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 thedomain_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 |
---|---|---|---|---|---|---|---|---|
1 | mbsd.jp | mbsd.jp | ['40.115.251.148'] | 301 | https://www.mbsd.jp/ | 301 | https://www.mbsd.jp/ | *** |
2 | mbsd.jp | www.mbsd.jp | ['40.115.251.148'] | 301 | https://www.mbsd.jp/ | 200 | - | - |
3 | mbsd.jp | www2.mbsd.jp | ['40.115.251.148'] | 301 | https://www.mbsd.jp/ | 200 | - | - |
- 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.
Index | Domain | Sub-Domain | IP Address | Access Status (http) | Location (http) | Access Status (https) | Location (https) | Whois records | Assessment results |

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.
