Baby

Man, this is one of the easiest challenges I ever had in HTB. No tools needed, just use the computer alternative of the writing pad :wink:

Hi, I’m new in Linux and I don’t know many of features and tools that it offers. Can you give me a hint how to solve this challenge please?

I would take the time to understand RE a bit and play with the tools available before diving in too hard.

You can feel free to find me on Discord as heuvosenfuego#1515 and I’ll walk you through.

Anyone else having a problem opening the download? I cant unzip it. Gives error

I’ve Just checked the archive. Everything is fine

I never did reversing but have some experience programming in C so it took me a bit long, about 10-15 minutes to solve this challenge.

I opened the file with v** and found a key and the flag as well but because of encoding it wasn’t usable.

Chef told me what file type it was, used the key and challenge solved.

Tried h** **p as well with Chef but the flag wasn’t usable that way. Did some research on Big Brother and learned how to use r which I’ll be using in the next challenges as well.

I have an error too :
skipping: baby unsupported compression method 99

Is it part of the challenge ? Because on windows I found the key and what seems to be the flag. But on linux there is this problem.
anyone ?

Totally agreed. And remember, it’s just a file that can be read, wrote and …

… used to file the bars of your cell and escape in search of the legendary Monkey Island?

Thanks for hint @IvanGlinkin and the others :slight_smile:

Spoiler Removed

it was my first revers engineering task and it was fun!

It took me longer to unzip the file than solve the challenge. If you are having trouble unzipping this on a linux box, try using 7zip to unpack it.

I can see the flag with my “tool” but some parts are missing/unreadable… Is it just a matter of tool settings ?

ok, flag found :slight_smile:

Going into this never RE anything before. Overall super simple and fun challenge. If anyone needs help you can PM me.

Nudge: Download Ghidra and look up some walkthroughs for other CTFs using it to get familiar with the tool. Also very slight programming experience will help ( By slight I only mean conditional statements)

The challenge mentions 4 ways to solve. I’ve found 3 (abbreviated so as not to give it all away):

  1. strings, then run
  2. r2
  3. strings | tr | grep

Anybody have any different methods?

EDIT: If these method descriptions are too specific, let me know- I’m new to htb but it seems like this level of description is not too much of a spoiler.

*facepalm* I thought extracting the archive WAS the challenge :tongue:

If you haven’t already figured it out, Google is your friend with that zip error.

I did the whole thing on a kali linux vm
