Internet-Facing Windows Admin Center Listening on Default Port (Non-2.6.4 Version)
This rule detects Windows Admin Center (WAC) creating a listening connection on its default port (6516) on internet-facing devices, specifically when the WAC version is not '2.6.4'. This could indicate an unpatched or vulnerable version of WAC exposed to the internet, potentially making it susceptible to exploitation.
