Poking Holes In Samsung's Android Security 107

Orome1 writes "Tired of waiting for Samsung to fix a string of critical flaws in their smartphones running Android, Italian security researcher Roberto Paleari has decided to inform the public about the seriousness of the matter and maybe make the company pick up the pace. Mindful of the danger that the vulnerabilities present to the users if they are exploited by malicious individuals, he decided not to share any technical details, but to just give a broad overview of what their misuse would allow. This includes a silent installation of highly-privileged applications with no user interaction and an app performing almost any action on the victim's phone."

    The Exynos memory bug (often referred to as ExynosAbuse exploit) was released publicly and fixed rather quickly. This seems to be the way for Samsung - responsible disclosure just doesn't work with them. This has been proven time and again.

      After some further investigation, it seems all these exploits are fixed in the latest 4.2 leaked firmware for the SGS3, so ... they're actually fixed, just maybe not rolled out yet.

      Yup. And look at the eMMC "Superbrick" defect on many of the GS2 family. Many of those devices had a defect in the eMMC wear leveller such that the chip could be unrecoverably corrupted if you issued a secure erase command to the chip. (Probably about a 5% chance of it happening, it's similar if not identical to the defect that hit some of their desktop SSDs in late 2012). Not even JTAG could bring a "Superbricked" device back to life.

      After discovery of exynos-abuse, the only thing standing between Samsung and permanent damage to thousands of devices was the fact that modern blackhats care more about obtaining information (money) than doing damage. Samsung knew about this bug for many months - they were aware of the defect in the eMMC chips as early as Galaxy Nexus prototype development in 2011. Yet they released updates for devices in 2012 with kernels that allowed secure erase through to the eMMC chip. The only safe device was the I9100 - which had MMC_CAP_ERASE removed from the kernel to protect the chip. In June 2012, Samsung publically acknowledged the bug and claimed to be "working hard" on it - in July 2012 they released updates for the I9100 that turned the MMC_CAP_ERASE flag ON, putting those devices in danger.

      They had an official fix that blocked only secure erase merged into the mainline Linux kernel in September 2012, but not a single affected device had the fix deployed until 2013. Their "stuff takes time to get through carrier testing" line is bullshit. Sprint FI27 was *built* (as in, testing STARTED not ended) on September 27, 2012 (nearly a month after the official fix had been mainlined), and deployed to customers in early-mid October.

      As to the I9100 XWLPM MMC_CAP_ERASE fiasco, Samsung's answer was that the lack of MMC_CAP_ERASE in earlier source code was a mistake and that the source code did not match binaries running on devices (yes, that's right, Samsung's defense was "yeah bitches, we violated the GPL"). The strange thing is, this was one of the cases where Samsung's source actually DID match binaries - not a single I9100 ICS kernel prior to XWLPM and XXLQ5 had MMC_CAP_ERASE turned on. (This was obvious by the fact that no one experienced "Superbrick" on such devices.)

      Samsung's stance was that it was an "open source" problem, but the fact is, with a privilege escalation exploit, any malware could permanently destroy many of Samsung's devices to the point where a motherboard replacement (instead of mere JTAG) was required.

      In short, Samsung's "SAFE" marketing crap is bullshit. "Samsung Approved for Enterprise" - who did the approval? Samsung! Hardly an independent certification authority.

        You forgot to mention that you need root to issue this command. It's like suddenly panicking because root can overwrite the BIOS or use the ATA password feature to brick your HDD.

        • The exynos exploit allowed any application direct write access to all memory (essentially they can become root).

          It was pretty serious and they did take their time fixing it. Still I prefer my Android to an iPhone.
          There was third party fixes for the exynos exploit as well, but a user shouldn't be expected to know that.

          Exynos-abuse is a perfect example of such an exploit. ANY application could get root access with ZERO user interaction. The very article we are discussing is talking about privilege escalation exploits.

      This has been going on long before the smart phone,or even when it was common for people to have mobile phones.

      The only way to prove, and the only thing to do when a developer refuses to fix a bug, is to put the exploit in the wild. This is the only way to prove the exploit actually works in the real world. Until this happens the developer can just say it is a theoretical problem with no practical route to success, and as such does not warrant the resources necessary.

      That's an ISP problem more than an Android problem. During this transition from 2G to 3G to 4G-lite,* wireless carriers rely on subscribers not using all their monthly megabytes, and subscribers who use multiple devices on one plan tend to use more megabytes per month than subscribers who do not. Even a phone that obeys its owner (that is, one with a custom ROM) can't hide tethering-like behavior unless you run everything through a VPN. Carriers are reported to use traffic to Internet sites that host desktop OS updates, antivirus updates, and desktop application updates as evidence of tethering. By the time you've paid extra for a higher cap and paid extra for a VPN so that the ISP doesn't see what you're visiting, you might as well have paid for the tethering rider.

      * "Lite" because LTE isn't really 4G.

          For one thing, running a server at your house requires that your home ISP's terms of service allow running a server accessible from the public Internet. A lot of ISPs don't allow those on home SLAs. For another, when you bounce off a VPN at home, you're still transferring a larger volume of data per month when you tether than when you don't. How did you manage to work through those issues?

    Say what you will about Apple & the iPhone, but I appreciate the tight integration of OS & hardware and their desire to provide a consistent & reliable user experience. I own and use a (Sprint) Samsung Galaxy S2 Epic 4G Touch, and it was a series of broken promises on ever getting ICS. When finally rolled out, it wasn't the true android experience, but some half-baked Samsung-proprietary interface aka "Touchwiz." Great, that wasn't what I was sold when I purchased the device. I want android, not Samsung's half-baked, bug-filled, garbage-software-filled version of it.

