JPMorgan Chase disclosed this week that the accounts of 83 million households and businesses were compromised during a cyber attack this summer.

It’s the latest development in a string of security breaches that have slammed corporate America over the past year. The cyber hacks have exposed the credit card and personal information of tens of millions of consumers who have shopped or dined at businesses such as Target, Home Depot, Neiman Marcus, P.F. Chang’s and Jimmy John’s.

But the JPMorgan attack was most concerning because, unlike the other companies that were hit, the bank has even more sensitive information, such as consumer’s Social Security numbers.

In a filing with the Securities and Exchange Commission on Thursday, JPMorgan disclosed just how many customers were affected by the breach and what information was compromised.

The bank said 76 million households and 7 million businesses were impacted, which is far more than previous estimates and one of the biggest attacks on record.

But JPMorgan said only customers’ contact information, such as phone numbers, emails, and addresses, was compromised. It said there was no evidence that more sensitive account information, or money, was stolen.
