenge with detecting bribes is that no assets are stolen
from and no entries are made in the records of the business. These transactions
are outside the record keeping system of the victim.
15. Fraud Identifier: Extortion and Blackmail
Definition
Extortion
Extortion means demanding or obtaining property from another through the use of
threats, coercion, or intimidation. This can include threats of physical harm or some form
of blackmail such as threats to cause harm to one's reputation, livelihood, marriage etc.
Extortion is a crime, which involves the illegal acquisition of money, property, or favors
through the use of force, or the threat of force.
Blackmail
Blackmail is a crime of threatening to reveal embarrassing, disgraceful or damaging
facts or rumors about a person to the public, family, spouse or associates unless paid off
to not carry out the threat. It is one form of extortion which may include other threats such
as physical harm or damage to property. In common usage, blackmail involving threats to
reveal substantially true and/or false information about a person to the public, a family
member, or associates unless a demand is met.
Description
Extortion
In some states extortion has only occurred when money or property has actually changed
hands as a result of the threat. Extortion occurs when a person obtains money, valuables
or other assets from another person or entity through some form of coercion. Coercion
may include, but is not limited to, the threat of violence, damage to personal property,
ruination of reputation and the threat of an action considered unfavorable to the extorted
person. Historically, extortion was defined as an abuse of privilege on the part of a public
official who used his or her position to get money or favors, but today, people at all levels
of society could potentially commit extortion. Penalties for extortion vary, depending on
the specifics of the crime. In some countries, extortion is treated especially seriously
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 27 of 66
because it is linked with organized crime, and sometimes special laws are designed to
make it easier to prosecute and punish extortion.
Blackmail
It may be defined as coercion involving threats of physical harm, threat of criminal
prosecution, or threats for the purposes of taking the person's money or property.
Blackmail may also be considered a form of extortion. Although the two are generally
synonymous, extortion is the taking of personal property by threat of harm. It is the use of
threats to prevent another from engaging in a lawful occupation and writing libelous
letters or letters that tend to provoke a breach of the peace, as well as use of intimidation
for purposes of collecting an unpaid debt. The modus operandi of blackmail is by
threatening to reveal damaging or embarrassing information in order to coerce money or
other goods or forms of cooperation out of the victim. For blackmail to be effective, the
blackmailer must, in most cases, have physical proof of the information he or she
threatens to reveal, such as photographs or letters. The victim of blackmail is typically
threatened with exposure of his or her private life, the consequences of which can range
from embarrassing to socially devastating to legally damning. At its most serious,
blackmail may rest on the exposure of a serious crime, which would do infinitely more
damage to the victim than complying with the blackmailer. Even secret information that is
not of a criminal nature, however, can make the victim of blackmail feel that he or she has
no recourse against the crime.
Extortion vs. Blackmail
Extortion is often confused with blackmail. They are both similar crimes, but blackmail is
considered less serious. Extortion is a theft crime with an element of force. Blackmail
refers to a threat that is usually socially damaging, but the threat is usually not otherwise
illegal. The threat in blackmail is often the public revelation of specific information. Neither
extortion nor blackmail requires a threat of a criminal act, such as violence, but merely a
threat used to elicit actions, money, or property from the object of the extortion.
16. Fraud Identifier: Kidnap
Definition
Kidnap can be defined as ‘taking away or transportation of a person against the person's
will, usually to hold the person in false imprisonment, a confinement without legal
authority. This may be done for ransom or in furtherance of another crime
Description
Kidnapping is a normal business fraud Threats, telecommunications can be affected
when the kidnapper hold a hostage with the intention of forcing another person to assist
the immediate theft of valuables or concede some other form of ransom from a telecom
organization such as HLR manipulations, subscriber activations or other kind of internal
fraud. In some cases is related to crime organizations.
Types of Kidnap
A. Stranger Kidnap: Stranger kidnapping victimizes more females than males, occurs
primarily at outdoor locations, victimizes both teenagers and school-age children, is
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 28 of 66
associated with sexual assaults in the case of girl victims and robberies in the case of boy
victims (although not exclusively so), and is the type of kidnapping most likely to involve
the use of a firearm.
B. Political Kidnap: Kidnapper targets are usually public figures, ransom demands are not
conventional, (Money), Political Kidnap looks to promote a cause or a change in an
organization policy.
C. Tiger Kidnaps: A tiger kidnapping or tiger robbery is a crime in which abduction forms
part of a robbery, murder, or any other crime. A person of importance to the victim is held
hostage as collateral until the victim has met the criminal's demands.
17. Fraud Identifier: Money Laundering
Definition
Money laundering is the practice of disguising the origins of illegally-obtained money. If
successful, the money can lose its criminal identity and appear legitimate
Description
Money Laundering is a normal business fraud Threats. Illegal arms sales, smuggling, and
the activities of organized crime, including for example, drug trafficking and prostitution,
can generate huge sums. Embezzlement, insider trading, bribery and computer fraud
schemes can also produce large profits and create the incentive to "legitimize" the ill-
gotten gains through money laundering. When a criminal activity generates substantial
profits, the individual or group involved must find a way to control the funds without
attracting attention to the underlying activity or the persons involved. Criminals do this by
disguising the sources, changing the form, or moving the funds to a place where they are
less likely to attract attention. In summary, the money launderer wants to:
A. Place his illegally-obtained money in the financial system, without arousing suspicion;
B. Move the money around, often in a series of complex transactions crossing multiple
jurisdictions, so it becomes difficult to identify its original source; and
C. Then move the money back into the financial and business system, so that it appears as
legitimate funds or assets.
18. Fraud Identifier: Insider Dealing Fraud
Definition
Insider Dealing fraud occurs when an employee or company official uses confidential,
internal information to gain personal profit or other advantage. This may be in the form of
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 29 of 66
pricing policies, business or market strategy, or other key areas of the business which
external entities would be interested in having advance knowledge.
Description
Insider Dealing focuses around a person or persons who, as a consequence of their
position in the company, have access to information that, if provided to others outside the
organization, could materially impact the outlook or strategy of the company, including
specific areas around:
1. Profitability
2. Financial position
3. Balance sheet
4. Market strategy
5. Etc.
Ultimately these impacts affect share price and/or overall value of the organization, and
as a result may carry heavy legal and civil penalties for external disclosure.
As part of an overall company strategy, all external facing communications should be
directed through a single, authorized channel within the business. Additionally, detailed
and explicit policies for information disclosure about the company to any outside entity
(person, group, business, etc.) should be created and provided to all employees.
19. Fraud Identifier: Procurement Fraud
Definition
Procurement Fraud is defined as the inflated or otherwise altered pricing that is presented
to a receiving company for payment. In fact, the inflated pricing is designed to pay a
dividend, benefit, or kickback” to a party within the receiving organization, as discrete
compensation for the purchase. See also Misappropriation of Assets False
Invoicing
Description
While this practice is seen throughout employee ranks of an organization, Procurement
(or contract) fraud is most relevant to senior company officers, and is probably the least
visible and most costly to the organization. This fraud is frequently a hidden byproduct of
seemingly legitimate transactions, often involving millions of dollars, between the telecom
carrier and a supposedly legitimate vendor. Very specific examples of this exist
throughout telecom operators, especially in developing markets, and most prominently in
countries where government-owned operators have far less audit control and mandate.
Audit entities worldwide have reported cases of discovered procurement fraud, however
many carriers elect to not publish the findings due to risk of prosecution, poor customer
relations, or other adverse results.
Most common procurement fraud involves an employee working with an outside vendor
to award a contract or other purchase. The employee, as a discrete condition of the
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 30 of 66
award, instructs the vendor to inflate the invoice(s), and to deposit the additional payment
into an offshore account in that employee’s name (or holding entity). Generally, the most
common procurement frauds include:
Bogus or inflated invoices
Services and/or products that are not delivered
Work that is never done
Contract manipulation
Employee kickbacks
A report in 2008 by the Association of Certified Fraud Examiners (The 2008 Report to the
Nation on Occupational Fraud and Abuse) estimated that a typical organization loses a
staggering 7% of its annual revenue to occupational fraud (including Procurement fraud).
While this report encompassed more that telecoms, the impact is an almost trillion dollar
fraud loss to a developed market (e.g., the United States).
20. Fraud Identifier: Payroll Fraud
Definition
Payroll fraud is fraud committed by an employee on their employer in the course of their
employment. As a group they are more common and cause more financial loss in total to
businesses than other third party frauds. As employees will continue to work at the
business, they will generally try to hide these frauds permanently, meaning that
occupational fraud can be committed over an extended period of time. This is an
occupational fraud where an employee attacks the payroll system of a business. They
include schemes against the salaries and wages payment systems and the expense
reimbursement systems.
Description
Payroll fraud is one type of occupational fraud. This type of fraud can also be classified as
asset misappropriation-cash that is disbursed in a fraudulent manner. There are several
schemes associated with payroll fraud and the most prevalent is ghost employee
schemes.
