Santander, a Spanish bank, reported a data breach affecting customers in Chile, Spain, and Uruguay, as well as some former employees, revealing that a third party gained unauthorized access to a hosted database. Though no financial transaction data or login credentials were compromised, Santander implemented fraud prevention measures. The incident reflects a wider trend of third-party involvement in breaches faced by financial institutions, with examples such as Bank of America, Fidelity Investments, and American Express
The need for businesses to understand their data storage, employ proactive security measures, and assess third-party risks regularly is emphasized. The exact number of affected customers remains unspecified, but Santander assured that regulators, law enforcement, and those impacted are being notified about the breach. ```https://www.darkreading.com/cyberattacks-data-breaches/santander-falls-victim-to-data-breach-involving-third-party-provider
