The following shows the demo on a text editor. Turning off/unplugging the Arduino will cause the password cracker to restart from 0000.

Thus, we will only start the brute force algorithm when the switch is on, We will be making use of the switch mechanism to turn the BadUSB on/off as shown in my other previous post. To actually type out the passwords, we will be using Keyboard.println(), as this will also enter the password after typing it out.įor simplicity, let's assume we only want to crack systems that uses a 4 digit PIN number as the password, so the character set will be,Ĭhar charset_main = Īnd we will use n = 4 for the password length.Īlso, we will assume there are no mechanisms in place to block multiple attempts, which include stopping/reloading/resetting after multiple failed attempts. Now let's get to the interesting part, where we actually start cracking things using the keystroke injector. Using brute force to actually crack things The output should look like the following.Īll password combinations that can be made from numbers 1, 2, 3 with the password length of 1-4 can be seen here on my Github. Once the uploading finishes, you can open up the Serial Monitor on Arduino's IDE to see the output. Enter fullscreen mode Exit fullscreen mode
