[cobalt-security] Raq3 Hacked

[e13372002 <e13372002@xxxxxxxxx>]

I'm sorry to send a 2nd email but the first I sent is
"awaiting moderator approval"
I'm posting from a yahoo account for obvious reasons

Well, my raq 3 running all the latest patches, ssh
only and no CGI (except the cobalt web-gui) was
hacked.

After a hard disk crash about a month ago, I had a
fresh installation, and I didn't install tripwire or
any of the other stuff I should have installed.  I
figured because I host just a couple non-profits,
local bands and clubs, it didn't really need to be
ultra-secure.  I figured wrong.

The machine crashed lastnight/this morning.  

When rebooted, I could not get my personal email
because of a "corrupted mail drop" so I logged into
the machine using that user account and could not use
the "ls" command in that home directory because of
permissions changes. Also, pine could not read my
mail, but "mail" could.

So I logged into the admin account and saw this:

Last login: Wed Sep 25 16:11:00 2002 from
mkc-65-30-68-235.kc.rr.com

I did not log in yesterday and that is not one of the
IP addresses that would be me.

I did a cat .bash_history and got this:

ls
cd /tmp
ls
ls -lar
netstat -a
ls -lR
ls -lar
ls -larR
cd /
ls
netstat
exit

I know that was not me.

I've changed the root/admin passwords and am now
looking for more evidence on the machine.

Checked Passwd and couldn't find any new users.

Advice?

RaqHaqFaq anywhere?
