CDN PLAN

Hello,my friend,I am very happy that the tool can help you. Now ,I need your help, and for this tool can be more efficient and easy to use.I suggest that you set cdn(command) is y when you use the tool ,and send the file(/result/cname.txt) to me(email:yanxiu0614@gmail.com).I promise that the cnames will be used to enrich dict of cdn_servers in this project. Besides,QQ Group of Tencent:681595202. Thank you!

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 by searching list of CDN severs.

  • RFC CIDR

Sorting ip and report CIDR(example 1.1.1.1/24)

  • 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

The strategy of dynamically adjusting of dic by importing subdomains from other sorces,suppport;

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:baidu.com; 3:world.baidu.com;
-f --file The list of target domain
-c --cdn n or y,collect cnames

Thanks:
