I received an e-mail from AT&T telling me my cpanel has been sending out attempts to remote to other computers. I've had modsecurity and cxswatch updated and running on here for over a year and neither caught anything. I also did a scan with rkhunter and configserver exploit scanner and neither came up with anything. My firewall is set to block pretty much anything outbound other than general things like port 80, 443, and so on. Is there any way to tell which account is the culprit as I don't see any unusual activity on any of them but it's hard to go through a couple hundred domains and manually look at the files.
