URL unicode verifier Firefox

URL unicode verifier

By: Matthew
This plugin checks for potential phishing attacks by analyzing the URL you are visiting for irregularities in the characters encoding.

Features & Capabilities

For any URL containing non-latin character unicode in the domain, a large display banner will alert the user at the top of the page. What I like to call "Deceptive Character Phishing"

This plugin is 100% open-sourced and can be found at: https://github.com/uxai/unicode-verifier

The use case for this is to avoid phishing. These days, scammers have gotten smart and started to register domain names that look the same as your bank, but it may actually be using different character encoding.

The plugin runs in the background and checks the URL of each page you visit. You will never see any popup, and there aren't any settings to set. Let's just hope you never see the warning in the future too. If you do - then leave the page immediately.

Disclaimer: If you visit domains that use characters other than english, the plugin will still flag it, as this is a very simple plugin to flag any top-level non-english website.

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

URL unicode verifier requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
