The 10 Biggest Security Stories Of 2011


Security firm HBGary, which had publicly declared war on the hacker group Anonymous, reported in February that the infamous group had defaced HBGary's homepage and stole 60,000 corporate e-mails and posted them to Pirate Bay, a Swedish site that lets millions of people share multimedia, computer games and software via BitTorrent. Anonymous also hacked the Twitter account and LinkedIn profile of Aaron Barr, chief executive of HBGary Federal, the subsidiary of HBGary that had been working to uncover the identities of the actors behind Anonymous. The company had been boisterous in its campaign to unmask Anonymous. HBGary had reportedly been preparing to turn information over to the FBI, which was investigating attacks on PayPal and Amazon. The companies had become targets of Anonymous after they cut ties with whistleblower site WikiLeaks.
