Any security breach anywhere is a problem, but the one outlined below, about the Grayshift iPhone unlocking tool used by many law agencies, seems to be smoke and no fire.
“Source code” later is mentioned to be UI code to access the machine. And likely to be web code based on the commentary, so really its perhaps HTML, Javascript or PHP. Certainly it is unlikely to be the guts of the machine.
I think the Grayshift tool has a limited life as, when Apple finally fix the exploit they’re using, it will become a brick. And it will get fixed, either deliberately or inadvertently.
So, whilst the box is a challenge for iPhone users who may be in breach of the law, the rest of us are still likely to be relatively safe, for now.
