JPMorgan Chase Says 76 Million Households Affected by Data Breach

JPMorgan Chase disclosed to the SEC that a security breach this summer affects some 76 million households and 7 million small businesses.

Financial giant JPMorgan Chase disclosed to the SEC on Thursday that a security breach this summer' affects some 76 million households and 7 million small businesses, but involves only non-critical information such as phone numbers and email addresses. "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," reads the filing. The company said it has not seen any "unusual customer fraud" related to the breach. Regardless, customers should be on watch for any strange activity in their bank accounts, such as fraudulent login attempts or phishing scams. Government agencies are looking for the perpetrators of the breach and, presumably, any possibility that the company might have failed to properly secure consumers' information. Earlier Thursday, JPMorgan denied reports that it had suffered a second breach.
