commoditized comm models that make them such a dangerous single point of failure?

Yeah, so there was a very recent paper and prior papers already looked at the space of CubeSats and commoditized systems and found a lot of vulnerabilities in these commercial off-the-shelf Units, basically.

And we were thinking there are more subsystems there that people haven't been looking at.

And one of these subsystems was the subsystem responsible for the wireless communication.

And as you imagine, probably that's very important in a satellite because any communication to the satellite needs to go over the subsystem.

And in the beginning, you could assume that this subsystem may just be a dump pipe.

It just takes signals and forwards it.

And you had a talk here at DEF CON yesterday, right? Can you talk a little bit more about what it was about?
