A security expert at a managed services provider has kicked off a project to expose and blacklist the networks hosting VoIP attacks against his and other companies' VoIP PBX servers. The VoIP Abuse Project uses a honeypot to gather as much data as it can from incoming VoIP attacks, including the IP address and a recording of what the call was sending.
Some operators of the offending networks are unaware that their VoIP systems have been hacked and are being used to place fraudulent calls. The attacks range from brute-force hacking to acquire usernames and passwords of the VoIP systems to callers posing as a customer's bank in order to convince victims to hand over their bank account numbers.

J. Oquendo, the security engineer who built the so-called Arkeos VoIP honeypot that runs the VoIP Abuse Project, says he decided to launch the VoIP abuse project because he was tired of seeing brute-force attempts against VoIP PBXes and having to contact the organizations whose networks were being used in the attacks -- only to often be ignored. He also wanted to make other companies with VoIP PBX servers on the Internet aware of the threat and actual attacks out there so they could block them.
