2012, a particularly malevolent virus, Shamoon, struck oil and gas services across Qatar, the UAE and, in particular, Saudi Arabia. The hard disks of more than 30,000 computers were rendered inoperable.21 The attack wiped out the drilling and production data of the Saudi state oil company Aramco, and hit its offices in Europe, the US and Asia. It took the company almost two weeks to restore its network.
I'll be willing to wager those targets are under persistent attack, given what we now know about what oil companies knew in the 70s
