description = [[ Attempts to retrieve information about the domain name of the target ]] --- -- @usage nmap --script whois-domain.nse -- -- This script starts by querying the whois.iana.org (which is the root of the -- whois servers). Using some patterns the script can determine if the response -- represents a referral to a record hosted elsewhere. If that's the case it will -- query that referral. The script keeps repeating this until the response don't -- match with any of the patterns, meaning that there are no other referrals and -- prints the output. -- -- @output -- PORT STATE SERVICE REASON -- 80/tcp open http syn-ack -- | whois-domain: -- | whois3: Record found at whois.arin.net -- | netrange: 199.19.112.0 - 199.19.119.255 -- | netname: WEBRULON-NETWORK -- | orgname: webRulon, LLC -- | orgid: WL-1 -- | country: US stateprov: NY -- | -- | orgtechname: webRulon Support -- | orgtechemail: support@webrulon.com -- | -- | Domain name record found at whois.enom.com -- | -- | Registration Service Provided By: Namecheap.com -- | Contact: support@namecheap.com -- | Visit: http://namecheap.com -- | Registered through: eNom, Inc. -- | -- | Domain name: random-foo-example.com -- | -- | Registrant Contact: -- | Example -- | John Foo () -- | -- | Fax: -- | Dimosthenous 215 -- | Athens, Attiki 17673 -- | GR -- | -- | Administrative Contact: -- | Example -- | John Foo (john@gmail.com) -- | +30.69425555555 -- | Fax: +1.5555555555 -- | Dimosthenous 215 -- | Athens, Attiki 17673 -- | GR -- | -- | Technical Contact: -- | Example -- | John Foo (john@gmail.com) -- | +30.69425555555 -- | Fax: +1.5555555555 -- | Dimosthenous 215 -- | Athens, Attiki 17673 -- | GR -- | -- | Status: Active -- | -- | Name Servers: -- | dns1.registrar-servers.com -- | dns2.registrar-servers.com -- | dns3.registrar-servers.com -- | dns4.registrar-servers.com -- | dns5.registrar-servers.com -- | -- | Creation date: 14 Oct 2011 13:41:00 -- | Expiration date: 14 Oct 2013 05:41:00 --- author = "George Chatzisofroniou" license = "Same as Nmap--See http://nmap.org/book/man-legal.html" categories = {"discovery", "external", "safe"} local io = require "io" local ipOps = require "ipOps" local math = require "math" local nmap = require "nmap" local os = require "os" local stdnse = require "stdnse" local string = require "string" local table = require "table" hostrule = function( host ) local is_private, err = ipOps.isPrivate( host.ip ) if is_private == nil then stdnse.print_debug( "%s Error in Hostrule: %s.", SCRIPT_NAME, err ) return false end return not is_private end action = function( host ) local mutexes = {} -- If the user has provided a domain name. if host.targetname then local referral_patterns = {"refer:%s*(.-)\n", "Whois%sServer:%s*(.-)\n"} -- Remove www prefix and add a newline. local query_data = string.gsub(host.targetname, "^www%.", "") ..
