(Yicai Global) May 15 -- Some gas stations owned by China National Petroleum Corp. (CNPC) were hit by the ransomware program WannaCry during the weekend, rendering customers unable to pay the country's largest oil company.
Starting last Friday (May 12), a malware virus that attacks computers has spread quickly across the globe, infecting tens of thousands of computers in nearly 100 countries and regions.
The software encrypts files and demands USD300 worth of Bitcoins be paid as ransom within three days.
Some of its gas stations were affected by the blackmail bug on May 12, CNPC stated on its official website yesterday. The company immediately carried out urgent system maintenance. Its internet connection had been restored to more than 80 percent of its gas stations as of yesterday, and those infected with the virus were starting to take payments again.
