A previously unknown hacking group believed to be based in Iran has started cyber attacks inside the U.S., according to Mandiant Corp., a security company that’s linked China’s army to similar activity.
 
The Iranian group emerged within the last six months and has infiltrated the networks of at least one U.S. corporation, Richard Bejtlich, Mandiant’s chief security officer, said in an interview in Washington today.
