At the point of capturing application details, ensure that the application matches with the identity documents provided by the customer. Triangulate the details with publicly available data sources and identity issuing authorities to verify that the customer is not deliberately providing inaccurate or fabricated information.
A. PRISM is a database of over 3 million International Revenue Share test numbers (IRSF), as at 20 March 2020, which are provided by IPRN resellers to test that a revenue share destination and number range can be called from a given location. These test numbers, used as a hotlist, can be a valuable tool to alert CSP’s of a pending or live IRSF attack.
See how Prism IRSF database would have prevented a massive attack on a small MVNO that led to its liquidation. This is not fear mongering. Instead, this study, like a flu virus, carries a simple message that International Revenue Share Fraud (IRSF) is real and action should be taken now. IRSF continues to top the fraud types reported by global telecom providers (CFCA Global Fraud Loss Survey 2019). Whether you are small, big, MNO, an MVNO, a fixed or VoIP operator, lack of a sound Fraud Management Strategy and a Fraud Monitoring System that supports a hotlist of IRSF numbers, will be an easy target for fraudsters. And like this MVNO, the consequences could be devastating.
