Aaron Barr is back - and he wants more cybersecurity offensives

Barr is back in business. Aaron Barr, the former CEO of HBGary Federal, memorably had his corporate e-mail exposed to the world by Anonymous earlier this year after attempting to expose the group's "leadership." Based on our reporting, comedian Stephen Colbert memorably summed up the encounter: "To put this in hacker terms, Anonymous is a hornet's nest, and Barr said, 'I'm going to stick my penis in that thing.'"

Barr eventually resigned from HBGary Federal after weeks in the spotlight—and after revelations emerged that he helped form dubious plans to attack Wikileaks, fake documents, and identify critics of the US Chamber of Commerce using "link analysis" technology.

But he resurfaced a few months later as the director of cyber security for government contractor Sayres and Associates. This week, he dusted off an old presentation on "Social Media and Evolving Cyber Threats" and made one of his first public presentations after the HBGary Federal debacle. We stopped by Barr's presentation to find out whether the criticism of Barr's own desire to play "offense" in cyberspace had changed his perspective. It had not.
