NEW YORK (AP) — JPMorgan says data breach affected about 76 million households and 7 million small businesses.

JPMorgan Chase & Co. (JPM), the biggest U.S. bank, said a previously disclosed data breach affected 76 million households and 7 million small businesses.

Customer names, addresses, phone numbers and e-mail addresses were taken, the New York-based bank said today in a regulatory filing. Internal data that identify customers by category, such as whether they are private-bank clients, was also obtained by hackers, said a person briefed on the matter.

The breach affected anyone who visited the company’s websites, including, or used its mobile app, said the person, who requested anonymity because that information wasn’t publicly disclosed. Might be a good time to move your Money out of Chase

“There is no evidence that account information for such affected customers -– account numbers, passwords, user IDs, dates of birth or Social Security numbers –- was compromised during this attack,” the company said. Yeh right that a cover up waiting to happen

The bank, led by Chief Executive Officer Jamie Dimon, hasn’t detected “any unusual customer fraud” related to the breach, and clients aren’t liable for unauthorized transactions that are promptly reported to the company, according to the filing.

JPMorgan had gigabytes of data, including customer-account information, siphoned by hackers in the attack, which lasted months, people familiar with the incident told Bloomberg News in August, shortly after its detection. Investigators in the case tracked stolen files to a Russian data center, the people said.
