What should you do if you suspect your personal data has been compromised?

Changing your passwords immediately is essential when you suspect your personal data has been compromised because it helps to secure your accounts and prevent unauthorized access. By updating your passwords, you can minimize the risk of further breaches and protect sensitive information. Passwords serve as the first line of defense against cyber threats, and making sure they are strong and current is crucial to maintaining your online security. This immediate action also limits the time cybercriminals may have to misuse your information, as many attacks are executed swiftly once they gain access.

The other options do not provide the necessary immediate protection needed in this situation. Ignoring the issue could lead to greater damage, notifying friends doesn't directly mitigate risks to your accounts, and waiting for further instructions can leave your data vulnerable for longer than necessary. Taking proactive steps, such as changing passwords, is a fundamental principle of cybersecurity hygiene.