GHOST EMPLOYEES
A ghost employee is non-existent employees on the payroll, or someone recorded on the
payroll system, but that does not work for the business. The ghost can be a real person
that is placed into the payroll system, or a fictitious person invented by the fraudster. The
aim of the fraud is to have a wage paid to the ghost and collected by the fraudster. The
system does not require an accomplice to act as the ghost, but depending on the method
of payment (cash, check or direct deposit of wages), an accomplice may make the fraud
easier to commit, as it will eliminate the need to convert the payment from the ghost to
the fraudster. The main factor that hides this scheme is size. There will have to be
sufficient employees on the records for another not to be noticed. Size is also the greatest
deterrent against this fraud. After a certain number of employees, the business will have
to have a larger Human Resource division. After that critical size, separation of Human
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 31 of 66
Resource activities will come into play. To make a ghost employee scheme work, four
activities must occur:
1. A ghost must be added to the payroll
2. Time information must be added
3. They must be paid by the victim
4. The payment must be received by the perpetrator
Adding ghost employees to the register may be as simple as using the 'Add Employee'
function in the payroll system. In this way ghosts may be added without the normal
authorization paperwork. Otherwise the employee will have to circumvent the controls in
place in some other manner to get the ghost on the payroll.
If the ghost is paid a wage, time sheets or other wage information will have to be created
as required. It is easier to make the ghost a salaried employee or similar so that this
information will not be needed and constant maintenance of the fraud is not required.
Once the ghost has been added to the system, the salary payment should be
automatically generated. Adding the ghost can be accomplished by different means,
depending on the internal controls in place, the ghost could be added by an employee
within or outside the payroll department. Any payroll department employee with access to
the payroll records and/or payroll software could potentially create ghost employees.
Internal controls that would help mitigate ghost employees range from simple precautions
to detailed procedures. For the payroll fraud mentioned earlier involving children of the
perpetrators, simply requiring the employees to show identification when picking up their
paychecks could expose ghost employees. Frequently changing passwords for payroll
access can help prevent fraudulent entries as well as requiring payroll employees to take
an annual vacation. Additionally, print a list of all new employees each week, and have a
person not responsible for initiating new employees confirm those names with the
employee's supervisor.
21. Fraud Identifier: Expense Fraud (False Claims)
Definition
Expense frauds are committed by dishonest employees that are aimed at attacking the
payroll and expense reimbursement system of a business. They fall into two main areas,
false claims for expenses, and false claims for wages. False expense claims arise when
employees who are entitled to be reimbursed for expenses incurred while performing
their work duties, claim expenses to which they are not entitled.
Description
False wages claims arise when employees who are paid on an hourly rate or
remunerated on some basis other than a salary, manipulate the system to falsely
increase their remuneration. Expense claim frauds are usually smaller than other
occupational frauds as the amount of the expenses that may be reimbursed to
employees are generally small - but they may be common and occur over long periods.
Claims for reimbursements may be approved by someone who has no knowledge of
what amount the expenses should be, or whether the expense was incurred at all.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 32 of 66
Usually there is no need to hide the false claims once they have been paid. Like billing
schemes, the conduct of the fraud itself makes the transaction look like a legitimate
business expense. In effect, the fraud is hidden in plain sight in the records of the
business. The fact that the employee does not need to hide the theft of the money makes
it more appealing to do than simply stealing money, where the employee usually must
hide it.
Generally the more senior the employee making the reimbursement claim, the less likely
that the claim will be questioned. If that senior employee has access to the
reimbursement process and can manipulate the records, a fraud will be difficult to locate,
even if anyone decided to check the claims. The common ways to commit this fraud are:
1. Generating false documentation; and
2. Filling out blank receipts.
One popular method is to do over-purchasing (inflated claims). Over-purchasing is
purchasing too much of what is required or a more expensive item in the first instance
and obtaining a receipt for that larger amount. The employee then returns some of the
more expensive item, and obtains a refund. If needed, a less expensive version is
purchased to replace the more expensive one. A claim is made for the greater amount,
and the difference between the smaller actual amount purchased and the larger amount
of the reimbursement is the gain to the fraudster.
Some businesses have no claim approval process at all. Expenses under a certain
amount may be paid without any verification. This is usually done for expedience and
cost saving on the basis that the claims are small and not worth examining. But the
amount of an ongoing loss may grow to be significant over time. Most businesses that do
not have regular expense claims made by employees have very few procedures to
control reimbursements. Some will perceive it as a waste of resources. Added to that
attitude, controls that are in place may be ignored when the expense is charged to a
client. This is justified on the basis that the cost is not borne by the business and any
improper increase will not cause a loss. This attitude will lead to the business to be less
caring whether fraud is committed as they are not the ultimate victim. Most controls that
are put in place are nothing more than providing a receipt to the appropriate clerk and
possibly completing a short reimbursement request form. Further checks may not be
made, unless the expense is particularly significant in size or very out of the ordinary.
These frauds are usually committed when a number of employees are making expense
claims on a regular basis, or when the dishonest employee is making regular legitimate
claims. The business will be expecting claims and the volume would help to hide any
false claims. Inflating other employee's expense claims is usually done by the person
processing reimbursement claims and without the knowledge of the other employee. That
person increases the legitimate expense claim of another employee, draws the payment
at the higher amount, pays the employee the proper lower amount and then keeps the
difference. Generating false but professional looking documentation can be done with
any personal computer or photocopier. False documents are submitted as genuine
claims. One form of this fraud is for the perpetrator to write personal checks for what
looked like business expenses, attach photocopies of these checks to the false
documentation to make it look like they have paid the expense, and request
reimbursement. The checks were never used, the purchase was never made, but the
reimbursement is paid. Blank receipts can be obtained or stolen from vendors and
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 33 of 66
service providers. The easiest blank receipts to obtain are from taxi as they are hand
written on the back of their business cards. There is no difficulty in obtaining a number of
these blank receipts without suspicion. Some businesses still use off-the-shelf invoice
books. These can be purchased by anyone at any news agency. False claims can be
made in the perpetrator's name or, if the perpetrator has the required access, in the name
of another employee.
22. Fraud Identifier: Treasury Fraud
Definition
Treasury, by definition, is where the money is, where the corporation's cash is guarded
and managed. It is also where the money can be lost. Therefore, protecting the
company's financial assets from fraud starts with a secure treasury. To ensure that only
legitimate, authorized transactions occur, treasury managers must design and enforce
procedures and controls that will prevent the fraudulent diversion of funds. And because
treasury professionals have the greatest opportunities to misappropriate funds, treasury
security must be especially tight.
Description
A trusted treasury employee who takes advantage of a gap in or breakdown of security
measures can do irreparable harm. When employees have access to large amounts of
money, the financial loss can be staggering. The recent downsizing of many treasury
departments may have concentrated responsibility and increased workloads to the point
where embezzlement is more likely to occur. Productivity improvements may even have
inadvertently eliminated "redundancies" that were important checks against internal fraud.
As a result, newly "lean" treasury departments have special reasons to review their
exposures to internal fraud to make sure they are still secure. How can treasury
professionals enforce tight security in their departments? They should concentrate on
three areas:
The receipt and processing of incoming payments,
Electronic disbursements
Check disbursements.
Although security analysis often focuses on disbursements, the flow of payments into the
company also represents an important and vulnerable stream that must be protected by a
carefully planned program. The theft of incoming payments not only deprives the
company of working capital, it also may lead to huge public and investor relations
problems. Employees can steal incoming payments from the mail before it is delivered to
the company or after it is delivered but before payments are deposited into the company's
accounts. Companies can reduce their exposure to these losses by implementing dual
control procedures for mail collection and in-house processing or by using a lockbox for
remittance processing.

23. Fraud Identifier: Bypass - Tromboning
Definition
Tromboning (i.e. delivering unauthorized traffic across restricted trunks) is widely used in
Arbitrage and for the sake of By-pass; carried out by fraudulent carriers.
Basically, tromboning is where RTP media traffic originates at a certain point, and follows
a path out into the network and back to a destination close to where the RTP traffic
originated.
Description
In the richness and complexity of today's networks, especially in VOIP networks, the way
to transfer any kind of data between 2 peers is enormous and has many paths.
In order to transfer this data, the network will direct the data between the shortest paths
available within the network.
In a tromboning action, the servers may be configured to force the RTP media to go
through the server itself instead of flowing over the shortest path between endpoint- and
that is called tromboning.
Tromboning is another way of bypassing "regular" paths in the network in order to lower
costs.
24. Fraud Identifier: Bypass SIM Boxes
Definition
An apparatus (incl. s/w) housing several SIM cards (pre or postpaid) used to generate
many concurrent mobile calls. Legally used by mobile operator to test networks, un-
officially used for incoming (terminating) by-pass activities. Can swap IMEIs and IMSIs.
Can be controlled from remote
Description
SIM box operators exploit the difference between termination rates (which are often
regulated) and cheapest on-net rates.
SIM box has the ability to intercept a call and set a new on-net call, this in order to lower
the cost of the call.
