  • Unsubstantiated claims about Cellebrite contradicted by Cellebrite

I read preliminary investigation from Swedish police manage to unlock two Pixel 6a GrapheneOS version 2023030400 was confiscated in turned on mode, Police manage to unlock first Pixel 6a 2023/12/30 and second Pixel 6a 2024/01/15 date according to the preliminary investigation protocols The phones were in the on mode (AFU mode) unlocked but another Pixel 6a in the same case seized in the on mode date 2023/05/01 with GrapheneOS version 2023/05/0100 the Swedish police do not manage to unlock The police used the Cellebrite Physical analyzer version 7.66.0.9 with cable on and Cellebrite UFED

Edit by GrapheneOS: Appears to be a misinterpretation of the documents, which do not refer to GrapheneOS in any way. Cellebrite's official documentation says they can exploit all major Android OEM devices running the stock OS both BFU and AFU, but cannot do a brute force attack to get data from a BFU Pixel 6 or later (implying they can't currently exploit the Titan M2 even for out-of-date devices). Cellebrite's official documentation also says that they cannot exploit GrapheneOS either BFU or AFU unless the patch level is earlier than an unspecific late 2022 patch level.

    I would like to read that so please provide a link to the protocols.

      Rarry Swedish police manage to unlock two Pixel 6a GrapheneOS version 2023030400 was confiscated in turned on mode, Police manage to unlock first Pixel 6a 2023/12/30 and second Pixel 6a 2024/01/15 date according to the preliminary investigation protocols The phones were in the on mode (AFU mode) unlocked but another Pixel 6a in the same case seized in the on mode date 2023/05/01 with GrapheneOS version 2023/05/0100 the Swedish police do not manage to unlock

      I don't understand. "AFU" does not mean "unlocked", and if a phone is unlocked why does it take time to unlock it?

          AFU refers to After First Unlock.
          BFU means Before First Unlock where your data is still fully encrypted at rest.

              Aeon I think they know that and were pointing it out to the other person, because the article seems to equate AFU mode with being unlocked.

                Aeon The post I quoted wrote "(AFU mode) unlocked". If the device captured by the police was AFU and unlocked, then there was no unlocking to be done. If the device was AFU but locked, then "(AFU mode) unlocked" doesn't clearly represent the situation.

                    Aeon That's correct, but AFU does not mean the device is unlocked.

                    de0u Perhaps the report isn't very clear and confuses technical terms.

                        I see. I misunderstood, I apologize :-) My understanding of English is not always 100%

                          Aeon Don't worry it's fine, your previous comment is technically correct.

                            Aeon That's ok! My understanding of English is not always 100%, and theoretically it's my native language. Meanwhile, my understanding of other languages isn't above 20% even on a good day, so I have plenty of opportunities to make mistakes.

                                We will need a source, preferably the documents you are referring to, to be able to discuss this further.

                                  I am not a private investigator and a language specialist. But many among us know what chances are of unlocking a Pixel 6+ in AFU even with 4+ sized PIN. Close to zero. Unless the poor sod chose something easy to guess.
