Cyber-security experts say a massive security breach at the Home Depot could be bigger than the one at Target earlier this year.

WISN 12 News has learned potentially every Home Depot in the country could be included in the hack.

Alex Holden, chief information security officer for Hold Security, which recently discovered more than a billion passwords had been compromised, said the breach may have started in late April or early May.

He and his colleagues said the same group of Russian and Ukrainian hackers suspected in the Target breach is behind the one at the Home Depot.

More than 40 million credit and debit cards were stolen late last year from Target stores.

Holden said the possible data breach at the Home Depot could be larger, and there's evidence the stolen information is already for sale on the black market.

"People should be taking a very close look at their credit card statement because if any fraudulent charges would appear to be on those cards -- maybe immediately or maybe over time," Holden said.

The Home Depot issued a statement Tuesday saying, "Protecting our customers' information is something we take extremely seriously, and we are aggressively gathering facts at this point while working to protect customers."
