Nothing new really…there is always some major security exploit or vulnerability in all smart devices. Not just them, but also hardware level things, like how any computer with an Intel CPU dating dating from last year to 1995, can be “hacked” in some fashion and is not something that can be fixed with a software or firmware update.
At least, if you own a Google Pixel phone, you get the latest updates to the Android OS as soon as possible…while the millions of other users on other brand phones, most of them are running much older out of date software with plenty more of well known and un patched security vulnerabilities.
EDIT: LOLZ. Just after i post this, i see in my daily tech news sites, a new article about a new Security issue discovered with Intel CPUs that can not be fixed…see…always something.
