An Ontario transit agency says it was in the crosshairs of a North Korean cyberattack earlier this month. The attack was a virus, routed through Russia, that infected computers at Metrolinx, according to a source at the agency who spoke on condition of anonymity. Homeland security adviser Tom Bossert wrote in a Wall Street Journal op-ed last month that North Korea was "directly responsible" for the WannaCry ransomware attack and that Pyongyang would be held accountable for it. American officials have also said that North Korea is responsible for the Sony cyberattack in 2014 that dumped personal information of tens of thousands of current and former workers online. North Korea has denied involvement in both cases.
