To put this problem in context, I have a touch monitor screen whose firmware program is protected by a password.
The firmware program is downloaded over RS232 via a Windows utility program provided by the manufacturer of the touch screen.
The problem is, upon completing the download, the utility program asks for a 6-character alphanumeric password, and I have no idea what it is. The company I bought the screen from has closed down since, so there's nowhere I can get hold of the password.
Since it's an alphanumeric password, (2*26+10)^6 = 56,800,235,584, my questions are:
- How easy is it to crack the password?
- What are the possible ways of cracking it?
- How would you attempt to crack it? (ex. robot program that will try to enter all possible passwords on human's behalf, etc.) What software tools would you use?