By intercepting and re-doing the call, the SIM box transfers the call from the originating
network, to a mobile number of the domestic operators and creates a cheaper call.
For each of these calls there is a net loss, due to the bypassing of original routes, But the
termination network usually does not mind as it receives the interconnect fee anyhow.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 35 of 66
Important to note that such transition often affects the Quality of call and QOS as a whole.
Impact on quality of service will take place as:
- There is no CLI
- Recall and voicemail functionality often are jeopardized
- Inbound roamers are not reachable
- Call quality is highly affected
As far as the network is considered:
- High concentration of traffic
- Impact on quality to all users
- Incorrect statistics on international calls
25. Fraud Identifier: Bypass Fixed Cell Terminals
Definition
Fix cell terminals offer access from otherwise landline services to cellular networks. The
intent is often to re-route landline traffic to less expensive wireless transport.
Description
Several manufacturers offer fixed cell terminals as a legal, viable alternative to expensive
landline calling, however in some regions this practice is considered fraudulent. A fixed
cell terminal is often connected to a PBX (or similar) system, and in organizations with
high volumes of outgoing traffic, especially traffic crossing LATA and Interconnect
boundaries, cost savings by sending the traffic via CDMA/GSM instead of fixed
lines/trunks, can be substantial.
26. Fraud Identifier: Bypass - Premicells
Definition
A Premicell is a device that is capable of routing an outbound (typically landline) call over
the cheapest route within a cellular network.
Description
Premicell devices route a call over whichever network is the cheapest, based on whether
it is local or long distance, time of day and whether the destination is a landline or a
mobile number.
Premicells often pit landline operators against mobile operators (and premicell
manufacturers), as mobile operators claim they have the right to help corporate
customers slash their phone bills by using least-cost routing practices offered via
premicell equipment. Fixed line carriers in many regions are in legal battles to have this
practice declared illegal.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 36 of 66
The practice lets a company install a premicell device to its switchboard to divert calls off
traditional landlines and on to the cellular networks. It is so popular that in some regions it
is reported that up to 90% of the largest enterprise customers are engaged in this practice
to some extent. Mobile operators have claimed that the average company can slash 15%
to 20% off its monthly bills by employing this technology.
27. Fraud Identifier: Bypass GSM/UMTS Gateways
Definition
GSM/UMTS gateways are Devices that allow a call on a fixed line network to be
connected directly to a mobile network .By "bridging" the 2 networks these devices offer a
way to exploit price differentials of a mobile network provider.
Description
The GSM gateways are stuffed with SIM cards, placed in a steady place that receives
service from a specific cell site, in order to connect to the network, instead of using a
normal fixed interconnection between the networks.
Instead of paying the full price to determinate an interconnect call legitimately, the
fraudster instead pays the retails costs of a local call.
The affected operator here is the mobile operator, that is losing some of its revenues.
Also, concentrating such high volume of traffic under a specific cell site might jeopardize
its performance.
28. Fraud Identifier: Bypass Landing Fraud
Definition
Landing Fraud occurs when a call islandedon a carrier’s network in a way that avoids
toll charges. This is accomplished by making the traffic appear to have originated locally,
or otherwise within the carrier’s network.
Description
Landing off-net calls onto a mobile operator's network, normally through the use of a SIM
box, avoids the GSM gateway and thereby evades the GSM interconnect charge. GSM
Gateway Fraud is a thread and problem evolving new business models. The low cost of
set-up permits to deploy it anywhere where internet available and thus increase the
exploit and chance of damaging interconnect fees between carrier.
Rerouting calls via landing will not only bypass regular routes (and thus avoid toll billing),
but it can also jeopardize the network by providing low quality of calls, low quality of
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 37 of 66
service and even affect the network performance when a specific GSM gateway will
overpower a cell site.
Landing fraud via fixed line services is accomplished via VoIP and PBX equipment,
where voice traffic is extracted off the internet and exited out into a PSTN network via a
PBX system.
29. Fraud Identifier: Bypass VoIP Bypass
Definition
VoIP (Voice over Internet Protocol) bypass is most commonly a situation where traffic
that would normally terminate on a local network via interconnect trunk routes has instead
entered the network via an IP path, now appearing as local originated traffic.
Description
While VoIP traffic is becoming more prevalent today (computer-to-computer, computer-
to-landline, landline-to-computer, etc.), VoIP traffic that is entering and terminating on a
home carrier’s network through fraudulent means is a significant threat to carrier
revenues overall. Traffic transiting between carriers typically enters and exits carriers via
gateways, and carriers have detailed agreements with their surrounding partners on rates
for minutes of use for either terminating or otherwise transporting the originating carrier’s
traffic. In the case of bypass, two forms have existed:
1. Legacy Bypass: Carrier A and Carrier B have agreements in place to carry
and/or terminate each other’s traffic, and have contracts that outline settlement
reimbursement schedules with each other. However, Carrier C has negotiated a
cheaper termination rate with Carrier A. Carrier C then may approach carrier B
and offer them a cheaper rate to get the same traffic to Carrier A’s network. As a
result, Carrier B will lower its expense, and Carrier A’s revenues will similarly
decrease. Legality questions around this practice vary based on region,
regulations, etc.
2. VoIP Bypass: In the similar case of the same two carriers, A and B, Carrier B has
moved a portion of its traffic destined for Carrier A to an IP network. Carrier B will
most likely have access to an exit point (SIM box or PBX) where the traffic leaves
IP and returns to SS7-based facilities within Carrier A’s home network transport
area. For all traffic now routed via IP into Carrier A’s network, this traffic appears
as local to Carrier A, and thus no settlement is billed to Carrier B. At the same
time, Carrier B is still able to bill their event originators at full interconnect rates.
Prevalent Methods for IP to SS7 traffic transfer:
1. SIM Box in this case, multiple SIMs are loaded into aSIM Box” which acts
similar to a PBX, yet moves IP voice traffic out to mobile networks for termination
on either mobile or fixed line equipment.
2. PBX this is a common approach to move IP voice traffic out to local fixed line
networks. Due to the general acceptance and availability of PBX platforms, this is
often a far easier method to move IP traffic to SS7 networks undetected.

Risks to Carrier A:
1. Loss of interconnect revenues the carrier has terminated interconnect traffic
unknowingly.
2. Increase in traffic overall in these cases, to avoid detection, Carrier B may not
decrease common settle traffic volumes via SS7-based networks, however
Carrier B may engage in aggressive campaigns (to enterprises, other carrier
partners, etc.) to increase traffic is may send via IP.
Detection Method(s)
Bypass in general tends to pattern itself with call traffic that is unbalanced, with much
more emphasis on termination traffic.
30. Fraud Identifier: Bypass Interconnect Fraud
Definition
Interconnect fraud involves the manipulation, falsification or removal of records by
operators to deliberately miscalculate the money owed by one Telco to another. There
are many forms of Interconnect fraud including:
- Interconnect peer inflates traffic figures to be paid more
- Arbitrage
- Tromboning
Description
Interconnect fraud appears in all sorts of forms, as described in this document, but the
basis of all of them and the focus of attention will be an effort of one company to
manipulate data of existing traffic, and disguise it by removal of files, sending in correct
data etc.' in order to create a misleading picture of a lesser volume of traffic- in order to
pay less to the specific interconnect partner on which the manipulation has been done.
31. Fraud Identifier: Bypass Toll Bypass
Definition
Toll bypass allows customers to bypass the PSTN network, and the associated toll
charge. Toll Bypass is very similar to Landing Fraud, except the traffic may not enter the
PSTN network at all in a Toll Bypass situation.
Description
The PSTN network consists of the tandem time-division multiplexing (TDM) based
switches used for long-distance (or toll) voice calls. Enterprise customers who typically
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 39 of 66
depend on the PSTN for their interoffice (intra calls) voice traffic avoid toll charges by
using an IP network with routers that serve as the edge voice gateways.
Toll bypass allows some Internet service providers (ISPs) to offer residential customers
free, or very low-cost, long-distance voice calls by routing the calls over an IP network.
32. Fraud Identifier: Bypass Third Country
Definition
Third Country Bypass fraud can be found mostly in messaging (SMS, MMS), although it
does also exist in voice traffic scenarios, where the originator of messages (or traffic)
spoof the origination IDs to a 3rd country/operator, which is later charged for the traffic.
Description
Third Country Bypass fraud occurs when the fraudster has the ability to alter the traffic
origination information, thus causing a different entity to be billed for the traffic. In mobile
SMS and MMS environments, spoofing of the origination ID of the message is the
primary method, while in voice services, CDR traffic may be altered to show either a
different origination point (home operator), of the origination point may be obscured all
together. In those cases where origination points are obscured, intermediate parties
carrying the traffic may be inadvertently billed for the call, with no carrier recourse.
