Cybersecurity company Trellix has announced β that it suffered a breach that enabled unauthorized access to a "portion" of its source code.
It said it "recently identified" the compromise of its source code repository and that it began working with "leading forensic experts" to resolve the matter immediately. It also said it has notified law enforcement of the matter.
Trellix did not disclose the exact nature of the data that may have been accessed by the attackers. However, it pointed out that there are no indications that its source code has been affected or exploited.
The company did not share any details about who may be behind the incident, and for how long the attackers had access to its systems. Trellix noted that additional information will be shared as appropriate once its investigation is complete.
Owned by Symphony Technology Group, Trellix was founded β in January 2022 following the merger of McAfee Enterprise and FireEye. Around the same time, Mandiant, which was owned by FireEye, was acquired by Google in a deal worth $5.4 billion.
The Hacker News has reached out to Trellix for comment, and we will update the story if we hear back.
