In June 2026, infrastructure pivoting from TencShell C2 nodes revealed an active intrusion campaign utilizing AI language models for attack automation. Thirteen Hong Kong-based servers across four ASNs exposed an open directory containing victim source code, custom exploits, operational logs, and cloned login pages with notes in Simplified Chinese. The operation employed Claude Code for execution and DeepSeek-v4-pro for attack logic, targeting government systems in Afghanistan, Thailand, and Taiwan, along with reconnaissance against U.S. government portals. The campaign also pursued financial services firms across Europe, Australia, and Asia. Attackers deployed TencShell implants, webshells, and custom exploits including SQL injection and Laravel deserialization attacks, successfully compromising administrative systems and exfiltrating sensitive data including citizen complaints and government employee information.

A new attack technique called InstallFix targets users by cloning popular developer tool installation pages and presenting malicious install commands. Attackers distribute these fake pages through Google Ads, exploiting users' trust in familiar 'curl to bash' installation methods. The campaign specifically targets Claude Code users, delivering the Amatera Stealer malware. This technique bypasses email security controls and exploits the growing trend of non-technical users adopting developer tools. The attack leverages legitimate hosting services and is part of a broader trend targeting AI-related tools. The payload uses staged execution and various evasion techniques to avoid detection.
