Recently Discovered Vulnerability in NEC Phone Systems Leaves Thousands Vulnerable to Toll Fraud

Our telecommunications engineers have recently discovered a security vulnerability in the popular NEC SL1100 phone systems that can be exploited for toll fraud. Commonly known as “phreaking,” Toll fraud is the practice of exploiting vulnerabilities in phone systems and is quite possibly the oldest form of hacking. To this day, phreaking accounts for more monetary damage than credit card fraud. Once a hacker has compromised your phone system, they are virtually undetectable and capable of routing calls – including international calls –  through your system and sticking you with the bill.

All phone systems, just like computer systems, networks, and mobile devices, are susceptible to security vulnerabilities. Manufacturers like NEC put tremendous effort behind securing their systems, but no system can be made completely secure. Security requires constant vigilance, particularly in today’s connected world.
