I recently gave anoher talk about our Iridium research together with schneider at HOPE XI on Jul 24th 2016. The video has been released on livestream here (it's the 4th video down on that page) and apparently also found it's way onto Youtube.
The HOPE Conference doesn't appear to have a dedicated place to upload the slides, so I'll just put them here for now: Iridium Satellite Hacking Slides
Feel free to contact me if you have any questions.
