The Rhinelander Home Depot store is part of what may be the biggest credit card theft in history. According to the Milwaukee Journal Sentinel, 7,250 credit and debit card numbers from the Rhinelander store were listed for sale on the black market as of a week ago. The article goes on to say that more than 282,000 cards were stolen statewide.

Home Depot has confirmed that the malware used in the recent breach has been eliminated from its U.S. networks, and they have completed a major payment security project.

According to a Home Depot press release, the company’s investigation has determined that the criminals used custom-built malware to evade detection, something that hasn’t been seen in other attacks. This attack has been estimated to have affected approximately 56 million unique payment cards, between April and September of this year.
