JPMorgan Chase Bank, N.A. has recently disclosed that a technical vulnerability on its online banking site and application led to an unintentional exposure of customer financial details to other customers.

Chase Bank or Chase, is an American national bank headquartered in Manhattan, New York City, that offers more than 5,100 branches and 17,000 ATMs all over the country.

As of 2016, JPMorgan Chase & Co. has 250,355 employees and operates in more than 100 countries.

What Data Has Been Exposed in the Chase Bank Incident?

Apparently, Chase customer’s private information has been seen by other customers starting with May 24th until the issue has been taken care of (July 14th). According to the financial institution, both online banking and mobile app customers have been affected during the incident.

The affected clients allegedly had sensitive information such as names, statements, balance(s), account numbers, and transaction details divulged.

What Happened?

According to BleepingComputer which had seen a copy of the notification regarding the Chase data leakage, the bank declared the issue was caused by a “technology issue”.

We learned of a technical issue here that may have mistakenly allowed another customer with similar personal information to see your account information on chase.com or in the Chase Mobile app or receive your account statements.


The Chase data exposure notice doesn’t provide any details on how a bank member has been able to access other member’s sensitive data but informs there is no evidence that it has been used inappropriately.

Even though there is no evidence of misusing the data, the impacted customers should stay alert and keep an eye on potential phishing attempts.

Also, it is not mentioned whether the incident affected everyone or just a specific category of customers.

What’s Next?

All the affected individuals are currently informed of the incident and encouraged to sign up for free monitoring that will help them notice when there are changes to their credit bureau information.

We are sorry for letting you down and would like to offer you one year of free credit monitoring through Experian’s® IdentityWorks®.


It is not the first time Chase bank experiences an online incident. In 2014, the financial institution disclosed it had suffered a cyberattack in July 2014. The data breach is believed to have exposed information associated with over 83 million accounts being considered one of the largest data breaches ever.
