FireEye Breached: Taking Action and Staying Protected

To Our Customers, Prospects, Partners, and the Cybersecurity Community:

It’s not every day we see a fellow cybersecurity company, especially one with a significant presence serving the federal government, as the subject of a breach. On December 8, FireEye disclosed a sophisticated attack which led to the “unauthorized access of their red team tools.” The statement went on to say the company does not know whether the attacker intends to use the stolen tools themselves or publicly disclose them.

We are sad to hear the news; all cybersecurity vendors at some level share a unified purpose of making the world a more secure place. Our thoughts are with our colleagues at FireEye and with their customers. SentinelOne’s commitment to keep customers protected remains unwavering. We innovate to raise the cybersecurity bar to defend our digital way of life.

In this blog, we update on the actions SentinelOne has taken across our SentinelLabs security research team, Vigilance MDR team, and product team in response to the FireEye breach. Our platform is able to detect the known malware samples associated with the FireEye breach. 

Detection is Foundational to Visibility & Protection

We continue to monitor and hunt for relevant IOCs and artifacts related to the breach. We can also confirm that all assets that are seen so far in the wild are detected by the SentinelOne agents, with no upgrade needed. If there are parts of your network that are not protected with SentinelOne, we encourage you to close that gap, even if you need to exceed the number of licenses you have at the moment. We recommend the use of our Rogue system detection to identify the systems that should have an agent deployed. Below this blog, please find a list of hashes based on FireEye’s reporting and our own research that we confirm are covered.

Hunting Pack Released for Every SentinelOne Customer

We’ve already released a bespoke and ready-to-use hunting pack in every customer’s SentinelOne console for retrospective hunting missions. SentinelOne’s industry-leading data retention periods enable lengthy lookbacks for thorough investigations. This customized hunting package enables our customers to know if any of the artifacts related to this breach exist – or have existed – within your enterprise.

We’re Here to Help

SentinelOne is committed to doing the right thing – and we stand by ready to help at no cost. Here are several actionable steps our team suggests:
