    I doubt it. That info is first party and not to be trusted since it is obviously marketing. Any third party article that backs up their claims?

      Isn’t it an open secret that powerful entities (like spying institutions) can get into pretty much every system if they have physical access? Why is this not plausible

          I am aware that there are secure encryptions, but android isn’t hardware encrypted isn’t it? Haven’t used google android for a while, but no encryption was one of the reasons I moved away from it.

          No idea about apple, but longer startup times for storage encryption doesn’t seem like a very apple thing to do

          Also phones are so seldom turned off, and if the system is running storage encryption becomes less of a concern as the key is somewhere in the ram

            For a few years now Android has been encrypting storage. Not the SD card, and maybe not even the internal storage (which on android land means your files that you can access with a file manager without root) but I’m not sure about that part. The app’s main data is surely encrypted though, when the security menu in the settings says so.

            But, there’s a loophole. Or two.
            The parent commenter said, actual encryption can’t be broken without keys.
            First, the keys are in the black box TPM of the phone.
            Second, how do you verify that the phone uses an effective and unmodified encryption algorithm, and also that keys are never leaked anywhere?
            And now consider that popular brands have been bundling malware for years, some of which cannot really be uninstalled either.

              Yeah TPM chip encryption is mostly not secure (at least not by simply existing, as an encryption with with a strong password that only exists in your head is) I’ve seen a german youtuber crack the bitlocker TPM encryption of a windows think pad, I have no doubt big companies can do this for the 3-4 most used TPM chips in android phones

              And if you got the device and can damage it, even if you couldn’t crack the chip, putting the silicia under an electron microscope is always an option (lots of actual manhours of actual experts needed, but you could charge the client heavily to compensate)

                No. The TPM was not cracked. The communication was sniffed, which is unencrypted. This requires a Device to be modified and then successfully unlocked to get exploited also this does not affect devices where the tpm is integrated in the SoC.

                  You are right in a sense of: If the TPM holding the keys were itself encrypted with a strong password, this would be still be considered secure. You are wrong in the sense of: lenovo sells a device, tells its users its encrypted, their data is safe. None can steal their data

                  in reality the data can easily be accessed, which could be considered as “cracking the device/bypassing the encryption” because what lenovo prevent was someone ripping your ssd l, but not just decrypt it because the encryption was not implemented securely.

                  I don’t want to debate the security of a luks Linux volume or veracrypt windows laptop, (even though even those are in theory vulnerable to highly targeted and skilled things like cleverly exploiting e.g the logofail bug)

                  My point isn’t that there are no ways to have a secure system, my point is that the percentage of truly secure systems is low

        No. You watch too many Movies. Yes there were attempts from state sponsored actors to weaken encryption algorithms. But is encryption easy to crack? No.

          Dude what encryption are you talking about? Hardware storage encryption is just by now getting more widely adapted, the phone I used till a year ago didn’t even support any encryption.

          Sure, aes-256 with secure password only stored in your mind is quasi 100℅ safe, but that is not how most devices handle their “encryption”.

          If the key for the encryption is on the device, and either stored in an unencrypted TPM or unencrypted storage, its not a matter if breaking the encryption (quite impossible) but breaking the software/hardware (quite possible for someone with good enough forensics and skilled programmers)

          Also also: encryption only helps if the device is off, which is seldom the case with phones.

            You stated in your original comment: “pretty much every system”. So no, any modern phone if android or iOS is by default encrypted.

            If the key for the encryption is on the device, and either stored in an unencrypted TPM or unencrypted storage, its not a matter if breaking the encryption (quite impossible) but breaking the software/hardware (quite possible for someone with good enough forensics and skilled programmers)

            TPMs are by design encrypted.

            Keys are not stored unencrypted at least not when you encrypt your storage with modern solutions and set it up reasonably. You use either your TPM to store the key or store it on the drive and have it encrypted by itself or use a KDF.

            Also also: encryption only helps if the device is off, which is seldom the case with phones.

            No this assumption is wrong. You still would need to circumvent the Login into the device which is mostly secured by a pin or password or biometrics.

              If you think TPMs are always encrypted, a key can be encrypted “with itself” and still be any use to you and android system pin is secure you are right. Might also believe in santa

                Not sure what you are rambling about the TPM.

                Then prove that the Lockscreen is insecure.

    They imply they have active cracking abilities for all modern phones, that would be neat to see demonstrated.

    It wouldn’t even be hard, just invite third party reporter to bring in a bunch of phones with a capture the flag text file on them. Take each phone one by one behind a screen, break it, bam you don’t have to give away any secrets but you prove that you can break the phone

        That is mostly good enough, a password that does not get cracked if it is generated randomly.

      Why would they do this when they already make millions? The general public isn’t buying their product. They’ll only do private demos.

        There is competition amongst the phone cracking companies. And there’s a limited amount of municipal money available. So they need to differentiate themselves from each other somehow.

        There is good data that celibrite can break every phone out there right now, except for grapheneos… But I’ve heard no such data about this company. This means we can only speculate.

        So if I was a municipality, and I wanted to decide who got my limited budget, I’d want to compare who’s giving me the best value for money. So I would need some metric, some data point, some way to differentiate them. That’s where reporting, would come in. The websites are public for a reason…

          The websites are there to get a phone call. No municipality is spending this kind of money without a 3-quote requirement and demos. (Unless there is a preexisting relationship/renewal)

        I agree they don’t want smartphone security to improve. But they also have to let their customers know which phones they can break.

    Phones are really not that hard to compromise from an encryption standpoint. All they need to do is break a pin most of the time. Also the pin is very predicable and probably can be pulled from a cloud service like google.

    It is actually pretty horrifying to think about

    This looks like old news to me. Years ago I’ve read that three letter agencies can access phones without getting the access code or bio-metrics from the phone owner.

    Lot of cope and denial in these threads. Yes the same-day is probably a rosy estimate based off people using 6 digit codes or something easy to crack, doesn’t mean it’s false or that they can’t hypothetically target longer alpha-numeric passwords. For all we know they might not even be brute-forcing and could be conducting some sort of exploit that over time reveals the encryption keys themselves in some way.

    I’m still very curious about the nature of the mechanisms of action. I assume they manage to bypass the basic lock-out against entering too many passcodes too quickly somehow which is what enables this. If throttling could be properly enforced (to say nothing of something like 10 attempts and it refuses all future attempts and erases the key type of thing) this type of attack wouldn’t be practical for anyone using anything above a 6 digit numerical passcode in any reasonable timeframe. I wonder if they exploit wireless radios including cellular, wifi, bluetooth and force some code on the phones via these usually-on chips that enables this via exploiting problems in their architecture. Perhaps something that locks up, prevents functioning or resets certain checks via flooding parts of the hardware/software from these points of access. Or if it really is purely phy/log access to the lightning/usb-c port.
