Ok, to be fair, to get access to these IoT devices, your attackers need to have compromised the network already to get into them? Or they have to compromise the supply chain, or compromise apps or widgets that can run on the device, or… There are many ways to get access to these devices.
It is not feasible, in fact not even possible, to replace all CPUs in all devices. It would be too costly, besides the success rate for unsoldering and resoldering pin-throughs in multi-layer boards will never be 100%. In the real world, people will keep their existing devices until those devices reach the end of their lifecycles. So for years to come, people will have households with vulnerable devices.
Do you know how many IoT devices you have on your local network? Probably not. There may even be some devices you have never realized are there in your household at all. Why not try ESET Internet Security or ESET Smart Security, with the updated Connected Home Monitor, which will help you identify all the network-aware devices in your network, and in many cases can identify vulnerabilities in those devices. It will also alert you when a device not previously seen is connecting to your network.
