What to Do When Your Data Has Been Breached

Many victims of data breaches only learn about the compromise weeks or months after it occurred, often when they notice unauthorised transactions or receive a notification from the affected company. Signs of a breach include unexpected password reset emails you did not initiate, login notifications from unfamiliar locations or devices, unfamiliar transactions on your bank or credit card statements, and accounts being locked due to failed login attempts. Companies are legally required under GDPR to notify affected individuals within 72 hours of discovering a breach, but this only applies to breaches the company is aware of.

Proactive monitoring of breach databases is the most reliable way to know if your data has been exposed.

Act quickly once you learn your data has been compromised. Change the password for the affected account immediately, choosing a strong and unique password you have not used elsewhere. If you used the same password on other accounts, change those as well — this is the most critical step, as credential stuffing attacks will target your other accounts within hours.

Enable two-factor authentication on all affected accounts. Review recent account activity for any unauthorised changes or transactions. If financial information was involved, contact your bank to monitor for fraudulent transactions and consider placing a temporary block on your payment cards.

Document everything for potential fraud claims.

After addressing the immediate threats, take steps to prevent future exposure. Adopt a password manager to generate and store unique passwords for every account, eliminating the risk of credential reuse. Enable two-factor authentication everywhere it is available.

Review and reduce the amount of personal information stored in online accounts — delete saved payment methods you do not regularly use and close accounts you no longer need. Monitor your credit report regularly for signs of identity theft. Consider a credit freeze if sensitive financial information was exposed.

Accept that breaches will continue to occur and build habits that minimise their impact.
