Apple Can Remotely Disable iPhone Apps

Posted by Soulskill on Mon Aug 11, 2008 04:02 AM
from the they're-making-a-list dept.
mikesd81 writes "Engadget reports Apple has readied a blacklisting system which allows the company to remotely disable applications on your device. It seems the new 2.x firmware contains a URL which points to a page containing a list of 'unauthorized' apps — a move which suggests that the device makes occasional contact with Apple's servers to see if anything is amiss on your phone. Jonathan Zdziarski, the man who discovered this, explains, 'This suggests that the iPhone calls home once in a while to find out what applications it should turn off. At the moment, no apps have been blacklisted, but by all appearances, this has been added to disable applications that the user has already downloaded and paid for, if Apple so chooses to shut them down. I discovered this doing a forensic examination of an iPhone 3G. It appears to be tucked away in a configuration file deep inside CoreLocation.'" Update: 08/11 13:07 GMT by T : Reader gadgetopia writes with a small story at IT Wire, citing an interview in the Wall Street Journal, in which this remote kill-switch is "confirmed by Steve Jobs himself."

[+] Technology: Why the Kill Switch Makes Sense For Android 384 comments
Technologizer writes "It came out this week that Google's Android phone OS, like the iPhone, has a kill switch that lets Android Market applications be disabled remotely. But it's a mistake to lump Google's implementation and Apple's together — the Google version is a smart, pro-consumer move that avoids all the things that make Apple's version a bad idea."

                    All fine and good, but I'd counter-argue that if YOU can't comprehend why it's potentially very BENEFICIAL for a carrier to be able to globally "kill off" some new app that turns out to be a trojan horse, leaking out your private information everywhere ... then I don't know what to tell you, really?

                    It's one thing to claim you're "perfectly capable of deciding for yourself what you want on your phone" ... but another for that statement to be truly 100% accurate.

                    Working in I.T. as long as I have, I, too, like to feel "in control" of the devices I use. Most of the time, I know what I'm *trying* to install and leave out on the computers I use. But the problem comes in because none of us have time (or even the ability) to audit the source code for each program we install. We have to go on faith that apps do what they say, most of the time. We can pay other people to act as "watchdogs" for us, which is essentially what paid subscriptions for anti-virus/anti-spyware software really are. But ultimately, we still have to trust SOMEONE, or else we'd never install ANY new software on a computer, a phone, or other electronic device, out of fear it might destroy our data or send it where it's not supposed to go!

              Security is layered.

              Applications have permission to run by virtue of the fact that they are signed by Apple. That certificate can be revoked. (The so called kill switch).

              This black list deals with apps that make inappropriate use of Core Location, but are otherwise OK. For example an app might constantly use explicit Core Location requests to find the current location. That would drain the battery in no time. (versus requesting to be notified when location has changed by more than a threshhold). The App is non-malicious, just sloppily programmed. Apple could blacklist it's core location functionality, whilst leaving the rest of the functionality working. Until such time as the developer produces a fixed version.

      Shouldn't be used unless it's deemed "dangerous".

      Who decides what's dangerous? Are pirated apps going to be deemed dangerous? If you bypass certain security measures, is that dangerous? I don't like control being taken away from me (where "me" in this case is any end-user).

      Even if the intent is to only blacklist malware, does apple have a research lab to determine whats malicious and what isnt? Will they tell us how they decide on malware? What if you release an app that is infected with malware, the app is still legit whereas the malware part of the code is not. What happen if that app gets blacklisted, can it be revoked? If the iPhone contacts a webpage every now and then, will apple pay the bill for the connection?

      I don't like this, at the moment I don't like it because they did it without saying they are doing it. Going forward, they should say what they intend to block and give the enduser and option of either using the "service" or not... especially since the end-user is the one paying the bill for the datatransfer, the amount of money is imho completely irrelevant.

