Toll Fraud

Toll Fraud in context

Telecom fraud costs operators an estimated $40+ billion per year. Common vectors include International Revenue Share Fraud (IRSF), Wangiri callback scams, SIM box bypass, PBX hacking, subscription fraud and A2P grey routing. Effective defense combines real-time signaling analytics with CDR-side machine learning.

Telecom networks depend on Internet-style routing (BGP, DNS, MPLS) for interconnect, transport and application delivery. Route hijacks and DNS abuse can degrade or intercept signaling as easily as any application-layer attack, which is why RPKI and DNSSEC are now standard hardening for carrier networks.

To place Toll Fraud in the wider telecom-security picture, review Traffic Pumping, OTT Bypass, BGCF, PBX Hacking, PBX Dial-Through Fraud and SIM Box.
