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
