Re: Apple products
The iPhone and iPad have remote activation built-in. Only someone who has “jailbroken” it AND replaced the “spy” code is protected. A stock iPhone or iPad is not safe. (Of course, neither is an iMac or MacBook.)
Most people who jailbreak iPhones do not understand they would need to change the root password.
Only on a jailbroken iPhone would anyone have that possibility - which is why no one should ever jailbreak their iPhone.
