mhaag-spl b3b37719e7 Update sysmon_lsass_memdump.yml
Updated Sysmon Lsass Memdump to detect other memory dumping techniques from mimikatz, nanodump, invoke-mimikatz, and so forth. This adds additional GrantedAccess permissions and adds ntdll.dll to CallTrace. Tested with Atomic Red Team T1003.001, MimiKatz, Invoke-Mimikatz and Cobalt Strike.
