The company that suffered the 2014 breach exposing data from about 76 million households was JPMorgan Chase.
The 2014 JPMorgan Chase data breach was disclosed in October of that year. Attackers compromised several of the bank’s servers and accessed information associated with approximately 76 million households and 7 million small businesses.
The stolen information reportedly included names, addresses, telephone numbers, and email addresses. JPMorgan Chase said that the attackers did not obtain account numbers, passwords, Social Security numbers, or birth dates in the intrusion, and the bank found no evidence that customer funds had been taken.
Investigators linked the incident to a compromised employee credential and a failure to use two-factor authentication on one of the affected systems. The episode is often remembered as a large financial theft, but its known impact was primarily exposure of contact and business information rather than direct loss of account balances.
