Hackers Compromise Accounts of FireEye Threat Intelligence Analyst

A hacker or group of hackers claimed today to have breached FireEye's Mandiant. In a Pastebin post, they claimed, "It was fun to be inside a giant company named 'Mandiant'... 'Mandiant' knows how deep we breached into its infrastructure." The "proof" of the breach was somewhat limited information about one Mandiant/FireEye employee, Adi Peretz (FireEye purchased Mandiant for $1 billion in January 2014). Peretz is described in the Pastebin post as 'Victim #1', a 'Senior Threat Intelligence Analyst at Mandiant.' There is no evidence of a breach deep into Mandiant's infrastructure, and a FireEye spokesperson told SecurityWeek that the company network has not been breached.
