Threats Tagged 'kimjongrat'

In May 2026, security researchers observed an attack campaign distributing KimJongRAT through GitHub and other legitimate services. KimJongRAT, used by the North Korean APT group Kimsuky since 2013, combines information stealing and remote access capabilities. The infection chain begins with phishing emails containing shortened URLs redirecting to GitHub Releases hosting malicious ZIP files. Victims execute LNK files that download HTA files from GitHub, which then retrieve subsequent payloads from Google Drive. Recent variants demonstrate significant evolution: they now dynamically fetch C2 addresses from external sources rather than hardcoding them, enabling operators to maintain persistent access despite infrastructure takedowns. Additionally, new versions include MeshAgent RMM installation for redundant access. The campaign exemplifies Living Off Trusted Sites (LOTS) techniques, abusing legitimate platforms like GitHub, Google Drive, and Dropbox to evade detection.

This analysis examines the latest attack flow of the KimJongRAT variant, attributed to the North Korean threat actor Kimsuky. The malware has evolved to include both PE-based and PowerShell-based attack chains, which have been merged into a single workflow. The attackers use phishing emails for initial access, leveraging GitHub and Google Drive for malware distribution. The malware exfiltrates sensitive data including browser credentials, system information, and keystrokes. Additional activities by the same actor include credential theft through phishing sites and spear-phishing campaigns targeting South Korean users. The analysis provides evidence supporting the attribution to Kimsuky and highlights the ongoing development of variants and infrastructure, indicating successful attacks.
