Author: cyclone
URL: https://github.com/cyclone-github/challenge/tree/main/RiddledHistory
Description:

• A fun challenge consisting of 4 main sets of challenges, each with their own set of hints, riddles and quests.
• Challenge contains hints of fairy tails, classic movies and American history, all incorporated into hashes, encrypted files, and finishes strong with a simple, but challenging, reverse engineering "capture the flag".

Experience Required:

• hash cracking = Beginner / Intermediate
• reverse engineering = Beginner / Intermediate

Funfacts in a fairy-tale atmosphere on this challange. I managed to break a few file hashes, although Dorothy's spreadsheet was not for me to look at... Just as well to see the contents of 100 SHA1-like hashes was not for my sensitive eyes. I did get to the july4th.bin file, but I have the system misconfiguration that I was unable to read the flag too. Should I try to decompile/recompile binary on a software so praised by the NSA? I rathergive up.

july4th.bin hint:

Spoiler

Decompiling is a great way to fine the flag. You're probably just a few digits off.

Tempting, but I'm going by the rule 'measure your strength by your intentions'. I am not familiar with software code and I think I will stay with my hobby of simpler hashes.

Decompiling is pretty simple on july.bin, but you can also check the walk-through which contains its source code and also hash:plains for the challenge.

Here's an online decompiler for july.bin:
