🔥🐕 Firehound Firebase Security Scanner

Automated Firebase security scanner for iOS applications

Firehound downloads iOS apps from the App Store, extracts Firebase configurations, and systematically tests for security misconfigurations across Realtime Database, Firestore, Storage, Functions, and Hosting services.

🚀 Quick Start

Installation

# Install from PyPI  
pip install firehound-scanner

# Or with pipx (recommended for tools)
pipx install firehound-scanner

Prerequisites

Install ipatool for App Store downloads:

# macOS
brew install majd/repo/ipatool

# Linux - download from releases
# https://github.com/majd/ipatool/releases

Setup & Usage

# 1. One-time setup with Apple ID
ipatool auth login --email [email protected]

# 2. Set environment variables
export FIREHOUND_EMAIL='[email protected]'
export FIREHOUND_KEYCHAIN_PASSPHRASE='your_passphrase'
export FIREHOUND_APPLE_ID_PASSWORD='your_password'

# 3. Start scanning!
firehound --search "banking apps" -l 3      # Search and scan
firehound --bundle-id com.example.app       # Scan specific app
firehound --ids-file app-list.txt           # Batch scan
firehound --directory /path/to/app          # Scan extracted app
