Lsassy LSASS Dump via comsvcs.dll MiniDump from WMI/SMB/Task/DCOM Execution
Detects the use of rundll32.exe to invoke the MiniDump function of comsvcs.dll to create a memory dump of the Local Security Authority Subsystem Service (LSASS). This technique is a common method for dumping LSASS memory to harvest credentials, often used by tools like lsassy and various post-exploitation frameworks. The rule monitors for the specific command line patterns used in this attack, including referencing comsvcs.dll and the 'full' dump argument, initiated by suspicious parent processes frequently seen in lateral movement scenarios.
