Zero-Day Phishing Detector - Chrome Extension

Zero-Day Phishing Detector is a Chrome extension that adds a proactive layer of protection against phishing—especially “zero-day” scams that haven’t yet been cataloged by traditional blocklists or signature-based tools. Instead of relying only on known malicious URLs, the extension uses machine learning to evaluate the pages you visit and spot suspicious patterns in real time.

As you browse, it automatically analyzes website content and behavior in the background. This can include signals such as page structure, form and login prompts, visual and linguistic cues often used in impersonation, and other indicators that a site may be attempting to trick you into revealing passwords, payment details, or other sensitive information. When the model detects a high-risk page, the extension warns you so you can leave before interacting with it.

The goal is to help catch sophisticated phishing attempts that are designed to look legitimate and may bypass common security measures. By focusing on how a site behaves and presents itself—not just whether it’s already known to be malicious—Zero-Day Phishing Detector aims to reduce the window of exposure between the emergence of a new phishing campaign and the time it takes for conventional defenses to recognize it.

Using it is simple: install the extension and browse as usual. It works automatically, scanning pages in real time and alerting you to potential threats. As with any detection system, results may occasionally include false positives, but the intent is to provide early warning and safer browsing against fast-moving phishing attacks.

This browser extension uses machine learning to detect zero-day phishing attacks in real-time. It analyzes website content and behavior to identify potential threats that traditional security measures might miss. By leveraging advanced algorithms, the extension provides an extra layer of protection against sophisticated phishing attempts, safeguarding users from malicious websites designed to steal sensitive information.
