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.
