The Toronto Transit Commission has been hit with a ransomware attack, it said in a statement on Friday. The TTC says the attack by hackers on its computer systems began Thursday night and expanded on Friday.
Stuart Green, a TTC spokesman, says the attack has not caused any significant disruption to transit service and the public and employees are not at risk.
Green says transit vehicles continue to service their routes but apps and computer displays of route information are being affected.
He says there is no estimated time for when services that have been affected will be restored.
