Fraud Assurance Risk Areas
International Revenue Share Fraud
International Revenue Share Fraud (IRSF) costs businesses nearly five billion dollars each year. Fraudsters make money by generating bogus phone calls to international premium rate numbers you have paid for as a business.
Premium rate number services are a popular business model because they are so easy to use and simple to put in place. But it’s the simplicity which makes them a lucrative target for fraudsters. The caller is faced with a large bill for the unauthorised calls while the cheats collect a pay-out from the company that owns the premium rate number. They win You lose.
Top 5 International Revenue Share Fraud scams:
- Taking advantage of an unintended or misconfigured cheap calling rate to the terminating party, allowing the terminating party to collect more revenue than the originating party spends making the call.
- Making the call on someone else’s account. Typically using a stolen handset or hacked PBX.
- Tricking a normal subscriber into calling a revenue share number (E.g. Wangiri)
- Setting up a post-pay subscriber with no intention of ever paying the bill.
- Acquiring free airtime through stolen top-ups or internal fraud.
International & Domestic Bypass Fraud & SIM Box Activity
Bypass fraud is the deliberate routing of voice traffic for in-country termination to avoid international toll gateway interconnection points. Calls are diverted over alternate routes and placed on the terminating network at the cheapest call rate possible.
The presence of bypass prevents the destination network from collecting valid billable incoming international minutes. The bypass network (BPN) is established as an unlicensed operation, thus operating outside regulatory, legal, commercial and other government controls.
Bypass Fraud Types
- OTT Application – Originating subscriber calls an E164 number but the call is hijacked and terminated on an OTT application.
- Preferred Partner Refiling – Where a CLI is changed by one of the interconnect partners / fraudster to mislead the terminating network.
- Re-Originating Calling – Traditional MSC SIM box bypass. International call is hijacked and the final leg is terminated as a local call.
- Unsanctioned or Ghost Routing – Call passed to the terminating network via a misconfigured or unsanctioned route.
