HBGary is a computer security company that does penetration testing, intrusion detection and worm detection, quarantine, and analysis. They present themselves as experts in the computer security field, but recently they were successfully compromised by basic well known techniques.
Aaron Barr was conducting what he called "just research" on information gathering through social media. He would use Facebook, Twitter, Lindedin, and other social networks to gather data about his target and their family and friends. He claims he could find his target's real name as well as where they were from just from publicly available information on social media sites.
He decided that he wanted to go after what he saw as "the leaders" of Anonymous. This did not turn out well for Mr. Barr. He claimed to have found the real names of these so called leaders of Anonymous and was in talks with the FBI to gain a contract between them and HBGary Federal, that's right Aaron Barr was the CEO of HBGary Federal. HBGary Federal is a branch of HBGary that was to handle all federal contracts, but was falling short of it's goal and running out of money. This made Barr anxious to close a deal by any means neccessary.
