SNOWBASIN Propose Change

Actor(s): UNC6692

According to Mandiant, this malware acts as a persistent backdoor that operates as a local HTTP server (typically listening on port 8000). It enables remote command execution via cmd.exe or powershell.exe, screenshot capture, and data staging for exfiltration. This component is where active reconnaissance and mission completion occur. Attacker commands (such as whoami or net user) are sent through the SNOWGLAZE tunnel, intercepted by the SNOWBELT extension, and then proxied to the SNOWBASIN local server via HTTP POST requests. SNOWBASIN executes these commands and relays the results back through the same pipeline to the attacker.
