What it detects

This rule detects HTTP requests to the default request URIs used by the PowerShell Empire C2 framework. In the WithSecure C2 and Exfiltration Lab 1 an Empire agent beacons to server paths such as /admin/get.php and /login/process.php while impersonating a Microsoft-IIS server. Attackers use these hardcoded default routes for command retrieval and result submission over HTTP.