33. Fraud Identifier: Bypass Grey Routing
Definition
Grey Route is the arrangements that fall outside the regular course of business between
the licensed telecoms companies in each country. The grey part of the route is usually
realized at the far end where the call is terminated. Up to that point, the call is delivered
normally and the call transfers from the subscriber to the sending carrier and then to the
sending carrier and the satellite or cable operator for the trunk part of the call. The 'grey'-
ness arises because the terminating end the call is made to appear as if it originates
locally, as a domestic call, or arrives as an internet delivered call, rather than a more
expensive standard international call.
Description
Gateway operators deliberately route international voice calls in an effort to avoid higher
operator charges at the respective interconnection points. The most common method
uses a GSM gateway (e.g., SIM box’ orGSM Router’) to terminate VOIP on an
operator’s network as a local call. Similarly in fixed networks, switch bypass operators
may use a TDM Gateway, PBX, and/or other methods to terminate VOIP on an
operator’s networks as a local call.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 40 of 66
In most situations, the "grey route" operator brings international traffic over the internet
and terminates them as local calls on the GSM or Fixed operator's network, denying the
operator the international termination rates.
Grey routing is also known as switch bypass fraud. This practice has maintained a very
low barrier to entry due to global internet connectivity, plug-and-play equipment and the
emergence of 24/7 minute trading while countries are working to make this practice
illegal, in many regions the legality of this method of bypass is still not fully defined.
34. Fraud Identifier: Bypass International Simple Resale
Definition
Involves landing off-net calls onto an operator's network but avoiding the international
gateway to avoid the International interconnect charges.
Description
International Simple Resale or ISR, is also a form of Interconnect Fraud. ISR involves
landing off-net calls onto an operators network but avoiding the international gateway to
evade the international interconnect charge.
A variant of ISR, known as GSM Bypass, involves landing off-net calls onto a mobile
operators network, normally through the use of a SIM box, avoiding the GSM gateway
and thereby evading the GSM interconnect charge. This is further explained in “Landing
Fraudin chapter 29.
35. Fraud Identifier: Missing Trade Fraud
Definition
Missing trader fraud is stealing large amounts of Value Added Tax (VAT) from a
government by organized crime gangs who exploit the way VAT is treated within multi-
jurisdictional trading where the movement of goods between jurisdictions is VAT-free The
fraudsters steal money that could be used for essential public services.
Description
Missing Trade Fraud is a normal business fraud Threats. The simplest missing trader
fraud is where a fraudster imports some goods, and then sells them. When he sells them,
he charges the price of the goods, plus VAT. He then absconds with the VAT instead of
paying it to the Government. This situation, where the goods are made available for
consumers in the importer's home market is often known as 'acquisition fraud'. In
telecommunications typically involves goods such as mobile phones and computer parts.

36. Fraud Identifier: Carrousel Fraud
Definition
Carrousel Fraud is an evolution of "Missing Trader Fraud", in this situation, the goods are
sold to a series of companies, before being exported again. The goods therefore go
round in a 'carousel'. These companies are called "buffer". In a real case there can be
many buffers, all helping to blur the link between the final reclaim and the original
importer, which will vanish.
This entire series of transactions can occur without the goods ever leaving the dock
before being re-exported. Furthermore the same goods (telephones or computer parts for
example) can be used again and again going through the various buffers, each pass
around the 'carousel' bringing reclaimed VAT to the fraudsters.
Description
The typical carousel fraud usually operates in the following way:
Company A, in one EU member state, sells goods to company B in another member
state, Company B either a defaulting trader or a trader employing a hijacked VAT number
sells the goods on at a discount to a company C in the other member state. C is a buffer
company that can therefore make further sales at a profit. Company B incurs a liability to
VAT on the purchase of the goods (acquisition tax), but as it has used those goods for
taxable transactions, it is also entitled to deduct that VAT as input tax. Although it has
incurred VAT liability on the output tax it has charged to company C, company B goes
missing before discharging that liability to the tax authorities. Buffer Company C then sells
the goods on to another buffer company D, also in the other member state, paying the
authorities the output tax it charged, after deduction of the input tax it has paid. This
continues until a company in the second member state exports the goods to another EU
member state. While exports are exempt from VAT, the exporting company is entitled to
claim a refund of the input tax it paid on the purchase of the goods. Should the purchaser
in the last member state turn out to be company A.
37. Fraud Identifier: Roaming Fraud
Definition
Roaming Fraud is the use of telecom products or services, such as voice or data
services, outside the home network with no intention to pay for it. In these cases
fraudsters exploit the longer time-frames required for the home network to gain visibility of
usage by its customers.
Description
Roaming fraud can starts as an internal or subscription fraud in the home network, when
obtained sim cards are sent to a foreign network the fraud or abuse starts. Roaming
Fraud is related to other fraud types such as International Revenue Share Fraud, Call
Selling, Call to Premium Rate Numbers,

38. Fraud Identifier: Cloning Fraud
Definition
A cloned cell phone is one that has been reprogrammed to access to a cellular network
as a legitimate cell phone. The legitimate phone user then gets billed for the cloned
phone’s calls.
Description
Cloning has been shown to be successful in TDMA/ CDMA Networks, but rare on GSM.
However, cloning GSM phones is achieved by cloning the SIM card contained within, not
necessarily any of the phone's internal data (GSM phones do not have ESN or MIN, only
an IMEI number.) There are various methods used to obtain the ESN and MIN; the most
common are to crack the cellular company, or eavesdrop on the cellular network.
39. Fraud Identifier: Spam Malware Fraud
Definition
Spam-Malware fraud is perpetrated when a spam event (email, text, advertisement, etc.)
is received by the victim, and contains link(s) disguised as a trusted sites, yet contain
damaging malware.
Description
Spam appears in most environments with telecommunication products today. In mobile
text events, internet sites, internet advertisements, and email, spam has been inserted by
persons and organizations to encourage viewers to access the link(s) contained within
the spam. These links most often lead to malware.
Spam-Malware example: In blog spam, comments to the blog sometimes try to entice
people to go to another site. The site being advertised may simply be trying to boost its
search engine rankings to generate more ad revenue, however more often the site has
malicious results by activating malware (e.g., a virus).
40. Fraud Identifier: Spam Spoofing Fraud
Definition
Spam Spoofing Fraud is the case of an unwanted or unsolicited message being
delivered to the recipient, with the sender appearing to be someone else.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 43 of 66
Description
Spam is commonly defined as unsolicited bulk messages (email, SMS, etc.). Year on
year, users are reporting increasing amounts of received spam, and most consider spam
a significant problem.
There are generally two types of spam: Intentional and Unintentional. Intentional
spam comes from spammers who are soliciting products or attempting to commit fraud.
Unintentional spam originates from computers and mobile devices that are infected with a
virus or worm that activates e-mail or text distribution processes in the background. The
virus or worm attempts to send bulk messages from the infected device without the
awareness of the computer owner.
Spoofing occurs when the sender of an e-mail message pretends to be someone else.
Spoofing is often used by spammers by simply changing the "FROM" e-mail address.
Spoofing may occur in different forms, but all have a similar result: A user receives a
message that appears to have originated from one source when it actually was sent from
another source. Spoofing is often an attempt to trick the user into releasing personal (or
sensitive) information, making a damaging statement, or allowing access to additional
recipient contact information.
41. Fraud Identifier: Spam IP/Phishing Fraud
Definition
Spam IP/Phishing Fraud is defined as an attempt to trick the user into entering personal
information (accounts, passwords, etc.) for the purpose of identity theft. Phishing often
appears as a legitimate message from a known entity (e.g., victim’s bank).
Description
Spam is commonly defined as unsolicited bulk messages (email, SMS, etc.). Year on
year, users are reporting increasing amounts of received spam, and most consider spam
a significant problem.
There are generally two types of spam: Intentional and Unintentional. Intentional
spam comes from spammers who are soliciting products or attempting to commit fraud.
Unintentional spam originates from computers and mobile devices that are infected with a
virus or worm that activates e-mail or text distribution processes in the background. The
virus or worm attempts to send bulk messages from the infected device without the
awareness of the computer owner.
Phishing is a special type of spam that is intended to trick the victim into entering
personal information (account numbers, passwords, etc.) for the purpose of breaching the
victim’s account and committing identity theft or fraud.
In a typical Phishing scenario, a false message is delivered to you via email or text. The
message appears to come from a legitimate source (see spoofing in the previous fraud
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 44 of 66
section), but in fact the message is a scam. The message may contain a legitimate
corporation's logo, and appear to be sent from the corporation's e-mail address. The
message may appear exactly as previous legitimate corporation messages. The
message may ask you to click a link in the message to update your account, or run a
software program to upgrade your computer.
Although the message looks legitimate, it is really trying to compel users to submit
personal and confidential information, which will be used to steal credentials. Normally
users are asked to enter information such as name, date of birth, place of birth, social
security number, mother's maiden name, bank account number, and bank account PIN.
Virtually all internet service providers have been the targets of phishing scams. Today
most internet-accessible (and provider) organizations state that they will never ask for
disclosure of personal information via a message correspondence.
42. Fraud Identifier: (International) Revenue Share Fraud (IRSF)
Definition
IRSF is generally initiated by fraudulent traffic activity generated on a network that causes
payments to another network or PRS provider, however the subsequent revenues will not
be collect for those events.
