AI Summary
A malicious Go module, github.com/kaleidora/dnsub-scanning-tool, serves as a lure to deliver a multi-stage Windows malware chain involving hidden PowerShell execution and encrypted payload resolution via public dead drops. The campaign, tracked as Operation Muck and Load, leverages a network of 222 GitHub repositories across 190 accounts to create credibility and scale for malicious or deceptive software projects. These repositories use synthetic activity to appear recently maintained, facilitating social engineering and malware distribution. The final payload includes RATs such as AsyncRAT, Quasar, and Remcos, along with infostealers like Vidar, enabling credential theft, screen capture, and persistence.
