Description

This analysis delves into a recent surge of malicious email campaigns by the DarkGate threat actor, employing novel tactics to distribute malware. These campaigns leverage a technique called 'Remote Template Injection' to bypass security controls and deceive recipients into executing malicious code embedded within seemingly innocuous Excel attachments. Notably, the actor has transitioned from utilizing AutoIT scripts to AutoHotKey scripting, executing the final DarkGate payload directly in memory, without writing it to disk. This continuous evolution in infection chains demonstrates the actor's adaptability and determination to evade detection.
