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.

Note
New function uses a Google custom search API. So if you use a new function, then you have to prepare a API key of Google Custom search.
  • 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.

Index Domain Sub-Domain IP Address Access Status (http) Location (http) Access Status (https) Location (https) Whois records

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
Type Field# Description Example
Required 1 Product Category. CMS
Required 2 Vendor name. drupal
Required 3 Product name. drupal
Optional 4 Version binded with this signature. 8.0
Required 5 Regex of identifying product. .*(X-Generator: Drupal 8).*

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).*
Note
If you want to extract product version, you write two regex groups (the second regex is used for version extraction).

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
Type Field# Description Example
Required 1 Product Category. CMS
Required 2 Vendor name. sixapart
Required 3 Product name. movabletype
Optional 4 Version binded with this signature. *
Required 5 Explore path /readme.html
Optional 6 Regex of to confirm product. .*(Movable Type).*
Optional 7 Regex of identifying version. (v=([0-9]+[\.0-9]*[\.0-9]*))

CMS@sixapart@movabletype@*@/readme.html@.*(Movable Type).*@(v=([0-9]+[\.0-9]*[\.0-9]*))@0
Note
If you want to extract product version, you write two regex groups (the second regex is used for version extraction).
Note
If GyoiThon cannot confirm the product by just Explore path, you need to indicate the Regex of to confirm product field. GyoiThon accesses the URL that Explore path and examines the HTTP response using Regex of to confirm product. If this regex matches, GyoiThon judges that the product exists.

signature_search_query.txt

This is Google Custom Search query for identification of product in Google Hacking mode.
If you want to add new query, you have to write it such following format.

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

CMS@sixapart@movabletype@*@inurl:/readme.html@.*(Movable Type).*@(v=([0-9]+[\.0-9]*[\.0-9]*))@0
*@*@*@*@filetype:bak@*@*@0
Note
If you want to extract product version, you write two regex groups (the second regex is used for version extraction).
Note
If GyoiThon cannot confirm the product by just Google Custom Search query, you need to indicate the Regex of to confirm product field. GyoiThon accesses the URL included in the execution result of Google Custom Search API and examines the HTTP response using Regex of to confirm product. If this regex matches, GyoiThon judges that the product exists.

signature_comment.txt

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

Format: field1
Type Field# Description
Required 1 Regex of unnecessary comment.
