To keep your phone number found on dark web from being exposed in the first place, you should follow some simple precautions. Here’s what we recommend doing if you find your phone number on dark web: 

• Use a VPN: It’s best to use a reliable VPN, such as FastestVPN to conceal your IP address and encrypt your internet traffic. This prevents hackers on public WiFi from intercepting your data and helps protect your browsing activities from trackers.
• Audit Your Public Profiles: Delete sensitive details like your phone number, home address, and email from social media and public directories. Close any old accounts you no longer use.
• Limit Data Sharing: Only share sensitive information, such as your Social Security number or primary phone number, when it is absolutely necessary. Always ask if there is an alternative way to verify your identity.
• Strengthen Privacy Settings: Regularly review and apply the strictest privacy settings on your social media accounts to ensure your information isn’t visible to the general public or data-scraping bots.
• Do Not Click on Suspicious Links: Never click on suspicious links in texts or emails. These are often “phishing” attempts designed to trick you into handing over personal information.
