This is a writeup for the Inspector Gadget challenge, part of the Hack the box's Cyberapocalypse CTF 2021, category Web.

Prompt​

Inspector Gadget was known for having a multitude of tools available for every occasion. Can you find them all?

Recon​

We are given a url to a website, and upon opening it we see a big ol' CHTB{ slapped right in our faces.

ins gesicht

This clearly indicates, that we're facing a scavenger hunt. So, checking the HTML of the webpage, we find the next piece of the puzzle

<!--1nsp3ction_-->

Surprisingly, robots.txt doesn't give us anything useful, so we look into /static/js/main.js next.

console.log("us3full_1nf0rm4tion}");

Just to make sure, we check whether CHTB{1nsp3ction_us3full_1nf0rm4tion} is the flag, and unsurprisingly it isn't.

So, we logically check the css next, and open /static/css/main.css to find

/* c4n_r3ve4l_ */

Solution​

We can now easily deduce, that our flag is

CHTB{1nsp3ction_c4n_r3ve4l_us3full_1nf0rm4tion}
