It was terrible. What's a difference with bruteforcing the password and a CRC32? The other thing is the cracker doesn't work on my computer for some reason. Even if it did, is the purpose of solving CTF to just put it to the already made software that will print you the ready flag?

interesting challenge, thanks

its very easy with https://github.com/kmyk/zip-crc-cracker

very good and interesting, but this is definetly a forensics chall. Also a small pun hint would have helped

No way to solve it without the help of the comments. The web does not give you any hint on the matter.

use this : https://github.com/kmyk/zip-crc-cracker

Read this and you will be able to do it. i will go https://github.com/kmyk/zip-crc-cracker

Is the hint "STRONG"?

no, it is a fact. So dont try to brute force the password

Any Hint?

I solved it in less than 1 hour, especially thanks to an hint within the comments below. Nevertheless, i have learned something new (especially to look beyond my own backyard: the weakness exploited to solve this challenge has always been under my eyes, just never thought about it) ... Thanks for the nice challenge ...

Interesting challenge, learned something new about zip files and how they are made.

Fascinating. Thanks Rivit, now I know zip-compressed with password may also be insecure ;)

As said below: (1) thanks for the hint (no bruteforcing, no wordlists) (2) learnt something new: thanks

It takes almost 3 months to come to the point of this challenge. Finally SOLVED thanks RIVIT for this fascinating challenge

can you help me ...i wanna learn how

Thanks Rivit, I learned something new :)

nice challenge, learned a lot about zip

one of the better challenges i've seen on this site

very good and interesting, but this is definetly a forensics chall. Also a small pun hint would have helped

Any Hint?
