RansomHouse Claims Trellix Cybersecurity Firm Breach
Data exposed:
  • source-code
  • internal-dashboards

Ransomware group RansomHouse has claimed responsibility for a breach of Trellix, the cybersecurity company formerly known as McAfee Enterprise and FireEye, gaining access to portions of its source code repository and internal management dashboards.

Public reporting indicates that Trellix disclosed the incident, confirming that unauthorized actors accessed a portion of its source code repository. The company stated it found no evidence that the breach impacted its release or distribution processes. RansomHouse published screenshots of internal dashboards as proof of the intrusion. Available reporting describes the exposed material as including source code and access to internal services, though the precise number of individuals affected remains unknown. Industry research from sources such as DoxxScan™ continuous monitoring indicates that credential-related exposures in enterprise breaches frequently surface in subsequent leaks on dark web forums.
