American Express has issued a data breach alert to its users and has notified regulatory authorities. The incident originated from a third-party service provider responsible for handling credit card transactions between buyers and sellers. Their system was compromised by hackers, resulting in unauthorized access and the subsequent leakage of account information for some American Express card members. However, American Express emphasizes that its own systems have not been affected by this incident.
The leaked information is known to include American Express card account numbers, user names, and details such as expiration dates. The exact number of affected users is currently unknown. American Express is actively monitoring these accounts for fraudulent activities and advises users to regularly log into their accounts to review statements, especially over the next 12 to 24 months.
Regarding any fraudulent charges resulting from the data breach, American Express assures users that they will not be held responsible for any associated costs. They also recommend users activate the notification feature in the American Express mobile app to receive real-time fraud alerts and purchase notifications.
