New function!!

The new GyoiThon (version 0.0.4) can list up your subdomain facing on the internet. And if the subdomain is published as a Web service, then GyoiThon executes a health check that a non-destructive vulnerability assessment.

• ex) Listing up your subdomain.
  First, you have to prepare the domain_list.csv is following:

"Domain Name"
mbsd.jp

And you execute following command.

root@kali:~/GyoiThon# python3 gyoithon.py -i --domain_list

As a result, you get a list of sundomains associated with the specified domain.

• ex) Listing up your subdomain and executing health check.
  GyoiThon executes a list up your subdomain and if the subdomain is published as a Web service (with port 80 or 443 open), then GyoiThon execute a health check that a non-destructive vulnerability assessment.

root@kali:~/GyoiThon# python3 gyoithon.py -i --domain_list --through_health_check --safety

As a result, you get a list of subdomains and assessment report.

Overview

GyoiThon is Intelligence Gathering tool for Web Server.

GyoiThon execute remote access to target Web server and identifies product operated on the server such as CMS, Web server software, Framework, Programming Language etc,. And, it can execute exploit modules to identified products using Metasploit. GyoiThon fully automatically execute above action.

GyoiThon's main features are following.

• Remote access/Fully automatic
  GyoiThon can fully automatically gather the information of target Web server using only remote access. You only execute GyoiThon once for your operation.

• Non-destructive test
  GyoiThon can gather information of target Web server using only normally access.
  But, when you use a part of option, GyoiThon execute abnormally access such as sending exploit modules.

• Gathering various information
  GyoiThon has various intelligence gathering engines such as Web crawler, Google Custom Search API, Censys, explorer of default contents, examination of cloud services etc,. By analyze gathered information using strings pattern matching and machine learning, GyoiThon can identify product/version/CVE number operated on the target web server, unnecceary html comments/debug messages, login page etc,.

• Examination of real vulnerability
  GyoiThon can execute exploit modules to identified products using Metasploit.
  As a result, it can examine real vulnerability of target web server.

Preparation.

1. Edit target file host.txt.
   You have to write target web server to the host.txt.
   Writting format is protocol FQDN(or IP address) Port Crawling_root_path.

• Example.

https gyoithon.example.com 443 /

If you want to indicate multiple target information, you have to write below.

https gyoithon.example.com 443 /
http 192.168.220.129 80 /vicnum/

1. Gathering of HTTP responses by Web crawling.
2. Identification of product/version using string pattern matching.
3. Examination of CVE number (from NVD) for identified products.
4. Examination of unneccesary HTML/JavaScript comments.
5. Examination of unneccesary debug messages.
6. Examination of login pages.

• Crawling setting
  GyoiThon uses Scrapy that Python's library.
  By change the parameters in config.ini, you can change setting of Scrapy.

• Examination speed setting
  The examination number and HTTP response size greatly affect examination times.
  By change the parameters in config.ini, you can adjust examination speed.

2. Examination of cloud services mode.

root@kali:~/GyoiThon# python3 gyoithon.py -s

Tips

1. How to manually add new signature (string matching patterns).

signatures path includes below files.

root@kali:~/GyoiThon/signatures/ ls
signature_product.txt
signature_default_content.txt
signature_search_query.txt
signature_comment.txt
signature_error.txt
signature_page_type_from_url.txt

signature_product.txt

This is string matching patterns for identification of product in default mode.
If you want to add new string matching pattern, you have to write it such following format.

Format: field1@field2@field3@field4@field5

If you don't need optional field, you must set * to this field.

• Example

CMS@wordpress@wordpress@*@.*(WordPress ([0-9]+[\.0-9]*[\.0-9]*)).*
CMS@drupal@[email protected]@.*(X-Generator: Drupal 8).*

signature_default_content.txt

This is string matching patterns for identification of product in Exploration of default contents mode.
If you want to add new string matching pattern, you have to write it such following format.

Format: field1@field2@field3@field4@field5@field6@field7@field8

If you don't need optional field, you must set * to this field.

• Example

Web@apache@http_server@*@/server-status@*@Version:.*(Apache/([0-9]+[\.0-9]*[\.0-9]*))@0
CMS@sixapart@movabletype@*@/readme.html@.*(Movable Type).*@(v=([0-9]+[\.0-9]*[\.0-9]*))@0

signature_search_query.txt

This is Google Custom Search query for identification of product in Google Hacking mode.
