Bluetooth Hacking and Security MasterClass

Hands-On Attacks, Defenses, and Countermeasures for Bluetooth Systems

What you'll learn
- Understand Bluetooth fundamentals: Classic vs BLE, profiles (HID, A2DP, GATT), pairing, and security models.
- Set up and configure lab environments: Raspberry Pi 5, BlueZ tools, nRF52840, Arduino + NRF24L01, and relevant software.
- Perform basic and advanced scanning/enumeration to fingerprint devices and services.
- Design and run controlled Bluetooth DoS experiments and analyze their impact.
- Use nRF52840 for sniffing, role-emulation, and targeted interception in safe labs.
- Build and demo hardware tests (Arduino + NRF24L01 jammer) inside shielded enclosures.
- Implement mitigations and detection strategies to harden Bluetooth deployments.
- Follow legal, ethical, and safety best practices for offensive testing and responsible disclosure.

Requirements
- USB Bluetooth adapter (at least one)
- NRF24L01 module
- Arduino (Uno/Pro Micro/Leonardo)
- Raspberry Pi 5
- nRF52840 development board
- Watch the Requirements video for further details and exact models/configuration.

Description
Master practical Bluetooth offensive and defensive skills with this hands-on, lab-driven course designed for red-teamers, penetration testers, security researchers, and hardware security enthusiasts. You’ll move from clear foundational theory into realistic, mission-oriented exercises that mirror real engagement workflows:recon –>weaponized –> execute –>document –> remediate.

The course begins with a concise introduction and a requirements checklist so you can prepare your lab (Raspberry Pi 5,USB Bluetooth adapters,nRF52840,Arduino + NRF24L01, and test mobile devices). Next we cover core theory — the key differences between Bluetooth Classic and BLE and the security implications of each — so you understand how attacks map to protocol specifics.

Practical modules include:•Basic & Advanced Scanning:learn adapter capabilities, perform passive and active scans, fingerprint devices and services, and use the RPI-5 default dongle for repeatable captures.•Jamming & RF Interference:safe demonstrations of NRF24L01 jammers, step-by-step Arduino builds (with code and Fritzing diagrams), device comparisons, and controlledPortapackmeasurements inside shielded testbeds.•Denial of Service (DoS):protocol-level DoS on BLE and Classic, how L2CAP/ACL floods behave, and how to measure and mitigate impact.•Intercepting Devices:hands-on nRF52840 setup, sniffer role emulation, and practical interception workflows using bluetoothctl and Nordic tooling.•Exploring Real Issues:responsible reproductions of HID and audio vulnerabilities — including CVE-2023-45866, BlueDucky HID techniques, and BlueSpy microphone demonstrations — with defenses and detection strategies taught alongside.•Scenario-Based Attacks & Capstone:full attack chains for Classic and BLE, OPSEC best practices, and a final scenario where you plan and document a professional assessment.

Every module balances offensive techniques with defensive controls, detection strategies, and ethical/legal rules. Labs are non-destructive by default and designed for isolated testbeds; safety checklists and reporting templates are included. By course end you will be able to execute repeatable Bluetooth assessments, construct lab-grade demos, and deliver clear remediation guidance for stakeholders. Prepare your lab, follow the safety rules, and join to gain employer-ready Bluetooth red-team skills.

Who this course is for:
- Red teamers and penetration testers exploring Bluetooth attack surfaces
- Security researchers and ethical hackers focused on wireless security
- Hardware and IoT security enthusiasts
- Cybersecurity students building hands-on RF skills
