Context

UNG0901 is a cyber-espionage threat actor targeting Russian entities, particularly in the aerospace and defense sectors, utilizing spear-phishing tactics. They deploy the EAGLET backdoor, which exhibits functionalities similar to the Golang-based PhantomDL used by the Head Mare group, including shell, download, and upload capabilities. Notable overlaps in file-naming conventions and targeting strategies further reinforce the connection between UNG0901 and Head Mare.
