The company said its fiscal third quarter sales , including sales in September , are on plan . Additional guidance is provided below . Investigation Details The investigation into a possible breach began on Tuesday morning , September 2 , immediately after The Home Depot received reports from its banking partners and law enforcement that criminals may have breached its systems . Since then , the companys IT security team has been working around the clock with leading IT security firms , its banking partners and the Secret Service to rapidly gather facts , resolve the problem and provide information to customers . The companys ongoing investigation has determined the following : Criminals used unique , custom - built malware to evade detection . The malware had not been seen previously in other attacks , according to Home Depots security partners . The cyber - attack is estimated to have put payment card information at risk for approximately 56 million unique payment cards . The malware is believed to have been present between April and September 2014 . To protect customer data until the malware was eliminated , any terminals identified with malware were taken out of service , and the company quickly put in place other security enhancements . The hackers method of entry has been closed off , the malware has been eliminated from the companys systems , and the company has rolled out enhanced encryption of payment data to all U.S. stores . -more- _ -2- There is no evidence that debit PIN numbers were compromised or that the breach has impacted stores in Mexico or customers who shopped online at HomeDepot.com or HomeDepot.ca .

From the time this investigation began , our guiding principle has been to put our customers first , and we will continue to do so . Payment Security Enhancements The companys new payment security protection locks down payment data through enhanced encryption , which takes raw payment card information and scrambles it to make it unreadable and virtually useless to hackers . Home Depots new encryption technology , provided by Voltage Security , Inc. , has been tested and validated by two independent IT security firms . The encryption project was launched in January 2014 . The rollout was completed in all U.S. stores on Saturday , September 13 , 2014 . The rollout to Canadian stores will be completed by early 2015 . EMV Chip and PIN technology , which began rolling out in early 2013 and already exists in Canadian stores , will be deployed to all U.S. stores by the end of the year , well ahead of a 2015 deadline established by the payments industry . These projects required writing tens of thousands of lines of new software code and deploying nearly 85,000 new pin pads to stores . Updated Guidance Based on its fiscal third quarter results to date , the company confirmed its previous fiscal 2014 sales growth guidance of approximately 4.8 percent . The company also revised its fiscal 2014 diluted earnings - per - share growth guidance and expects that fiscal 2014 diluted earnings per share will grow by 21 percent to approximately $ 4.54 , versus the companys prior guidance of _ $ 4.52 . The companys fiscal 2014 diluted earnings - per - share guidance includes estimates for the cost to investigate the data breach , provide credit monitoring services to its customers , increase call center staffing , and pay legal and professional services , all of which are expensed as incurred in a gross amount of approximately $ 62 million , partially offset by a $ 27 million receivable for costs the company believes are reimbursable and probable of recovery under its insurance coverage .
