What it detects

This rule detects regsvr32.exe registering a payload located under the non-standard C\Datop directory used by the DatopLoader campaign that exploited ProxyShell to deliver QBot and Cobalt Strike. Attackers abuse regsvr32 to proxy execution of a malicious DLL and evade application controls, so execution from this staging path is a strong loader indicator.
