Chase Bank has admitted to the presence of a technical bug on its online banking website and app that allowed accidental leakage of customer banking information to other customers.
New York City-based JPMorgan Chase Bank is a financial services giant with a $120 billion annual revenue and over 250,000 employees worldwide.
Personal details of Chase bank customers including statements, transaction list, names, and account numbers were potentially exposed to other Chase banking members.
The issue is believed to have lasted between May 24th and July 14th this year, and impacted both online banking and Chase Mobile app customers who shared similar information.
In a copy of the data incident notice seen by BleepingComputer, shown below, Chase blamed a "technical issue" for this mishap.
"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," states the notice.
