Attify Badge is a hardware security assessment tool created by Attify used to communicate between a PC and an embedded device over various hardware communication protocols. We initially built the device to help us with our IoT device pentests, but soon realized the immense potential of it. 


The Attify Badge uses an FTDI chip allowing it to speak a wide variety of communication protocols and standards such as UART, SPI, I2C, 1-Wire and JTAG. This allows you to interact with any IoT/Embedded device which has one or more hardware communication ports exposed. It supports both 3.3V and 5V which makes it suitable for a large number of target devices. 


You don’t require special hookup wires or cables to use Attify Badge, rather the standard dupont jumper wires (also included with all Attify Badges). Attify Badge has a micro USB port allowing it to be easily connected with your PC with a micro USB cable which is also included when you order an Attify Badge.

You could use the Attify Badge to: 

  • Gain serial root access on the target device using UART communication

  • Get debugging logs, U-Boot access and bootup logs over serial

  • Dump firmware, API keys or other sensitive information stored on the Flash chip over SPI or I2C

  • Write your own custom firmware to the device by Flash write

  • Perform JTAG Debugging using OpenOCD and GDB
