Some Niagara customers who had photos printed at Walmart are getting emails telling them their financial information may have been breached.
Back in July, Walmart Canada disabled its online Photo Centre website as a precaution, after getting word of a potential security breach.
The company also notified the Office of the Privacy Commissioner of Canada and brought in a third party investigator to see if there was, in fact, a compromise.
The investigation revealed malware installed by a third party that collected credit card and other personal information customers provided when placing an order - such as name, email address and account password.
Now, some customers who had pictures printed through the Photo Centre website between June 2014 and July 2015 are being notified their information may be compromised.
Customers are asked to take a close look at their credit card bills and contact their financial institutions if they suspect any irregular activity.
It is also suggested customers change passwords on other sites or services if it is the same one they used on the Walmart Photo Centre.
