RansomHouse Trellix Source Code Breach | MSSP Advisory

RansomHouse compromised Trellix source code repositories and leaked proof of the breach through sample images. The security vendor confirmed unauthorized access to their development environment but claims no customer data or production systems were affected. RansomHouse typically targets corporate networks for data theft rather than deploying ransomware.

Your clients running Trellix endpoint protection, email security, or network detection tools now face potential zero-day exploitation if attackers reverse-engineer the leaked source code. Your own security stack is exposed if you deploy any Trellix products for client monitoring or your internal defenses, creating a direct pathway into your RMM and PSA environments through compromised security tools.
