Cryptography
Okay, so we found some important looking files on a linux computer. Maybe they can be used to get a password to the process. Connect with
nc 2018shell1.picoctf.com 5221. Files can be found here: passwd shadow.
If at first you don't succeed, try, try again. And again. And again.
If you're not careful these kind of problems can really "rockyou".
Do john --wordlist=rockyou.txt shadow
The file rockyou.txt can be found from /usr/share/wordlists/rockyou.txt.gz.
Extract the file by doing gzip -d rockyou.txt.gz
Connect to service and enter in credentials to get the flag.
$ nc 2018shell1.picoctf.com 5221
