The hacker group AnonGhost announced that it would target Saudi-Kuwaiti oil companies on June 20, 2014 because of their affiliation with Israeli companies. The hackers plan to target companies in the U.S., Canada, England, Israel, China, Italy, France, Russia, and Germany, as well as Qatari government websites.
AnonGhost said the attack was “because petrol is sold with the dollar ($) and Saudi Arabia has betrayed Muslims with their cooperation. So why isn’t Petrol sold with the currency of the country which exports it?”
