>use your brain and use the computer to hack stuff

Listen, you ARE the "tech guy," but seriously? Hacking is not nearly as simple as it is in the movies! You need proper and often specialized tools to hack basically anything these days, so trying to "hack" a device that has a command prompt and a weird other screen with a stick figure is just absurd.

Maybe you could try running some commands on the terminal, though. Possibly wouldn't hurt to try. Probably will. At best it's around 50/50 odds. Could also get you out of here, potentially. You've honestly got no idea what this thing could do.
