A developing threat activity cluster has been found using Google Ads in one of its campaigns to distribute various post-compromise payloads, including the recently discovered Royal ransomware.

"Observed DEV-0569 attacks show a pattern of continuous innovation, with regular incorporation of new discovery techniques, defense evasion, and various post-compromise payloads, alongside increasing ransomware facilitation," the Microsoft Security Threat Intelligence team said in an analysis.

The threat actor is known to rely on malvertising to point unsuspecting victims to malware downloader links that pose as software installers for legitimate apps like Adobe Flash Player, AnyDesk, LogMeIn, Microsoft Teams, and Zoom.

The malware downloader, a strain referred to as BATLOADER, is a dropper that functions as a conduit to distribute next-stage payloads.

"DEV-0569 has used varied infection chains using PowerShell and batch scripts that ultimately led to the download of malware payloads like information stealers or a legitimate remote management tool used for persistence on the network," the tech giant noted.

The use of Google Ads to deliver BATLOADER selectively marks a diversification of the DEV-0569's distribution vectors, enabling it to reach more targets and deliver malware payloads, the company pointed out.
