Subdominator

We’re excited to introduce **Subdominator V2.1.0**, featuring bug fixes, new resource integrations, API reworks, and powerful new functionalities, including resource control improvements and a **shell interface** for managing the Subdominator database.

---

🔧 Bug Fixes & Improvements

✅ **Fixed Result Extraction Issue in `quake` Resource**
- A bug affecting **quake** data extraction was identified, leading to incomplete results.
- This issue has been resolved, ensuring more accurate and structured subdomain enumeration.

✅ **Deprecated Non-Functional Resources**
- The following resources have been **removed** due to API deprecation and unavailability:
- ❌ `passivetotal`
- ❌ `columbusapi`

---

🔥 New Resource Integrations

We've added **four new resources** to enhance subdomain enumeration:

- ✅ **odin** – A new reconnaissance API providing extensive DNS footprinting.
- ✅ **digitalyama** – A specialized source for tracking hidden subdomains.
- ✅ **threatcrowd** – An open-source threat intelligence platform for passive DNS data.
- ✅ **hudsonrock** – A threat intelligence service providing deep reconnaissance insights.

These integrations expand **Subdominator's** capabilities, offering **broader subdomain coverage** across multiple intelligence sources.

---

🔄 API Reworks & Migrations

We've **restructured and optimized** multiple existing APIs to improve performance and reliability:

- 🔄 **`merklemap`, `dnsrepo`, and `subdomaincenter`** are now part of **`arpsyndicate`**.
- This **unifies API management** and enhances **data accuracy**, reducing redundancy and improving request efficiency.

---

⚙️ New Features

🚀 **Advanced Resource Control**
- Introduced new **resource control features**, allowing users to selectively enable or disable specific sources dynamically.
- This **improves efficiency**, reducing unnecessary queries and optimizing API usage.

💻 **Shell Interface for Subdominator DB**
- Added a **shell-based interface** to interact with **Subdominator's database**.
- Users can now **view, manage, and manipulate collected data** directly from the command line, making post-processing more convenient.

🚀 **Google Dork-Based Subdomain Enumeration**
- Introduced a **Google Dorking method** for discovering subdomains.
- This feature utilizes **advanced search queries** to extract indexed subdomains from Google search results.
- Helps in **bypassing rate limits** of passive sources and discovering **hidden assets** that might not be available via traditional APIs.

---

📌 Final Thoughts

With these updates, **Subdominator V2.1.0** offers:
✔ More accurate subdomain enumeration
✔ A more reliable and streamlined API setup
✔ Greater flexibility in **resource control**
✔ A powerful **shell interface** for enhanced data management

Upgrade now and explore the latest improvements! 🚀

What's New?

We introduce **Subdominator V2.0.0**, featuring additional minor updates, bug fixes, and significant changes in the `rsecloud` resource handling and `dnsdumpster` API key configuration.

Bug Fixes & Enhancements:

**Resolved Performance Issue in `rsecloud` Resource:**
- A critical performance bug was identified in **Subdominator** where, upon reaching 100% of the API usage limit for `rsecloud`, the tool sent infinite requests due to an unhandled response. This caused severe performance degradation.
- This issue was verified during internal testing and also reported as [Issue 20](https://github.com/RevoltSecurities/Subdominator/issues/20).
- Subdominator V2.0.0 addresses this problem by introducing proper response handling, preventing unnecessary request loops.

`dnsdumpster` Configuration Changes:

Setting up **dnsdumpster** with its API keys has been simplified in this release. Follow these steps to configure it seamlessly:

1. Visit the [dnsdumpster website](https://dnsdumpster.com) and register a new account.
2. After registering, navigate to your account dashboard to find your API key under the [My Account](https://dnsdumpster.com/my-account/) section.
3. Copy your API key(s) and paste them into the YAML configuration file as shown below:

yaml
dnsdumpster:
- z4gi42ifs9asdjbopakwbhorhao0du42po92jkbnkjbsdug082sjbkdhohabdaoiuboadhg
- jdbsaoug0242kjblas42po92jkbnkjbsdug082sjbkdhohabadsjbudaugiuga98t24vi2u


4. Once updated, Subdominator will run smoothly without any exceptions related to `dnsdumpster` API configurations.

With these updates, **Subdominator V2.0.0** ensures better performance, reliability, and ease of use.

- fast and powerfull to enumerate subdomains.
- 50+ passive results to enumerate subdomains.
- configurable API keys setup
- Integrated notification system

Info:
We request existing user to update their config yaml file with new resources by opening the config file in : bash $HOME/.config/Subdominator/provider-config.yaml and add the below resources:

yaml
builwith:
- your-api-key1
- your-api-key2

passivetotal:
- user-mail1:api-key1
- user-mail2:api-key2

trickest:
- your-api-key1
- your-api-key2

by these your config yaml file will get updated or else check your yaml file that matches the below mentioned resources with *, The new users will required to update in next version if any new resources added
in Subdominator.

Usage:
code
subdominator -h
