pnscan running but not installed

Hello to everyone. I have encountered my first security breach! Quite exciting.

I received a few polite emails from abuse networks indicating my outward-facing web & ftp (no mail) server was sending them unfriendly traffic. A quick htop showed that root had executed "pnscan" but I never recalled installing it. I sent it a kill -9, and sure enough, dpkg -s pnscan tells me it's never been installed.

So it seems pretty clear that someone's gotten access to my system in some fashion. The problem is, I don't know where to begin looking. I've scoured logs - I don't see anything obviously fishy there. I've checked bash history - nothing there (though that's easy to circumvent).

Where else should I be looking, or what has my inexperience caused me to miss in the logs? Is this definitely someone who's rooted my server? Could be an FTP vulnerability?

Oops. This should have been posted in Security. I won't repost, I'll let a moderator move it. Sorry for the inconvenience.
