retail news in context, analysis with attitude

The Wall Street Journal reports that personal financial data that was stolen from Home Depot by hackers "has started to trigger fraudulent transactions that are rippling across financial institutions and, in some cases, draining cash from customer bank accounts, according to people familiar with the impact of the hacking attack.
The fraudulent transactions are showing up across the U.S. as criminals use stolen card information to buy prepaid cards, electronics and even groceries, these people said. In some cases, the fraudulent transactions have been tracked to batches of cardholder accounts that are tied to specific ZIP Codes, they said.

According to the Journal, "It still is too early to tell how many instances of fraud will eventually be traced to the Home Depot breach. The flood of recent incidents across numerous retailers means that cardholders may have shopped at more than one merchant that had been attacked, making it difficult to decipher which fraudulent transaction is tied to which breach.

And, the Journal writes, "Some large financial institutions … have proactively started reissuing cards to customers whose data were exposed in the Home Depot attack. Other lenders are reissuing cards only when they see fraud attempts.
Representatives of large banks were reluctant to discuss the fallout from the attack, saying they didn't want to appear vulnerable to hackers. A spokesman for Home Depot declined to comment on any fraudulent activity tied to its breach."
