⚠️ Important Note Before We Begin
This blog is for educational purposes only — highlighting security tools so you can understand risks and defenses. Misusing hacking tools without permission is illegal and unethical. Always conduct security testing with explicit authorization.
📌 What Is Bluetooth Hacking?
Bluetooth hacking refers to exploiting weaknesses in Bluetooth protocols or implementations to gain unauthorized access, intercept communications, spoof devices, or execute malicious actions.
Common Bluetooth attack types include:
- Eavesdropping — capturing data transmitted between devices
- Bluejacking — sending unsolicited messages
- Bluesnarfing — accessing data without authorization
- Bluetooth Low Energy (BLE) spoofing — impersonating trusted devices
- Man-in-the-Middle (MITM) attacks
The gadgets and tools below help security professionals discover, audit, and exploit these vulnerabilities.
