Phishing attacks are one of the most common cyber threats, targeting individuals and organizations worldwide. Our mission is to provide a free, accessible tool that helps users identify malicious URLs before they fall victim to scams.
By combining multiple security databases with advanced heuristic analysis, we aim to provide accurate, real-time protection against phishing attempts.
Database Checks
We query multiple security databases including Google Safe Browsing and our proprietary Phishcheck.org database containing over 54,000 known phishing URLs.
Heuristic Analysis
Our system analyzes URL patterns, checking for suspicious characteristics like:
- Suspicious top-level domains (TLDs)
- IP addresses instead of domain names
- Punycode (internationalized domains used for spoofing)
- Excessive subdomains
- Unusual URL length
- Suspicious keywords in combination with complex domains
- Known URL shortening services
Risk Scoring
Results from all checks are combined to calculate a comprehensive risk score (0-100) and confidence level. This helps you make informed decisions about whether to trust a URL.
While we strive for accuracy, no automated system is perfect. Please keep in mind:
- New phishing sites may not yet be in our databases
- Legitimate sites may occasionally be flagged due to suspicious patterns
- This tool analyzes URLs only - it cannot detect all types of social engineering attacks
- Always use common sense and verify the authenticity of unexpected messages
