Hacker collective Anonymous says it has taken revenge on a security firm whose principal claimed to have infiltrated the group. Hacker collective hacked Twitter account of CEO Aaron Barr, chief executive of HBGary. Barr’s social security number and address allegedly leaked in revenge for infiltration of hacking collective Anonymous. Anonymous claims to have deleted entire terabyte of data from HBGary’s backup server. HBGary site had been replaced by a placeholder this morning; Anonymous replaced front page with image rebuking the company’s site.
