DNSRecon Package Description

DNSRecon provides the ability to perform:

  • Check all NS Records for Zone Transfers
  • Enumerate General DNS Records for a given Domain (MX, SOA, NS, A, AAAA, SPF and TXT)
  • Perform common SRV Record Enumeration. Top Level Domain (TLD) Expansion
  • Check for Wildcard Resolution
  • Brute Force subdomain and host A and AAAA records given a domain and a wordlist
  • Perform a PTR Record lookup for a given IP Range or CIDR
  • Check a DNS Server Cached records for A, AAAA and CNAME Records provided a list of host records in a text file to check
  • Enumerate Common mDNS records in the Local Network Enumerate Hosts and Subdomains using Google

dnsrecon – A powerful DNS enumeration script
[email protected]:~# dnsrecon -h
Version: 0.8.7
Usage: dnsrecon.py

Options:
-h, --help Show this help message and exit
-d, --domain Domain to Target for enumeration.
-r, --range IP Range for reverse look-up brute force in formats (first-last)
or in (range/bitmask).
-n, --name_server Domain server to use, if none is given the SOA of the
target will be used
-D, --dictionary Dictionary file of sub-domain and hostnames to use for
brute force.
-f Filter out of Brute Force Domain lookup records that resolve to
the wildcard defined IP Address when saving records.
-t, --type Specify the type of enumeration to perform:
std To Enumerate general record types, enumerates.
SOA, NS, A, AAAA, MX and SRV if AXRF on the
NS Servers fail.

rvl To Reverse Look Up a given CIDR IP range.

brt To Brute force Domains and Hosts using a given
dictionary.

srv To Enumerate common SRV Records for a given

domain.

axfr Test all NS Servers in a domain for misconfigured
zone transfers.

goo Perform Google search for sub-domains and hosts.

snoop To Perform a Cache Snooping against all NS
servers for a given domain, testing all with
file containing the domains, file given with -D
option.

tld Will remove the TLD of given domain and test against
all TLD's registered in IANA

zonewalk Will perform a DNSSEC Zone Walk using NSEC Records.

-a Perform AXFR with the standard enumeration.
-s Perform Reverse Look-up of ipv4 ranges in the SPF Record of the
targeted domain with the standard enumeration.
-g Perform Google enumeration with the standard enumeration.
-w Do deep whois record analysis and reverse look-up of IP
ranges found thru whois when doing standard query.
-z Performs a DNSSEC Zone Walk with the standard enumeration.
--threads Number of threads to use in Range Reverse Look-up, Forward
Look-up Brute force and SRV Record Enumeration
--lifetime Time to wait for a server to response to a query.
--db SQLite 3 file to save found records.
--xml XML File to save found records.
--iw Continua bruteforcing a domain even if a wildcard record resolution is discovered.
-c, --csv Comma separated value file.
-v Show attempts in the bruteforce modes.

dnsrecon Usage Example

Scan a domain (-d example.com), use a dictionary to brute force hostnames (-D /usr/share/wordlists/dnsmap.txt), do a standard scan (-t std), and save the output to a file (–xml dnsrecon.xml):

[email protected]:~# dnsrecon -d example.com -D /usr/share/wordlists/dnsmap.txt -t std --xml dnsrecon.xml
[*] Performing General Enumeration of Domain:
[*] DNSSEC is configured for example.com
[*] DNSKEYs:
