JPMorgan, America's biggest bank, has been a victim to a major data breach, affecting millions.

76m households and seven million small businesses may have had their private data compromised by the cyber attack which gathered accounts holders' names and addresses.

The attack targeted users of the websites Chase.com and JPMorganOnline, and the apps ChaseMobile and JPMorgan Mobile.

However, JPMorgan insisted that information such as account and social security numbers had not been stolen.

In a filing to the US Securities and Exchange Commission, the bank said:

User contact information - name, address, phone number and email address - and internal JPMorgan Chase information relating to such users have been compromised.

However, 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.

As of such date, the firm continues not to have seen any unusual customer fraud related to this incident.

In August the company drafted in the FBI to investigate the cyber attack.

US President Barack Obama reportedly has a JPMorgan credit card, but the bank won't disclose whether his information was stolen.
