Generate all possible values for the Defcon 18 Badge Ninja Unlock in C#

2:45 PM Posted by Erik Pitti No comments
Part of the fun at DEFCON is the badge hacking contest.  This year I decided to take a hard look at the code behind the badge.  One area of interest was the Ninja Party "Locked" screen, so I decided to see if I could figure out how to unlock it.  I did.  Here's the code I used.  There was also an Excel spreadsheet involved that computed the tumbler values based on the dc18_encode_tumblers function in the file DC18_Badge.c.

Once you figure out the pin encoding (I can’t make this too easy), this code will let you validate the integer result.
