I'm pretty sure that my linux box at home has been hacked, and am not sure what to do next.  I found a samba share called [radio] and directory /tmp at root that was just recently created with suspicious files. 

The box in question has slackware 10.2 and is sitting behind a netgear router.  The only hole between the internet and the box was port forwarding for SSH on a non standard port.  I am pretty sure I disabled root the login via SSH. I suppose that this could have been bruteforced - My SSH login is 10 chars and only 3 of them are non-alpha.  Because I'm just running the box at home, and still learning, I have been lax about setting up any rights management.  So if someone did get in thru SSH, they pretty much had full access immediately.

Once I get home from work today, I want to be able to bring my system back up, but not before I am certain I have closed off all vulnerabilities.  Then I'd also like to setup some form of IDS, but I do not know if that is above my skill level.  Of course, I gotta learn some time, so I might as well now?

Any advice is appreciated.  And I'll see you at the east side user group tomorrow.

Thx
Jason
