UNG0002, also referred to as Unknown Group 0002, is a South Asian cyber-espionage threat actor associated with targeted intrusion campaigns across China, Hong Kong, and Pakistan. The group has been linked to operations including Cobalt Whisper, AmberMist, and Dragon Whistle, and has focused on strategically relevant organizations in defense, aviation, government, academia, energy, electrical engineering, health care, information technology, and related sectors. UNG0002 commonly relies on phishing for initial access, including lures themed as résumés and institutional notices. Its delivery chains frequently use compressed archives containing LNK shortcut files and VBScript components, often paired with decoy documents to improve execution success. The actor has demonstrated repeated use of DLL sideloading, including abuse of legitimate software to load malicious libraries, and has employed in-memory payload execution for post-compromise activity. Tooling associated with UNG0002 includes Cobalt Strike, Metasploit, Shadow RAT and customized variants assessed as INET RAT, as well as the Blister loader. Reported capabilities include persistence through scheduled tasks and other autorun mechanisms, credential theft, browser cookie and session theft, surveillance, remote shell access, and broader post-exploitation control. The actor has also used anti-analysis and defense-evasion measures such as anti-debugging checks and tampering with AMSI and ETW to reduce visibility. Campaign reporting indicates a pattern of espionage-oriented targeting rather than financially motivated crime. Cobalt Whisper targeted defense and aviation entities in China and Hong Kong in 2024. AmberMist targeted government and academic entities in China and Pakistan in 2025. Dragon Whistle targeted the Chinese educational sector, including university students and faculty, using highly tailored social engineering. Overall, UNG0002 is best characterized as a technically capable espionage actor operating against strategic and institutional targets in Asia.

Conducting the Operation Dragon Whistle phishing campaign targeting the Chinese educational sector, using highly tailored social engineering against university students and faculty, followed by a multi-stage malware infection chain that culminates in in-memory Cobalt Strike Beacon deployment.
South Asian espionage actor linked to Shadow RAT and conducting campaigns against defense, aviation, government, and academia targets. Reported operations include Operation Cobalt Whisper and Operation AmberMist, using spearphishing, ClickFix social engineering, LNK delivery, DLL sideloading, and fake government pages.
Conducting large-scale cyber-espionage campaigns across strategic sectors in China, Hong Kong, and Pakistan using phishing emails (often with fake résumés) that deliver ZIP/LNK/VBScript-based infection chains, followed by post-exploitation frameworks and RAT deployment for persistent remote access.
