Completely Transparent Attack Surface Management: Introducing Inventory 3.0 Workflow

In the world of bug bounty hunting and enterprise security, understanding and managing your attack surface can be the difference between finding a bug or missing it entirely. Keeping a constant eye on your assets ensures that no security vulnerabilities slip through the cracks. This is where Inventory 3.0 takes center stage. It's a straightforward, effective workflow > dataset for your bug hunting and red team arsenal, designed to simplify and enhance your approach to public bug bounty programs and your enterprise exposure.

Attack Surface Management available to everyone

The Inventory 3.0 workflow is designed to monitor over 800 companies for new assets and streamline the asset management of public bug bounty programs. Its primary purpose is to aid bug bounty hunters in getting up to speed with new programs while offering security teams enhanced visibility into their assets. By reducing the noise and load that automated tools often generate, this project aims to provide a holistic, efficient, and comprehensive approach to attack surface management.

The main parts of this dataset are the DNS Records and Web Servers of particular companies.

How it Works?

It consists of two primary workflows: Inventory 3.0 - Targets, and Inventory 3.0. These workflows are designed to offer an organized view of bug bounty program data and facilitate its efficient management. Let's dive deeper to better understand their unique components.

Inventory 3.0 - Targets

The first part of the workflow streamlines the collection and organization of bug bounty program data from multiple sources.

• Data Collection: The workflow begins by fetching data from two key sources: Bounty Targets Data Chaos Public Bug Bounty Programs. These repositories are treasure troves of bug bounty program information.
• Data Transformation: The collected data is then transformed using python scripts. This ensures that the data is formatted consistently, facilitating easier analysis.
• Program Merging: To avoid duplication, programs with identical URLs are merged, presenting a unified view of each bug bounty program and eliminating redundancy.
• Community Program Inclusion: Programs from the community.json file are incorporated into the workflow, enhancing the diversity and coverage of the dataset.
• Final Output: The workflow culminates in the creation of a consolidated JSON file, targets.json, containing all the merged bug bounty program data. This serves as a centralized resource for bug bounty researchers.

Inventory 3.0

Inventory 3.0 consists of several stages, each building on the data gathered from the previous stage, ultimately creating a thorough inventory of your target domains and subdomains.

1. Gathering the Targets

The first step in the workflow starts with identifying the domains that need to be tracked. These domains get extracted from a JSON file, named targets.json. The file contains the list of all companies with their respective domains that will be analyzed.

2. Full Distribution

The file-splitter node you saw in previous section is really important. That is the node that is being propagated to all of the tools in the workflow making it completely distributed and paralelized. This approach helps us to push the results to repository as soon as they are finished, and other machines picking up all of the jobs as they come.

This is also why we call our platform hyperscalable. More machines = faster execution.

2. Passive Enumeration

Following the identification of targets and domains, the workflow goes to passive enumeration. Data is gathered from a multitude of sources, which provide a wide range of potential subdomains. The tools employed in this process include the following:

• subfinder
• vita
• findomain
• mksub
• puredns
• trickest resolvers

3. Active Enumeration

In the next step, the passive enumeration data is used to create a new brute-force wordlist. And it consists in two parts:

• Active Enumeration: Using mksub to generate potential subdomains for root domain.

• Environments: Dsieve discovers environments per subdomain level. It also generates potential subdomains with mksub and the custom wordlist, along with an additional wordlist - level2.txt.

4. Permutations

The results of the active and passive enumeration are merged, and the workflow extracts environments per subdomain level. It uses alterx to generate permutations and resolve these with puredns.

5. Collecting Previous Results

In this step, the workflow utilizes a Python script to fetch all of the previous hostnames.txt. It then uses anew to extract the new hostnames found and zip active, passive, and permutation results per program for repository storage.

6. Reporting

In the last part of the workflow, the workflow uses dnsx to resolve the found hostnames and a python script to generate a dns-report.csv. The newly found domains are marked with [x]. It also uses httpx to gather information on web servers and generate a server-report.csv. These reports are then finally pushed to the repository.