      • by rsmith-mac (639075) on Monday August 11 2008, @06:05AM (#24553753)

        Based on what Apple has told developers since the start of the program, revocation appears to be certificate based; Apple is revoking the developer's certificate for that program, which breaks the authentication chain and prevents the application from running. As for what they can block, it does not look like this would be effective against a jailbroken kernel, since much of the authentication chain is patched out anyhow; in other words they wouldn't be able to revoke: the jailbreak, applications for it, and perhaps even regular applications once the jailbroken kernel is installed.

        As for what they'll revoke, that's the bigger question. Apple has not shown to be particularly hostile towards the jailbreak community in the past; even if they could revoke it, I don't believe they will. The real test on this policy would be the NetShare application, it's an application Apple has ceased to allow post-release and if the revocation system were to be abused it would be the prime target. So far Apple has not revoked it, even though they've had ample time to do so.

        That leaves us with malware. I don't find this to be something hard to define, but perhaps other Slashdot readers do. If the application is legit but has a problem (backdoor for exploiting the Mobile account, for example) I'd assume Apple will revoke the certificate for the bad application and let the author issue an updated version as long as they didn't intentionally create a problem (which is grounds for being expelled from the AppStore program). If it's outright malware that somehow passed Apple's QC, then they'll still revoke it, will not issue further certificates to the guilty party, and since they had to sign up for the program, track the guilty party down and sue them for computer crimes in some form.

        I'm not too worried about this (I consider blocking malware from running a good thing) but I can see why other people here would be worried. In either case it's a well thought-out system that seems to cover every contingency, so there shouldn't be any "friendly fire" of applications being unintentionally revoked.

            "Oh, but's Apple, and this is good! Want to know why the PC prospered? Apple around the time of when it could have gone its way introduced an SDK development process where every developer who wanted to deliver something had to have a developer token. Without the blessing of Apple no go on Apple hardware! It annoyed many developers and the rest is history...

            Don't believe? Do some historical checks..."

            Really, I was an Apple developer back in the day, moving from the Apple II all the way to the original Mac (the all in one) and then getting out of the business a few years later.

            I don't remember EVER contacting Apple for the SDK. I simply bought Lightspeed /Think C and Pascal and developed. Want more in-depth info? Get the Inside Macintosh books. I had like 2 dozen...each taking up a few hundred pages, and each focusing on an API and/or group of related items. Things like Audio had entire volumes written about it (this was my focus).

            In this time, I *NEVER* once asked Apple for a 'token'...it wasn't needed. The most you'd ever need would be to have an official App ID (or whatever it was called) that ensured that documents created with specific doc types would know what application would open it -- and to keep other developers from trying to usurp yours. It could easily be done on the local computer.

            Honestly, you don't know what the fuck you are talking about. This falls into the realm of not just ignorance, but making shit up.

        Of course it's within the realms of possibility that Amazon may misuse it, but the benefit I get in a wide access to cheap books outweighs my risk.

        On the other hand I'd expect Scammy Viagra Co to misuse it.

        It's perfectly reasonable to accord different companies with different levels of trust. And giving out your credit card number is a far more significant trust level than allowing a company to prevent selected apps from accessing your current location.

        I do trust Apple to use it responsibly. I wouldn't trust Microsoft to. And there's absolutely nothing wrong with that. All companies are not the same. Microsoft's evil misdeeds negatively affect their trustworthiness, but they don't affect all other companies too.

        This is actually a few days old; it did the rounds on the Apple rumour sites and was debunked: it's a blacklist that can prevent applications using Core Location to determine a users' position (so if an app is abusing it & logging everywhere a user goes, they can be prevented from doing that while still allowing the app to function).

        The hint was in the filename (and the library that references it): clbl - Core Location BlackList

      Actually, when you stop to think about it, every cell phone in existence does just that, as all of 'em continually poll local cell towers to tell the servers that they're in that particular neighborhood. You might not have known it's doing that, but it does.

      Except that it doesn't. The blacklist in question does not blacklist applications on the phone. It's a registry of applications which the user denies access to the "Core Location" service - i.e, when you don't want the phone to use GPS or triangulation data for privacy reasons.

          It's not like Apple is collecting user information here. It's a HTTP GET as far as I can tell, with no information being supplied to Apple, just a list of applications that are bad and that the user shouldn't run for their own protection.
