Well, let's make it feel a bit more safe then?

First we'll take a look at the open ports on your device. This can be done either with nmap or netstat. You'll be better off with netstat this time.

From your x-terminal run;

That should print the currently open ports and what program is using it. Run this once every few hours and keep an eye open for strange activities.

That, atleast, gives you a bit of a overview of your network but if Epitaph's package does contain malicious sofware this trick probably will not be enough to flush out everything.

As a side note, there are ways to backup your currently installed games, programs and so forth if you end up reflashing.

That's a good idea, but don't be lulled into a false sense of security doing this. It only shows programs running listening on certain ports, waiting for an incoming connection. It won't show you any programs making outgoing connections.

And you're quite right - if someone was writing a malicious back-door they'd probably make efforts to stop it from showing up in a list like this.
