Webcrack Unpack

A TypeScript CLI tool to unpack JavaScript files using webcrack with parallel processing.

Features

- Parallel Processing: Process multiple JavaScript files simultaneously using configurable thread count
- Recursive Scanning: Automatically finds all .js and .min.js files in subdirectories
- Smart Output: Preserves directory structure and renames output files appropriately
- Progress Tracking: Real-time progress updates with colored output
- Error Handling: Comprehensive error handling with detailed logging

Installation

``bash


Install globally via npm

npm install -g webcrack-unpack

Or use with npx (recommended - no installation required)

npx webcrack-unpack [options]

Or install locally in your project

npm install webcrack-unpack
`

Usage

`bash
webcrack-unpack [source_directory] [output_directory] [options]
`

$3

- source_directory - Directory to scan for JS files (default: current directory)
- output_directory - Directory to output unpacked files (default: source_directory/unpacked)

$3

- -s, --source - Source directory to scan for JS files
- -o, --output - Output directory for unpacked files
- -t, --threads - Number of parallel threads (default: number of CPU cores)
- -h, --help - Display help information
- -V, --version - Display version number

$3

`bash


Process current directory, output to ./unpacked, auto threads

webcrack-unpack

Process specific directory, output to ./unpacked

webcrack-unpack /path/to/source

Process with custom output directory and 4 threads

webcrack-unpack /path/to/source /path/to/output --threads 4

Using options instead of positional arguments

webcrack-unpack --source /path/to/source --output /path/to/output --threads 4

Mix positional arguments with options

webcrack-unpack /path/to/source --output /path/to/output -t 8

Use npx without installation

npx webcrack-unpack --source /path/to/source --output /path/to/output -t 8
`

Output

The tool will:

1. Scan the source directory recursively for JavaScript files
2. Process each file using webcrack to deobfuscate and unpack
3. Save results maintaining the original directory structure:
- bundle.json → original_filename.json
- deobfuscated.js → original_filename.js
- Any additional files created by webcrack

Requirements

- Node.js 16.0.0 or higher
- webcrack library (automatically installed as dependency)
