Two major US banks, JPMorgan Chase and TD Bank, experienced data breaches in November 2024 due to unauthorized access by their employees. The incidents resulted in fraudulent transactions and exposure of sensitive customer information in Massachusetts. These events underscore the ongoing challenge of insider security threats within financial institutions. JPMorgan Chase has taken steps like terminating the employee involved and reimbursing affected customers, while TD Bank attributed the breach to an employee accessing customer data without proper justification. The breaches highlight the need for stricter security measures and more robust access controls in the financial sector to prevent similar occurrences from happening again.
