A sophisticated macOS campaign has been discovered using a fake Zoom installer to deploy Overlord RAT, an open-source remote access framework. The attack employs a .NET-based downloader disguised as ZoomMeetings, representing an uncommon approach for macOS threats. The multi-stage attack fingerprints the victim's system to deliver platform-specific payloads for macOS ARM64, macOS Intel, or Windows from attacker-controlled infrastructure. The second stage deploys Overlord RAT with extensive capabilities including keylogging, screen capture, audio and webcam access, filesystem manipulation, and remote desktop streaming. The malware communicates with command-and-control servers over encrypted WebSockets and maintains persistence through LaunchAgents. The campaign shares characteristics with previous North Korean operations, including similarities to FlexibleFerret malware and the Contagious Interview campaign.
