Subdomain3 - A New Generation Of Tool For Discovering Subdomains

Subdomain3 is a new generation of tool , It helps penetration testers to discover more information in a shorter time than other tools.The information includes subdomains, IP, CDN, and so on. Please enjoy it.

Features

• More quick

Three patterns for speed. User can modify the configuration(lib/config.py) file to speed-up.

• CDN support

Determines whether the subdomain uses CDN storage automatically,even though the dict of CDN severs not contain the cname suffix.

• RFC CIDR

Sorting ip and report CIDR(example 1.1.1.1/24) that it not use CDN storage;

• Multi-level subdomain support

Discover more subdomains,example:admin.test.xx.com

• Big dict support

Million of subs support

• Less resource consumption

1 CPU/1GB Memory/1Mbps bandwidth

• More intelligent

Discover the fastest nameserver;The strategy of dynamically adjusting of dict by importing subdomains from other sources;Prevent dns cache pollution;

Getting started

git clone https://github.com/yanxiu0614/subdomain3.git

pip install -r requirement.txt

python2/3 brutedns.py -d tagetdomain -s high -l 5

Usage

Short Form	Long Form	Description
-d	--domain	target domain,for example: baidu.com
-s	--speed	speed,three patterns:fast,medium,low
-l	--level	example: 2:w.baidu.com; 3:w.w.baidu.com;
-f	--file	The list of target domain
-c	--cname	n or y,collect cnames
-ns	--default_dns	n or y
-f1	--sub_file	sub dict
-f2	--next_sub_file	next sub dict
-f3	--other_file	subdomain log from search engine
