iPhone’s can yield more info now with Checkm8. This is an exploit intended for iPhone X and earlier which gets a TON of info that we were not able to get before, and not everyone is using an XR, XS or 11. Yet. Industrial strength forensic apps like Cellebrite have employed its use.
A pre-Checkm8 analysis on Cellebrite on a test iPhone yielded 8.5GB of recovered data; but using Checkm8, we saw a recovery of 36GB! So, even more deleted chats, emails and other items are recoverable now!
