Home Depot’s data breach put 56 million customers at risk

Hackers had access to 56 million credit and debit cards when they breached Home Depot’s security system this year, the company said Thursday. The breach was even larger than the attack on Target last year, when 40 million cards were compromised. The company said that thieves had placed malware software on cash registers in Home Depots throughout the U.S. and Canada from April to September. The malware has since been eliminated. The breach will cost the company at least $62 million.
