Threat Actor 🇨🇳 China

MUSTANG PANDA

Also known as: BRONZE PRESIDENT · HoneyMyte · Red Lich · TEMP.HEX · BASIN · Earth Preta · TA416 · Stately Taurus · LuminousMoth · Polaris · TANTALUM · Twill Typhoon

This threat actor targets nongovernmental organizations using Mongolian-themed lures for espionage purposes. In April 2017, CrowdStrike Falcon Intelligence observed a previously unattributed actor group with a Chinese nexus targeting a U.S.-based think tank. Further analysis revealed a wider campaign with unique tactics, techniques, and procedures (TTPs). This adversary targets non-governmental organizations (NGOs) in general, but uses Mongolian language decoys and themes, suggesting this actor has a specific focus on gathering intelligence on Mongolia. These campaigns involve the use of shared malware like Poison Ivy or PlugX. Recently, Falcon Intelligence observed new activity from MUSTANG PANDA, using a unique infection chain to target likely Mongolia-based victims. This newly observed activity uses a series of redirections and fileless, malicious implementations of legitimate tools to gain access to the targeted systems. Additionally, MUSTANG PANDA actors reused previously-observed legitimate domains to host files.

PlugX Meeting Invitation via MSBuild and GDATA

A recent PlugX RAT campaign leverages a spear-phishing email with the subject 'Meeting Invitation' to deliver malicious payloads via DLL side-loading. The infection chain uses a legitimate G DATA antivirus executable (Avk.exe) to load a malicious DLL (Avk.dll), which decrypts and executes the payload from AVKTray.dat. The malware establishes persistence through a registry Run key and communicates with the C2 server at decoorat[.]net over HTTPS on port 443. The campaign demonstrates continued use of trusted binaries, XOR-based obfuscation, and API hashing techniques consistent with China-aligned threat actors.
