Arsenal Labs at Black Hat 2022

Hello Factoria Labs readers! As you may know, Black Hat USA happened earlier this month in Las Vegas. As well as teaching an in-person SDR class, I was also honored to present a hands-on project at the Arsenal Labs – we had a great turnout, as you can see from the picture.

My project was an end-to-end, RF reversal of a simple garage door protocol. Although the signal produced by the garage door remote was not terribly complicated, the project provided a full view of the reversing process, including:

  • scanning for the remote’s signal
  • capturing the signal to disk
  • tuning and demodulating to produce a digital baseband waveform
  • identifying the framing and encoding of the baseband waveform and then extracting the bits
  • building a simple transmitter to implement the reversed protocol
  • building a more complex transmitter to implement brute force attacks

If you caught my presentation and wanted to look at starter and solution projects, it’s all at:

I’ve also included a PDF of the printed handout we had for Arsenal attendees.

If you’re curious, the garage door remote used in the lab was this model:

Thanks for reading!

    Empty, this model …
    But the rest is good 😉

      Weird. Not sure why the preview didn’t work, but it’s fixed now. Thanks for letting me know.
