The cyberattack on JPMorgan Chase & Co., first announced in July, compromised information from 76 million households and 7 million small businesses.

Contact information, including name, address, phone number and e-mail address, as well as internal JPMorgan Chase information about the users, was compromised, the filing said. However the bank said no customer money appears to have been stolen, said USA Today.

JPMorgan 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."

In its SEC filing, JPMorgan said as of Oct. 2 it had not "seen any unusual customer fraud related to this incident," said USA Today.

"The usual advice applies: If you get an e-mail or a call from a JP Morgan rep, feel free to thank them for contacting you and hang up. Customers should always initiate that contact by looking at their credit card or statement for the contact number; you simply can't trust that an incoming call or e-mail is legitimate and not a phishing attempt," said Tod Beardsley, engineering manager with security firm Rapid7.
