The Hidden Risks of Browser Extensions
Browser extensions are powerful tools — but that power comes with access to your browsing data, passwords, and personal information. In 2025, over 30 malicious extensions were found on the Chrome Web Store, collectively affecting millions of users.
Red Flags to Watch For
- Excessive permissions: A weather widget shouldn't need access to "all your data on all websites"
- Unknown developer: No website, no other extensions, no company information
- Too many permissions on install: Legitimate extensions request minimal permissions
- Sudden permission changes: An update that adds new data access after initial install
- Too good to be true: "Free VPN" extensions often sell your data
How to Evaluate an Extension
- Read the permissions list carefully before installing
- Check the developer's identity — website, support email, other extensions
- Read user reviews — especially negative ones mentioning security concerns
- Check if it's open source — verifiable code = trustworthy code
- Look at the update frequency — abandoned extensions may have unpatched vulnerabilities
Why SecureVault's Extension is Different
- ✅ Open source — Full source code available on GitHub
- ✅ Minimal permissions — Only requests what's needed for auto-fill
- ✅ No data collection — Zero telemetry, zero tracking
- ✅ Local encryption — Passwords are decrypted only in your browser
- ✅ Active development — Regular updates by Nafij Rahaman
- ✅ Chrome Manifest V3 — Uses the latest, most secure extension architecture
Best Practices
- Only install extensions from the official Chrome Web Store or verified sources
- Review extension permissions quarterly and remove unused ones
- Use a separate browser profile for sensitive activities (banking)
- Keep your browser updated for the latest security patches
