#ESETresearch has analyzed the evolution of #MATCHBOIL, a C# downloader used by the 🇷🇺 Russia-aligned APT group UAC-0099 to download, install, and persist another payload. @reib3n1 https://t.co/hdWz0uqbQC 1/7
We found an AI-themed malware lure delivering the shadow-c2 implant through a malicious PyInstaller wrapper, using Claude Setup.exe as the visible decoy 🔎
🎭 The PyInstaller wrapper launches Claude Setup.exe while decoding and executing the hidden shadow-c2 Python implant in memory
🔓 shadow-c2 supports browser and Discord credential theft, keylogging, clipboard monitoring, screen capture, webcam/microphone access, remote shell, and process control
🛡️ It includes VM, sandbox, debugger, and sleep-evasion checks, plus multiple persistence mechanisms
🔐 C2 communication uses WebSockets with RSA-OAEP key exchange and AES-GCM encryption
🌐 The configured C2 is 192.168.1.11:5000/ws, a private/local address — potentially consistent with the sample being one component of a broader intrusion set

The switch to SparroWocky happened shortly after FamousSparrow started targeting Latin America almost exclusively, going mainly after governmental entities. This is most probably part of 🇨🇳 China’s reaction to the increased 🇺🇸 US interest in the region. 2/6
