Home Depot says about 53 million email addresses stolen in breach Fri Nov 7, 2014 6:39am EST (Reuters) - Home Depot Inc, the world's largest home improvement chain, said hackers stole about 53 million email addresses in addition to customer data for 56 million payment cards previously disclosed by the retailer. The company, which confirmed the breach in September, said the files that contained the email addresses did not include passwords, payment card information or other sensitive personal information. Home Depot, which had estimated that the theft would cost about $62 million, was one of a string of U.S. retailers attacked by hackers over the past year. Criminals used a third-party vendor's user name and password to enter the perimeter of its network, Home Depot said in a statement on Thursday. The hackers then acquired "elevated rights" that allowed them to navigate parts of Home Depot's network and to deploy unique, custom-built malware on its self-checkout systems in the U.S. and Canada, according to the company. Home Depot said the stolen credentials did not alone provide direct access to the company's point-of-sale devices. This, however, was "really lipstick on a pig" and the proper solution was to add chip and PIN, or EMV technology, to U.S. credit cards, said David Campbell, chief security officer at SendGrid, a cloud-based email delivery service. Home Depot said it was already rolling out the EMV technology. The company reaffirmed its 2014 sales growth forecast of about 4.8 percent and earnings per share forecast of $4.54. The forecast includes estimates for the cost to investigate the data breach, provide credit monitoring services to its customers as well as legal fees, the company said. I think the big takeaway was that they are able to maintain their sales guidance for the full year, which means people are still showing up at the stores, still spending.. Joseph Feldman, analyst at Telsey Advisory Group, told Reuters. The company maintained that it has not yet estimated the impact of "probable losses" related to the breach. "Those costs may have a material adverse effect on The Home Depot's financial results in the fourth quarter of fiscal 2014 and/or future periods," the company said. Home Depot shares closed up 1.6 percent at $97.29 per share on Thursday on the New York Stock Exchange. Target Corp's unprecedented breach saw hackers steal at least 40 million payment card numbers and 70 million other pieces of customer data in 2013.
