Saudi Aramco computer network attacked by virus, operations unaffected

By JACOB GRONHOLT-PEDERSEN

DHAHRAN, Saudi Arabia — A serious computer virus that late Wednesday forced the world’s largest oil producer, Saudi Arabian Oil Co., to isolate all its electronic systems from outside access left the company’s operations unaffected, the company said Thursday morning.

“The company has isolated all its electronic systems from outside access as an early precautionary measure that was taken following a sudden disruption that affected some of the sectors of its electronic network,” Saudi Aramco said in a statement.

“The interruption has had no impact whatsoever on any of the company’s production operations,” it said.

The disruption is suspected to be the result of a virus that had infected personal workstations without affecting the primary servers and components of Saudi Aramco’s network, the company said.