Description
RSF is more commonly captured as ISRF (International Revenue Share Fraud), as most
instances have been related to SIM card cloning activity. In general, RSF follows a
particular path:
1. Cloning or otherwise unlawful acquisition of service (SIM cloning, PBX hacking,
etc.)
2. Consumption of service (voice calls, PRS events, etc.) involving a partner
network or PRS provider.
a. Consumption of service in SIM cloning usually involves moving SIMs to a
roaming network, and purchasing PRS services, causing payment to an
often fraudulent 3rd party from that roaming carrier.
b. Consumption of service in PBX hacking often involves calls being made
to premium toll services operated by fraudulent 3rd parties. This results in
toll charges being paid by the carrier and/or the enterprise which owns the
PBX.
3. Activity is generally short term on any given SIM identification or PBX line,
depending on detection technology available.
Detection Method(s)
1. Velocity Monitoring Witnessing events belonging to the same SIM identifier
which are geographically distant yet within a close timeframe (e.g., 2 events
happening from the same GSM handset, 1000 km apart, with 10 minutes of event
start time.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 45 of 66
2. Event overlap Similar in concept to Velocity, subscriber is detected executing 2
events simultaneously or overlapping in time, from different locations.
3. IMEI Change A subscriber is changing their device (IMEI) several times within a
certain time period (detected by xDR traffic IMEI identifiers from same subscriber)
4. Location Updates Suspicious subscribers and past cloning suspects are
monitored for location velocity issues daily.
5. NRTRDE Monitoring Near Real Time Roaming Data Exchange (NRTRDE)
traffic is monitored for overlap and velocity events. Latency of data (within 1-3
hours) may result in moderate losses before data is captured and analyzed.
6. CAMEL Monitoring Typically a faster path than NRTRDE (Near Real Time
Roaming Data Exchange); CAMEL Monitoring facilitates monitoring of current
MOC/MTC traffic of roaming subscribers, to quickly detect overlap and velocity
situations.
7. Proactive Clone Detection (PDC) The practice of comparing authentication of
services across multiple geographies, to look for cloning incident. This practice
may heavily reduce event losses if processes are in place to quickly detect and
suspend cloned equipment.
43. Fraud Identifier: PBX Hacking Fraud
Definition
PBX (Private Branch Exchange) hacking incidents typically occur when the PBX is
directly accessible (business facility is unattended), the PBX usage is not monitored, or
the PBX is accessible outside the business (e.g., via IP connectivity). When hacked
(accessed through unauthorized means), call events are placed and routed via the PBX
and the business owners are unaware of the events.
Description
Several Methods of PBX hacking are most common today:
1. Brute Force Attacks: In this case the PBX security is breached via the toll-free
Direct Inward System Access (DISA) number. Many PBX systems allow dial-
through, wherein a person calling into the PBX can access an external line by
using appropriate passwords and control sequences. This feature is common in
large business environments.
a. Fraudsters hack into the PBX, obtain passwords, and then use the PBX
to generate outbound calls (often for call selling or PRS revenue share).
b. War dialing” is often used for obtaining passwords. This method involves
the fraudster using an auto dialer, which keeps on dialing the same
number, then enters a continuing, exhaustive sequence of codes until it
breaks through the password layer.
2. Default Passwords: One of the largest contributing factors in PBX hacking is
poor or incomplete PBX installation and configuration, leaving default user and
maintenance port passwords in place (fraudsters know the default passwords for
the various switch vendors). PBX fraud commonly occurs when the customer
fails to change the default password(s) or do not change passwords frequently.
Default passwords can be found online in the relevant PBX user manuals etc.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 46 of 66
3. Internal Enemy: Many cases of PBX hacking result from insiders or vendors
who disclose the phone numbers, IDs and passwords necessary for breaching
PBX security. Users may obtain passwords by unauthorized means, allowing the
use of corporate lines for making personal calls or colluding with external
fraudsters to help in PBX hacking. Strict security Policies should be in force for
PBX password control. Additionally, the physical security of PBXs and phone
extensions is also an important factor to consider in avoiding misuse of PBXs.
4. Social Engineering: The traditional (wired) phone scam involving the 90#
buttons on corporate telephone lines does still exist, mainly on older, legacy PBX
systems. In this case, employees within the business receive a call from
someone claiming to be a telephone company employee investigating technical
problems with line, or checking up on calls supposedly placed to premium rate
services or other countries from your line. The caller asks the employee to aid the
investigation by either dialing 90# (or similar combination) or transferring him/her
to an outside line before then hanging up the telephone receiver. By following
these instructions the employee will enable the fraudster to immediately place
calls that are billed to the corporate telephone account. This attack is becoming
more rare, yet it is still a relatively common technique used for obtaining
passwords.
5. Service Port: PBX hackers may also target modems or IP ports attached to the
service port of a PBX. This access is provided by PBX manufacturers to allow
remote support of the PBX. Typically, the connection should be opened only
when an authorized request goes from the PBX customer to the PBX vendor, but
many PBX customers keep the connection always open and therefore prone to
attack.
In addition to theft of service, the following misuse can occur through PBX hacking:
1. Disclosure of Information (eavesdropping on conversations, or gaining
unauthorized access to routing and address data).
2. Modifying Data (billing information changes, or system modifications to gain
access to additional services).
3. Denial of Service attacks (password changing to deny access, or forcing the PBX
to fail or degrade call quality through excessive call volume).
4. Trac Analysis such as observing information about calls, allowing inferences to be
made (industrial espionage), e.g. from the source and destination numbers, or
frequency and length of calls.
44. Fraud Identifier: IP Subscription/Identity Theft Fraud
Definition
IP Subscription/Identity Theft Fraud occurs when information related to IP address or
other IP account information is stolen from the user. The fraudster can then use the
information to hack the user’s account and/or computer, with the intent to insert malicious
software and/or steal sensitive (personal) information.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 47 of 66
Description
IP Subscription and Identity theft is very common in todays connected world, and has
made it virtually unthinkable to not have at least one form of firewall, virus, or other
protection software installed on every computer and handset today.
IP addresses reveal the location of computers, and in most residential applications today,
these are dynamically issued (each time the computer or home broadband router
appears online to the ISP). In businesses, however, static (fixed) IP addressed are
typically secured, allowing consistent VPN activity, website access, etc., to external users.
Either of these environments does facilitate attacks on the IP addresses by fraudsters,
making firewalls, secure encryption protocols, and other protection mechanisms
absolutely critical to protect the integrity of the information within the computer or network.
The problem is not just one of access from the outside to within your network or
computer; access may also be facilitated by inadvertent launching of phishing sites, or
other malware programs. This is also something virus software programs have been
designed to combat, by examining web sites (in real time with user activity), emails, and
most other forms of external communications, to immediately identify threats.
45. Fraud Identifier: IP AIT (Artificial Inflation of Traffic) Fraud
Definition
AIT (Artificial Inflation of Traffic) is the practice of increasing traffic that incurs charges to
originating customers and operators, with payments going to the fraudsters (at least in
part).
Description
AIT takes place over premium rate and revenue share (where terminating operator
receives a share of the billed revenue) numbers which typically have a cost to the
customer. In the case of AIT, the owner of these destination number ranges aims to
inflate the traffic for financial gain all at little or no cost to himself.
This increase in traffic can be in the form of spam or missed calls encouraging people to
ring a certain number, exploiting a gap in billing systems or through auto-dialers.
Some premium rate and revenue share numbers are charged to the caller on a so called
“single dropbasis regardless of the call duration. This leads to frauds involving very short
calls, either to generate very large amounts of traffic as part of subscription fraud or to
defeat the billing system at the originating point.
AIT is also seen in PRS environments where tiered pricing strategies are employed. In
this case, as volume of use of the PRS service increases, higher discount “tier” levels are
reached which translates into more revenue for the PRS provider. This has resulted in
many cases of AIT as the PRS provider approaches another tier level within a billing
period.

46. Fraud Identifier: IP DoS (Denial of Service) Fraud
Definition
Denial of Service (also known as Distributed Denial of Service, or DDoS) is the intentional
flooding” of traffic to a target web site, network, etc., to render the target disabled or
otherwise unable to function properly.
Description
A denial-of-service attack (DoS attack) or distributed denial of service attack (DDoS
attack) is an attempt to make a computer resource unavailable to its intended users.
Although the methods used, the motives, and targets of a DoS attack may vary, it is
typically the coordinated efforts of a person, or multiple people to prevent an internet site
or service from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of
DoS attacks typically target sites or services hosted on high-profile web servers such as
banks, credit card payment gateways, large enterprises, and other highly accessed web
and network environments. The term is generally used with regards to computer
networks, but is not limited to this field; for example, it is also used in reference to CPU
resource management.
One common method of attack involves saturating the target machine with external
communications requests. The volume of the inbound requests makes the target
machine unable to respond to legitimate traffic, or it responds so slowly it is rendered
ineffective or unavailable. More simply stated, DoS attacks are designed such that the
targeted computer(s) must reset, or are forced to consume internal resources so that it
can no longer provide its intended service.
