A JavaScript and VBScript Based Empire Launcher - by Cn33liz 2017

Both Launchers run within their own embedded PowerShell Host, so we don't need PowerShell.exe. This might be usefull when a company is blocking PowerShell.exe and/or is using a Application Whitelisting solution, but does not block running JS/VBS files.

Empire PowerShell Host build by Cn33liz and embedded within JavaScript using DotNetToJScript from James Forshaw https://github.com/tyranid/DotNetToJScript

Usage:

* Setup a new Listener within PowerShell Empire.

* Use the Launcher command to Generate a PowerShell launcher for this listener.

* Copy and Replace the Base64 encoded Launcher Payload within the StarFighter JavaScript or VBScript file.

* For the JavaScript version use the following Variable: 

  var EncodedPayload = "<Paste Encoded Launcher Payload Here>"

* For the VBScript version use the following Variable: 
  
  Dim EncodedPayload: EncodedPayload = "<Paste Encoded Launcher Payload Here>"

* Then run: wscript.exe StarFighter.js or StarFighter.vbs on Target, or DoubleClick the launchers within Explorer.

BlueTeam Advice

  • Instead of Blocking PowerShell.exe, make sure you enable PowerShell Constrained Language to all of your users that do not need to use PowerShell for their daily work.
  • Use Device Guard and make sure you only allow signed Java, VBS and PowerShell Scripts to prevent Malicious use.
