Google has just discovered an exploit that, without going into technical details of the how-whats, can allow someone to take remote control of the other person’s iPhone. The gate that allows the exploit to take place is reportedly seven glitches in WiFi Broadcom drivers. Exploit only allows to take control of an iPhone 7 with iOS 10.x.
So far Apple has not made an official comment on the issue. I am sure it will be addressed any minute now.
