OpticSpy

 

The OpticSpy modules provide a platform to explore, evaluate, and experiment with optical data transmissions. They capture, amplify, and convert optical signals into digital form that can be analyzed or decoded with a computer.

Application Ideas:

  • Search for optical covert channels (methods of exfiltrating data in a way undetectable to the human eye) that may exist within devices
  • Add data transfer functionality to a project
  • Discover Li-Fi, Visible Light Communication (VLC), or other optical networking systems

Demonstrations:

Arduino:

Using an Arduino Uno with external LED to send a secret message via optical covert channel.

Parallax Propeller:

Using the Propeller-based Hackable Electronic Badge to send a secret message via infrared LED. The LCD displays the message being transmitted.

Tomu:

Using Tomu’s red LED to send a secret message via optical covert channel.

TP-link TL-WR841N:

Using the router’s WAN LED to exfiltrate data via optical covert channel. As a proof-of-concept, the payload is loaded onto the device with known administrator credentials.
