Fingerprints | CyberStart Completion



We’ve found a secret lock-up used by the gang, a big breakthrough! One small problem, it uses an electronic keypad and requires a four digit pin.

We’ve noticed four of the numbers have fingerprints on and we’ve discovered that the lock only allows you to use each number once (i.e. you can’t do 7777). Can you use that information to guess the right code? There are still quite a few possible combinations so you’ll need to be systematic about it.

Tip: Get the right code to get the flag.


The fingerprints show us which numbers are used in the correct combination, it’s just a matter of trying all the combinations with those numbers until you get it right!

How to Solve:

  1. Enter the PIN in the order 2, 4, 7, 5
