SAN FRANCISCO - A massive batch of credit and debit card information that went on sale on a criminal internet site Tuesday may be from Home Depot stores and could be linked to hackers previously responsible for breaches at Target and P.F. Chang's, security experts say.
The credit card information was first offered up for sale Tuesday on an underground site that trafficks in stolen financial information, reported security author Brian Krebs on his blog, Krebsonsecurity.com.
Home Depot spokeswoman Paula Drake said she could only "confirm that we're looking into some unusual activity and we are working with our banking partners and law enforcement to investigate."
The data put up for sale was labeled "American Sanctions."
Krebs called the naming "what can only be interpreted as intended retribution for U.S. and European sanctions against Russia for its aggressive actions in Ukraine."
Drake said Home Depot takes protecting customers' information extremely seriously. "We are aggressively gathering facts at this point while working to protect customers. If we confirm that a breach has occurred, we will make sure customers are notified immediately," she said.
