Inside Kimsuky's Abuse of Legitimate Remote Control Tools Across Northeast Asia

Kimsuky conducted spear phishing campaigns against South Korean and Japanese targets during the first half of 2026, distributing LNK malware through OneDrive share links. The malicious files established scheduled tasks that periodically fetched PowerShell scripts from command-and-control servers to profile systems, exfiltrate Thunderbird and Outlook email data, and log keystrokes. The threat actor installed legitimate remote control software including Chrome Remote Desktop and AnyDesk to evade antivirus detection and maintain multiple access channels. A malicious Chrome extension designed to steal Gmail data exhibited characteristics of AI-generated code, featuring Korean comments, debug strings, and Unicode emoji throughout. The operation employed rotating infrastructure and compromised legitimate Korean servers as command-and-control nodes to impede tracking efforts.
