“A highly sophisticated cyber attack — known as Advanced Persistent Threat or APT — forced Oak Ridge National Laboratory to shut down all Internet access and email systems over the weekend.
Those restrictions will remain in place until lab officials and others investigating the attack are sure the situation is well controlled and manageable, ORNL Director Thom Mason said today.
Mason said he expects that email functions may be restored Tuesday on a limited basis, with no attachments allowed and restrictions on length. He said he couldn’t speculate on when Internet access will be restored fully, even though the shutdown limits many of the lab’s functions.”
