SafetyKatz is a combination of slightly modified version of @gentilkiwi's Mimikatz project and @subtee's .NET PE Loader.

First, the MiniDumpWriteDump Win32 API call is used to create a minidump of LSASS to C:\Windows\Temp\debug.bin. Then @subtee's PELoader is used to load a customized version of Mimikatz that runs sekurlsa::logonpasswords and sekurlsa::ekeys on the minidump file, removing the file after execution is complete.


  • @subtee's PE Loader was slightly modified so some of the pointer arithmetic worked better on .NET 3.5
  • @gentilkiwi's Mimikatz project was modified to strip some functionality for size reasons, and to automatically run the sekurlsa::minidump mode (deleting the minidump file after). If you don't trust my compiled version, feel free to build it yourself :)

@harmj0y is the primary author of this port.
