DarkHydrus is an Iranian state-linked cyber espionage threat group associated with spearphishing, credential harvesting, and malware delivery operations targeting government and educational institutions. The group is known for using socially engineered email campaigns with password-protected archives and malicious Microsoft Office content, including Excel Web Query files and remote template injection via the attachedTemplate technique, to obtain initial access and induce user execution. DarkHydrus has used PowerShell extensively for payload staging and execution, including downloading and running additional scripts while concealing activity with hidden PowerShell windows. The group has also been associated with RogueRobin, a malware family that implements command and control over DNS tunneling and supports covert tasking, result exfiltration, persistence, and anti-analysis behavior. Reported tradecraft includes credential harvesting as a core operational objective and the use of publicly available offensive tools such as Mimikatz, Empire, and Cobalt Strike during post-compromise activity. Known aliases in the supplied material are limited to DarkHydrus.
