The OWASP Amass Project has developed a tool to help information security professionals perform network mapping of attack surfaces and perform external asset discovery using open source information gathering and active reconnaissance techniques.

Information Gathering Techniques Used:

• DNS: Basic enumeration, Brute forcing (optional), Reverse DNS sweeping, Subdomain name alterations/permutations, Zone transfers (optional)
• Scraping: Ask, Baidu, Bing, DNSDumpster, DNSTable, Dogpile, Exalead, Google, HackerOne, IPv4Info, Netcraft, PTRArchive, Riddler, SiteDossier, ViewDNS, Yahoo
• Certificates: Active pulls (optional), Censys, CertSpotter, Crtsh, Entrust, GoogleCT
• APIs: AlienVault, BinaryEdge, BufferOver, CIRCL, CommonCrawl, DNSDB, GitHub, HackerTarget, IPToASN, Mnemonic, NetworksDB, PassiveTotal, Pastebin, RADb, Robtex, SecurityTrails, ShadowServer, Shodan, Spyse (CertDB & FindSubdomains), Sublist3rAPI, TeamCymru, ThreatCrowd, Twitter, Umbrella, URLScan, VirusTotal, WhoisXML
• Web Archives: ArchiveIt, ArchiveToday, Arquivo, LoCArchive, OpenUKArchive, UKGovArchive, Wayback
