Now On Video: GCHQ Destroying Laptop Full of Snowden Disclosures 237

An anonymous reader writes "On Saturday 20 July 2013, in the basement of the Guardian's office in Kings Cross, London, watched by two GCHQ technicians, Guardian editors destroyed hard drives and memory cards on which encrypted files leaked by Edward Snowden had been stored. This is the first time footage of the event has been released."

        Ignoring the fact that copies exist (and everyone involved knew that), physical destruction is in fact the recommended way to destroy the data on a hard drive, SSD drive, flash memory, etc. etc.

        You can overwrite the drive 50 times and you can not be certain that the data is unrecoverable. If you put a grinder to the drive surface, you can be very certain of that.

        There's a reason the military shreds harddrives when it disposes of them.

          To rephrase: It's relatively easy to ensure that this HDD does not store any data. However it is nearly impossible to ensure that this data is not stored on any HDD.

          You can overwrite the drive 50 times and you can not be certain that the data is unrecoverable.

          That hasn't been true for about 20 years now. Overwrite your data once and it's gone. Even if you don't overwrite it randomly no data recovery group have been shown to be capable of recovering overwritten data even in the face of great monetary incentive.

          There's a reason the military shreds harddrives when it disposes of them.

          Yes but it has nothing to do with data possibly being recoverable. It's entirely to do with removing all doubt if a procedure has been applied. If you look at a drive you have no way of knowing if the data has been wiped or if there's anything recoverable on it. If you look at small shards of what's left of a drive then there's no doubt. It doesn't mean that other methods aren't equally secure, just harder to administrate.

          • Overwrite your data once and it's gone. Even if you don't overwrite it randomly no data recovery group have been shown to be capable of recovering overwritten data

            That's if you want the data to be overwritten and you're the owner of the drive. If you want to delete data on someone else's drive, you would have to ensure that the drive does not have some custom firmware installed that messes with the overwriting process...

          • ... no data recovery group have been shown to be capable of recovering overwritten data even in the face of great monetary incentive.

            How many of those "data recovery groups" have had the resources of a modern industrialized nation state behind them? The scope of what is possible can vary enormously depending on your resources.

          Bullshit. If your drive works fine, even after single (or two, if you are paranoiac) overwrite with random data no-fucking-body in the whole universe will recover anything.

          There's a reason the military shreds harddrives when it disposes of them.

          But for completely different reasons what you think, its because:
          - your drive might be faulty so the overwrite is actually not performed
          - could be faster (overwrite of big disk can take hours)
          - the destruction can be performed by IT-ignorant, non-technical guy
          - the destruction process can be easily CONTROLLED by another non-technical persons.

          This last one is actually main reason: in such process there are usually more people involved which "watch each other".
          However control of soft (data-only) destruction is very difficult: even if all involved people would be highly technically capable (including your commanding officer), It is difficult to assure that the other guy does not use (intentionally or unintentionally) wrong, hacked or faulty software, does not make copy during overwrite, makes proper control read after the process etc ...

              This is where the SECURE ERAS EUNIT ATA command comes in.

              There are only a small number of such replacement 512 byte sectors available. Most drives have not done remapping a significant number of sectors.

              The probability that critically sensitive data just so happens to reside in a remapped sector, is scant at best.

            Partially true, but not entirely.

            True, in modern drives we operate very close to the physical limites and overwriting is a lot more destructive than it used to be.

            However, there are also so many intermediate layers and internal logic (like the relocation of faulty sectors another commenter pointed out) that you'd have to go very low-level to come even close to any assurance that everything actually has been physically overwritten.

          You can overwrite the drive 50 times and you can not be certain that the data is unrecoverable.

          Actually, this is an old myth, which had some truth to it when hard disk weren't operating at the known physical limits. Then you could actually read some erased information by using a more sensitive magnetic head, which was able to tell the difference between a former one overwritten by zero and a former zero overwritten by zero. But this is no longer so. Any reserves that might have been in the magnetic surface of disk are now used to increase information density. The most sensitive reading heads available are those already built into the hard disks. Overwrite a section of the disk with zeros (or ones, whatever you like), and you can be sure that the information formerly there is safely overwritten.

          You can overwrite the drive 50 times and you can not be certain that the data is unrecoverable.

          If you can recover the data overwritten 50 times, then you also can recover the data overwritten 49 times (that is, the first set of data you've overwritten the original data with), the data overwritten 48 times (that is, the second set of data you've overwritten it with), the data overwritten 47 times, the data overwritten 46 times ... and you'd have to be able to distinguish between them. which means that on a 500 gigabyte hard disk, you'd be able to recover 25 terabytes of data. I strongly doubt that this is possible.

          • by Tom ( 822 )

            You misunderstood "it is not 100% guaranteed to be gone" for "it is 100% guaranteed to be recoverable".

            Sure, with each pass you will make some of the data gone for good. But your certainty is a limes function. So no, after x passes you won't be able to recover x * capacity in bytes. But you might be able to recover some of the original data.

    What the hell was that? They threatened to shut down the Guardian if the media wasn't handed over; it appears though that they didn't have the balls to go through with the threat. Instead they came up with this bizarre compromise that involved 'destroying' the data. Why do this? Was it just a way for the government to save face and not have to back down from some crazy ass redline that threw out there? They must know that the files were immediately duplicated and spread around the world. That was by far one of the strangest things I've ever seen a newspaper do.

            I think the NSA got considerable opposition from Google, and knew from the beginning that it would, which is why Google was (per David Drummond) never even asked to provide broad access to user data. The revelation that the NSA might be tapping connections between data centers caused a crash project to make sure all of that traffic was encrypted, for example. In general, this stuff has really pissed Googlers off and Google engineers are working to plug every potential leak they can find.

    A small team of trusted senior reporters examined Snowden's files in a secure fourth-floor room in the Guardian's King's Cross office. The material was kept on four laptops. None had ever been connected to the internet or any other network. There were numerous other security measures, including round-the-clock guards, multiple passwords, and a ban on electronics.

    I remember when everyone was claiming computers would make life easier. LOL! Paperless offices FTW!
    (don't misunderstand; I like computers and networks, but from the beginning, I have always questioned the implementation of them as it occurred...one of the reasons why I don't own a cell phone, and studied networking so I could protect some of my privacy, just as I studied driving a vehicle before driving)

    This may seem like an offtopic rant, but the brainwash mentality is what makes this crap work.

    We have gotten into a mindset from this tactic that makes this shite easier to swallow, because we get used to swallowing shite. We have forgotten how to find out for ourselves, we WANT the 10 second soundbite because we are too busy swallowing the shite, to fit in with our shite swallowing peers.
