US Bank experienced a data breach where personal information of approximately 1.1 million customers was exposed. The incident occurred when an employee at a third-party vendor mistakenly sent a file containing sensitive customer data to an unauthorized recipient. The leaked data included full names, addresses, account numbers, and Social Security numbers. This exposure was a result of human error rather than a direct cyberattack on the bank systems. The company notified affected individuals and regulatory authorities shortly after discovering the mistake.
