Vsafe - Phishing Link Checker

Check links for phishing signals with local URL and page analysis plus optional reputation lookups.

Vsafe – Phishing Link Checker 🔐 **Browse smarter. Spot suspicious links. Protect your sensitive information.** Vsafe by Digimartrix is a browser security extension that helps you identify suspicious URLs, phishing pages, deceptive login forms, and potentially dangerous website instructions before you trust them. Using local URL analysis, page-level security checks, an optional machine-learning model, and optional external threat reputation services, Vsafe provides understandable warnings to help you make safer browsing decisions. 🛡️ Key Features **🔎 1. Smart URL Analysis** - Detect suspicious and misleading URLs. - Identify look-alike brand domains and potential typo-based impersonation. - Flag shortened links, IP-address login pages, HTTP connections, and suspicious URL structures. - Highlight internationalized domain names that may require closer inspection. **🤖 2. Local Machine-Learning Analysis** - Uses a bundled, offline-trained URL classification model to identify suspicious URL patterns. - Combines model-based insights with deterministic security checks. - Provides advisory signals rather than treating every suspicious pattern as confirmed malicious activity. **🌐 3. Website & Page Security Checks** - Identify suspicious credential forms and unexpected form destinations. - Detect potential brand impersonation and cross-origin password requests. - Flag suspicious recovery-phrase requests and deceptive verification instructions. - Recognize potential fake browser-update lures and suspicious executable downloads. - Inspect supported page frames and open shadow roots within defined resource limits. **🚨 4. Real-Time Security Warnings** - View security indicators directly on the extension toolbar. - Receive in-page warnings with explanations of suspicious signals. - Review findings and recommended actions in the extension popup. - Receive optional desktop notifications for high-risk findings. **🔒 5. Sensitive Form Submission Guard** - Warns when you attempt to submit a sensitive form on a page with high-risk evidence. - Offers an opportunity to leave the page or proceed at your own discretion. - Provides an additional layer of caution before potentially exposing credentials. **⛔ 6. Optional Threat Blocking** - Enable the “Block reported threats” feature to block destinations reported by your configured threat reputation provider. - View a dedicated warning page before deciding whether to return or continue. - Uses browser-level navigation rules for supported blocking scenarios. - Local heuristic and machine-learning findings provide warnings; they do not independently trigger threat blocking. **☁️ 7. Optional External Reputation Checks** Configure a supported provider to check URLs against external threat intelligence: - Google Web Risk - VirusTotal - A compatible custom JSON endpoint Provider availability, API access, and configuration requirements apply. An unavailable lookup is not treated as proof that a website is safe. **📚 8. Security Awareness & Learning** - Understand why a website was flagged. - Review recommended actions and security explanations. - Explore built-in learning content. - Use speech explanations to make security findings easier to understand. **🕘 9. Privacy-Conscious Browsing Tools** - Optional hostname-only browsing history, disabled by default. - Optional local feedback to help review findings. - Light, dark, and system theme options. - Bounded page inspection designed to reduce unnecessary resource usage. 🔐 Privacy Matters Vsafe is designed to keep sensitive browsing information private. - Page text, typed form values, keystrokes, and clipboard contents are not intentionally transmitted to external reputation services. - External URL checks are optional and use the provider you configure. - Optional browsing history stores hostnames rather than complete browsing URLs. - History is suppressed in incognito mode. - Security checks operate
