Re: Hacked - is it my turn?
Yep, it definately looks like you're hacked with those ports open unless
you've installed something that uses them. I'd look into those hidden
processes also but I know there's a problem with procfs or something
that causes some hidden pid's 2-5 or something.
check out http://www.soohrt.org/stuff/linux/suckit/ if in doubt.

Checking 'lkm'... You have 4 processes hidden for ps command
The latter happened to me before and I had gotten info on how this check
doesn't work from this newsgroup ... but the former never showed up
'nmap' to those ports gives me:
PORT STATE SERVICE
1524/tcp filtered ingreslock
31337/tcp filtered Elite
Checksecurity reports this:
Security Violations for su

'tiger' also reports - while performing signature check of system
binaries, that /bin/ping, /usr/bin/chage, /usr/bin/at, /usr/bin/write
and /usr/bin/inetd don not match. This can not be confirmed by aide
(cd-burned database, unsafe binary) or debsums (unsafe binary).
Am I hacked? What else can I do to investigate the situation further?
