US cybersecurity firm FireEye says it was hacked by a nation
US cybersecurity firm FireEye said it was recently hit by a "state-sponsored attack" carried out by a "highly sophisticated threat actor". FireEye CEO Kevin Mandia concluded the attack was done by "a nation with top-tier offensive capabilities". The attack is being looked into by the Federal Bureau of Investigation (FBI) and Microsoft, whose initial analysis has supported FireEye's conclusion.
