Power Plan Changed via Remote Web Shell

This rule detects attempts to change the power plan on a system via a remote web shell. It specifically looks for HTTP requests containing 'powercfg' and 'setactive' in the URI, indicating the use of the 'powercfg /setactive' command, which is used to change the active power scheme. This activity suggests an attacker might be trying to manipulate system power settings, potentially for persistence or to interfere with system operations.
