OWASP Amass

Overview

OWASP Amass performs network mapping of attack surfaces and external asset discovery using open source information gathering and active reconnaissance techniques. It supports dozens of passive data sources (certificate transparency, DNS datasets, APIs) and active techniques (brute force, DNS zone transfers). Amass is the industry standard for comprehensive subdomain enumeration during penetration tests and red team engagements.