    Eventually, I rooted and installed JB, because Samsung sure as heck wasn't going to do that. And then, as you venture deeper into the rooting environment, you find out a bunch of hardware/software issues directly caused by Samsung, including but not limited the EMMC super-brick bug. These security issues in TFA are just more of the same. For me, their handling of their android phones and my experience with them has tarnished their image across their entire product fleet. Will I buy a Samsung brand washer/dryer? There's a lot of digital tech in even washing/drying machines nowadays. Before this, their name wasn't an issue. Now, maybe I consider some other brand.

    • I swore off Samsung a few years ago when the 2.5 year old HDTV I had paid $1400 for died, and they wanted as much to repair it as a new TV would cost. Their products are shoddily made, and they don't stand behind them. They could produce the snazziest Jesus phone on the market and I wouldn't touch it with a ten foot poleaxe.

          I am. I have a ~7 year old Samsung 1600x1200 monitor that still looks nice. I like this form factor, and it's hard to get in these days of HDTV LCDs. Unfortunately, Samsung was known for using shoddy capacitors in that time period, and a few years ago my monitor started blacking out shortly after power up.

          I found a video on YouTube where they showed how to fix my exact model, and I fixed mine with $5 of new caps. Now it's still going strong.

            it would be hard to find someone who does NOT use cheap 'china caps' inside instead of proper panasonic (japan) or nichicon or any of the other *reliable* electrolytic makers.

            badcaps.net is informative for those that have not heard of this 15+ yr old problem in the parts industry. worldwide! china fucked the world on this and we're still paying with blown caps on nearly everything that uses them.

            buy the parts from known places (digikey, mouser, newark, jameco, etc) and you'll get guaranteed real parts, not fakes. even the vendors who build boards tend to use fake caps (bad formula) and they last about a year before they fail.

        True, but much of the same could be said about Apple.

        IIRC Apple's 30" $3000+ monitor shipped with a 1 year warranty (seriously?!). Apple has also, going on for years and years, routinely offered customers to pay extra upfront for warranty/insurance beyond the first year in markets where the law says you have to have more than 1 year of warranty on electronics.

            The thing is though, any discussion about the merits and flaws of one company's offering is always going to become about that and it's competition and Apple is a company that should expect harsh criticism, not so much for it's practices in the west, but for the repeated allegations that it has been looking aside from what's happen

            • Then perhaps you should educate yourself first before making allegations that are untrue? Apple has raised working conditions at their factories far above most others.

              You can do a simple google search and find articles and interviews where factory workers are bitching about not being able to work overtime - a lot of them work for 3-4 years, and take their savings back to their village and can start their own small business, buy a home, and get married.

        Repair it yourself. I fixed an off brand HDTV's power supply awhile back. Repaired, not replaced. Took a few hours, including driving to get some replacement components. The cost of gas was more than the parts. If you repair it yourself, maybe you'll appreciate how long it takes to fix electronic equipment today. Even ignoring the cost of replacement assemblies, a few hours of labor charges and you will have paid for a brand new TV. This issue is not limited to Samsung either.

          Ditto for our 5 year old (at the time) 52" Samsung LCD TV. It wasn't quite the next day, but definitely within a week of us calling them they had a local contractor come by, and he fixed it right in our living room in about an hour, soldering and all. No bill for us, because it was a known capacitor issue, and it's worked great ever since.

          Similar problems with my Samsung monitor - it has serious issues switching between input sources (HDMI, D-SUB) and sometimes would get confused to where it required a shutoff and cooldown for a few min before reuse - a major pain switching between my work and home laptops which use different sources respectively.

      They don't care about your security. On my HTC Android phone, I had to go through and disable a lot of the crap my carrier put in because I was never going to use it

    • And why does it take so long for the carriers to sign off on them anyway? How long does it take to make sure people on stock roms won't be able to tether for free?
    • Well there's your problem. if I had to call up my ISP every time I wanted to patch windows I'd be screwed.

      Part of the problem also comes from the support model. If you have a problem with Windows or your Dell PC, you don't call your ISP and expect them to resolve it.

      Yet in the phone world, if you have a problem with Android or your Samsung hardware you call Verizon/Sprint/etc.

      The last two (European) carriers I worked for would have more than happily passed handset customer support to the OEMs but, unsurpris

      Yeah, they've really worked hard to round up the evasi0n team...

  • F-Secure reports that in the fourth quarter of last year, 96% of all mobile malware was directed to Android. They also report that 0.7% targeted iOS.

    Most users do not have an updated version of Android to update to that is made available from their carriers.

    Trend Micro’s mobile app reputation service has analyzed over 2 million mobile app samples collected from around the world and 293,091 of them have been classified as outright malicious. Almost 69,000 of those were sourced directly from Googl

    • And most of those apps are from unsigned app stores or are sideloaded. Sure, there are some in the main all store, but the problem isn't as big as you're making it out to be.
      • If almost 69,000 were from Google Play, and they have around 700,000 apps total, that would mean that approx 9.8% of the apps in the Google store are infected.
    • I dabble in Android security myself, I just want to point out that every single app I have encountered that Trend Micro flagged has been a false positive warning about an exploit that isn't actually present. The cause of this appears to be that those apps include files or snippets of code also used by some well known exploits, but by themselves are not harmful. Rookie mistake.

      Note that if you search well, you will find various security folk slamming Trend Micro all over the place. As such, I wouldn't put to

  • Not fixing their execution of Android gives them an excuse to replace it with their own proprietary OS (including a locked down boot loader). At the very least, the anti-freedom US carriers would cheer such a move.
  • it's necessary to root your phone in order to change the hosts file.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
