Behind the scenes | Hackthebox Writeup

Hello and welcome to my Blog!

This is a writeup for behind the scenes hackthebox challenge, which can be found here https://app.hackthebox.com/challenges/behind-the-scenes

Let’s get right into it.

After downloading the zip file and extracting it with the password “hackthebox” we get a file, on using file command:

lets run the file to see what it does.

we see that it requires a password, maybe we can get something on strings

strings -n 4 behindthescenes

we see something that seems like a flag:

But where is the password?

From here we can view the hex of the file maybe we can get something, I use xxd:

xxd behindthescenes

On viewing the output if we scroll down we see the command “./challenge <password>” recall that output when we ran the file, then it is followed by some string, that must be the password, right?

If we input the string found as the password:

NB: You must remove the “.” in between the string found in the hex.

We get our flag!

That’s it thank you for reading this.
