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