47. Fraud Identifier: IP Content Sharing Fraud
Definition
IP Content Sharing fraud is defined as sharing or distribution of content by an
unauthorized entity. This may or may not be for financial gain, but the sharing (or
redistribution) of the content is in direct breach of licensing agreements.
Description
Content sharing may involve any number of services, but most commonly content is
considered to be premium products, including ringtones, music, games, movies, screen
savers, and other products for sale by the content provider or their authorized agent(s).
When procured, buyers are asked to agree to license terms as a condition of the sale;
redistribution is virtually always not permitted within these agreements, and a buyer must
agree to them in order for the sale to complete and the content to be delivered.
Commercial content sharing is a far more elaborate enterprise involving more discrete
activities, on a much higher volume. This is frequently executed over international
boundaries, as prosecution and damage recoveries are far more difficult and expensive
for content providers. Note that this is also a governmental concern, as taxes are also
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 49 of 66
usually circumvented during this fraud, costing governments substantial losses in
potential revenues.
Consumer content sharing is a prevalent practice, and not easily detected. Certain
companies have allowed limited forms of content sharing (e.g., Apple itunes) within their
end user agreements, which has benefited both users and Apple in the longer term,
however other forms of content sharing still cost the content industry enormous amounts
in terms of unrecognized revenues.
48. Fraud Identifier: IP Identity Trading Fraud
Definition
Identity Trading fraud is the practice of stealing identities of users (personal financial
information) and then offering those identities and access information for sale to other
fraudsters.
Description
Identity Trading (selling) is a highly active business globally today, with most identity
thieves offering to sell stolen identities in low-profile, often secret chat rooms and other
communication environments. These selling forums have constant streams of thieves
providing detailed information about stolen user identities, to prove they have what they
are offering for sale. Payments to the thieves may be as simple as a PayPal transaction,
and delivery as simple as email, however more volume-based and elaborate schemes
may involve monies being deposited to offshore accounts under bogus companies, and
secure transmission of considerable volumes of stolen users and their sensitive
information.
49. Fraud Identifier: IP - Spyware Fraud
Definition
IP Spyware Fraud occurs when a Spyware software is installed on the user’s computer or
handset (smartphone) without their knowledge. The spyware then collects and transmits
sensitive information to a destination for (typically) malicious purposes.
Description
Spyware is secretly introduced to the user's computer or handset. Not all spyware is
malicious, as some types may be installed deliberately by the user (or their IT
administrator) in order to track or monitor the activity of other users. This may be used in
some corporate, shared or public computer situations.
Malicious spyware (installed without the user's knowledge by an unauthorized source)
can extract data about the user or other data from their computer or handset and send it
elsewhere. It can interfere with computer operations, change settings, bring up different
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 50 of 66
home pages, cause loss of Internet service and interfere with the functioning of other
installed programs. Spyware is most often intended to monitor the activity of the user
while on the Internet.
Spyware programs can easily collect and transmit personal information. This business
intelligence is of value to advertisers and others who interested in knowing what websites
people visit and what are their Internet surfing habits. More malicious spyware can even
redirect browser input to land the user on a different website than the user intended.
Because of its intent to transmit information without user knowledge, spyware is classified
as privacy-invasive software.
Spyware is often coupled with adware (advertising-supported software). By clicking the
adware, this allows the spyware to infect the computer without the user's knowledge. The
result of an infection is that the user's computer will run slower and there will often be
many pop-up ads that appear. While spyware and adware may then simply introduce
general (pre-defined) advertising, pop-ups, etc., more “intelligentspyware and adware
use the information collected about the user's Internet browsing to put up ads that are
directly related to that browsing behavior.
Spyware also reports user activity to third parties. This can be reports about which
websites a user visits, the number of visits and activity while on a website. This all occurs
in the background while the user is actively browsing. The security problems involving
spyware have generated an entire new industry devoted to foiling spyware and adware
programs. Spyware has been used to steal identity information and credit card numbers.
50. Fraud Identifier: IP Pharming Fraud
Definition
Pharming is an attack on a computer or handset with the intent of redirecting a website's
traffic to another, bogus website. Pharming may be the result of a malicious change to
the hosts file on a victim’s computer, or by the attack of a vulnerable DNS server.
Description
The most common places for pharming attacks are within a computer’s hosts file. The
hosts file avoids website name lookup with its own local name to IP address mapping.
Once changed via the attack, a legitimate request for a sensitive website can direct the
user to a fraudulent copy. Personal computers are often better targets for pharming
because they receive poorer administration than most internet servers.
Local network routers may also be attacked by pharming malware. Since the router
typically serves many devices, this is cause for more serious concern. Many routers
specify a trusted DNS to users as they join the network, therefore a redirection of IP
destination here will affect all users within the LAN. Router compromise is more difficult
to detect. Routers can pass bad DNS information in two ways: Malconfiguration of
existing settings or complete rewrite of firmware. Nearly every router allows its
administrator to specify a particular trusted DNS in place of the one suggested by an
upstream location (e.g., the service provider). A pharming attack could specify access of
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 51 of 66
a DNS server under the attacker’s control instead of a legitimate one. All subsequent
name resolutions will go through the bad server.
Additionally, many routers allow the replacement of their firmware. This is common in
upgrade scenarios. Firmware replacement can be very difficult to detect good
implementations of pharming malware will appear to behave the same as the
manufacturer's firmware: Settings, administration menus, page look and feel, etc., will
appear the same.
51. Fraud Identifier: IP Online Brand Threats Fraud
Definition
Online Brand Threat fraud occurs when a specific brand is counterfeited and offered for
sale as the genuine product. Several forms of online brand threats exist; not all are
fraudulent, and are described in more detail below.
Description
Online Brand Theft fraud is most commonly a deliberate attempt to either sell a
counterfeit product under the guise as genuine, or to otherwise falsely damage the
reputation of the product for some financial gain (e.g., a competitor). In some cases,
competitors have virtually “cut and paste product claims into their own materials and web
sites, even though there is no basis in fact in their claims. The illegality of thiscut and
pastepractice is still in question in many jurisdictions, however.
Specific examples of online brand threats (not necessarily fraudulent) include:
1. Counterfeit Product: To take advantage of a market-leading brand, counterfeit
products are introduced and sold as the genuine product. These counterfeits will
look virtually identical, and not only will harm the sales of the original product, but
also may cause brand dissatisfaction and poor brand perception should they not
offer the same quality and reliability of the genuine product.
2. Consumer Complaint sites: These sites are often formed by disgruntled or
otherwise unhappy customers of the target product and company. This typically
invites other readers to share similar experiences, and often these sites lead to
warnings about purchasing the product. This frequently results in loss of
revenues, and even loss of customers.
3. Competition: Unethical competition often appears as the introduction of negative
publicity and comment (often inaccurate), and usually via the unregulated
channels of online blogs and customer complaint sites.
4. Social Networking: These sites are also mostly unregulated, and offer
competition and others a chance to promote negative publicity around a product,
brand, or company.

52. Fraud Identifier: Interconnect (IXC) Arbitrage Fraud
Definition
Arbitrage Fraud is defined as the routing of traffic via other carriers and/or countries to
take advantage of differences in settlement rates.
Description
Arbitrage is the practice of routing traffic via an intermediate carrier or country to take
advantage of the differences in settlement rates. If carrier B has much lower settlement
rates with carrier C than with carrier A, it might be cheaper for originating carrier A to send
its traffic destined for carrier B via carrier C. While this may be considered good business
practice, in reality it is often in direct contractual violation with the terminating carrier
and/or the international traffic regulations as established by the terminating country.
One of the first larger arbitrage routes was for traffic between Australia and the US, which
was cheaper if sent via New Zealand and Canada. Other arbitrage strategies have
included telecommunications companies allowing their customers to make international
calls without paying long-distance charges by dialing certain access numbers. The
companies engaged in this arbitrage are paid an interconnect fee by the network
operator, and then typically use part or most of this fee to buy additional international
calling routes at low prices.
53. Fraud Identifier: Interconnect (IXC) Call Looping Fraud
Definition
Call Looping Fraud is defined as the practice of disguising originating call numbers from
the terminating carrier, such that billable call activity is unrecognized, and thus unbilled.
Description
Looping is a method in which fraudsters circumvent controls in telecom networks to avoid
detection of their origination number. Looping may be accomplished by using any of
several types of devices, such as a Private Branch Exchanges (PBXs), cellular phones or
telephones that are call forwarded to an access number. These devices are all capable
of originating a second call while keeping a first call on the line. The call looping
perpetrators may loop calls through one carrier, or they may loop calls through multiple
carriers. The final result is to bypass the control(s) that would normally identify the
origination point of the call.
