Problem:
Mr. Robot
(web, 25 points)
"Disallow it!"
Solution:
This one was kind of cryptic at first and "disallow it!" seemed a little odd at first, however we notice the name of the challenge is "Mr. Robot". This is not only the name of a TV show (a great one I might add), but it's also referring to robots.txt (hence "disallow it"). If we go to ctf.ekoparty.org/robots.txt, we can see the following:
User-agent: *
Disallow: /static/wIMti7Z27b.txt
If we follow the disallow rule to /static/wIMti7Z27b.txt, we'll find our flag.
Flag: EKO{robot_is_following_us}
