Toll fraud is nothing new. Pretty much since there have been telephones, or at least enterprise telephone systems, attackers have sought to somehow hijack or piggyback on them in order to place toll phone calls at the expense of the company that owns the phone system. As with many other types of ‘cyber crime’, the crime itself is not new, but technology often makes it easier and faster than the more traditional version of the crime.
Mark Collier, CTO of SecureLogix and co-author of Hacking Exposed: VoIP, noted in a recent blog post what a threat VoIP toll fraud is. Collier points out that, while there may be a variety of ways to attack a VoIP system, toll fraud is one of the few with a clear and direct motive. Collier refers to a white paper detailing a recent toll fraud VoIP breach in Germany, and also alludes to a similar situation here in the United States that resulted in $250,000 of toll fraud theft. You can get more details on these incidents and VoIP toll fraud in general by checking out this post on Collier’s blog.
