Detects attempts to dump LSASS process memory using WerFault.exe. This technique is often used by tools like Mimikatz, NanoDump, Invoke-Mimikatz, Procdump, or Taskmgr to extract credentials from the Local Security Authority Subsystem Service (LSASS) process. The rule specifically looks for WerFault.exe accessing lsass.exe with a GrantedAccess of '0x1FFFFF', which indicates full access.
Detects a possible process memory dump of LSASS using processes with whitelisted filenames (like TrolleyExpress.exe, ProcessDump.exe, dump64.exe) to evade detection by security products like Microsoft Defender. The rule specifically looks for access to lsass.exe with granted access rights commonly associated with memory dumping.
Detects remote access to the LSASS process via WinRM. This could be a sign of credential dumping from tools like mimikatz.
Detects LSASS process access requests from a source process with the "dump" keyword in its image name.
Detects a possible process memory dump that uses a white-listed filename like TrolleyExpress.exe as a way to dump the LSASS process memory without Microsoft Defender interference
Detects process LSASS memory dump using Mimikatz, NanoDump, Invoke-Mimikatz, Procdump or Taskmgr based on the CallTrace pointing to ntdll.dll, dbghelp.dll or dbgcore.dll for win10, server2016 and up.
Mimikatz Use
Sigma
This method detects mimikatz keywords in different Eventlogs (some of them only appear in older Mimikatz version that are however still used by different threat groups)
