Brute Force BIOS Cracking
Cracking BIOS passwords is usually done by reading a BIOS chip with a programmer and extracting the password from it. There is another way to do it and that's by using a brute-force method. This method doesn't always result in finding the password and takes a lot of time.
So, someone figured out how to automate the BIOS brute-force crack method by using Arduino (AVR) to emulate USB keyboard and by sniffing on VGA output from graphics card to test for a certain pixel on screen when the password is entered correctly.
