Lsassy Remote LSASS Dump via comsvcs.dll MiniDump (Bumblebee/Akira Campaign)
Detects remote LSASS memory dumping patterns associated with the lsassy tool, leveraging comsvcs.dll to create memory dumps of the LSASS process. The rule identifies suspicious command lines involving comsvcs.dll ordinal-based exports (ordinal #+000024), tasklist enumeration for PID discovery, and subsequent dump file creation within \Windows\Temp\. It monitors remote execution methods often observed in Bumblebee and Akira campaigns, such as WMI or DCOM/MMC-based process spawning.
