How many more data dumps does this hacker have with him that has yet to be exposed? Well, no one knows the answer, but we were recently made aware of another data breach – the same Russian hacker who was behind the massive breaches in some of the most popular social media sites including LinkedIn, MySpace, Tumblr, and VK.com.

The hacker is now selling over 51 Million records obtained from iMesh – now defunct peer-to-peer file sharing service.The New York-based iMesh was one of the first and most popular file sharing services that allowed users to share multimedia files with their friends via the peer-to-peer protocol.
