Summary
Threat actors are using scare tactics and adult-only lures to entice victims into allowing a three-staged attack to install malware. Victims are presented with a malicious document that arrives through a spam campaign; one of the analyzed documents claim that a Microsoft Office subscription will expire. Upon attempts made to activate the subscription, the user unknowingly spawns communication with the threat actors C2 and initiates download of the remaining stages with the final payload appearing to be the Agent Tesla malware.
Our Threat Research team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports. This campaign was researched by Inquest and shared publicly.
