Around 10 pm last night, popular social networking site Twitter, was apparently hacked by a group calling themselves the Iranian Cyber Army. Iran and Twitter have had a rocky relationship since last summer when Iranian citizens spread the protests over Iranian elections to the popular web site. During that time, links circulated on Twitter that allowed users to participate in DoS (Denial of Service) attacks on Iranian government websites. Given the name adopted by Twitter's hackers, it may be no coincidence that the New York Times interview with a U.S. computer security expert in June 2009 described the Twitter DoS attacks as allowing Twitter users to "'become part of the cyber-army,' in Iran."
