What it detects
This rule detects a process named dllhost.exe running with ProcDump style arguments to create a full memory dump of lsass.exe as observed with the PipeMagic backdoor. The genuine dllhost COM surrogate never accepts these switches so this is a renamed ProcDump used to steal credentials from LSASS. Capturing LSASS memory yields hashes and tickets for further compromise.
