Databreach at Montreal Car-Sharing Service Communauto

April 6, 2023


Communauto, the Montreal-based car-sharing service, confirmed on Friday that its computer systems were hit with a cyber attack. The attack compromised the personal information of some of its clients, including member numbers, names as well as email and civic addresses. The cyber hackers couldn’t get their hands on user passwords and credit card numbers.

In a letter sent to subscribers, the president and CEO of Communauto, Benoît Robert, explains that the company managed to obtain “reasonable assurance that the data to which [les cyberpirates] could have had access ”were destroyed. This attack “paralyzed many of our activities and explains some delays in the management of accounts payable and invoicing”, he indicated. The investigation is continuing to determine more precisely what data was stolen.
