Apple AirPlay Private Key Exposed

An anonymous reader writes "James Laird has reverse engineered the Airport Express private key and published an open source AirPort Express emulator. 'My girlfriend moved house, and her Airport Express no longer made it with her wireless access point. I figured it'd be easy to find an ApEx emulator — there are several open source apps out there to play to them. However, I was disappointed to find that Apple used a public-key crypto scheme, and there's a private key hiding inside the ApEx. So I took it apart (I still have scars from opening the glued case!), dumped the ROM, and reverse engineered the keys out of it.'"

Everything that needs to read the encrypted content (in this case the airplay device) needs to have the key to decrypt it.

      'Protected stuff sells just fine'.
      'We don't need to worry about little guys stealing our market as the nerds can hack our cheap boxes'.
      'Appeasing content providers is an easy buisness model'

      The problem with hacking is that it's getting easier to protect stuff.
      A decade ago, if you were making a router, you had little choice to make it from a CPU chip, a ROM chip, and a RAM chip.
      All soldered to a board, with comparatively accessible traces.

      Ok - worst case, you needed to desolder the flash, and it was really annoying to do.

      There is almost no way to protect keys in this beyond the 'normal' code obfuscation methods.

      Now, increasingly security architecture is moving on-chip, and becoming cheap. Partially as a
      side-effect of making devices more flexible.
      Many or even most small 32 bit chips now have a small area of ROM that handles the initial boot,
      and some user-settable one-time writable memory.

      Because it's 'free' (a K or two), these often now include routines that will let the user on initial flash
      (or in production of the a large number of chips) say 'only boot from a bootloader with key authenticated
      by the in-ROM key'

      To get to this key is practically very hard - especially if the vendor has taken measures - covering the few
      bytes of ROM in question with metalisation - to prevent this.
      You can't get at it with a soldering iron.
      You can't often now even get at the off-'chip' RAM or ROM easily now, as it's not on seperate chips, it's on
      chips laminated to the CPU.

      Geohot - for example - did nothing at all clever cryptographically.
      He exploited a basic bug in the implementation that is the sort of thing you get when someone reads the
      manpage on a crypto function, and implements it, not really understanding all of the twiddly bits, and leaving
      some out.

      Getting crypto right with modern chips is getting increasingly easy - it is not more expensive or needing more
      hardware to get it right, it simply needs employing someone with a clue to look over your code.
      Drop 20K on http://www.schneier.com/ - for example - or basically anyone that's actually understood crypto,
      and is not just writing it as a 'normal' program.

    how do we choose what gets made

    By either making it yourself, or by purchasing something made by someone else only when it fits all your particular requirements.

    how do we make it, who gets to make it and who gets access to what has been made?

    If you truly value freedom, and not just freedom for you and those who agree with your particular worldview, you don't 'choose' those things. You allow people to be free to make whatever they like however they like and you react to those choices as above.

    Apple's products are Apple's right up to the point where they sell them to you. If they choose to not make the source code for their software available and sell it only as a compiled version, that is their choice. If they choose to offer only their own means on installing additional software, their choice.

    To argue they should be obligated differently is fine with me, but to cloak that under the guise of promoting 'freedom' is not.

  31. Getting iTunes to talk to remote speakers by martijnd · · Score: 4, Informative

    From: http://www.cocoadev.com/index.pl?AirTunesEncryption

    The Apple-Challenge / Apple-Response is iTunes' method to verify that it's talking to an Airport Express; it may be similar to the DAAP one which has been reverse-engineered. These headers are optional when talking to the Airport Express, so it's possible for other programs to talk to the Express but it'll be difficult to get iTunes to talk to something other than the Airport Express.

    Until we get the private key out of the AirPortExpress, it's not possible to convince iTunes to send anything to a non-AirPortExpress client (say, another computer pretending to be an AirPortExpress).

    Seems that problem has now been solved.

    By "streaming music" I mean that it has an audio-out port: you can plug it directly into a stereo and play the music from your computer (or other wireless device on the local network) to your stereo. Most wireless routers don't do that: you usually need some additional piece of equipment to bridge from the network to your audio gear (e.g. a Sonos player). Also, the bit about wireless printing also isn't facile: the Airport Express has a built-in print server and a USB port for connecting printers to it. There are other wireless routers with that feature, but it is hardly universal. So in addition to being a fine wireless router for slinging bits around the aether it also has some very useful network-to-real-world features that make it more useful than a commodity router. And, when the Airport Express first came out 5-6 six years ago, this combination of features was unique in a wireless router, particularly at that price point.

If you're really willing to test your dogma at the risk of prosecution or lawsuit, good for you.

    (This has got to be a dumb question, but once someone answers it, I think I'll start to understand how the Airport is special.)

    Not dumb. You're assuming it's just some sort of wireless router or access point. It does more.

    It has audio out and a USB connector. Audio out can be connected to speakers, so you can take music that you're listening to on your iPod and say, play this in the Living Room. The airport express in the living room can then start playing your audio to the hi-fi. I'm not sure if you can do it from the iPad, but paying from iTunes you should also be able to play multiroom audio if you have several Airport Express.

    Similarly you can print to a printer attached by USB to an airport express.

Now that it's broken, there is a new "analog hole" for audio and video content. It is easy to imagine a computer using this to create a digital media file rather than routing to speakers. I suspect it won't be long before content providers pressure Apple into using secondary data to confirm iTunes is talking to a legit device.

      You can't stream video to an AirPort Express, so there's no new analog hole for video content.
      Even with protected audio content, you could still burn this to a CD as Red Book CDDA audio, which you could then freely "Rip, Mix, Burn" so it hasn't really enabled anything new for audio either.

      What it does allow for is replacing a dead AirPort Express with something more reliable. Those little fuckers (earlier models at least) had a very bad habit of just randomly dying, and usually after a bit more than one year old, conveniently out of warranty. The fault was 200V rated capacitors used in the power supply that were fine in a 110V supply area but eventually died when on 240V...
