Johansen Cracks AirPort Express Encryption

womby writes "DVD Jon has just announced that he cracked the encryption in Apple's AirPort Express. 'I've released JustePort, a tool which lets you stream MPEG4 Apple Lossless files to your AirPort Express. The stream is encrypted with AES and the AES key is encrypted with RSA.' No real details of the process employed in cracking the unit but newsworthy none the less."

    Well, a potential abuse of this system could be wardriving with cannibal corpse. If crackers can figure out how to encrypt the songs, they can war drive around till they find an AE and play, "Entrails Ripped From a Virgin's Cunt" instead of the Seasame Street sings the family wanted to play. There are valid reasons to having this encrypted.
    Also, the RIAA probably put some pressure on Apple to encrypt the songs. While I don't like piracy, the thought of someone driving around so they can download music that other people they don't know are listening to is very bizzare.

    To be honest, Apple's products become much more useful (and more desirable to purchase) when people come out with neat hacks like this.

    The only thing that makes it more attractive is that Apple finds a way to close the hole exposed by John's (or his friends') hack and the RIAA continues to let Apple distribute their wares for a reduced price.

    Once Apple cannot guarantee that the music is protected from "theft" then the RIAA will pull the plug on our "cheap" downloading.

    Because Apple needs to stay friendly with the music industry, and that means the RIAA. They'd probably wouldn't mind skipping encryption altogether and saving a buck, but I doubt very many labels would support that scheme.

    Your country has a rather annoying tendency of assuming they have legal jurisdiction over the entire world. See Dmitri Sklyarov, for example. Jon Johansen should be safe provided he never sets foot on U.S. soil any point in his life (the major mistake that Sklyarov made). They probably don't care enough to extradite him (and would likely fail in any case), like they are attempting with Bobby Fischer (admittedly, a U.S. citizen at the time).

    Try reading my comment again, more slowly. The analog hole is not closable. It quite simply cannot be done. For instance you could take an encrypted digital speaker set, and attenuate the signal going to the speakers down to a 0-1.5V P-P signal, aka "Line Level".

    The digital hole is where you make a digital copy without degradation. The former motivation (besides ethics) for consumers to purchase commercial copies of media was quality. Now, with the ability to make a perfect digital copy, that motivation has gone away. Now it basically comes down to convenience and ethics. It's hard to feel too bad about taking some money away from a record label, and it's awfully convenient to just download music without paying for it. Hence the reason the record labels are pissing their corduroys.

    On the other end of the spectrum, maybe he's a hardcore PC guy that wants to use the brilliant systems (hardware and software) that Apple has created. iPods are lauded as the greatest thing since sliced bread, QuickTime, while a little bulky of late, has been an industry standard for years(vs. the bastard child WMV), and Mac software generally just works, and looks good doing it. Read the Apple Interface Guidelines sometime, just the bullet points on the main screen sum up their philosophy.

  13. songs stripped of DRM transmitted through the air? by SuperBanana · · Score: 3, Insightful
    Anyway, back on topic, I never really understood why Apple felt the need to encrypt it in the first place.

    It is encrypted because otherwise you're transmitting copyrighted works over a medium easily sniffed. The AAC file you bought from iTunes, which can't be played on anything but the system you authorized it for (simplifying here, calm down nitpickers) would be transmitted unencrypted to the Airport Express. It would be an excellent way to decrypt your files and do whatever you want with them- all you would need would be a second machine with a wireless card, or probably even just running a sniffer locally on the system doing the transmitting.

The Fairplay DRM is one of the fairest rights management systems out there as you can do anything you want with the music you buy except directly convert to a different format. Burning to CD is unlimited. What if his actions cause the music industry to loss confidence in that DRM?

    What is the alternative? WMA? do you have unlimited burns? No? Do you have uniform rights across all songs? No. Can you play WMA in all players including the iPod? No. Ok this last point is equally bad for iTMS and WMA stores but I don't like WMA. iTMS does have one advantage however, it is compatible with both the mac and windows.

    If Jon really was a genius and was trying to do the public a service, he would have cracked the WMA DRM. If he could come up with a way for me to be able to purchase songs on Napster (no iTMS in Canada yet) and being able to convert them to AAC format with EasyWMA to play on my mac and iPod, that would be useful to me.

    Destroying iTMS is not useful to anyone. Apple's DRM is the lesser of the two evils and it's free enough for me since I don't run linux. Jon is an man with raw intellect but no common sense.

    Since when is using a publicly available public key to encrypt a stream of data from an application and send it to a device considered "cracking?"

    I wasn't surprised that the first source I saw report this called it a "crack," but had hoped by the time the story made it to /. the error would be corrected.

    By the way, you do a real disservice to people trying to fight the DMCA by calling things like this "cracks." Lawyers for the bad guys already think these sorts of hacks are actually illegal cracks. You're bolstering their opinion by conflating the two.

    What if his actions cause the music industry to loss confidence in that DRM?

    LOL!

    Understand this... The "music industry" is royally screwed seven ways from Sunday. They know it too, don't kid yourself otherwise.

    See, they need *customers*.

    In order to exist, the music industry has to convince people to buy what they are pushing. They're between a rock and a hard place here, because if they make that DRM too obnoxious, if they go beyond the line too much, then their own customers will flip them the bird and jump right back onto P2P networks. It's already happened once, in their eyes. Does the P2P scare back around 1998 ring a bell? Napster? Back when it didn't quite suck, I mean.

    See, Napster opened a new world for the music industry, because it showed them that the world had changed and now they had to compete with "free". How in the hell does one compete with free products?

    DRM is a reaction to this, by trying to make it difficult for people to convert their products into a format than can easily become "free". Unfortunately, this is an impossible task. It's *proven* to be impossible, no less. So they now have to not only compete with "free", but to do it, they have to do something that's absolutely and totally impossible to do. What a bind that puts them in, huh? :-)

    The music industry is scared shitless, and with reason. This new medium takes their products and puts it into a form that:
    a) damn near eliminates distribution costs,
    b) makes low cost viral marketing into one of the most powerful forms of marketing there is through the rapid dissemination of the meme in question,
    and c) eliminates all ability to control distribution of their product and thus be able to charge for it.

    A and B they love, but C is included in the bargin and they cannot escape it. Furthermore, they're starting to figure out that the combination of A and B on a large enough scale eliminates the need for the middlemen in their business. Artist and customer can directly interact just as easily as middlemen and customers can. Since most of them are middlemen, this naturally makes them nervous. Right now, they're engaging in heavy media spending to combat this knowledge, leading to the current meme of "taking music without paying is stealing" and so on. They're engaging it on both the artist side and the customer side, and if both sides would just wake the hell up, the middlemen would be out of jobs.

    So what I'm saying is that the idea that they can NOT offer their product on the internet is an unrealistic notion. They don't have that choice, not really.

    If they don't offer something out there, in a light enough restriction no less, then what will happen is that they eventually die off. People will go back to passing around music for free, legislation and lawsuits be damned, they will find a way to do it safely if it comes down to it. Many very bright people are already looking for that way.

    And if the artists see that the music companies aren't actively trying to make them some cash by selling their music online, the artists might start waking up en masse and seeing that the old system is unnecessary with the new technological capabilities to directly reach the customers.

    So the music industry *will* sell online. They don't have a real choice not to do so anymore. They can no longer pack up their toys and go home, because that would be a losing move.
