Financial services data breaches expose Social Security numbers, bank and investment account numbers, credit information, transaction histories, and other highly sensitive financial data held by banks, credit unions, investment firms, and lenders. These breaches carry a direct and immediate risk of financial fraud, unauthorized account access, and long-term identity theft, since the exposed data often includes exactly what’s needed to open new lines of credit or drain existing accounts. Financial institutions are also frequent targets of third-party vendor breaches, where a breach at a smaller service provider exposes customer data across multiple banks or investment firms at once. Affected individuals may include current and former account holders, loan applicants, and investment clients, regardless of whether they still have an active relationship with the breached institution. This page tracks confirmed data breaches at banks, investment firms, and other financial services companies, including what data was exposed, which companies notified regulators, and what affected individuals can do next to secure their accounts and understand their legal options.
