Just one day after journalist Brian Krebs broke the story of the liklelihood that many Home Depot stores may have been attacked by hackers, he delivered more bad news for the retail giant and many of its customers.
Based on an in-depth analysis, Krebs uncovered data Wednesday pointing to the fact that there's a 99 percent chance the alleged credit and debit card breach affected all Home Depot stores nationwide.
"Evidence that a major U.S. retailer had been hacked and was leaking card data first surfaced Monday on the cybercrime store rescator[dot]cc, the shop that was principally responsible for selling cards stolen in the Target, Sally Beauty and P.F. Chang’s," Krebs wrote.
A comparison of the ZIP code data between the unique ZIPs represented on Rescator’s site, and those of the Home Depot stores shows a staggering 99.4 percent overlap, Krebs noted on his website.
Although Home Depot has not concluded whether any of its stores has experienced a breach, a message posted Tuesday on the main website says, "We’re looking into some unusual activity that might indicate a possible payment data breach and we’re working with our banking partners and law enforcement to investigate.
"First, you will not be responsible for any possible fraudulent charges. The financial institution that issued your card or Home Depot are responsible for those charges should we confirm a breach."
While many banks have fraud departments and often alert customers to questionable credit and debit card activity, it’s wise to monitor your accounts for transactions that you never made and report any unauthorized charges immediately to your card issuer.
