[CRYPTO] Walzer

Anyway I got it, maybe its worst ever crypto challenge in htb.

If need help ? you can send pm.

Yeah, I don’t know man, but I share the same opinion as my friends @R4J @sampriti @xct . How this challenge got accepted is beyond me and I’m really pissed off at whoever tested this challenge. We shouldn’t be mad at the creator, he tried to teach us something. He made a mistake and owned it. But who the ■■■■ tested this ■■■■ and thought like “oh yea, this is fucking good, lets smash 40pts on top of it”. Well guess what. It’s fucking easy if it’s fucking solved with a guide. To all the testers, please at least try the challenges without guide. You guys aren’t perfect, we know that. But don’t ■■■■ us over like this.

PS: I have a cool crypto challenge for you guys. Guess the number from 1-1337. Send me a DM with your guess. First blood receives a star sticker that says “master at guessing”.

UPDATE: I’m getting a lot of messages of people asking for hints. Here you go: The number is between 1 and 1337.

UPDATE 2: I’m getting a lot of messages whether 1 and 1337 are included. No, they are not.

UPDATE 3: Here’s a hint. Reverse the following piece of code and you will get the flag.

import random
print("HTB{%i}" % random.randint(2, 1337))
while challenge.submitted:
    htb.release(challenge)

You may be right, you may be wrong. But you should really support your opinions more politely. That’s being said, I leave you all alone.

Sorry, I guess :frowning:

My bad. Never thought this could be tagged as spoiler.

What threw me off is that in Waltz you do a certain pattern and then repeat it kind of “backwards”, but that never happens here. You’re just doing the “equivalent” to the forward movement a few times. I honestly don’t think it’s a bad challenge, but there could have been more information provided on the steps involved, since at least one of them is found literally through guessing and/or bruteforce.

Lol it was not a spoiler. It was other text encoded the same way.

THIS JUST WAS THE WOREST CHALLANGE EVER WITH THE WOREST FLAG FORMAT I SEEN

Maybe I will create a challenge that requires you to guess the number I thought of in my head between 1 and 1000 and call it information asymmetry. For fucks sake.

ITS 42 ISN’T IT - YOU KNOW I’M RIGHT - GIVE ME THE FLAG NAO

Snake did nothing wrong

is waltz related to music,dance or just completely random

As you may have noticed in the video, basic Walzer is a repeated sequence of three steps. The teacher calls them “step”, “side”, “close”.

Since easy cryptography is involved, you should map these steps with some kind of basic cypher algorithms.

Looking at the starting position, an educated eye should catch the first “step” immediately. What about the others? You choose, but choose wisely because, after three steps, you have to be in a different place, but in the same position.

And remember: you’re dancing, come on don’t be shy, let the music flow and continue. After all, the teacher says: “we can keep that going until the end of the song”. And we do know when the music stops, don’t we?

I hereby want to apologize to the author and the HTB staff for my rage. We shouldn’t have raged this hard about the challenge and expressed ourselves in a more polite way. After all this is just a mistake, and we all make mistakes. Let’s not discourage the author from making more challenges! I’m sure he got much more in store than this!

The challenge playtesters need to learn what “crypto” means. Apart from Optimus Prime, the last 4 crypto challenges released have all been dumb guessing games, and a poor reflection of how fascinating and educational good crypto CTF challenges can be.

Still have no idea, should I try rotation and combinations of all pieces of base64 codes?

A worthy replacement for snake

Any help with this? I have no idea what the hints mean

I dont think this challenge is as bad as the above comments make out. Yes the hints are terrible, and yes I’d prefer more modern crypto challenges, but the actual meat of this challenge practices basic skills.

@WarrenVos - (and any one else having a problem starting) Look for a pattern in the bytes after the first decoding, think about what that might imply :wink:

Hello everyone, this is my first posft.

I’m struggling with this challenge, how can I ask for a hint here? I’ve came across some kind of flat that has a heart (<3) but dunno how to continue.

Any help is welcome!

All you ppl are some bad pu$$!35, leave the creator alone if you can’t solve it, its not his fault, its yours because you know ■■■■! Idk why are you here, to entertain or to be a real cyber security or a real good hacker.

I bet you people that get into hackthebox is in thanks of other people who posted videos how to get in. If you aim to be a cyber security or a hacker, you don’t have to blame the creator how hard is to decipher a hash because if you would be in real life, you would ■■■■ everything up!!

What if you get to get some real hashing in real life from a black hacker, you would shout at him why he made that so secure that your little brain can’t decipher it?? Get a life and if you can’t handle this go away rather that you say some bs…

Wow, so edgy. This challenge has nothing to do with real cybersecurity and a “black hacker” worth his salt would base his security on actual cryptography. I’d rather learn about the ways that RSA, Diffie-Hellmann can be broken in practice than waste learning time trying to decipher a dumb challenge created from stringing together obscure ciphers in Cyberchef.
