Staff from the Toronto Transit Commission, along with external cybersecurity
experts, continue to investigate and troubleshoot a systemwide ransomware
attack.

The TTC says the personal information of riders and employees is safe, but
service is still being impacted.

Customers will have trouble planning their trips online — ‘next vehicle’
information is unavailable — but there has not been any significant service
disruptions to any TTC routes.

According to the TTC, they experienced loss of their Vision system which is used
to communicate with vehicle operators, forcing them to use a backup radio
system. They also lost vehicle information used to update trip planning apps and
Wheel-Trans bookings were unavailable. Internal email service was also affected.



The transit agency announced it was the victim of the attack on Friday, they say
systems impacted by the attack are still down, and they continue to work to
restore them safely and securely.

TTC officials say they were made aware of “unusual network activity” on Thursday
night and by midday Friday, the hackers “broadened their strike on network
servers”

“This incident did not cause significant service disruptions and there is no
risk to employee or customer safety,” the TTC said in a statement Friday night.

“The full extent of the attack is being looked into and the TTC is working with
law enforcement and cybersecurity experts on this matter.”

While the TTC called it a ransomware attack, they did not say if any demands had
been made.

Ransomware is a form of malicious software that attacks where a company’s data
is encrypted, locking the user out.

As a result of the hack, single-day subway closures which had been planned for a
portion of Line 1 between St. Clair and College stations on Saturday has been
cancelled.

The TTC provides public transit service for up to 1.7 million people per weekday
in Toronto and surrounding municipalities.
