International Revenue Share Fraud (IRSF Model)

Also known as: RSF, IPRN fraud

Revenue share fraud is a class of fraud in which attackers artificially inflate traffic to number ranges (International Premium Rate Numbers, artificially inflated destinations) where they receive a share of the termination fee from a complicit number-range provider. Techniques include PBX hacking, malware-driven dialers, Wangiri callbacks and SMS pumping to OTP flows. Loss detection relies on destination hot-lists, velocity thresholds and interconnect settlement analysis.

Revenue Share Fraud in context

The radio access network is where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations and downgrade attacks; defenses rest on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

Telecom fraud costs operators an estimated $40+ billion per year. Common vectors include IRSF, Wangiri callback scams, SIM box bypass, PBX hacking and A2P grey routing.
