Problems and dead ends

The biggest problem that I’m running into is how THM labs are really slow when you are working with more than one machine, e.g. having a target machine and then a attackbox, it’s probably better to start using OpenVPN to connect than doing everything on the thm site.

What I will revisit

  • More hands practise with IDOR and CSRF
