Home Depot breach costs credit unions more than $57 million

Last spring’s security breach at home improvement giant Home Depot affected more than 7.2 million credit union cards — including nearly 135,000 in Georgia — at a cost of about $57.4 million, according to a survey by the Credit Union National Association.

The organization said the cost of the breach per card was $8.02, which included reissuing new cards, member notification and account monitoring.

The Home Depot breach was revealed in early September, but had been going on since last spring. The company said the hack netted cyberthieves 56 million credit card numbers, one of the nation’s largest breaches.

The estimated loss to Georgia credit union is estimated at $1.08 million.

CUNA said the breach during last year’s holiday season at retailer Target has cost credit unions nearly $30 million to date.
