Yup.  You should assume this anyway after you've been broken into, even if
you have no evidence that they got root.

Bastille Linux, if you're running a distro that it supports.

If you're the Debian type, I think a daily 'apt-get dist-upgrade' in cron
will keep you a step ahead of the bad guys.

And the tool you need right now is your distro's installation procedure,
because you need to wipe the machine's disks and completely reinstall it.
