Home Depot said that 56 million debit and credit cards are estimated to have been breached in a data theft between April and September at its stores in the U.S. and Canada. 

Home Depot also confirmed that the malware used in the data breach has been eliminated. It said there was no evidence that debit PIN numbers were compromised or that the breach affected stores in Mexico or customers who shopped online at Homedepot.com. It said it has also completed a "major" payment security project that provides enhanced encryption of customers' payment data in the company's U.S. stores.
