JPMorgan Chase & Co., the biggest U.S. bank, said a previously disclosed data breach of its systems 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 bank information "relating to such users" also was compromised, the company said.
"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.
