Ad-Shield Hosts Generator

This repository contains a tool to automatically generate and update a hosts file for blocking Ad-Shield related domains.

Overview

The main script analyzes obfuscated Ad-Shield scripts to extract delivery domains. These domains are then formatted into a standard hosts file structure (0.0.0.0 domain) to be used as a blocklist for advertisements and tracking.

Repository Structure

• index.js: The core logic for domain extraction. It fetches the script, deobfuscates it, traverses the AST to find specific patterns, and outputs the found domains.
• hosts: The generated blocklist file containing the extracted domains.
• .github/workflows/generate.yml: A GitHub Actions workflow that runs periodically to update the hosts file and commit changes automatically.
• package.json: Defines the project dependencies.

Usage

To generate the list locally:

1. Install dependencies:

   npm install

2. Run the script:

   node index.js

Automation

The project includes a GitHub Action (generate.yml) that:

• Runs every hour.
• Executes the generation script.
• Updates and sorts the hosts file.
• Commits and pushes any changes to the repository.
