Executive Summary
In September 2026, a regional news outlet was identified as a victim of a sophisticated ClickFix infection chain. The attack began with malicious JavaScript injected into the news site via a third-party CDN, which served social engineering overlays to visitors. These overlays tricked users into executing obfuscated PowerShell commands through the Windows Run dialog, leading to a multi-stage infection sequence.
The technical execution involved reflectively loading heavily obfuscated .NET DLLs into memory to avoid disk-based detection. The malware, suspected to be a variant of StealC, employs advanced evasion techniques including ConfuserEx protection, anti-debugging checks, and process injection into legitimate Windows and browser processes like csc.exe and chrome.exe.
This campaign represents a significant threat to user privacy and organizational security, as the final payload is specifically designed to exfiltrate browser-stored credentials and session tokens. The use of social engineering to bypass technical controls, combined with memory-only execution, makes this threat highly effective against standard endpoint security measures.
