Frequently asked questions

If you suspect you've been hacked, there are a few signs to look out for:

your email could be sending messages you didn't write,
passwords may change without your knowledge,
unauthorized software might install on your device,
data leak detection tools might show that your personal information is compromised.

Regularly conducting a password leak check can help catch these issues early.

To check if your personal information has been compromised, use a personal data leak checker like Surfshark Alert. These tools scan online databases to see if your information has been exposed. Additionally, monitor your accounts for suspicious activity and change your passwords regularly.

Before deleting a compromised email, run an email leak check to confirm the data leak. If your question, "Has my email been compromised?" is affirmed, consider changing your password and enabling two-factor authentication. Deleting the email account should be a last resort if recovery isn't possible.

Data breaches can expose various types of information, including personal identifiers like your name, address, and phone number; financial details like credit card numbers and bank accounts; login credentials such as usernames and passwords; and sensitive data like social security numbers and medical records.
