Your Smartphone Is Safer Than Your PC — For Now

snydeq writes "InfoWorld's Galen Gruman reports on the future of mobile security — one that will see a significant rise in exploits as valuable information increasingly migrates to mobile devices. To date, sandboxing and code-signing have helped make mobile OSes relatively secure, when compared with their desktop brethren. But as devices store more valuable information than email, they will become more enticing to hackers currently breaking into Windows PCs. And the biggest bulls-eye appears to be on Android, in large part because its architecture is most like that of the desktop PC but also because there are so many variants in use — too many for Google or the carriers to patch securely. And as the PDF-jailbreak vulnerability showed, sandboxing has its limits when it comes to securing the browser — the most likely point of entry for exploits not due to the rise of extensions, helper objects, and plug-ins on the mobile Web."

      It's already happened on Android. Manufacturers are out making their latest rev and they ignore the bugfiles to their current line of phones. Or they do and pass it onto the carriers who may or may not force an update. Of course, if said update will remove things like root and custom ROMs, they'll probably push it.

      But phones getting abandoned at whatever Android version they shipped with are already happening - I think the early Samsung phones were promised 2.0, but ended up with 1.6 only with an official letter. And others are stuck with 2.1 with no upgrade to 2.2. The only good part is these phones often are early models and easy to root and recover, so unofficial ROMs exist. But later ones may not be so lucky.

      Really, the only Android phone that's not under carrier control is the Nexus One, which gets updates straight from Google. The wierd thing is, why can't Google pull an Apple? The iPhone gets updates from Apple, leaving out the carrier middleman, even if the user is paying a contract on the iPhone.

      Because Android is an open platform. The carriers take Android, mold it to fit their needs, and put it on their phones. Google, or rather the Open Handset Alliance, doesn't have any say on it. That's how carriers can get away with modifying the source of the Hotspot app to only work if the customer pays extra.

      This is the downside to GPLv2. The Tivoization loophole means that carriers can do this, release the source, and you still can't (necessarily) modify the source and put it on your phone.

      Google started taking steps to address some of this by moving more of their apps to the app store, but you still have issues with system libraries and the kernel. Without root, an app can't update these.

      "The wierd thing is, why can't Google pull an Apple? The iPhone gets updates from Apple, leaving out the carrier middleman, even if the user is paying a contract on the iPhone."

      Partly because it isn't that easy - these things are often using custom drivers or require custom kernels to run. Yea, some of it is junk but much of it isn't. How are they going to update a bug in Motorola's GPS driver? Or even *why* would they? Lets face it if you had a custom bit of hardware that you had a linux driver on would like Ubuntu to push a new kernel to your device because it can? Nope, especially if that device was a core operational feature. It would be a nightmare to push an upgrade and break phones - it isn't like these upgrades are within the Dalvik VM - those apps can fairly safely be updated across everything, low level upgrades not so much.

      If Android and the phone versions of Linux mature enough to have a true Open Source following we may get something like Linux is today. That is a lot of hard work by volunteers to make drivers for every major phone out there. Now some phones will still have restrictive boot loaders and such, but not all (and I will bet most) will not. It *can* happen but will require Android and it's linux underpinnings to stop it's rapid development and give volunteers time to get things in place - that isn't going to happen for some time. There is a devoted following right now making root exploits and custom roms - many times those custom roms are truly not wanted by the manufacturer but such is life in the open source world. When that happens we can run supported builds while under maintenance (or our carrier contract) and re-build with a Canonical build afterward :)

      There *will* come some point where the technology matures enough that there just isn't that many updates. Compare development in the early 2.x tree of the Linux Kernel to how stable the current 2.6 tree is - heck compare just the 2.4 to the 2.6! At some point we will also not really feel the need to upgrade hardware either - PC manufacturers are hitting that and simply reducing quality so you have to re-buy nearly the same thing every few years. Further I think our phones are marching towards becoming our general purpose machines. As that happens the market will force some level of stability and customability on it too as people *can* realistically reverse engineer things and write an community driver for it.

      Further it isn't even like Apple is immune to the issue - ask people with anything before a 3g how they like their current crop of updates with iOS 4 - chances are you are going to get some grumbling there. Then ask the iPhone 3 users who saw a significant slowdown after the update and you can see that even when you only have *one* hardware specification how hard it is to do. Even with the lockdown Apple has they can't do it to the point people want to make them out to have achieved - they only achieve that *if* you have compatible hardware which is true with Androids too. It's even arguable which is the larger group affected - only *some* older android users are whilst *all* older iPhone users are.

