Why this tool?

Btlejack is a security tool that provides all options to sniff, jam, and hijack Bluetooth Low Energy (BLE) devices. It can be used during security assessments to test the security of devices that use Bluetooth as a communication protocol.

How it works

Btlejack relies on the BBC Micro:Bit hardware with custom firmware. Upon the first use or after firmware updates, the tool will have to (re)program the Micro:Bit device. When the custom firmware is placed, the scanning and testing can be done easily with just a few commands.

Usage and audience

Btlejack is commonly used for Bluetooth security testing, connection hijacking, or security assessment. Target users for this tool are pentesters and security professionals.
