This project is for educational purposes only.
All activities described in this documentation should only be carried out in environments where you have explicit permission to conduct testing. Unauthorized access, scanning, or exploitation of Bluetooth devices is illegal and can result in severe penalties. Please ensure you comply with all applicable laws and regulations in your jurisdiction before proceeding.
This documentation provides a comprehensive guide to exploring Bluetooth functionality on various devices (e.g., ECUs, smartwatches, mobile phones), with a focus on reconnaissance and injection activities.
- Setting up and installing necessary tools
- Performing Bluetooth reconnaissance
- Injecting data into target devices
- Executing Denial of Service (DoS) attacks
Bluetooth Classic is a widely used wireless communication protocol for short-range data transmission. It is optimized for higher data throughput and continuous connection, making it ideal for applications that require ongoing data streaming.
- Higher energy consumption compared to Bluetooth Low Energy (BLE).
- Quick connection establishment with continuous communication.
- Supports fewer devices compared to BLE, due to higher power usage.
- Bluetooth Service Scanning and exploitation
- Exploiting the OBject EXchange (OBEX) Service
- Exploiting OBEX - PBAP to fetch Personally Identifiable Information (PII)
- Performing a Denial of Service (DoS) attack
- Implementing CarWhisperer
- Ubertooth tool exploration
- Future scope in Bluetooth testing
To prevent Bluetooth-based attacks, apply the following measures:
-
Secure Pairing
Implement modern pairing methods with passkeys or PIN authentication. -
Service Restrictions
Whitelist only necessary services to limit access to critical ones. -
Data Validation
Ensure data sanitization and validation, and use antivirus software. -
User Awareness
Educate users on the risks of accepting unknown files and emphasize safe Bluetooth practices. -
Rate Limiting
Implement rate-limiting to avoid resource exhaustion attacks. -
Connection Management
Set timeouts for unresponsive connections and blacklist suspicious devices. -
Regular Updates
Keep firmware and software up to date with the latest security patches. -
Traffic Monitoring
Use Intrusion Detection Systems (IDS) to monitor Bluetooth traffic for abnormal activities. -
Enhanced Security
Prefer secure, encrypted profiles and consider Bluetooth Low Energy (BLE) for added security.
- OBEX: For file exchange and exploiting data sharing vulnerabilities.
- CarWhisperer: For intercepting and injecting audio into Bluetooth car kits.
- Ubertooth: A tool for Bluetooth signal capture and analysis.
- BlueToolkit: A framework for scanning and testing Bluetooth vulnerabilities.
