Apple AirPlay Private Key Exposed, Opening Door to AirPort Express Emulators

Compile and Run

Is anyone here educated enough to explain to me how to compile and run this thing?

I can't find a way to install avahi. Tried installing it via fink - no luck.
MacPorts requires xcode, but I don't really want to install xcode. takes up a lot of space.
Even though I know some things I'd still prefer if someone would make a step-by-step how-to for me.

Thank you in advance.
 
Lucky its not Sony. Those that exposed it would be in a never ending court case, and everyone's IP that visited macrumors would be subpoenaed by a federal judge.

Should be public anyway, why can't we have cool 3rd party devices?

Because the 3rd party device could be in your neighbours house so your neighbour can see or hear anything that is played through AirPlay from your devices without you knowing. And you might be playing stuff that you wouldn't want your neighbour to see.
 
You can bet they are working on a new Firmware/Update to close this loophole Ole Stevie boy will not be a happy bunny today
 
Darn criminals.
I hope their iDevices get banned from iTunes and these terrorists will be brought before court. :D:apple:

Care to actually show me what app that will actually do what I was talking about? :rolleyes:
I want to play music from iTunes on my Mac as the source, and multiple airplay devices as the target. Currently I can only play to Airport Expresses and Apple TVs (and upcoming Airplay certified speakers). I want Apple to include all iOS devices to that list of target devices.

As mentioned multiple times in this thread: Airfoil
Airfoil runs on your Mac, Airfoil Speakers on your iOS devices. Start Airfoil Speakers (which is a free app) on your iOS devices and then select inside Airfoil on the Mac on which devices you want your sound being played. You can let it play on multiple devices at the same time and the app does a decent job of synchronising the sound. In addition to iOS devices any Airport Expresses and Apple TVs can also be selected. And you can select to broadcast the sound of individual applications on the Mac only (eg, iTunes only to avoid other system sounds being transmitted).

Or, for simpler needs, just enable Home Sharing in iTunes and play your Mac's iTunes content directly from your iOS device.

They already do. Use homesharing and you're all set. Or use Air Foil and get it to work exactly as you describe. Not big on research, eh? ;-)

Wouldn't that require your neighbour to be on your WiFi network?
 
Should do some research

Ok this makes no real sense to I figure Apple is behind it. Merantz and Denon both have upgrade and both same price. Are they for real, come on Airplay upgrade WTF. I smell Apple crazy behind it. :rolleyes:

I guess its a software upgrade to their internal chip, but I still think its stupid, if your going to buy a 1000 plus receiver this is just dam bad PR to me.

Denon and Marantz are the same company, two pieces of D&M Holdings.

The discussion about this here is ridiculous. There are many good reasons that Apple has to encrypt the music data stream. First, it's a privacy issue--If encryption were not standard people would be even more widely angry that Apple provides an insecure product that allows others to snoop on one's audio stream. Furthermore, in order to license all that iTunes Store content Apple has no choice but to provide security in its delivery mechanisms. Movie and music studios are big into the whole idea of encrypted data streams and would stand for nothing less.

Now that the key is cracked, the security is theoretically defeated (someone just has to write a program to hijack data streams) and the studios no longer have their hacker-proof data stream. Apple probably doesn't care though because they did their due diligence and forcing a firmware upgrade with a new key (which would just be cracked again anyway) would be impossible and fraught with problems.

That's not quite correct. Yes, the RAOP stream can now be decrypted, but the stream itself goes over your Wi-Fi network. So long as your Wi-Fi network is secure then no one outside the network can touch the stream. And if you haven't got WPA2 set up, you've got far bigger problems than your neighbours watching your homemade p0rn.

Some people have already mentioned AirFoil for audio, and there's AirView for video.
 
This is pretty awesome unfortunately my FreeBSD Server sits right next to an Airport Express :rolleyes:

Only if i set my neighbors device as a speaker in iTunes...which would happen not too often without me knowing.