In a typical looping activity, the originating caller places a first call to an intermediate party
in order to avoid controls established by the carrier to protect against fraudulent calls from
the originating caller to the terminating party. The intermediate party includes a call-
origination device, such as a private branch exchange (PBX), a cell phone service or a
call forwarding telephone. If the originating caller can access the call-origination device of
the intermediate party the originating caller can place a second call on the call-origination
device to the terminating party while staying on the first call.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 53 of 66
In international or other interconnect (long distance) scenarios, call looping fraud (when
successful) makes the originating call appear as a local (in region) call, thus not billable
as a toll call to the originating caller.
54. Fraud Identifier: Interconnect (IXC) QoS (Quality of Service)
Exploitation Fraud
Definition
Quality of Service (QoS) refers to the probability of the telecommunication network
meeting a given traffic contract. Fraud in this case exists when the contracted QoS is
deliberately not delivered by the interconnect operator.
Description
While several abstract definitions exist in the market today for Interconnect Quality of
Service (QoS) Exploitation fraud, the primary focus of this fraud is the deliberate
degradation of promised service levels (by the contracted operator network), typical in
favor of other, higher revenue traffic.
Within unhealthy or poor performing networks, quality of service (QoS) management is
ineffective in managing degradation issues. On a strong performing network, QoS is
employed to help forecast growth, but otherwise not needed to alert for poor
performance. Strong networks are able to adequately supply sufficient resources to all
applications, allowing them to perform properly.
When network resources are scarce and demand is increasing beyond network capacity,
QoS exploitation occurs most commonly when the operator begins to prioritize certain
services, which will inevitably be at the cost of other services. Those “higher priority”
typically are generating the highest amount of revenue. The fraud occurs as a result of
the deliberate (and unannounced) decrease on QoS on those lower revenue carriers.
55. Fraud Identifier: Interconnect (IXC) Technical Configuration Fraud
Definition
Technical Configuration fraud is a form of internal fraud that involves the configuration of
(interconnect) routes, rate sheets, or other factors that will move traffic over more
expensive and/or non-contracted paths.
Description
Interconnect routing is a complex set of processes designed to route traffic through the
best interconnect partner. The “bestpartner may be determined by price, time of day,
quality of service, quantity of traffic, contracted volume agreements, or a blending of any
of those factors. Depending on volume, more than one carrier may be selected for a
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 54 of 66
specific route or set of routes, with traffic priorities assigned asmost favored” routing,
and on downward, resulting in the most effective routing costs and call quality for the
operator’s customer.
In cases of Technical Configuration fraud, the internal fraudster has altered the routing
configuration to favor a specific interconnect carrier’s routes, outside of agreed and
expected parameters. While this will typically benefit the fraudster financially (rewarded
by the carrier receiving the fraudulent traffic configurations), it may also have a negative
impact in terms of penalties and losses incurred by the home operator, should an audit
reveal traffic routing outside of contracted agreement.
56. Fraud Identifier: SMS Fraud
Definition
SMS Fraud generally consists of SMS message traffic being initiated that is either
unbillable (the originator of the SMS is unidentifiable - technical, spoofing, or signaling
fraud), and/or causes adverse effects to networks and recipients (e.g., malware delivery,
spamming, etc.).
Description
SMS fraudulent activity can manifest as any combination of the defined tactics. In frauds
where the originator is unbillable, weaknesses in the networks (SS7, IP, SMSC, etc.) to
either block or properly identify the originator is exploited. All originating SMS traffic is
handled by the home network of the originator, even if roaming (except in the case of
open SMSC platforms on network where the message is being originated). SMS traffic is
sent directly to the home SMSC via SS7 (or IP, in Valued Added Service Provider cases),
and message signaling is either manipulated to appear as a roaming subscriber, or to
“trick” the SMSC into believing the subscriber is someone else (a legitimate customer),
and actually registered within the home network. In either of these cases, billable events
are either unable to be attached to a customer, or an unsuspecting (uninvolved) customer
is incorrectly billed.
Malware attacks via SMS occur when embedded software within an SMS event is
inadvertently downloaded and/or activated by the receiving subscriber(s). These
malware programs may generate enormous amounts of outbound traffic from those
subscribers, collect and transfer personal information, generate automated PRS activity,
and other unwanted effects. Malware attacks also have the capability of creating DoS
(denial of service) situations due to significantly increased network activity they generate.
SMS Spamming (flooding) is also becoming a prevalent method in which fraudsters
(often using spoofed or masked identities) will generate messaging to a significant
number of subscribers. Quite frequently the message will contain a web link, a promise
of a gift or reward for calling a number, or other advertising tactics to generate a response
from the recipient. As with malware transmittals, network DoS is a significant risk with
SMS flooding.
In most (if not all) cases of spamming, flooding, and malware transmittals, Global Titling
(GT) attacks may have been used by fraudsters to query the home network for subscriber
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 55 of 66
location and identification information; this information will then be used to target
recipients with these messages.
Detection Method(s)
Large message volumes from single subscribers (or groups of subscribers) should be
closely scrutinized. Probing may also be employed to scan messages for unwanted
content (web site information, etc.).
Corrective Action(s)
A key component to all actions to correct and protect against SMS fraud is to properly
install and configure SMSC platforms with strong messaging subscriber identification
protocols, and to protect against unauthorized signaling query attacks. Messaging from
unrecognized subscribers should be rejected in all cases.
57. Fraud Identifier: SMS Faking.
Definition
A fake SMS is originated from the international C7 Network and is terminated to a mobile
network. This is a specific case when SCCP or MAP addresses are manipulated. The
SCCP or MAP originator (for example: SMSC Global Title, or A_MSISDN) is wrong or is
taken from a valid originator.
Description
The delivery of a Mobile Terminated SM is in two parts:
A. The SMS-C uses the destination MSISDN to address a MAP message <Send
Routing Information for Short Message>, to the Home Location Register (HLR)
for that customer to find out whether the MSISDN is valid, can receive SMS, and
if so, to determine the current switch (MSC) that the destination user is registered
on. The HLR responds to the SMS-C with the information.
B. The SMS-C sends the actual text of the SM to the currently registered MSC and a
MAP message <Forward Short Message>. The MSC responds to confirm the
message was delivered, and generates a CDR containing all relevant information
including the SMS-C address.
In the faking case, the first part is done exactly as described above. However, the second
part is changed so that the source address in the MAP message <Forward Short
Message> is changed, often to someone elses SMS-C address. The manipulation of the
SMS-C address causes any inter-PLMN SM accounting to be in error, and means that
any policing against the apparent Spam generator harms innocent parties and is
ineffective against the real Spam generator.
The faking of the source address in the SCCP called party Global Title and the Service
Centre Address in the MAP message <Forward Short Message> whilst having the
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 56 of 66
correct equivalent address in the MAP message <Send Routing Information for Short
Message> is impossible without considerable efforts by the technical staff running the
SMS-C. In other words, it does not happen either by accident, faulty configuration data or
as the result of raw text messages received from the Internet. It happens because in most
cases it requires a software patch on the SMS-C. Therefore; any instances of this
happening are as the result of direct action by SMS-C staff, and probably in conjunction
with assistance from the staff of the Associated PLMN.
58. Fraud Identifier: SMS Global Title Scanning
Definition
A Global Title is an address used in the SCCP protocol for routing signaling messages on
telecommunications networks. In theory, a global title is a unique address which refers to
only one destination, though in practice destinations can change over time. The Global
Title Scanning is the fact to send SMS MO to all Global Title address from one mobile
operator in order to find unsecured SMS-C (SMS-C that are not controlling the A
number).
Description
The Technical Aspect of Global Title Scanning is:
Multiple SMS Forward SM Submits are received, generally, from the same mobile
MSISDN with the Called SCCP Address and Service Centre Address
incremented on each attempt. It would appear that individuals using a mobile with
a computer connection are instigating these scans.
The easiest of these scans to spot are sequential in nature scanning 10,000 GT
at a time. It has also been seen randomized scans, though on sorting the data it is
clear that blocks are being scanned.
This type of messaging is picked up in normal statistics in monitoring expected
and unexpected combinations of direction, GT and message type.
There can be no valid reason for such scanning of networks other than locating
unsecured SMSC. With simpler computer integration with mobiles and SMS
emulation software readily available this type of activity is likely only to increase. It
would be desirable for such activities to be reported to the Home PLMN of the
originating MSISDN in order to have the service removed.

59. Fraud Identifier: SMS Open SMSC
Definition
Open SMSCs are SMSCs that do not validate the sending subscriber that attempts to
use them to deliver messages. Generally each operator configures their SMSC to reject
messages from subscribers other than their own.
Description
Fraudsters may first attempt to locate open SMSCs by performing GT Scanning (also
called SMSC sniffing), where multiple MO messages are sent trying to find an unsecured
SMSCs. When the fraudster locates an open SMSC and then sends an MO message by
changing the SMSC address on their device, it will travel to this open SMSC and be
delivered via it.
60. Fraud Identifier: Pre-paid PIN Theft
Definition
Any activity which allows use of an active PIN without paying the legitimate amount is PIN
theft. This can be recharging of the services by the end user or retailing and distribution
by the sales houses without paying the legitimate amount.
