iTunes 4.5 Authentication Cracked

fooishbar writes "Yesterday, Apple released iTunes 4.5, which deliberately broke the 4.2 authentication scheme, which had been successfully reverse-engineered. However, crazney has been at it again, and within 24 hours of downloading iTunes 4.5, has broken the new scheme, and added more features to this library along the way. If you want to incorporate iTMS support in your program, give libopendaap a go!" Reader ScottGant submits this story about the Pepsi/iTunes promotion: "News.com has this story about Pepsi's iTunes promotion give-away. The promotion, which is slated to end this Friday, was to have given away 100 million tracks through Apple's iTunes music site. But according to Apple on Wednesday, only about 5 million free songs have been redeemed."

    I live in NYC and have seen exactly 1 bodega with iTMS Pepsi bottles.

    Maybe someone forgot to ship these things to places where people actually would use them?

    That's because for a "free" song you had to give them your credit card number.

    No, you didn't. I got two free, no credit card required.

    I dunno what iTunes *YOU* were using, but I never had to give my credit card # and I'm on free song #9 and counting...

    You did not purchase the song. Read the agreement. You purchase the right to listen to the song subject to the conditions outlined in the agreement. If the agreement is not to your liking, do not purchase the song.

  5. Right-- fairplay still works. by Anonymous Coward · · Score: 4, Informative

    This is about authentication with the itunes music store, not removing the playfair drm protection.

    Fairplay still works without any changes. A "friend" did the following last night:

    1. Using an old version of itunes on a pc, purchased a new song from the music store.

    2. Launched VLC on the PC, and found it had no problem playing it. Checked c:\documents and settings\[username]\application data\drms and there was a new file: XXXXXXXX.005, in addition to the other two files that were already there. They had extensions .002 and .004

    3. Upgraded itunes on the PC to 4.5. Bought another song. It shows fairplay v2 when you look at it's info.

    4. VLC can also play this one. No new file in the drms directory was created.

    5. Copied both songs.m4p and the key files from drms to the mac running the latest itunes. Put the keys in ~/.drms

    6. Ran playfair (v 0.5.0) against the two songs. They decoded into .m4a files which show no protection, and play fine in VLC, and itunes.

    7. Just to double check, bought a third song using itunes on the mac. Ran playfair against it (still using the keys from the PC) and it decoded and plays fine.

    My conclusion is that as long as you have the keys, you can still use playfair. My friend gets the keys from the PC running VLC. I don't know if other techniques may have been broken by the new itunes.

    I don't have any problem with the ethics of removing the protection. I don't-- I mean, *wouldn't* use it to illegally share the music. It's just nice to have clean files in case Apple quits developing itunes for the PC, or some other unlikely scenario.

    Except you didn't have to give them a credit card to get the songs. I didn't have to put in any credit card informtaion until i actually bought a track -- after i had downloaded 18 free iTunes songs. So yes, they were actually free. You only needed to give them an email addy to create the account (or at least I did, but i used the account i'd had with apple for 2 years, so they already had my email).

  7. Upgrade the other machines! by RatBastard · · Score: 4, Informative

    What the planet of Hell do you need a workaround for? Just upgrade the other machines! iTunes is *DUM, DUM, DUMDUM* FREE (as in beer)! Is it really so hard to upgrade a free program?

    You do not need to provide a credit card.

    They ask for it if you want set up the ability to purchase music at the time you open the account but you do NOT have to provide it to redeem a free song.

    No, but most people on Slashdot don't know what they're talking about (including you it seems).

    Crazney has broken the pointless encryption on streaming things in the iTunes library to other machines on a LAN.

    It has nothing to do with iTMS. Repeat after me: it has nothing to do with iTMS.

    The encryption on streaming tunes between clients only serves two purposes: to try and keep people on the Apple upgrade treadmill and to force people to use iTunes on all their machines if they want to stream music between them from the iTunes library. This is your own music we're talking about here, no copyright violations are taking place.

    To be frank, Apple is taking the piss with this sort of encryption, and now the piss is being taken out of them. Too bad, but it has nothing to do with FairPlay.

    No it's not.

    Fat consumption has nothing whatsoever to do with diabetes. You could eat bacon 3 meals a day and not have high glucose levels. (Your blood pressure and cholesterol levels might not be so terrific...)

    Type 2 diabetes is one of two things: 1. You are not producing insulin fast enough to process large amounts of glucose in the blood.
    Or 2. Your body is not absorbing the insulin fast enough to do so.

    In either case, when you eat foods that are quickly turned to sugar in the blood (any foods which are high in starch or sugar, including white bread and potato products, and especially sugary foods like Pepsi) your blood's glucose level goes way up, because your body can't process it. This causes all kinds of problems. Fatty foods do neccesarilly raise your blood sugar levels. You may be confused because obesity (fat tissue, not fat consumption) slows insulin absorbtion, and is a contribuiting factor to Type 2 diabetes.
