AhnLab monitored Advanced Persistent Threat attacks targeting South Korea during June 2026, identifying multiple attack types distributed primarily through spear phishing campaigns. Threat actors disguised malicious files as work-related documents, with LNK files being the most common delivery method. Six distinct attack types were observed, employing various techniques including malicious PowerShell commands, AutoIt malware, curl.exe abuse, GitHub repository exploitation, Task Scheduler persistence, DLL side-loading, and Python backdoors. These attacks deployed Infostealers, keyloggers, backdoors, and remote access tools like XenoRAT. Once executed, the malware established persistence, exfiltrated system information, and enabled remote control of compromised systems. Organizations are advised to verify email senders, avoid opening files from unknown sources, apply security patches, and maintain updated antivirus software to mitigate these persistent threats.
