ComRAT is one of the earliest known backdoors used by the Turla APT group. Turla, also known as Snake, has been active for over a decade with a long history of the watering hole and spear-phishing campaigns against embassies and military organizations at least since 2004. The new version of the malware uses an entirely new code base and is far more complex than its earlier variants, according to cybersecurity firm ESET. It leverages Gmail’s web interface to covertly receive commands and exfiltrate sensitive data.
