Aaron Barr was the CEO of HBGary who instigated and oversaw the contracting firm's disastrous attempt to infiltrate Anonymous, which resulted in Anonymous hacking their servers and publishing over 70,000 emails - thereby revealing the Team Themis conspiracy. Prior to HBGary, he was Technical Director at Northrop Grumman Information Systems, Chief Engineer at Northrop Grumman Corporation, Technical Director at Northrop Grumman Information Technology, Program Manager at Northrop Grumman Information Technology and a Petty Officer 1st Class in the U.S. Navy.
Barr has an interest in Persona Management, having bid on the 2010 USAF contract to produce custom software for use by CENTCOM and having also produced a short treatise on the subject] for Mantech, which had an interest in using the capability in conjunction with software produced by Palantir. Towards the end of his tenure at HBGary, Barr entertained an offer by Mantech to serve as an executive of a newly-formed subsidiary of that firm.
On 28 February 2011, Barr resigned from HBGary Federal to "focus on taking care of my family and rebuilding my reputation." This came after widespread media coverage of Barr's central role in Team Themis.
By September, Barr was nonetheless making the case that the security industry has not been sufficiently unleashed upon the world at large. For reasons why this may not be a particularly strong argument, please see every single thing on this wiki.
