Turbolist3r : Subdomain Enumeration Tool With Analysis Features For Discovered Domains

Turbolist3r is a fork of the sublist3r subdomain discovery tool. In addition to the original OSINT capabilties of sublist3r, turbolist3r automates some analysis of the results, with a focus on subdomain takeover.

Turbolist3r queries public DNS servers for each discovered subdomain. If the subdomain exists (i.e. the resolver replied with an address), the answer is categorized as CNAME or A record. By examining A records, it is possible to discover potential penetration testing targets for a given domain. Likewise, the process of looking for subdomain takeovers is simple; view the discovered CNAME records and investigate any that point to applicable cloud services.

Please do not use for illegal purposes.

Usage

Short Form	Long Form	Description
-d	–domain	Domain name to enumerate subdomains of
-b	–bruteforce	Enable the subbrute bruteforce module
-p	–ports	Scan the found subdomains against specific tcp ports
-v	–verbose	Enable the verbose mode and display results in realtime
-t	–threads	Number of threads to use for subbrute bruteforce
-e	–engines	Specify a comma-separated list of search engines
-o	–output	Save discovered domain names to specified text file
-h	–help	show the help message and exit
-a	–analyze	Do reverse DNS analysis and output results
(none)	–saverdns	Save reverse DNS analysis to specified file
(none)	–inputfile	Read domains from specified file, and use them for analysis
(none)	–debug	Print debug information during the analysis module (-a). Prints mostly raw DNS data, familarity with the DIG Linux DNS utility and it’s output is helpful to interpret the debug output
-r	–resolvers	File with DNS servers to populate as resolvers. File must have only one server IP address per line and only IP addresses are accepted
-q	–quiet	Only print found domains and/or CNAME mappings. Note errors may be printed as well

Examples

To list all the basic options and switches use -h switch:

python turbolist3r.py -h

To enumerate subdomains of a specific domain, perform advanced analysis, and save the analysis to a file:

python turbolist3r.py -d example.com -a –saverdns analysis_file.txt

Read subdomains from a file and perform advanced analysis on them:

python turbolist3r.py -d example.com -a –inputfile subdomains.txt

Using -r to populate DNS resolvers from a file (resolvers used with -a analysis module):

python turbolist3r.py -d example.com -a –inputfile subdomains.txt -r dns_servers.txt

To enumerate subdomains of specific domain:

python turbolist3r.py -d example.com

To enumerate subdomains of specific domain and save discovered subdomains to a file:

python turbolist3r.py -d example.com -o example_hosts.txt

To enumerate subdomains of specific domain and show the results in realtime:

python turbolist3r.py -v -d example.com

To enumerate subdomains and enable the bruteforce module:

python turbolist3r.py -b -d example.com

To enumerate subdomains and use specific engines such Google, Yahoo and Virustotal engines

python turbolist3r.py -e google,yahoo,virustotal -d example.com

Dependencies

Turbolist3r depends on the dnslib, requests, and argparse python modules. The subbrute module is required for bruteforce capability, but Turbolist3r should run without it as long as you don’t invoke bruteforce. Submit a PR or contact me if you have issues.

dnslib Module

The dnslib module can be downloaded from https://bitbucket.org/paulc/dnslib/ or installed on many systems using:

pip install dnslib

Requests Module
