What it detects

This rule detects an Explorer TypedPaths registry value that records a PowerShell command or HTTP URL, the forensic artifact left when a FileFix lure has the victim paste an obfuscated command into the File Explorer address bar. TypedPaths normally stores browsed folder locations, not scripts or web addresses. A command string or URL in this value indicates the FileFix address-bar execution technique.
