Change passwords and privacy settings: Immediately change the passwords of all related accounts, including mobile phones, email, and cloud services, and enable two-factor authentication to increase security. At the same time, check and adjust privacy settings to ensure that sensitive information such as address books is no longer accessed by unauthorized applications.

Notify Contacts: Inform contacts in your address book that your information may have been compromised and alert them to potential fraudulent messages or phone calls from your name.

Call the police and record evidence: If the leak is serious, involves property damage or harassment, call the police immediately. At the same time, keep all communication records, screenshots and other evidence related to the leak.

Avoid further losses: Be careful not to click on links or download attachments from unknown sources to prevent malware from further stealing information or causing financial losses.

2. In-depth analysis of the causes of leaks

Address book leaks are often closely related to the following reasons:

Unsafe apps and permission settings: Some apps ask for too many permissions during installation, including reading your address book. If the user authorizes it without screening, these applications may upload address book information to the server or use it for inappropriate purposes.

Phishing and Fraud: By forging official emails, text messages or websites to induce users to provide personal information, including address book data.

System Vulnerabilities and Hacking: Even the most secure systems can have vulnerabilities that hackers can exploit to steal user data. Additionally, weak passwords or systems that are not updated are also vulnerable.

Physical loss or theft: Loss or theft of mobile phones, computers and other devices may also cause address book information to fall into the hands of criminals.

3. Long-term preventive measures

In order to prevent the address book from being leaked again, we need to take the following long-term preventive measures:

Strengthen application review and permission management: Read user reviews and privacy policies carefully before downloading apps, and only install reputable apps. At the same time, regularly check the permission settings of installed applications to ensure that there are no unnecessary authorizations.

Improve personal information security awareness: Do not disclose personal information easily, especially in a public network environment. Learn to recognize phishing and scammers to avoid falling for them.

Regularly update systems and software: Update operating systems and software applications promptly to fix known security vulnerabilities.

Use security tools and encryption: Use antivirus software, firewalls, and other tools to protect device security. For particularly sensitive information, encryption technology can be used for additional protection.

Back up important data: Back up your contacts and other important data regularly, just in case. When backing up, be sure to choose a safe and reliable storage method and service provider.
