Trellix did not disclose the exact nature of the data that may have been accessed, but it indicated there are indications that its source code has been affected or exploited.

It added that, based on its investigation to date, there is no evidence that its source code release or distribution process was affected, or that the source code itself was exploited.

Trellix is owned by Symphony Technology Group and was founded in January 2022 after the merger of McAfee Enterprise and FireEye, with Mandiant later acquired by Google in a deal worth $5.4 billion. The Hacker News has reached out for comment and will update the story if a response is received.
