Perhaps you've heard that in iOS 10. 2 bug fixes were fixed. About each of them reported Adam Donenfield - researcher in the field of security iOS and Android. Then he said that the hacking method using kernel bugs will be demonstrated in the summer at the HITBGSEC conference. This is exactly what happened.
When we talk about hacking, it's not about jailbreaking, although the use of vulnerabilities is possible and for this purpose. This is recognized by Adam Donenfield himself. However, he was only able to imagine a way to exploit the vulnerabilities of the kernel of 64-bit devices with the iOS 10 firmware version. 1 and with earlier versions.
Secure yourself with only one capable - to update the operating system in a timely manner. In the case of the kernel vulnerabilities mentioned above, it does not matter how fresh your device is. Vulnerability is in the iPhone 7. Much more important is the actuality of the firmware version.
