where_are_the_robots

Desccription :

Can you find the robots? https://jupiter.challenges.picoctf.org/problem/56830/ or http://jupiter.challenges.picoctf.org:56830

Solution

this challenge was very easy. as name is ‘where_are_the_robots’ we can guess that this is something about robots.txt.

what we have to do is search for robots.txt in given url.

https://jupiter.challenges.picoctf.org/problem/56830/
to
https://jupiter.challenges.picoctf.org/problem/56830/robots.txt

click to see robots.txt :

User-agent: *
Disallow: /1bb4c.html

in robots.txt there is a file with name of ‘ /1bb4c.html ‘ , now we have to just go to that page : https://jupiter.challenges.picoctf.org/problem/56830/1bb4c.html

you will get the flag.
