On the topic of Linux and RedHat, just got this alert from two colleagues:

just got the following messages from colleagues at other institutions
using RedHat Linux 6:

I've just learned that my Linux box (Dell Optiplex running RedHat 6)
has been hacked into twice in the last week. No damage seems to have
been done, but they used my computer as a platform to hack into others
which were damaged. A chemistry prof with the same system has also
been hacked. Apparently it's a weakness in version 6, which is absent
in 7 (not sure about 6.2). So this is just a warning to any of you
with similar setups to be careful. One time might have been from
on-campus here, but the second seems to have come from New Mexico
State in Las Cruces. My hacking was done once through ftp, which we
then disabled; the second was through telnet, which we have now also
disabled. The cure is to offload everything onto another machine,
install RH7, and then move it all back.

A word to the wise!

And a reply from another colleague

Telnet is a notorious weak point. Better to always use the more secure SSH.

I had a similar problem last summer.
Our computer center hardened up my RedHat unix system with a piece of
software called Bastille.
