About Sublist3r2

Sublist3r2 is an improved and bug-free working version of Sublist3r, the original dns enumeration tool but with a much faster bruteforcing routine.

Package Description:

*Sublist3r is a python tool designed to enumerate subdomains of websites using OSINT. It helps penetration testers and bug hunters collect and gather subdomains for the domain they are targeting. Sublist3r enumerates subdomains using many search engines such as Google, Yahoo, Bing, Baidu and Ask. Sublist3r also enumerates subdomains using Netcraft, Virustotal, ThreatCrowd, DNSdumpster and ReverseDNS. (from original page) * "

Compatibility notes:

This particular release is compatible with linux python3 (>3.6) installations only.
Other operating systems (macos, windows) will be supported in later releases.
BruteForcing is now multiple times faster than in the original tool and uses aiodnsbrute instead of subbrute.

Installation

Under linux, use a python3 virtual environment specific to sublist3r.

You will be running the tool within this virtual python environment and not the system wide python installation. All python commands you run once the virtual environment is activated are specific to the virtual environment. Changes you make to a virtual environment, including installing dependencies only affect the virtual environment and do not affect the system wide installation of Python which usually ends up breaking python.

Assuming you are going to keep your python virtual environments in a directory called environments under your home directory, please proceed as follows to install virtual environments , required depencies to run the tool:

1- $ git clone https://github.com/RoninNakomoto/Sublist3r2.git // Download tool from github
2- $ python3 -m venv ~/environments/sublist3r      // create a python version 3 virtual environment for sublist3r
3- $ source ~/environments/sublist3r/bin/activate  // activate sublist3r python environment. 
4- $ python -m pip install --upgrade pip              // update pip inside virtual env.
5- $ cd ~/sublist3r/                                         // switch to your sublist3r download folder.
6- $ pip install -r requirements.txt                    // install sublist3r module dependencies.
7- $ python sublist3r.py -d domain.com               // run sublist3r.py from within activated environment
8- $ deactivate                                            // deactivate environment once done runnning the script.
note: do not use sudo.

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 the results to text file
-h	--help	show the help message and exit

Examples

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

python sublist3r.py -h

• To enumerate subdomains of specific domain:

python sublist3r.py -d example.com

• To enumerate subdomains of specific domain and show only subdomains which have open ports 80 and 443 :

python sublist3r.py -d example.com -p 80,443

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

python sublist3r.py -v -d example.com

• To enumerate subdomains and enable the bruteforce module:

python sublist3r.py -b -d example.com

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

python sublist3r.py -e google,yahoo,virustotal -d example.com

Using Sublist3r as a module in your python scripts

Example

import sublist3r 
subdomains = sublist3r.main(domain, no_threads, savefile, ports, silent, verbose, enable_bruteforce, engines)

The main function will return a set of unique subdomains found by Sublist3r

Function Usage:

• domain: The domain you want to enumerate subdomains of.
• savefile: save the output into text file.
• ports: specify a comma-sperated list of the tcp ports to scan.
• silent: set sublist3r to work in silent mode during the execution (helpful when you don't need a lot of noise).
• verbose: display the found subdomains in real time.
• enable_bruteforce: enable the bruteforce module.
• engines: (Optional) to choose specific engines.

Example to enumerate subdomains of Yahoo.com:

import sublist3r 
subdomains = sublist3r.main('yahoo.com', 40, 'yahoo_subdomains.txt', ports= None, silent=False, verbose= False, enable_bruteforce= False, engines=None)
