PACTF_2017: Haystack

Category: Points: 60 Description:

That’s a lot of data… but at least it’s signed! I’ll bet that at least one signature doesn’t match up, though. One of ‘em has a bit of cuil. It’ll be like finding a needle in a haystack… haystack.json


Yes, I know that the RSA key format doesn’t really matter in this scenario (considering there isn’t much of a format).


Thank god we are given the key.


Therefore, the key is sometimes_needles_in_a_haystack_can_prick_you.
