Other major Canadian banks were not affected by the incident, BMO said the hackers appear to be operating outside of Canada.

“Someone claiming to have the stolen data sent a letter to media outlets across Canada later in the day. The email ended with a sample of the information in question: the names, dates of birth, SIN and account balances of an Ontario man and a woman living in B.C.” reported CBC.

CIBC said, “if any of the clients is a victim of fraud because of this issue, we will return 100 percent of the money lost from the affected bank account.”
