"People who get violent get that way because they can’t communicate."
It's like an instinct, whenever I see a challenge title related to Mr.Robot series, I check the /robots.txt page. xD Generally robots. txt file is a text file that tells web robots (most often search engines) which pages on your site to crawl. So on visiting the /robots.txt, http://chall.csivit.com:30231/robots.txt we see a path which is disallowed to the web robots.
# Hey there, you're not a robot, yet I see you sniffing through this file.
We append this disallowed path
/fade/to/black to the challenge url, http://chall.csivit.com:30231/fade/to/black and we get the flag.
