What it detects

This rule detects rundll32.exe launched with no DLL or export arguments, a hollowing or injection precursor observed in the Gootloader chain. A bare rundll32 process is typically spawned to host injected code rather than to run a legitimate library export. This anomaly is a reliable indicator of process injection staging.
