Study Notes
PhishNet
- PhishNet is a predictive blacklisting scheme used to detect phishing attacks.
- Traditional blacklisting approaches are easily evaded by attackers because they rely on exact matches with blacklisted entries.
- PhishNet utilizes five heuristics: top-level domains, IP address, directory structure, query string, and brand name.
- PhishNet combines blacklisted sites using these heuristics to identify new phishing sites.
- PhishNet employs an approximate matching algorithm to determine if a URL is a phishing site.
- PhishNet has two main components:
- Component I: Predicting malicious URLs.
- Component II: Approximate matching.
