description: This rule flags file events where a file name contains the path segment for Advanced IP Scanner 2 within the user Temp directory (\AppData\Local\Temp\Advanced IP Scanner 2). Attackers and administrators may use network discovery tools, so locating this specific binary in a transient user-writable location can indicate automated tool staging. It relies on Windows file event telemetry that includes TargetFilename so the rule can match the specified substring.
