FireEye Breach

Speak With A Security Expert Now

THE THREAT (Executive Summary):

On December 8th, FireEye disclosed that they were the victim of a nation-state attack. During their investigation, they discovered that an attacker targeted and accessed certain Red Team assessment tools FireEye used to test their customers’ security. These tools mimic the behavior of known cyber threat actors and fortunately, this disclosure did not include tools to exploit zero-day vulnerabilities or unknown techniques.

FireEye has developed and publicly released approximately 300 countermeasures, aimed at arming the security community at large to defend against the attacks they authored. eSentire has implemented new detection content based on information shared by FireEye. We will continue to monitor the situation and deploy new detection content as necessary.
