Telefonica Wants to Solve Multibillion Dollar Fraud Market

Telecom fraud is a fast-growing field of criminal activity and a low-risk alternative to traditional methods of financial crime, costing today’s world some $32.7 billion annually, according to a joint report published in March by Europol’s European Cybercrime Centre and Trend Micro, a Taiwanese cyber security and defense company.

“Telecommunications fraud is another example of criminals ‘hacking the system’ in order to abuse legitimate enterprises for criminal gain,” said Steven Wilson, Head of the European Cybercrime Centre.

Telefonica wants to solve this problem.

Their solution consists of 2 modules: TUKU IN, which covers the detection of fraud on the Incoming traffic streams: Bypass (including Bypass OTT and Bypass Roaming), Hijacking, False Answer Supervision and manipulated CLI; and TUKU OUT, which focuses on the prevention and detection of anomalous traffic in Outgoing traffic streams, providing automatic blocking linked to alarms of potential International Revenue Share Fraud (IRSF), detection of Wangiri, and also includes a Fraud Management System (FMS).

TUKU Web is a multiplatform tool which does not require installation. TIWS manages the service end-to-end to prevent, detect and avoid fraud in order to limit the economic consequences of the fraudulent activity, taking action to stop payment flows to the instigators of fraudulent traffic.

The role of wholesalers in fraud prevention must evolve above and beyond simply identifying existing fraud patterns and black listing numbers. Fraudsters are continually finding new ways to defraud, so it is critical for wholesalers to not just transport traffic, but to know what is being carried and have the right tools in place to tackle potential fraud. TIWS is fighting fraud at all stages: Prevention, Detection and Action.

TUKU Web, developed by TIWS, detects not only existing patterns, but also new fraud patterns thanks to using up-to-date fraud detection software and processes, including system updates to combat new fraud schemes as they become known. As a proprietary solution, it can also be adapted and enhanced to adjust to customers’ future needs providing reassurance that safeguards will not become out of date.

TIWS’ experience as the international carrier for the Telefónica Group, operating in many different domestic markets under multiple trade and regulatory schemes, means it has been challenged by all kinds of fraud patterns itself, making it well placed to be an antifraud service provider to help other carriers tackle fraud.

Juan Carlos Bernal, CEO of Telefónica’s International Wholesale Business Unit explains “We continuously strive to be the best partner we can be for our clients and adding state-of-the-art fraud prevention to our services makes us an even more reliable, responsible and trustworthy international partner. We are privileged to be able to share our experience to help our customers fight fraud.”
