It's a little hard to distinguish worthwhile warnings from the near-constant din of finger-wagging
http://cs.dartmouth.edu/~vibhu/wireless/PIPExploits.pdf
Basically control frames run in the same band as the payload data, so if you put a ZigBee header half way down your packet and cause some noise, the inside application data turns into a new packet header. You can't do this on 802.11b/g/n/etc because the control data is send out of band from the application layer data.
It's considerably different from the attack mentioned in this post, but we've know at least that the protocol has been broken for years.
In fact: the finger-waggers have been right about this issue since approximately 1988, when Paul Graham's friend shut down much of the Internet with a tiny C program that shouldn't have been possible to write back then, but is in fact still possible to write in 2016.
I'm becoming more and more convinced that nothing is going to change (with regard to overall security in general) until we have some huge event that negatively impacts a large portion of the population in a major way. Until then, things will continue as they are, and security won't be taken seriously.
I'm ready for the 2016 version of the 1988 sendmail worm (or perhaps something with the "average user"-visible impact of the 1990 AT&T crash), just to "get it over with" and get us moving forward.

Fascinating stuff... Thanks for sharing!
Anyone in tech with two braincells to rub together could tell you that security is a hard problem. And yet there has been a consistent pressure in IoT enthusiasm which rested on the premise that security was a solved problem. Everything about IoT went against decades of hard-won wisdom about internet security: lessen your surface area, keep as much stuff off the internet (behind firewalls) as possible, constant vigilance through patching and staying up to date on vulnerabilities is important, use strong credentials to secure anything that could ever be reached from the internet. In short, that internet security was a big and difficult job, and a constant battle that required careful risk management.
IoT enthusiasts dismissed all of that and never had a good counter-argument, just the insistence that nothing, not even security issues, should get in the way of how cool IoT devices could be.
It was obvious that this would be a problem. And every security expert made mention of it. There is no "oops, well how were we to know?" about it.
When attacks can be trivially copied, even obscure security issues can become easily exploitable problems under attack from bulk exploitation tools.
For as many of these REAL security issues we face, there are many stories published that have no real-world impact.
Examples: The story from defcon (or blackhat, cant remember which) about installing ransom-ware on your smart thermostat.
The headlines were all "Hackers make thermostat ransom-ware" or "Your smart thermostat is now vulnerable to ransom-ware"
A few points: - It required local access - It required an SD card reader - It also required the thermostat run a local HTTP server
Another decent example were the SmartThings security holes from earlier this year: - It was mostly an oauth2 authorization issue (applications requesting grant types it didn't need) - The apps were actually independently developed (not ST official) and took some technical knowledge to deploy yourself - The rest were known security issues in the Zigbee protocol that SmartThings has little control over. Similar to this article.
Or the botnet of cameras which is probably the most high-profile example and most relevant are labeled as "The IoT brought down the internet"
That's a lesson for the makers of those cheap DVRs and Cameras, it was also a lesson in user documentation to avoid them doing stupid things. That's the only example in recent years I've seen that goes anywhere, but the problem is it's drowned out by nonsense and clickbait headlines.
