Steganography

Hello everyone, I already finished the first part that gives you the data with f0rm4t : account, website, sha1pwd. I am completely stuck there. Can someone give any clue?

div tags in the resulting HTML contains ids of length=1172. No idea where to look.

Challenge page only gives two clues:
* 4 <=> 2
* Recover the flag hidden behind this steganography technique.

How can I get the Genius id? Please share with me a clue or hint.

Hi, I’ve been on this HTML page containing IDs of length=1172 hex char as well.
If you divide it in groups of 4 and apply the hello() algorithm on it, you get something strange that starts and ends with "PKìÍÈôstep3.htmlUT".
I’m thinking that maybe a permutation of the original alphabet "ABCDEF...xyz" could possibly give us another html webpage but that’s a lot of combinations to try.

I haven’t tried to use hashcat and the rockyou database on the md5sum neither because this is a steganography challenge and not a cracking one.

Happy to discuss that if you want :)

Hello Xeypher, what kind of file starts with PK ? :)

you have the rigth idea, just push it a bit further.

Man... I can’t believe I didn’t see that!
Thanks a lot!!!

I’m at the step right after and tested a bunch of things. I think I got the idea but either I got what to do wrong or I’m not doing it right. Is it possible to DM any of you guys?

Does anybody else find a corrupted file when getting this famous "PK"-starting file ?... 😐
No possibility to fix the file up to now. Any clue ?

Nevermind... I messed up with data extraction. Now I have a working file.
Sorry for the flood.

Hi,
I’m also stuck on the PK file part with the corrupted file error on the extraction. Any clue about how to solve this problem ?

Hi,
I’m stuck with the corrupted PK file part too, does anyone have solved ths problem ?