Description
PIN generation process is a much secured process and the systems involved are
absolutely non-intrusive. The process involves generation of PINs, distribution of newly
generated active PINs for voucher printing and finally selling the printed vouchers with
active PINs through the chain of distributors and retailers to end users. The entire
process is very vulnerable to theft. Active PINs can be stolen and used even before
printing of the vouchers or can also be stolen during the voucher printing causing end
user to suffer who has paid the legitimate amount only to get used PIN. PIN theft can be
as simple as smart thieves look over the shoulder of original buyer while he is trying to
recharge and use the PIN even before he is able to recharge.
PIN theft can be an isolated incident of stealing PIN number from an original buyer or can
be an organized crime of stealing active PINs involving someone from PIN generation
team or from vendors involved in voucher printing.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 58 of 66
61. Fraud Identifier: Pre-paid PIN Guessing
Definition
PIN guessing is essentially an act of guessing the PIN by trial and error, intelligence or by
use technology either with partial information about PIN or its generation process.
Description
Knowledge about the PIN generation process or PIN as such lead to incidents of PIN
guessing. In this case a fraudster with partial information about an active PIN may guess
the remaining numbers and use the PIN before legitimate buyer can use it. These
incidents can be isolated done by a novice, can be an act of organized crime where
someone has leaked the information about PIN generation algorithm or an act of software
hackers who may not be interested in making money but would break the system out of
curiosity causing damage to the operators.
62. Fraud Identifier: Pre-paid Stolen Voucher
Definition
This is specific case of PIN theft where printed vouchers with active PIN are stolen from
anywhere in chain after voucher printing. It can be from printing press, distributors, and
retailers or from the consumers.
Description
This is an act of direct stealing, where printed vouchers with active PIN get stolen either
from the consumer or in the distribution chain. Thief in this case may use the voucher for
subscribing to the services himself or resell it at same or lower cost to make money out of
it. This can be an isolated incident where a thief steals voucher from retailer or consumer
or it can be an organized crime where entire lot/series of voucher gets stolen from
warehouse or from distributors.
63. Fraud Identifier: Pre-paid Altering Free Call Lists
Definition
In this case user is allowed to make calls without being charged for it. This can be done
by intruding the system with false information.
Description
There is a list which contains all MSISDNs/Phone numbers which are allowed to make
free calls. These are usually numbers of staff, government personals and VVIPs to which
operator has given this facility. Now someone who has/gets access to this list can alter it
by adding self/family/friends phone number to the list thereby allowing them to make free
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 59 of 66
calls. As evident in the description this cannot be done without help of someone part of
the operator who can get access to this list.
64. Fraud Identifier: Pre-paid Manual Recharges
Definition
Act of manually giving credit to a subscriber without any legitimate case for the subscriber
to get manual credit.
Description
There is a process by which customers are given manual credits with legitimate cases
coming from customer care, customer grievance redressal cell, loyalty management
systems etc. This is manually done by editing the account balance information of the
customer. This leaves a possibility of fraud where a person involved or someone getting
access to the system can manually grant credit to self/friends/family without a legitimate
case enabling them to abuse the services. This is a kind of internal fraud.
65. Fraud Identifier: Pre-paid Voucher Modification
Definition
Act of tampering the voucher by changing voucher denomination is voucher modification.
Description
Fraudsters modify the amount or duration or both denominated on vouchers to sell it at a
higher amount than stipulated amount. It is the end user who suffers by paying more or
not getting the requisite service, however this type of fraud impacts the reputation of the
service provider as well. Fraudsters usually attach service providers in a planned manner
by picking up the weak points in the vouchers. By the time it comes to the notice of the
service provider this incurs huge loss in terms of customer grievances and dissatisfaction.
66. Fraud Identifier: Pre-paid Duplicate Voucher Printing
Definition
Act of duplicating the vouchers with same PIN while printing with an intention of making
more money is duplicate voucher printing fraud.
Description
Enterprise partners or someone internal is responsible for allowing/getting duplicate
vouchers printed with same PIN on it. These vouchers are then sold in the market
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 60 of 66
through different channels. The user who consumes the PIN first gets the service and
rest all suffer loss. This is an organized crime with involvement of staff or people from
wholesale partners. Customers complain are often isolated and by the time fraud gets
identified fraudster have already made huge money and escaped.
67. Fraud Identifier: Pre-paid Fraudulent Voucher Reading
Definition
Act of using technology to smartly read the PIN information from a voucher without the
knowledge of the user who has bought the voucher.
Description
Fraudster indulge in this activity use smart devices from magnifying glass to card readers
to cameras to read PIN information while voucher is still in the pocket or wallet or while
someone is trying to recharge. This is mostly an act of an individual who mostly tries to
benefit himself or sell the stolen PIN to make money. They keep on inventing/learning
new techniques to read the voucher information. This type of fraud mostly prevalent with
credit cards and from there also has started impacting the prepaid vouchers.
68. Fraud Identifier: Pre-paid Illegal Credit Card Use for Recharges
Definition
Act of using a credit card to pay for recharges without the authorization of the legitimate
card owner. The user fraudulently impersonates the genuine account holder.
Description
Stolen credit card data, account numbers and expiry dates are readily obtained by
corruption of hotel staff, restaurants, banks and almost anywhere cards are used. Stolen
cards are easily used at point of sales having no on-line card verification. Even with on-
line card verification the card may be freely used until the theft is reported to the card
center and the card is blacklisted. Fraudsters make use of these gaps to recharge the
services and abuse it till the time it really reported, investigated and identified. Usually
before being identified or any action can be taken they use the amount and escape.
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 61 of 66
69. Fraud Identifier: Pre-paid IVR Abuse/Hacking
Definition
Acts of abusing the IVR in order to recharge more than one account using the same
voucher number, modifying the voucher status in order that it may be reused, and altering
the PIN value.
Description
IVR abuse/hacking can be both internal and external. Internally a staff can modify the
voucher status, its PIN value in the IVR system making it allowing for repeated recharge
from same voucher or higher amount recharge than legitimate amount. Externally IVR
system can be hacked to make changes in the voucher statuses or PIN recharge
amounts. IVR systems can also be attached with simultaneous calls making it break or
perform abruptly.. Hackers and technology enthusiast are often involved in these
activities and take proud in breaking the established systems. Intention may or may not
be to make money.
70. Fraud Identifier: Pre-Paid IN Flag Modifications
Definition
Tampering the IN flags with an intention to abuse or benefit self/family/friends is IN flag
modification fraud.
Description
All HLRs has a IN flag for services and rates to which any pre-paid subscriber the
legitimately subscribed to. Charging from customer account happens based on these
flags. Someone internal with an intension to abuse or benefit someone may temper with
these flags. The impacted subscriber will continue to suffer the loss unless it comes to
notice and then notified with the service operator and in case of someone getting
benefited it remains unnoticed unless it is caught by some intelligent tool or during profile
reconciliation or analysis.
Manual removal of the IN flag manually on the HLR or using a billing system specific
command. Staff in collusion possibly in collusion with third parties, decide to remove
prepaid flags to provide family, friends or criminals (supporting call selling operations) free
prepaid calls.

71. Fraud Identifier: Pre-paid Handset Manipulation
Definition
The manipulation of a handset to obtain information in engineering mode or to create an
additional identity duplicating the original and the subsequent use of services provisioned
to the original.
Description
Modifying the handset information like IMEI numbers or clone it so that it gets undetected
and then using it for illegal purposes. Fraudsters set up and advertise a call selling
service and route these calls through fraudulently obtained, cloned, or stolen handsets
increasing the revenue share before network detection.
Fraudster configures false base station to look like the network they intend to attack.
Network parameter/settings can be obtained from simple analysis of the surrounding
base stations using test equipment or a handset in engineering mode.
72. Fraud Identifier: Pre-paid Handset Installment
Definition
Act of not paying the installment for handset either by escaping or reporting loss of the
handset and later selling the handset or manipulating it for other purposes.
Description
Buying a handset on installment and not paying the installment either reporting loss of
handset or escaping. Main intention behind this fraud is to sell the handset and make
money or indulge in a bigger crime by manipulating the handset. This is a rare case of
fraud in pre-paid services as handsets on installment are now not usually offered with
prepaid services.
73. Fraud Identifier: Pre-paid Roaming
Definition
Act of making use of gaps of delays in accounting while roaming to use services with
intension of not paying
Description
With the advancement of technology this no more exists, however roaming fraud still
prevalent in case of post paid subscription. The basis lies in the fact that there is delay in
getting the call/usage information from roaming partners. Fraudsters indulge in this kind
Fraud Management Classification Guide
GB954, Version 2.2 © TM Forum 2013. All Rights Reserved. Page 63 of 66
of frauds take benefit of this gap and then escape. By the time service provider gets to
know about the usage it is already late. Nowadays, technology has completely prevented
this fraud in case of pre-paid subscription and also to a large extent it has been prevented
in postpaid as well with use of NRTRDE.
