Home Depot Inc confirmed on Monday its payment security systems have been breached, a data theft analysts warn could rival Target Corp’s massive breach last year. Home Depot said the data theft could impact its customers in stores across the United States and Canada, but there was no evidence that online customers were affected or debit personal identification numbers (PINs) were compromised. The breach was first reported by security website KrebsOnSecurity almost a week ago. It said the problem could extend back to April and affect all of Home Depot’s 2,200 stores in the United States.
