I have a Fedora Core 2 server that crond is pegging out my CPU usage. Here's a shot from top:

It's running like this continually. I'm worried it's a hacked version of crond. My system was compromised a few weeks ago, and someone tried a brute force attack last night. From what I can tell, they didn't get in, but I'm worried. I did get an email from my server saying they gained root access.
Any advice would be extremely helpful. I've checked the cron logs and I don't see anything out of the ordinary. Same with the messages log.
BTW: I'm very new to linux.
TIA!
