MuddyWater	MITRE ATT&CK lists RemoteUtilities as software used by this actor; track it as remote access and operator control behavior.

Hash And IOC Status

Actor	Status	Reference
MuddyWater	Hash not committed; use the linked MITRE references and original source reports for current IOCs.	SRC-MITRE-G0069

Hashes and IOCs on this page are source pointers or representative public indicators. They SHOULD be refreshed from the linked source before operational use and MUST NOT be used alone for actor attribution.

Defensive Hunting Notes

Actor	Hunting Notes
MuddyWater	Hunt for RemoteUtilities execution or artifacts only in context: unusual parent process, unexpected host role, suspicious account, external staging, or proximity to the actor intrusion chain.

Handling Notes

Actor	Handling Notes
MuddyWater	Common or dual-use tools require local allowlisting and must not be used alone for actor attribution.
