JPMorgan Chase Issues Data Breach Warning: Customers' Bank Account Numbers and Personal Information Exposed
In a shocking revelation, JPMorgan Chase has issued a warning to its customers regarding a data breach that has exposed sensitive personal and financial information. The bank's filing with the Office of the Maine Attorney General reveals that cybercriminals have breached a law firm that the bank works with, compromising the personal information of 659 customers.
The incident occurred when a shared network drive belonging to JPMorgan Chase's legal services provider, Fried, Frank, Harris, Shriver & Jacobson LLP, was accessed by an unauthorized third party. According to the filing, the data breach happened on October 23rd, 2025, but was not discovered until October 27th, 2025.
JPMorgan Chase is now sending letters to affected customers, alerting them that their personal information may have been compromised. The bank has warned its customers that the breached files included "your name and one or more of the following: account number, Social Security number, passport number and/or other government ID numbers." The files may also have contained contact information.
In an effort to mitigate the damage, JPMorgan Chase is advising its customers to monitor online activity and account statements over the next one to two years for potential incidents of identity theft or unauthorized transactions. Customers are also encouraged to report any suspicious activity immediately.
To further protect affected customers, JPMorgan Chase is offering free credit monitoring services for two years. This product provides superior identity protection support focused on immediate identification and resolution of identity theft.
The data breach serves as a stark reminder of the importance of cybersecurity in today's digital age. As technology advances, so too do the tactics employed by cybercriminals. It is essential that financial institutions prioritize protecting their customers' sensitive information to prevent such incidents from occurring.
