About Muninn - Phishing Protection

Muninn warns you about phishing sites before you enter your password. When you land on a suspicious page, Muninn runs a quick check in the background. If something looks off, you'll see a warning banner. For known phishing sites, Muninn blocks the page entirely and explains why. You can also run a deeper scan on any page if you want a second opinion, or report sketchy sites to help protect others. The extension checks URLs against Yggdrasil, our public phishing database, and uses AI analysis to catch new threats that haven't been reported yet. Works quietly in the background. No configuration needed. Learn more at norn-labs.com/muninn