      Ultimately the more freedom one has the more responsibility one has. This includes things like making sure you purchase upgradeable hardware and know how to do it. The more locked down a system is the less you have to worry with it but also the less you can deal with it when it occurs. Apple chose the latter route, Google chose the former. I think Google will win for a number of reasons - the above being one (Apple could win handily if they simply opened up the app store and ability to install unsigned software - but I do not think they will as long as Jobs is at the helm).

      And it hasn't been because of some great security model either - there has been now for weeks an iOS exploit that if you open a correctly formed (or rather malformed) PDF it silently roots your phone and installs any software it wants on your phone. It has access to *everything*. You can not tell me that is "good security". The Mac isn't any better either.

      It hasn't been an issue for one of several reasons.

      One is that no one had taken advantage of it beyond jail breaking phones. One needs to think through the implications of *that level* of an exploit out in the wild for this long and it not being taken advantage of. There is no *technical* reason why it couldn't this day be used to send your e-mail, browser history, all forms your fill out, pretty much everything you do to someone and unless you monitored your traffic and only used your own wifi would you know for certain. For the most part I think the macs have been in this category - if you are going to spend that effort it is better spent elsewhere.

      Next is that exploits do not make news unless they are large enough. Windows exploits are often scripts that almost anyone can run and almost anyone does. iOS ones are more likely going to be one off custom scripts that may gather 10000 credit card numbers - unless someone has an anti-apple leaning (or anti-android if it happens on that platform - nothing remotely Apple centric here) it just isn't news. If I were to guess - and I think I'm more correct than not - there are a number of malformed PDF's out there that do just that. There just aren't any that propagate themselves through e-mail to everyone in your users list and thus make the news.

      Lastly - and most unlikely - is that there is some conspiracy to silence it. Too many places out there that can say it for this to be true.

      Ultimately there is going to be a major worm or virus out there for one of the main hand helds - RIM, Google, or Apple. They are becoming too much a general purpose machine. Whichever one gets it first will loose a great deal of market share for a while while the other two crow about how wonderful they are. They aren't and never have been. Android is more open to attacks on older phones, Apple more open to attacks on all their phones, and RIM is somewhere in between. Apple and RIM can probably handle it quicker but you are more bound to them deciding it is worth fixing and doing so. Lastly what the OP said is true - Apple and RIM users often seem to think they are immune to this. Both phones have some fairly major exploits that have happened and went further than they should because of this.

      Such is life in our industry - number of known bugs, number of known exploits, and number of exploited users are irrelevant when talking about how secure a system is. There is a saying: security through obscurity isn't security. This has certain logical implications - one of those is that not being secure means you have a lot of *known* bugs (thus not obscure). It also implies (but doesn't logically prove) that just because you haven't had one means you are secure - it means there are MANY other factors there.

      Were I to bet I would say Android will get the first followed closely by Apple simply because they are the two big players in the consumer market (corporate being fairly locked down) and the fact that there are more older Android out there means more known issues. Though given how Apple has responded to the PDF remote exploit I wouldn't give much more than even odds on it either. There have been more than a few truly serious exploits on Apple systems go out that were either never exploited (and you can supply your own reason for this given the length of time a number of these exploits remained live) or were not generally reported on. You response when one takes the whole PDF remote exploit into account more or less validates with the OP was saying - that I left my alarm off, all the doors and windows open on my house, and I put a big sign in yard that told people of this fact yet I wasn't robbed doesn't mean I was secure. That you think you are is *exactly* what he/she was posting about.

There's no evidence to back that statement up, and there's no evidence that Android less secure just because there are various flavors. In fact that can make it harder because one hack might not work on multiple flavors. That's even one of Androids problems now, that it's sometimes difficult to get a single app to work on multiple Android OS devices. You could then posit that the iPhone is easier to hack because the OS is so similar and the number of iOS devices in the wild is much higher than Android. But that's BS too because the iPhone is such a locked down system that in order to install anything you have to go thru the iTunes app store gatekeepers. The other way in is thru Safari, but that's really the only other way, and well now we know the security of Safari is BS because of that hole that they found in iOS 4 they used for jailbreaking. But compared to windows and compared to each other, which of these has had more critical vulnerabilities? The article gives me nothing.

    Despite all this positing, it comes down to number of hacks, and what the hacks are. I could not truly begin to tell you which handhelds are more secure than others because no one, including this article, has any facts.
