What it detects

This rule detects a process named sslconf.exe running from a user AppData EdgeUpdate\Install path, matching the SectopRAT payload staged by the FakeAgent Claude Desktop malvertising campaign. The binary masquerades under an EdgeUpdate directory name in a user-writable location that legitimate Edge updater components never use. Execution from this wrong context indicates malware persistence and RAT activity.
