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):

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

dnsrecon

DNSRecon is a Python script that 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 Hosts and Subdomains using Google

DNS Enumeration and Scanning Tool

root@kali:~# dnsrecon -h
usage: dnsrecon.py [-h] [-d DOMAIN] [-n NS_SERVER] [-r RANGE] [-D DICTIONARY]
                   [-f] [-a] [-s] [-b] [-y] [-k] [-w] [-z] [--threads THREADS]
                   [--lifetime LIFETIME] [--tcp] [--db DB] [-x XML] [-c CSV]
                   [-j JSON] [--iw] [--disable_check_recursion]
                   [--disable_check_bindversion] [-V] [-v] [-t TYPE]

optional arguments:
  -h, --help            show this help message and exit
  -d DOMAIN, --domain DOMAIN
                        Target domain.
  -n NS_SERVER, --name_server NS_SERVER
                        Domain server to use. If none is given, the SOA of the target will be used. Multiple servers can be specified using a comma separated list.
  -r RANGE, --range RANGE
                        IP range for reverse lookup brute force in formats   (first-last) or in (range/bitmask).
  -D DICTIONARY, --dictionary DICTIONARY
                        Dictionary file of subdomain and hostnames to use for brute force. Filter out of brute force domain lookup, records that resolve to the wildcard defined IP address when saving records.
  -f                    Filter out of brute force domain lookup, records that resolve to the wildcard defined IP address when saving records.
  -a                    Perform AXFR with standard enumeration.
  -s                    Perform a reverse lookup of IPv4 ranges in the SPF record with standard enumeration.
  -b                    Perform Bing enumeration with standard enumeration.
  -y                    Perform Yandex enumeration with standard enumeration.
  -k                    Perform crt.sh enumeration with standard enumeration.
  -w                    Perform deep whois record analysis and reverse lookup of IP ranges found through Whois when doing a standard enumeration.
  -z                    Performs a DNSSEC zone walk with standard enumeration.
  --threads THREADS     Number of threads to use in reverse lookups, forward lookups, brute force and SRV record enumeration.
  --lifetime LIFETIME   Time to wait for a server to respond to a query. default is 3
  --tcp                 Use TCP protocol to make queries.
  --db DB               SQLite 3 file to save found records.
  -x XML, --xml XML     XML file to save found records.
  -c CSV, --csv CSV     Save output to a comma separated value file.
  -j JSON, --json JSON  save output to a JSON file.
  --iw                  Continue brute forcing a domain even if a wildcard record is discovered.
  --disable_check_recursion
                        Disables check for recursion on name servers
  --disable_check_bindversion
                        Disables check for BIND version on name servers
  -V, --version         Show DNSrecon version
  -v, --verbose         Enable verbose
  -t TYPE, --type TYPE  Type of enumeration to perform.
