“Naturally, this feature has sent waves throughout the mobile phone forensics and law enforcement communities, as accessing iPhones may now be substantially harder, with investigators having to rush a seized phone to an unlocking device as quickly as possible.

MacDailyNews Take: Sounds like marketing bluff on the part of Grayshift to us. After all, who’s going to buy boxes from you when they’ll be far less effective in a few months? You can’t brute force if you can’t try a high number of combinations quickly.
Regardless, be sure to use long, alphanumeric passwords and, even if there is a GrayKey box on every corner, your data will remain secure.
Use at least seven characters – even longer is better – and mix numbers, letters, and symbols.
