This is what security experts have been warning about for 20-25 years. Doesn't look like the facility was compromised, but how long until a refinery, or power plant is successfully attacked. If you're asking yourself "so what?" think about what a disruption in oil production would do to fuel prices, food prices, heating/cooling etc. It wouldn't be pretty!
From Mike Lennon … World's Largest Oil Company Kills Network After Cyber Attack:
Saudi Aramco, Saudi Arabia’s national oil company and the largest in the world, has confirmed that is has been hit by a cyber attack that resulted in malware infecting user workstations, but did not affect other parts of its network.
“On Wednesday, Aug. 15, 2012, an official at Saudi Aramco confirmed that 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,” the company wrote in a statement.
“The disruption was suspected to be the result of a virus that had infected personal workstations without affecting the primary components of the network.”
