FBI: Criminals auto-dialing with hacked VoIP systems

Criminals are taking advantage of a bug in the Asterisk Internet telephony system that lets them pump out thousands of scam phone calls in an hour, the U.S. Federal Bureau of Investigation warned Friday.

The FBI didn't say which versions of Asterisk were vulnerable to the bug, but it advised users to upgrade to the latest version of the software. Asterisk is an open-source product that lets users turn a Linux computer into a VoIP (Voice over Internet Protocol) telephone exchange.

In so-called vishing attacks, scammers usually use a VoIP system to set up a phony call center and then use phishing e-mails to trick victims into calling the center. Once there, they are prompted to give private information. But in the scam described by the FBI, they apparently are taking over legitimate Asterisk systems in order to directly dial victims.
