Introduction
Telecommunications fraud, often known as telco or telecom fraud, is any behavior that uses deceit to exploit and gain an advantage over telecommunications providers (fraudulent practices).
This includes IRSF fraud (International Revenue Sharing Fraud), in which criminals take advantage of premium phone rates and interconnect bypass fraud, a call rate arbitrage between operators. Telecom fraud prevention is the need of the hour amid many frauds in the telecom sector.
Outline
In this blog, we will discuss 11 types of telecom fraud worldwide. Each copy will be covered in detail. We will also talk about telecom fraud prevention and detection and its outcomes.
What Is the Process of Telecommunications Fraud?
Because telephony is the world's biggest and oldest deployed network, accounting for 48% of global consumer electronics sales, fraudsters have long developed methods and procedures to exploit it.
And, unlike other fraud assaults, which change swiftly as firms crush them, telecom fraud is distinct in that it is often taken for granted. Its expenses are borne by operators who avoid integrating complicated risk management systems into their designs.
To make matters more difficult, telecom firms also break down their services to resell them to local networks and carriers - a £4/$5 billion market in the UK alone. As the technology to create your mobile network becomes more readily accessible, huge telecom providers are becoming indirect targets of fraud, making it more difficult to detect.
Telecommunications Fraud Comes in 11 Forms
Let's look at the most typical telecom fraud attacks that operators should be aware of for prevention.
International Revenue Sharing Fraud (IRSF)
IRSF fraud, or international revenue sharing fraud, takes advantage of premium phone rates, which are then phoned unknowingly by consumers.
It is the most significant fraud risk for telecom carriers, costing the industry between $4 and $6.1 billion annually.
Here's how it works:
Bad agents register to rent a premium phone number.
They get access to a company's phone system and dial that number.
The company pays up to $1 each minute, with 25% of the money going to the fraudster.
Businesses may find themselves with excessive phone bills for calls they did not make.
The calls are often made outside of business hours, and firms are only made aware of them when it comes time to pay the bill.
Interconnection Fraud
To make cheaper phone calls, interconnect bypass fraud, also known as SIM box fraud, takes advantage of a termination rate. Telecom providers are anticipated to lose $2.7 billion in revenue annually. To better comprehend it, consider the following situation involving two operators from different countries:
A client of Operator A dials a number for a customer of Operator B.
Operator A charges a fee per minute to its customers.
Operator B costs Operator A for making the call to its client.
The termination rate is the fee at the end of the call. These fees vary dramatically based on the contracts between the two operators. Some are pricey, while others are close to nothing.
This is when a shady operator enters the picture. They redirect international calls via a SIM box or GSM gateway, thus hijacking the connection to get lower termination fees. They effectively make long-distance calls significantly cheaper, but the caller pays the same amount - thus, the swindler telecom keeps the difference.
Telecommunications Arbitrage Fraud
Arbitrage is the technique of profiting from price disparities. In telecommunications, these disparities may be seen in long-distance pricing across nations. As with international bypass fraud, it may reduce international client costs while allowing unscrupulous organizations to insert themselves between operators. They promise to link directly from nation A to country B, but the connection is routed via a lower-cost country.
PBX Infiltration
PBX hacking enables criminals to gain control of phone lines by exploiting vulnerable phone networks. A private branch exchange (PBX) is a phone network that links to other networks. For example, it enables businesses to share lines and decrease the number required in an office. Because many of these PBXs are IP-based, hackers may easily exploit them.
They will get access to the system and utilize it to their advantage, such as in the cases of IRSF fraud stated above. This cybersecurity and information technology vulnerability can be prevented by improving internal controls and password security.
Increased Traffic
Traffic pumping, commonly known as access stimulation, is a technique in which unscrupulous local exchanges manipulate the number of calls to their networks to gain from FCC compensation payments. The Telecommunications Act of 1996 requires giant telcos such as Verizon, Sprint, and AT&T to pay fees to rural carriers. Therefore these carriers make every effort to increase the number of calls to get more outstanding payments.
