In December 2014, Discover Financial Services experienced a data breach reported by the California Office of the Attorney General in March 2018. The incident involved unauthorized exposure of Discover card account information, though the company clarified that its internal systems were not compromised. The exact number of affected individuals and the specific types of data exposed (e.g., card numbers, personal details) remain undisclosed. While the breach did not result in confirmed financial fraud or identity theft, the exposure of payment card data poses risks such as potential misuse for unauthorized transactions or phishing attempts targeting cardholders. The lack of clarity on the scope of the breach further complicates risk assessment for impacted customers. Discover did not report evidence of data being actively stolen or exploited, but the incident underscores vulnerabilities in third-party handling of sensitive financial information.
