seeing the latest (leaked?) Cellebrite info from 2024 Summer- BFU State[Before First Unlock state] after posting on, modernimoPuxelsiPhones on the latest OS, and graphene devices see moto be the hardest to get into.
Anyway- , with computers - this was a solved problem from a technical standpoint- Yes I'm talking Truecrypt then, and today Veracrypt. The Hidden Container feature is impressive- but the Hidden OS feature allows for a truly hidden OS behind the scenes that can't be found at all. However, there's a unfortunate weakness that makes this hard to use today- it's limited to MBR , not UEFI [GPT]systems- so unless you like your computer not being able to have more than 2 Tb - and only 4 partitions (so good luck If you do a lot of stuff from dualbooting to other whatnot) We need a Veracrypt Hidden OS equivalent for UEFI systems that's truly undetectable.(That also will work for Linux and maybemeMac not just Windows as Veracrypt currently does - you can only make the Hidden Volumes on the non Windows versions of VC) There was one project to do it - and there were articles and a black hat presentation on 'Russian Doll Steganogrpahy" for a OS- but it didn't go anywhere from what I can tell, and everyone is now wide open .... Unless you have a MBR system. I also think I've heard UEFI is more easily secured than MBR in general and for the foreseeable future...
