Attackers have invaded corporate networks to steal sensitive data and use them as staging grounds to attack other corporate networks — and IT managers detecting these invaders may find yet another surprise: law enforcement lurking in their networks monitoring it all as part of a cyber-sting. “There may be law enforcement watching it,” said Charles Shugg, retired Brigadier General of the Air Force who once headed the U.S. Air Force Cyber Command, and spoke yesterday on a panel at the RSA Conference on the topic of how far IT managers can go to “hackback” against network attackers they happen to detect. But you might be stepping into something bigger than you know, because “an undercover agent may witness crimes taking place and not stop them in hopes of getting them,” said Shugg. It’s just another wrinkle in the world of cybercrime that’s invaded corporate networks, whether it be suspected Chinese spies stealing important intellectual property, remotely-controlled botnets and cybercooks from everywhere making off with what they can, or hacktivists out to score political points.
