Original release date: January 12, 2022

U.S. Cyber Command’s Cyber National Mission Force (CNMF) has identified multiple open-source tools used by an Iranian advanced persistent threat (APT) group known as MuddyWater. According to CNMF, “MuddyWater has been seen using a variety of techniques to maintain access to victim networks. These include side-loading DLLs in order to trick legitimate programs into running malware and obfuscating PowerShell scripts to hide command and control functions.” U.S. Cyber Command has released malware samples attributed to MuddyWater to the malware aggregation tool and repository, VirusTotal.

CISA encourages users and administrators to review U.S. Cyber Command’s press release, Iranian intel cyber suite of malware uses open source tools, as well as their VirusTotal page for more information.
