Cyberattack Against JPMorgan Chase Affects 76 Million Households

A cyberattack this summer on JPMorgan Chase compromised the accounts of 76 million households and seven million small businesses, a tally that dwarfs previous estimates by the bank and puts the intrusion among the largest ever.

The details of the breach–disclosed in a securities filing on Thursday–emerge at a time when consumer confidence in the digital operations of corporate America has already been shaken.

Target, Home Depot and a number of other retailers have sustained major data breaches. But unlike retailers, JPMorgan, as the largest bank in the nation, has financial information in its computer systems that goes beyond customers’ credit card details and potentially includes more sensitive data.
