FBI FLASH warns of Kwampirs supply-chain intrusions
The FBI issued a FLASH alert about the Kwampirs remote-access Trojan targeting supply-chain and healthcare networks, urging organizations to hunt for indicators, tighten remote access, and segment critical systems.
Executive briefing: The FBI released FLASH Alert MU-000122-TT on describing ongoing Kwampirs (Orangeworm) intrusions against healthcare, industrial control, and software supply-chain targets. The remote-access Trojan leverages SMB propagation, staged DLL payloads, and cleartext C2 beacons, often arriving through trusted vendor relationships or managed service channels.
Operator action: Hunt for the FBI-provided hashes, registry keys, and file paths across endpoints and servers; monitor outbound SMB and HTTP traffic for the noted URIs and user agents; and isolate assets interacting with vendors implicated in shared environments. Disable unnecessary remote administration services, enforce least privilege on network shares, and review supplier remote-access agreements for MFA and logging requirements.
Sources: The FBI FLASH includes indicators of compromise, YARA rules, and mitigation recommendations for defenders.