Deposit Theft
Like credit card theft, deposit fraud targets telecom carriers' online storefronts with stolen credit card details. Fraudsters often buy prepaid SIM cards, although the same practice may be used with gadgets (routers, smartphones, etc.).
The issue, of course, is that online telecom businesses must reimburse the costs in the form of chargebacks. You could, of course, depend on your payment processor to lower these rates or employ chargeback-guarantee telecom fraud prevention systems. However, doing so exposes your organization to high rates of false positives — where real consumers are prohibited from completing a transaction.
Subscription Fraud
Criminals sign up for contracts in the telecommunications industry using stolen credit cards and stolen ID information. Phone contracts are more difficult for fraudsters to get than things since they need a kind of KYC verification. Before a person may subscribe, their identification must be verified.
Fraudsters like high-end cell phones are obtained via contracts. It's as easy as presenting
forged identification, jailbreaking the smartphone, and reselling it on used marketplaces.
When the repossession business arrives, it learns the individual does not exist.
The takeover of an Account
Telecom firms that provide online user accounts may fall subject to ATO attacks, in which fraudsters get the login and password information of other users and sign on in their stead.
If your online shop allows people to establish accounts, fraudsters will likely steal them regardless of your offer. It is costly, as Javelin believes that recovering a user's account costs a firm an average of $263, not to mention the harm to your company's image.
You must have procedures to verify user logins to guarantee that only the proper individuals are allowed into your business.
SMS Phishing/Smishing
Smishing, also known as SMS phishing, is sending bulk SMS messages to gain personal information from recipients.
Customers and telecoms are both plagued by mass spam tactics. As a result, SMS phishing rings have gotten skilled at evading detection. They've been known to utilize software to ensure that the numbers they target are mobiles rather than landlines, to set up auto-shops to resale stolen information, and even to offer their hosting services to host phishing sites and marketplaces.
Wangari Fraud
Wangari telecommunications fraud, which translates as "one and cut," includes piquing clients' interest by contacting them, letting the phone ring once, and then hanging up. The client would often call back, unknowingly dialing a pricey premium line controlled by the scammers.
SIM Jacking and SIM Swapping
SIM jacking, also known as SIM swapping, occurs when fraudsters gain control of a person's phone calls and SMS messages by swapping a phone number for the one they control.
As more businesses, such as banks, employ OTP (one-time passwords) and 2FA (2-factor verification) supplied by text messages or phone calls, fraudsters seek to control people's phone numbers to intercept them.
SIM jacking or SIM switching is a kind of account takeover that they use. The fraudster will call the telco's customer care and request that their number be transferred to a new SIM they control. When the operation is over, they will be able to get all of the OTPs and SMS verifications required to hijack user accounts, ranging from social networking to finance applications.
What Is Detection and Prevention of Telecommunications Fraud?
Telecom fraud prevention and detection is a wide word encompassing any approach or plan to curb illegal activities meant to exploit telecom operators. Telecom fraud prevention and detection should concentrate on three critical areas:
Screening and eliminating unscrupulous resellers
Safeguarding corporate income by guaranteeing that users and customers are who they claim to be
Secgen can assist in the third area, owing partly to technologies such as device fingerprinting, data enrichment, and machine-learning recommendations.
Fraudsters are skilled at escaping detection. They will utilize stolen IDs, card numbers, and other methods available to conceal their true identities and goals. This is true whether your telecoms company interacts with a consumer from an internet shop or a local provider.
With Secgen, you can learn as much as possible about the person you're interacting with while causing the least friction. In telecom, fraud prevention implies developing frictionless, invisible, and efficient solutions to collect data without interfering with your telco company clients' customer experience.
Conclusion
Smoother company operations and lower rates of account takeover, ID fraud, and transaction fraud are possible owing to a robust machine-learning-driven engine and comprehensive risk management control.
