Doing a netstat on my server, I find a strange connection.
It's a crond-job with Apache as owner, and it seems to go to an

that knows what this is??
Do you have awstats installed? Check and see if you have any hidden
directories in /tmp. There is an awstats exploit that allows uploads
as the apache user. I found a process running as apache called
init.d on one of my servers. It too was initiaiting connections out
to IRC. The EnergyMech irc bot was uploaded and executed from the
/tmp/.bin directory.
This person has explained in detail his experience.

Maybe this is what happened to you.
Just FYI, awstats-6.4 has that particular security hole patched. If
you are running anything older, upgrade now!

I'm running FC2 now. I did a netstat and didn't see any connections
I couldn't account for.
I have set up for FC2 legacy updates, and done a
# yum update
which pulled several packages.
What should I do in order to defend against this sort of attack?
I'm not familiar with iptables, though I just looked, and it
didn't look like much was blocked. I don't have awstats, I guess,
as
$ su -
# man awstats
No manual entry for awstats

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
