Simplii not yet confirmed the data breach, the investigation still in progress and it continues to notify affected clients “through all channels” if it is determined they have been compromised.

We took steps immediately when the incident occurred and we are confident that exposures identified related to customer data have been closed off. We have notified and are working with relevant authorities as we continue to assess the situation,” BMO said in a statement.

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.”
