The cybersecurity company said the attack compromised its software tools used to test the defenses of its thousands of customers.

“I’ve concluded we are witnessing an attack by a nation with top-tier offensive capabilities,” Kevin Mandia, the chief executive at FireEye and a former Air Force officer, said in a blog post published Tuesday. “The attackers tailored their world-class capabilities specifically to target and attack FireEye.”

The company said the attacker also accessed some internal systems and primarily sought information about government clients. FireEye said it has seen no evidence so far that data belonging to its customers had been compromised from the primary systems used to store it.

FireEye declined to comment on who it believed was behind the breach of its hacking tools, which experts said could potentially be leveraged in future attacks against its customer base, including a diverse array of U.S. and Western national-security agencies and businesses.
