Cyberattack at Canadian Engineering Giant Contracted for Government Military, Power and Transportation Projects.

February 15, 2024


A Canadian engineering giant whose work involves critical military, power and transportation infrastructure across the country has been hit with a ransomware attack. Details about the ransomware attack are scarce, with Black & McDonald refusing even to confirm it happened.

Canada’s defense department confirmed Thursday that its systems were not affected by a ransomware attack on engineering giant Black & McDonald. "Once DCC was informed of the incident, it blocked all incoming emails from Black & McDonald out of an abundance of caution and conducted business by phone or in person," Department of National Defense spokeswoman Jessica Lamirande said in a statement. "Once the contractor restored its email system and informed DCC, email communication resumed."

Black & McDonald also has contracts with the Toronto Transit Commission and Ontario Power Generation — both of which told The Canadian Press they were informed by the company about the ransomware incident.
