Hathaway_Noa Actually a lot of cops don't know about GrapheneOS, it's just this year that they start to become aware of GrapheneOS because a lot of high end criminals use GrapheneOS as the OS of choice (which makes sense).
I imagine in a worldwide space this is the case, like I said this is just a personal anecdote, some I have known have been aware for 2-3 years but I am in a very tech-focused nation.
Hathaway_Noa Also Cellebrite is really shady when it comes to support for google pixel phones, they mostly keep this information 'classified'.
Cellebrite don't like discussing devices where they have harder efforts with at all, new iPhones also get similar treatment
I mentioned in a comment elsewhere a while ago, but from base UFED they support logical extraction for all Pixels, Filesystem and Physical if rooted.
Hathaway_Noa I know for sure that Premium will roll with support for pixel phones (BF support for BFU and AFU pixels), they probably already offer this service to cops (this is from what I read in their chat channels).
DISCLAIMER (for anyone except Hathaway_Noa ) This is just speculation. I don't want to be the bringer of false hope, so do please take with a grain of salt.
From my own slight educated guess, I would say they could have AFU support in stock... and if they had ever had a BFU it would likely violate forensic integrity and be a extreme last resort. I had an LEO tell me that GrapheneOS was 'a total pain in the ass' at a conference. I mainly make these judgements since I have a UFED myself and I am Cellebrite certified, but I have no access to the other services hence why I said I have no knowledge of their capabilities (I am not a cop).
I don't completely invalidate any theory that it could be worse than what I think though. Pray the 0day lottery is in your favour
