HostGator says hackers compromised its servers using a previously unknown security hole in cPanel, the control panel software that is widely used by hosting providers. "I can tell you with all accuracy that this is definitely due to a cPanel exploit that provides root access and all cPanel servers are affected," said HostGator system administrator Tim Greer. "This issue affects all versions of cPanel, from what I can tell, from years ago to the current releases, including Stable, Release, Current and Edge."
