MuddyWater is an Iranian state-sponsored cyberespionage group first observed in 2017 and publicly identified by U.S. Cyber Command as a subordinate element of Iran’s Ministry of Intelligence and Security (MOIS). It is also tracked as Seedworm, Mango Sandstorm, Mercury, Static Kitten, TEMP.Zagros, TA450, Earth Vetala, Cobalt Ulster, Boggy Serpens, ITG17, Yellow Nix, and ATK_51. Its operations focus primarily on the Middle East and Central Asia, targeting government, military, telecommunications, academic, and information technology organizations. Documented campaigns include attacks against entities in Turkey and Tajikistan. The group gains access through targeted spearphishing with malicious attachments and links, including messages sent from compromised third-party accounts. Its document-based attacks have combined exploitation of CVE-2017-0199 with malicious Office macros to deliver POWERSTATS. A March 2024 campaign used PDF attachments containing links to archives carrying Atera Agent installers. MuddyWater also abuses legitimate remote-access software, including ConnectWise and Remote Utilities, and has exploited Microsoft Exchange through CVE-2020-0688 and the Ruler framework. Other documented exploitation includes the Netlogon vulnerability CVE-2020-1472 and the Langflow vulnerability CVE-2025-3248. MuddyWater combines custom malware with publicly available offensive tools. Its toolset includes POWERSTATS, PowGoop downloader variants, the Mori backdoor, and custom reverse-shell tooling. It uses DLL side-loading, obfuscated PowerShell and VBScript, Base64 encoding, and Invoke-Obfuscation to conceal execution and command-and-control functionality. Mori communicates through DNS tunneling, while Chisel, SSF, and Ligolo support access to systems inside compromised networks. Persistence mechanisms include Registry Run entries and scheduled tasks. The group steals credentials with LaZagne, Mimikatz, and ProcDump, including passwords stored in email applications, and performs host reconnaissance such as process enumeration. Its operations demonstrate sustained refinement of custom tooling alongside continued reliance on legitimate administration software and open-source offensive utilities.
