Growing need for a stronger front against fraud

Operators have limited intelligence on global fraud trends, and are hence inadequately prepared to deal with fraud incidents. Lack of cross-border jurisdiction means that even if fraud is detected, fraudsters can simply move to a new country and start all over again.

Fraud is complex and so is detection, with operators having to scan for multiple means of committing fraud (roaming, theft, subscription, hacking and many more). Criminals operate round the clock – for operators, maintaining a 24 x 7 fraud ops team is expensive and often not feasible.

European Operator Case-Study

A Tier 1 European operator wanted to protect its network and customers from growing levels of telecom voice fraud.

It experienced growing levels of fraud committed by outbound & inbound roamers. Roaming is the biggest enabler for the most prevalent types of mobile telecom fraud – International Revenue Share fraud and Premium Rate Service fraud

PBX hacking fraud incidents had increased sharply. To perpetrate this fraud scam, fraudsters hacked into enterprise PBX systems. They then placed many calls as possible to international premium rate numbers or other international expensive destinations that they owned or where they intended to receive a share of the revenue generated.
