What should users do when their data is leaked online?

Here are some data protection measures you can take if you discover your account information has been leaked online.

Users need to take various measures to protect their personal data.

• Change your password as soon as possible . Check all websites that use the same password. Use a trusted password manager to enhance security.
• Be wary of potential scams . Reputable services typically notify their users via email about a major data breach. However, be cautious of phishing scams, as cybercriminals may insert a link in the email prompting users to change their passwords.
• Choose a provider responsibly . If you're considering using an online service like a VPN, take the time to read about the provider. Research the company's expertise and development experience, and if possible, look for reviews of their service from independent, reputable organizations like AV-Test, which provide comprehensive and thorough analysis. Choosing a trustworthy company will ensure your data is secure and protected from potential leaks.
• Don't forget two-factor authentication . Set up 2FA to protect your account from unauthorized access. This can be done by receiving confirmation via SMS, email, or using an authentication app that generates a one-time code. After activation, remember to save the provided recovery code. Avoid taking screenshots of these codes on your phone, as there is a risk an attacker could access the information.
• Block and reissue your bank card if necessary . If payment information is stored by a service that has experienced a data breach (this can be verified by checking the service's Privacy Policy) and confirmation data has been leaked (this can be verified with the service's technical support), block your card immediately and request a reissue to enhance security. Use a third-party service to securely store your card information.

Furthermore, to minimize the risk of future data leaks, always use a VPN. This will obfuscate the digital footprint by providing an IP address from a different country. Additionally, encrypting data before sending will prevent a Man-in-the-Middle attack; communication over an encrypted channel is always better than using plain text.
