How do blocklists detect phishing URLs?

Blocklists aggregate **phishing** URL reports from: security researchers, automated crawlers, user reports, and threat intelligence partnerships. Confirmed **phishing** URLs are added to lists queried by filters and browsers.

Detection methods include: analyzing URL characteristics (domain age, registration patterns), crawling suspected sites for **phishing** page signatures, monitoring for brand keyword abuse, and tracking known **phishing** kit deployments.

Lists like Google Safe Browsing, PhishTank, and **SURBL** provide real-time feeds. Speed matters: lists must add URLs quickly before they're used and remove them when attacks end to avoid false positives.
