Problem Description

*There is some interesting information hidden around this site http://mercury.picoctf.net:27393/. Can you find it?

• Target: http://mercury.picoctf.net:27393/
• Goal: extract a flag
• Initial Observations: A simple page nothing interesting

Tools Used

• web inspect
• Google search

Solution Steps

1. Inspecting the source code
   We can see the first part of the flag in the html.

   Then let’s see the JS file and the CSS file. Then the second part of flag is founded in the CSS file. The JS file gives a hint about the place of the next part of the flag. I searched google with the same question I found that this is regulated by the robots.txt file. So let’s try /robots.txt. oh here is the third part of the flag and there is another hint about the next part of the flag. let’s search about the Apache server and how can it help. How do I change the default index page in Apache? I have found this article on stack overflow after searching default apache files so let’s try /.htaccess

   Another part of the flag and another hint let’s search what does the mac OS help us with the challenge. I used chat-gpt and asked what is special about mac os folders and it responded with this what is special about mac os folders it said something interesting about a hidden folder called .DS_Store so let’s try /.DS_Store

   Finally last part of the flag.
