题目考点

解题思路

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.
# SEO you later!
# Now get off my lawn.
Disallow: /fade/to/black

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.

Flag
