Muninn + Yggdrasil

Catch phishing pages before blocklists do.

Muninn is a Chrome extension that scans pages as you browse and warns you when something looks off. Yggdrasil is the open threat database where suspicious URLs can be checked, reviewed, and shared.

Free during beta. Create an account to unlock deep scans, URL submissions, and the full Yggdrasil workflow.

How Muninn Works

Quiet by default. Thorough when it matters.

Muninn uses a two-step system to catch phishing pages before they slip by. The automatic scan checks each page in the background as you browse. If something looks suspicious, deep scan takes a closer look at what the page actually looks like.

That gives you a fast first pass on every page and a stronger second opinion when you want to investigate further.

Phishing
