TTC investigating ransomware attack that compromised multiple servers

The Toronto Transit Commission says it is investigating a ransomware attack that knocked down some of its communications system and affected a number of its services Friday.

In a statement issued Friday evening, the TTC said they first became aware of the attack Thursday when an IT employee discovered that there was an "unusual network activity."

The TTC said the impact of the hack was initially "minimal," but mid-Friday, "hackers broadened their strike on network servers."

"We discovered it late yesterday afternoon, late evening. And then today, it really, really became quite apparent. A number of our servers were compromised," TTC spokesperson Stuart Green told CP24.

"Right now, our priority is on securing our system. And then we'll figure out how it all happened and to make sure it doesn't happen again."
