Hackers delight
Well, any sensible (intelligent) IT person wouldn't use IoT unless they want to hack other peoples IoT devices !
What chance has security got if manufacturers can't even lock down Internet routers !
And my final words are that once installed, will these IoT devices phone home for security updates, will the owners be aware that their device is an IoT and will do security updates manually if it cannot do them automatically ?
Basically the future is going to be a f**king nightmare, especially with the likes of smart meters and IoT devices !
