Power-Grid Cyber Attack Seen Leaving Millions in Dark for Months

A blackout that swept parts of North America in August 2003, leaving 50 million people in the dark for as long as four days, provides a glimpse of the havoc a cyber attack could inflict on the nation’s power grid.

Internet-based terrorists would be capable of causing blackouts “on the order of nine to 18 months” by disabling critical systems such as transformers, said Joe Weiss, managing director of Applied Control Solutions LLC, a Cupertino, California-based security consulting company.
