AI URL Safety & Phishing Checker
Inspect unfamiliar links before clicking. Detect typosquatting, obfuscated IP addresses, dangerous top-level domains, and credential-harvesting phishing markers.
How Phishing Detection & URL Heuristics Work
Cybercriminals frequently craft malicious URLs designed to deceive victims into divulging sensitive passwords, session tokens, or financial credentials. Modern phishing attacks utilize Typosquatting (registering common misspellings of popular domains like paypa1.com or micros0ft.com), IDN Homograph attacks (swapping Latin characters for identical Cyrillic glyphs), nested subdomains (e.g. bank.com.secure-login-portal.xyz), and open redirect chains. Our scanner evaluates over 20 structural features in real-time to compute an objective security risk score.
🔤 Homograph & Typosquatting Check
Detects deceptive Unicode Punycode characters (RFC 3492) that disguise fake phishing domains as legitimate banking or social media websites.
🌐 Subdomain & Path Obfuscation
Analyzes excessive subdomain depth, IP-literal addresses in hostnames (e.g. http://192.168.1.1/login), and credential keywords in URL query strings.
⚠️ Suspicious TLD & Entropy Scoring
Calculates Shannon entropy to flag randomly generated Domain Generation Algorithm (DGA) hostnames commonly deployed by malware command-and-control servers.
Frequently Asked Questions (FAQs)
Does checking a link here visit or activate the malicious URL?
No. The analyzer performs purely static lexical analysis on the URL string itself. Your browser does not fetch, execute JavaScript from, or download payload files from the inspected address.
What should I do if a URL receives a "High Risk" rating?
Do not click the link, download attachments, or enter any personal credentials. If received via email or SMS, report the message as spam/phishing to your mail provider.
Does an HTTPS link guarantee a website is safe?
No! An HTTPS padlock only guarantees encryption between your device and the server. Today, over 80% of phishing sites utilize free SSL certificates (e.g. Let's Encrypt) to appear legitimate.
