    Depends if he can apply what he learned on how it encrypts to make software that will do it I guess. But I always love seeing these stories, learn something new every time.

    Interesting...

    Having cracked one chip, does that mean he has cracked the entire TPM system, or just that particular model of chip, or just that individual chip? If the latter, not much to worry about; if the entire platform is now compromised, however, it's time to retire it.

    So basically, providing you don't store nuclear secrets on your PC, TPM will continue to be sufficient for your needs.

    If someone manages to gain physical access to machine, take apart the TPM chip, and use a logic probe to digitally eavesdrop, I'd say they are more the welcome to the data on my machine...

    Not to sound too negative but, you guys could have done a little research on something as big as this is instead of adding to the sensationalism of it. A little more research would have revealed some more specifics, like that he had to use an electron microscope to pull this hack off.

    BTW this news broke sometime last week... http://mcpmag.com/articles/2010/02/03/black-hat-engineer-cracks-tpm-chip.aspx

    I thought this was just assumed since the inception of the TPM chip. When i first learned about it, i was told that it could be cracked with physical access to the chip. This same concept applies with encryption. Your stuff might be safe from digital access but a cold boot attack can retrieve encryption keys. We are putting so much focus of the digital aspects of security that we forget about physical access. Put the freakn thing a steel valut and for the love of God man lock the door. Problem solved.

    I'm not sure why this is really news. Yes, obviously, if you're going to go to the lengths of etching the casing off the thing and firing a logic analyser at it, then yes, you can find out what it does and how it does so.

    I'm sure this was indeed assumed since the inception of the TPM chip. All systems like this, from DVD to Blu-Ray to whatever else, where you need to let the person decode the content, are ultimately open to compromise because you must give the user both the encoded material and the means to decode it. The people who design these systems know this. What they're interested in is keeping the amount of compromises down to a bare minimum.

    What's important is that this only really has to be done once in order to produce devices you could either piggyback on top of a compatible device, or produce a replacement device, and circumvent the entire floor show. And it has now been done once.

    do you know safes can be cracked (in america for example they all have those stupied flat keys like you get on padlocks and you just get a bump key (done a key to nearly every home in america)(this is just a guess as i have never been to america and have never seen one, only ever heard about it

    picking locks is just down the alley from this. some of the computer hackers are also gifted lock pickers.

    Indeed. Some of MIT's best are now picking locks, too.

    Hire gordan freeman, master chief, and nomad in conjunction with the safe. Now it is fool proof.

    it maybe a very hard hack to redo but now that he has access to the chip the reverse engineering of the chip can begin to find easier ways of hacking it

    awe. You had my hopes up. TPM is a vile platform and I've longed for it's demise since before the first chips were produced...

    But unless this physical hack can somehow lead to a software hack, then it's only use is if you happen to come into possession of a computer you're sure has valuable secrets.

    I rather ask who's on charge of that server, kidnap the guy and punch the heck out of him til he gives me the codes.

    I asure you is a faster and more effective method :)
