Description

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.

medium pattern for speed

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
