Wangiri 2.0 (Wangiri 2.0 (Web-Initiated Callback Fraud))

Wangiri 2.0 is an evolution of Wangiri callback fraud where victims are lured — via web forms, chat prompts, or app dark patterns — to submit their phone number, which is then called back from a premium-rate range in a way that traffic-pumps IRSF revenue. It moves the trigger from a physical missed call to a web-scale click-fraud attack surface.

Wangiri 2.0 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.

To place Wangiri 2.0 in the wider telecom-security picture, review Billing System, PBX Hacking, Revenue Share Fraud, Blue Team, BSS and Data Localization — each entry cross-references back to this page so you can walk the topic in either direction.