Check out the Airframe and Airview apps in the App Store. They do what you want but unlike the Apple TV and Airport Express, you have to have the app open for the device to be recognized as an Airplay target device. Airview is free and Airframe costs a couple of bucks but it supports tv out which Airview does not. Neither support DRM content though.

But instead of using those apps, Apple already provides a solution in iOS 4.3 with iOS Home Sharing. It makes more sense in my opinion that way anyway. If you want to listen to music on computer with your mobile device it's usually because you have it in your hands which means a "pull" type solution like Home Sharing would be beneficial. A "push" type solution doesn't really make much sense unless you have your mobile device connected to a TV or some speakers. But then that's what the Apple TV and Airport Express are for.

This is great news, I've been waiting for something like that for ages.

For all those people that fail to see how it could be useful, consider the following scenarios:

I got my Mac connected to some great speakers.
Now, a friend comes by for a visit, brings along his laptop and we want to hear some music from his iTunes --> messy cables, my friend standing with his laptop by the amplifier because that cable is short (…)
Another friend comes over. We want to listen to music from his/her iPod/iPhone/iPad --> messy cables.
My beloved speakers are self-amplified and connected directly to my mac or say, an external sound card --> even more complicated!
Same friends, different room - let's say a living room with a HTPC --> More cables.

All this could be accomplished with a few airport express units across the house which is somehow a luxury option money-wise and somehow redundant since I already have a wireless router and at least one computer up and running. Also, it would probably create more of a mess with the aforementioned setup (I would need a multiple input amplifier for my living room or an extra mixer for self-amplified speakers). Don't get me wrong, I think AX is a great device and I'll probably get one someday, but it sounds absurd that one device cannot stream audio to a computer.

And for those suggesting third-party software, this sounds great if I were the only using them. I cannot imagine telling my friends "hey, buy this $40 software so we can stream music to each other's computer". I'm not sure I could even convince them to install free software to mess with their audio setup. iOS users are ruled out of course.

For those suggesting iTunes home sharing: this is for personal use. I don't want to share my id/pass with anyone, and no one wants to share it with me.

THIS

As you correctly highlight, the significance of this isn't that it enables others to implement 3rd party Airplay clients for innocent playback... it's that it allows Airplay-based software rippers to be constructed.

Want an un-encrypted copy of that iTMS rental movie? Stream it to an airplay-ripper you've downloaded off the 'net, and it'll be re-compressed in non-DRM form for you to play back whenever you wish.

This is the biggest worry for Apple. They can't raise lawsuits against free software apps hosted outside the US in the same way they could block the selling of non-licenced hardware in the US.

This isn't exactly right, this hack is only for AirTunes (i.e. music). AirPlay for videos works in a different way and uses the same FairPlay DRM as the rest of Apple's stuff. In theory AirTunes being hacked is less of an issue because iTunes music has been DRM free for a few years now. I doubt music execs think like that though! Apple probably don't either, especially if they have a music subscription service on the horizon.

Unfortunately fixing the DRM might be pretty easy. It depends on whether the Airport Express uses the same private key as third-party AirTunes receivers or not. If it uses a different key then it's just a matter of pushing updates for Apple's own stuff.

Airfoil still needs the Airfoil installed on your computer to work, it won't run with just the iOS apps. I think pika2000 is asking about iOS apps that emulate an airport express, so that you could send the same audio to every device in your house.

Well, you CAN send the same audio to every device in your house, as long as the audio originates on your Mac (which includes simply plugging in any iOS device or iPod into your Mac).

Probably workin' 24/7 on it as we speak... I hope Apple finally stops being Sue Zombie, and realizes the advantages to the consumer for this.

Apple, go back to the logic that made you what you are - make products for the consumer's hearts & thoughts!

ZumoCast does this quite well and it was free! Im able to stream my itunes music, as well as videos on my mac to my iPhone and iPad. It's no longer on the AppStore while they make improvements, but the website is still up.

You can use Airfoil and Airfoil Speakers to stream music from a PC/Mac to a PC/Mac/iOS/Airport Express device
