Can you find the robots? https://2019shell1.picoctf.com/problem/12267/ (link) or http://2019shell1.picoctf.com:12267
This challenge consists of a website with a hidden page disclosed in robots.txt. View the hidden page to receive the flag.
We are first presented with a page displaying "Welcome" and "Where are the robots?" This suggests that there may be something at robots.txt.
User-agent: *
Disallow: /713d3.html
The robots.txt page displays one disallowed html file. Let's view it. Navigating to /713d3.html gives us the flag, picoCTF{ca1cu1at1ng_Mach1n3s_713d3}.
