Users need to take various measures to protect personal data.

  • Change your password as soon as possible . Check all sites that have the same password. Use a reliable password manager for added security.
  • Beware of potential scams . Reputable services will typically notify their users via email about a major data breach. However, be wary of phishing scams, as cybercriminals may include a link in the email asking users to change their passwords.
  • Choose a provider responsibly . If you are considering using an online service such as a VPN, take the time to read up on the provider. Research the company’s expertise and development experience, and if possible, look for reviews of their service from reputable, independent organizations such as AV-Test, which provide comprehensive and thorough analysis. Choosing a trustworthy company will ensure that your data is safe 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 authenticator app that generates one-time codes. Once enabled, remember to save the recovery code provided. Avoid taking screenshots of these codes on your phone, as there is a risk that attackers could access the information.
  • Lock the card and reissue the bank card if necessary . If payment information is stored by a service that has experienced a data breach (this can be confirmed by checking the service's Privacy Policy) and authentication data has been leaked (this can be verified with the service's technical support), immediately lock the card and request a reissue for added security. Use a third-party service to securely transfer card information.

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