Hi,

There is a package/port call chkrootkit. It can help determin your
vunrabilities, and how you were hacked.
I suggest you look for files with invalid dates and times on you fs.
Such as /usr/sbin/sshd for example.
I would then cvsup to 4.4-RC as alot of security issues will be eliminated.
Make world should also correct any files that may have been altered an/or
tampered with.

Hope this helps a bit! :>
