On Monday Home Depot confirmed they had a breach in security and that customer payment data that occur at its stores puts millions of its customers could be at risk of fraud.

Customers who shopped at the home improvement chain in the U.S. and Canada since April may be affected. The retailer said they are working to determine the full scope of the breach but as of now there is no evidence that PIN numbers for debit cards were compromised.

“We want you to know that we have now confirmed that those systems have in fact been breached, which could potentially impact any customer that has used their payment card at our U.S. and Canadian stores, from April forward,” the company said in a statement posted to its website. “We do not have any evidence that the breach has impacted stores in Mexico or customers who shopped online at HomeDepot.com.”

Over the past few months, arts and crafts retail chain Michaels Stores, department store Neiman Marcus, Sally Beauty Supply, and restaurant chain P.F. Chang’s and Dairy Queen revealed they were victims of security breaches aimed at stealing customers’ credit card information.
