Phishing pages Chrome had blocked by the time we found and confirmed them, March 2026. The other nine were live.

The data

Chrome let this one load. Muninn didn't.

Checks every address

Domain age, lookalike names, the free hosts scammers use. Runs in the background and sends only the address.

Reads the page when you ask

Tap Deep scan in the popup. Muninn screenshots the page, checks whose logo it is and whether the domain matches, then discards the screenshot.

Says why

Every warning names the brand and the reason. One click tells us if we got it wrong.
