I finished a tiered hacking exercise, and after submitting it was told that the last tier (a machine on the network) was not possible to attack in the given exercise.
The machine was only running rpc.statd on 111 and had a status service listed when I checked rpcinfo.
The box is static (as in, no incoming/outgoing connections exist or will exist)
As a new penetration tester who is up and coming, what do you do when faced with a situation like this? Of course giving up is the last thing you do, but in this specific scenario, is there a feasible solution or is it just a brick wall intended to teach me a lesson?
