What it detects
This rule flags execution of the CreateMiniDump.exe hack tool by matching its executable name and an associated imphash pattern. CreateMiniDump is commonly used to produce a memory dump of the LSASS process, which can facilitate offline credential extraction and other post-exploitation steps. It relies on Windows process creation telemetry, including the process image path and imphash metadata.
