Yeah, I've thought about this a lot with the increased popularity of digital modes. Especially those small programs made by one or two people, just as you identified. I mean, I crashed a friend's radio simply by sending him an SMS over DMR (seems like a known issue/limitation with the radio firmware). Even well-established products are susceptible to attacks. No different from any other modern tech I guess :)

I'd like to spend some time digging into radio/tnc firmware for vulnerabilities but that's a bit over my head. I've managed to dump the firmware from my TNC but I haven't found a good way to get it disassembled yet. I've got a partial disassembly, but that's it. Unfortunately, I won't have more time to work on that for a few months.
