Cybereason issues Threat Alerts to inform customers of emerging impacting threats, including recently observed DarkGate Loader. Cybereason Threat Alerts summarize these threats and provide practical recommendations for protecting against them.
Cybereason Security Services is investigating incidents that involve DarkGate Loader, a modular loader delivered via phishing email and responsible for deploying post-exploitation payloads.
Threat Actors deploy DarkGate Loader as an AutoIt script, which contains an encrypted payload. The AutoIt script decrypts and injects the payload into different processes. The execution of DarkGate Loader ultimately leads to execution of post-exploitation tools such as Cobalt Strike and Meterpreter. This Threat Alert provides an overview of an attack involving DarkGate Loader.
The purpose of DarkGate Loader is to deploy post-exploitation tools while evading detection.
