Credit card issuer Capital One has disclosed details of a recent security breach impacting approximately 100 million customers across North America, including six million in Canada.
Capital One, who issue several Mastercard credit cards in Canada including a Costco-exclusive Mastercard and the Hudson’s Bay Rewards Mastercard, discovered the breach on July 19 following an internal investigation that uncovered a security vulnerability that allowed an individual to gain unauthorized access to their customer database on March 22 and 23. The perpetrator has since been arrested by the FBI.
In their statement, the company notes that customers who applied for a Capital One credit card between 2005 and early-2019 may be affected, with a lengthy list of potentially leaked personal information including:
- Names, addresses, postal codes, phone numbers, email addresses, dates of birth and income
- Customer status data including credit scores, credit limits, account balances and payment history
- Fragments of transaction data spanning 23 days in 2016, 2017 and 2018
- Approximately one million Canadian Social Insurance Numbers
All affected customers will be notified through numerous channels and offered free credit monitoring services and identity theft protection.
Capital One notes credit card numbers and online log-in credentials were not compromised during the incident and believe the stolen data was not disseminated or used for fraud by the perpetrator.
The company is advising customers to be vigilant of any suspicious activity on their account and be wary of fraudulent emails. Concerned customers can contact Capital One directly at 1-833-727-1234 or check the dedicated website for more information and updates about the incident.
