We have always been aware that while, as an industry, our Fraud and Risk Managers are performing risk reviews, and planning and sharing intelligence to try and stay one step ahead of the fraudsters, those we are planning strategies against (ie. the fraudsters), are doing the same to try and stay ahead of us.

Fraudsters know when a CSP has improved its prevention and detection techniques, and so will move on to an easier target. Eventually they will find it difficult to keep finding easier targets, so will be forced to change their operating methods to counter the defence mechanisms being implemented.

For years, committing International Revenue Share Fraud (IRSF) has been based on targeting destinations where the call termination rates are highest, to maximise the fraudster’s earnings. However, the industry generally has become a lot more effective at identifying inflated traffic to these high-paying destinations, and in most cases, IRSF to them can be detected early and blocked.Start editing the text…

This is causing fraudsters to re-think their strategy, and many are now directing their IRSF calls to destinations that have traditionally been considered low risk. Their view is obviously that it is now in their interest to focus on lower-paying destinations in the knowledge that the originating carrier will, in most cases, take longer to detect this activity. So these fraudsters will continue to make reasonable money.
