FireEye Breach Update

2 minutes read
Speak With A Security Expert Now

As an update from our Wednesday, December 9th, 2020 advisory, eSentire is continuing to closely monitor the situation. eSentire has not observed any indicators of compromise associated with the disclosure of FireEye’s Red Team assessment tools being used maliciously. We have detected numerous routine penetration testing instances using these tools and have alerted appropriately. MVS has been updated to include coverage for all CVE targets identified by FireEye (see below) and we recommend that you continue to review your reports and remediate associated vulnerabilities. We will continue to keep you updated if there are any additional updates. We encourage you to watch the recorded webinar that discusses this topic.

THE THREAT:

On December 14th, FireEye disclosed a global supply chain intrusion campaign based on compromised SolarWinds Orion releases. The compromised releases subsequently masqueraded its traffic as the Orion Improvement Protocol, thereby blending in with legitimate SolarWinds activity to obfuscate the threat actors' activities.

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.
