What should affected users do?
In general, affected users should:
Change Your Passwords: Immediately update your passwords for all online accounts, especially those associated with your American Express card. Make sure the new passwords are strong and unique, not previously used on any other platform.
Reset Passwords for Other Accounts: If you've used the same or similar passwords for other online accounts, reset those as well. This is crucial as attackers often try using stolen passwords on multiple sites.
Enable Two-Factor Authentication (2FA): Activate 2FA on your American Express account and other important online accounts to significantly reduce the risk of unauthorized access.
Monitor Your Accounts: Regularly review your American Express account and other financial accounts for suspicious activity and report any unauthorized charges immediately.
