A large data breach at Home Depot has started to trigger fraudulent transactions that are rippling across financial institutions and draining cash from customer bank accounts. The fraudulent transactions are showing up across the U.S. as criminals use stolen card information to buy prepaid cards, electronics and even groceries. Home Depot has said that 56 million cards may have been exposed in a five-month attack on its payment terminals. The size of the Home Depot breach makes the attack significantly larger and lengthier than the 40 million cards that were compromised in the Target hacking that occurred in the three weeks leading up to Christmas last year.
