Motorists who have pulled up to one of Canada’s Petro-Canada gas stations in the last few days have been greeted by “cash only” signs, as a cyber attack on parent company Suncor Energy has disrupted the company’s payment and loyalty reward systems.
Petro-Canada has about 1,500 gas stations that span most of the country. Suncor Energy is one of the largest synthetic crude producers in Canada. The outage is very likely to cost the company millions of dollars when all is said and done, and some security experts believe there is a link to Russian hackers with a nationalist bent.
