Trellix Confirms Source Code Repository Breach, Investigates Unauthorized Access Cybersecurity firm Trellix disclosed a security breach involving unauthorized access to a portion of its source code repositories. The company detected the compromise "recently" and has since engaged leading forensic experts to investigate the incident, while also notifying law enforcement. Trellix stated that its investigation has found no evidence that the accessed source code was exploited or that its release and distribution processes were impacted. However, the company did not specify the exact data accessed, the duration of the breach, or the threat actors responsible. Additional details will be shared as the investigation progresses. Formed in January 2022 through the merger of McAfee Enterprise and FireEye, Trellix is owned by Symphony Technology Group. The breach follows Google’s $5.4 billion acquisition of Mandiant, which was previously part of FireEye, around the same time. The incident remains under active investigation.
