Desjardins data breach much larger than first estimated, affecting ALL 4.2 million members

Frédéric Tomesco reports:

All of Mouvement Desjardins’ individual members, 4.2 million people, have had their personal information compromised as a result of the actions of a single employee, who has since been fired, chief executive officer Guy Cormier said Friday. That’s about 56 per cent more than the total that Desjardins first disclosed June 20.

With Sûreté du Québec having informed Desjardins of its findings on Thursday, “it was important for me to inform our members as quickly as possible,” Cormier said Friday morning at a hastily called press conference in Montreal.
