Ghoul

I spent almost 3 days in total to solve this machine, but I’m happy that I have learnt some new things.

Thank you for creating this painful machine @MinatoTW and @egre55 - please make moar of these machines.

For root flag, some basic but useful advice that you may be bored of hearing;

  • monitor processes and file system changes on the machines you get shell
  • enumerate files as much as you can

Good luck.
