Admirer is a Linux machine, ranked as Easy at HackTheBox. In my opinion is near to a Medium machine, since there are some rabbit holes, and the foothold is not really obvious (if you don't find the Adminer vulnerability).
Jarvis is a medium difficulty Linux machine. It's named after Tony Stark's household butler and contains several references to Iron Man's universe. It's IP is 10.10.10.143 and today I will show you how I solved this machine.
