Researchers Find iOS Malware That Infects Non-Jailbroken Devices (paloaltonetworks.com)

An anonymous reader writes: Researchers at Palo Alto Networks are reporting about a new iOS malware that could infect non-jailbroken devices without a user's consent. Dubbed "AceDeceiver," the iOS malware exploits a flaw in Apple's DRM software. The researchers claim that the iOS malware could technically infect any type of iOS device, provided a user downloads a third-party app. From the blog post on Palo Alto Networks' website, "AceDeceiver is the first iOS malware we've seen that abuses certain design flaws in Apple's DRM protection mechanism -- namely FairPlay -- to install malicious apps on iOS devices regardless of whether they are jailbroken. This technique is called "FairPlay Man-In-The-Middle (MITM)" and has been used since 2013 to spread pirated iOS apps, but this is the first time we've seen it used to spread malware." The aforementioned malware required users to download a compromised Windows application. Apple has removed three offending apps from the App Store, and it appears that only users in China were targetted.

      Will Apple stop their fear mongering now? Their entire argument is moot because iphones are not secure while they are being used. Physical access to a device with a person skilled in changing firmware on an ios device would be needed to 'hack' an iphone under the scenario they are supposing will happen if they give the FBI a back-door, which would cover a very very small percentage of 'hacks' out in the wild - your iphone is at far more risk just by turning it on and using it.

    Well that's what happens when you have software that ignores the user's actions and overrides them. You want to do it "for protecting copyrights", but the software isn't coded to obey copyrights (it wouldn't be DRM if it did, since the copyright owners don't want their copyrights managed to the extent of the law, they want extrajudicial rights you cannot get returned by a court case), so it doesn't give a shit what you want to use it for, it just avoids letting the user use their device for what they want and insists on overriding it.

  7. The tl;dr version of how the attack works by Anubis+IV · · Score: 4, Informative

    For those interested in how the attack works, it relies on having a specific piece of malware (something akin to a rogue version of iTunes that runs in the background) installed first on your PC. After that, from what I understand, the attack roughly goes like this:

    1) Attacker submits a piece of iOS malware to the official App Store and has it accepted.
    2) Attacker purchases their own iOS malware from the App Store, receiving an authorization code for the purchase.
    3) The PC malware gets the authorization code from the attacker.
    4) The PC malware masquerades as iTunes to tell your iOS device that a new purchase is ready to install.
    5) The PC malware provides the authorization code it received from the attacker.
    6) Your iOS device downloads the iOS malware from the App Store.

    Strangely, even though the offending apps have been pulled from the App Store, they're still available to people who have previously purchased them...including people who are getting infected via this attack, since that authorization code acts as proof of a previous purchase. Your device just thinks it's a previous purchase you made in iTunes but hadn't yet synchronized over to your device.

    As for how the iOS malware was able to get into the App Store in the first place, apparently they were using geolocation to make the app display benign content in the App Store reviewer's location (in this case, they were acting like useless wallpaper apps) while serving up malicious content in China.

      The long string of events here makes it sound like this is relatively benign but it's actually pretty serious. There's no way that an App Store can be policed perfectly. It's impossible to secure Windows. Which means that this will become a depressing game of whack-a-mole. But it also seems here to imply that a purchase authorization code can be shared! Which only makes this worse as people may install the malware for the promise of free, paid apps. Probably the weakness of reusing authorization codes is well know, but it was new information to me.

    I don't mind you going there. Android phones have a theoretical patch window of 1.5 years. And that clock starts ticking immediately after the device is released. So, if you're like me, and you wait for a phone to become inexpensive, you have - at best - a practical patch window of about six to eight months. That's it. It's even slower if you buy a phone from a carrier. Guess it takes a lot of time to bloat up that ROM with those carrier based tracking apps, CarrierIQ, anyone? What really gets my goat is that AT&T usually patches their their phone updates after Verizon (if at all).

    I have a 4 year old AT&T Samsung S3 or i747, a four year old phone) which has Lollipop 5.1.1 (CyanogenMod). I also have an AT&T Samsung Note 3, a three year old phone, also from AT&T, but it is stuck on Lollipop 5.0.1 (TouchWiz). The S3 is going to get Marshmallow, while the Note3 development has all but stopped.

    The difference is just one small thing: The S3 has an unlocked bootloader, and the Note3 has a locked & signed bootloader. The Note3 cannot possibly run anything other than an AT&T blessed TouchWiz ROM. Shame, really, as the Note3 has some nice hardware (and screen real estate) compared to the S3.

    TL;DR Don't buy an Android phone from a carrier, and be sure the one you get doesn't have a locked & signed bootloader, so you can do the updates that the phone vendor won't do.
