After a data breach, give each account a unique password and enable two-factor authentication if available. Verify notices through the company’s site or known contact details, not message links. For exposed payment data, contact the bank or card issuer directly.
Regularly review bank and credit-card accounts, investigate unfamiliar transactions, and check credit reports for unknown accounts or activity. If payment information was compromised, ask the bank or card issuer whether a new card or account number is needed; transaction alerts can flag purchases. Limit personal details shared publicly and review social-media privacy settings.
Depending on what was exposed, you may consider a fraud alert, which asks businesses to take extra steps to verify identity before extending credit, or a credit freeze, which restricts access to your credit report and makes opening a new account in your name more difficult. Unexpected emails, texts or calls about the breach can still be scams; knowing the affected company’s name does not prove a message is legitimate.
