The glimpses of the flag hidden away? http://2018shell.picoctf.com:10157 (link [1] ) Hints: (1)     What part of the website could tell you where the creator doesn't want you to look? Solution: So the name and hints are telling use to look at robots.txt which is a file that is used to have search engines not scan certain directories Lets check the robots.txt for this site http://2018shell.picoctf.com:10157/robots.txt User-agent: * Disallow: /143ce.html Ok they don’t want the robots to look at 143ce.html http://2018shell.picoctf.com:10157/143ce.html So much depends upon a red flag picoCTF{th3_w0rld_1s_4_danger0us_pl4c3_3lli0t_143ce}
