SMS-Controlled Malware Hijacking Android Phones

wiredmikey writes "Security researchers have discovered new Android malware controlled via SMS that can do a number of things on the compromised device including recording calls and surrounding noise. Called TigerBot, the recently discovered malware was found circulating in the wild via non-official Android channels. Based on the code examination, the researchers from NQ Mobile, alongside researchers at North Carolina State University said that TigerBot can record sounds in the immediate area of the device, as well as calls themselves. It also has the ability to alter network settings, report its current GPS coordinates, capture and upload images, kill other processes, and reboot the phone. TigerBot will hide itself on a compromised device by forgoing an icon on the home screen, and by masking itself with a legit application name such as Flash or System. Once installed and active, it will register a receiver with a high priority to listen to the intent with action 'android.provider.Telephony.SMS_RECEIVED.'"

      That's not the WHY though.

      They WHY is because people with the 'click' mentality, that is stronger on a mobile, have less fear of adding a possibly infected program. I just don't think the regular Joes of the world have as much awareness of possible malware laden software when it comes to their phone.

      I'm having a hard time understanding why anyone would install the typical greyware apps from a random source outside of the android market... seems pretty risky.

      Easy - piracy. It's the same reason people will happily torrent new release games and applications and run them on their PCs, or download Windows 7 to install on a brand new PC. Hell, malware infested versions of OS X and Photoshop abounded a couple of years ago (they installed a botnet client during the install).

      And face it - a large number of places do not support Google Wallet/Checkout/whatever, especially in places like China. They might now, but once a habit is ingrained, it tends to stay such.

      These sites popped up because of that (you couldn't get the app otherwise) and the end result is they florished and people pretty much got used to the idea of "apps are free" - why pay $2 at Play when your favorite app site has it for free within hours? And if you didn't know of any, your friends who told you what phone to get will steer you in the right direction.

      Even Google's DRM thing isn't that effective - I have seen many DRM-cracker apps available on the torrents that remove it from an APK file.

      And let's not even begin to talk about AOSP-based phones which have to be rooted/hacked to run Play - it's often easier to just download the damn app for free than hack in Play or hope that whatever market came with the device (if any) will carry it.

      For those, perhaps many of these stores have their own market apps and they get preloaded, so users don't know any better. Especially if normal developers also use those stores

      Heck, you should see the iOS piracy sites sometimes - they get overrun with people who buy the latest Apple iDevice and plead "HOW DO I INSTALL?!?!? I NEED IT NOW!!!" long before jailbreaks are released (you have to jailbreak to install the modified installer binary to allow unsigned stuff to run). Of course, without that 15-minute Google refund thing, new apps actually have to be bought and paid for, so app selection is far more limited.

      That, and Apple tends to ensure everywhere they can officially buy devices to access the App Store, Apple is right there willing to sell. (The biggest news is that Apple finally allowed Chinese customers pay in Yuan instead of US dollars).

      Most Android phones will, without rooting, happily allow you to load an .apk archive from the web, or over USB (with debugging enabled in settings), or to add a new app store (enable "unknown sources" in settings). The only carrier I heard of that blocked third party app stores was AT&T, and they caved when their customers started demanding access to the Amazon Appstore. There are millions of people using the Amazon Appstore, and the vast majority have not jailbroken their phones. Even the Amazon specific Kindle Fire allows adding alternative app stores.

      I've used both platforms, and both seem to have an 'approved' appstore and both can access others by jailbreaking (sic). Even the android phones I used were locked down by the carrier to only use the 'real' appstore. I don't see what the substantive difference is in those kinds of cases.

      Apart from what others have posted: the apps in the Google App store are hardly vetted: any developer can post whatever s/he likes, and it is immediately available in the store. Google may remove the app later on if it breaks some of the rules, and I don't think that happens very often. In contrast, Apple checks every version of every app, and only when it is approved it is published.

      I don't understand why anyone would install any non-Microsoft software on a windows computer. It seems pretty risky. I mean there's all sorts of things programs are known for including leaking your information onto the internet, phoning home to the vendor, serving up unwanted ads, and all of that just in legitimate non-malware apps.

      It's even worse on windows machines because when I install an application I don't get given a list of specific permissions it has, such as access to my harddisk, internet, webcam, email client, etc. I literally have no idea what will happen when I click on that .exe file.

      It's about options.

      Android phones come pre-configured to block third-party downloads and they restrict you to the Play Store. Nearly every single one of these reports of Android malware are through other sources, so devices are protected.

      Unlike Apple, though, Android phones give you the CHOICE of whether or not you want to remain under that protection. As simply as checking a box, you can be free to download and run any application you want.

      So Android gives you the best of both worlds, while Apple is simply about controlling everything you do.

      That's like saying that if people have the freedom to choose their own sexual partners, then you can't downplay the existence and risk of sexually transmitted infections. It is a true statement, but the probability of contracting an STI is much higher if you have lots of sex with random strangers that you meet over the internet, than if you have sex with a single known long term partner. And, for many people, the freedom of being able to choose a sexual partner is more important than being protected from the risk of choosing the wrong partner.

    One solution would be to use Google Voice and allow the call to be recorded on Google's system. Then you can access the recording from your phone, your computer, etc. I got my GV number well before you could "port" a number to GV, so I got a new number. I know that is a deal breaker for some folks so look into porting your existing number to GV. It definitely lets you record calls with no problem at all.

    I guess I should point out that the service is still mostly USA only.
