Over 60% of Android Malware Hides In Fake Versions of Popular Apps

An anonymous reader writes "Like any popular platform, Android has malware. Google's mobile operating system is relatively new, however, so the problem is still taking form. In fact, it turns out that the larger majority of threats on Android come from a single malware family: Android.FakeInstaller, also known as OpFake, which generates revenue by silently sending expensive text messages in the background. McAfee says that the malware family makes up more than 60 percent of Android samples the company processes."

    With great power comes great responsibility. I think these pieces keep surfacing because the Anti-Virus companies desperately need to get into this market. They see it is the future and they want a piece of it.

      Unfortunately, that is not true. If it did require smarts there wouldn't be a problem.

      There are far too many people that are duped into downloading from other than trusted sources.
      And it doesn't take a rocket scientist to check that box in settings that allows installation from untrusted sources. Most of these dodgy websites explain exactly what to check and uncheck to get their malware to install. Your average 14 year old teenager as well as your mom can make this change with four screen taps, and install the fake (but free) copy of an app in about 12 seconds flat.

      As always, buying from the Play Store or Amazon presents minimal risk, they will detect the malicious payload it before you even hear about it. (Yes there have been one or two situations where something snuck thru, but these are rare anomalies).

      Its simply greed on the part of handset owners to try to scam a $2.00 app for nothing.

      The Amazon App Store app isn't on Play so you have to sideload by checking the box in the first place. I haven't seen anything from Amazon saying you should uncheck it after installation for your own protection.

      that's because if you uncheck it, amazon app store won't be able to install any amazon app store apps. amazon app store is not a privileged app. all of the apps you install via amazon app store are side loaded.

    Top of article:

    McAfee says that the malware family makes up more than 60 percent of Android samples the company processes.

    End of article:

    If you want to significantly reduce your chance of getting malware such as this one, only install apps from the official Google Play store. That being said, malware has snuck into the store before, so it can happen again.

    So in essence this article is a nearly-worthless scare piece. Unless you're downloading "pirated" versions of (presumably) commercial apps from a shady source, this article isn't relevant. But then, it's a McAfee article, so surprise.

    Technically, not a problem for Android users who stay in Google's walled garden either. Now, we can debate the merits of walled gardens but the article itself is just trying to gin up business for McAfee and citing running unknown sources as evidence of some malware problem when the issue is the user, not the system, since that is off by default.

      The malware sets the phone to use third party SMS gateways
      Those gateways deliver the SMS message to the recipient's carrier, and bills that carrier for the service. You might be none the wiser, but your carrier is paying for that incoming message via bilateral agreements or "Hubbing".

      Hmm.. The malware dials a premium number, and the carrier charges you and sends the money to the holder of that premium number. If we could just track down who that is, we could find out just how much ill-gotten gains they've received. If there was just a way to identify them.

    If the majority of people catching malware are cheap bums who wanted pirated versions and end up paying much more in background messaging, , then it's all good, as far as I'm concerned.

    Some say they first try the pirated versions for any problems before buying the real ones... Here's the thing:

    - most Android apps don't cost more than a cup of coffee. Pretty cheap, considering the long hours of work needed to get some type of decent software on that platform.

    - at Google Play, you can try an app for 15 minutes before getting an automatic cancel of your order.
    http://support.google.com/googleplay/bin/answer.py?hl=en&answer=134336

    15 minutes is plenty of time to check if everything works as intended on your particular phone. If you discover a bug later on, you can always contact the developers who will be more than happy to make their app better on the next version.

    I can't feel sorry for cheaters who get malware . Piracy is one reason (among others) why most Android developers can't make a living selling apps. It's already hard enough when you're not a big company and can't afford the advertising, and find your app on page # 120 on app search...

    Actually, it's what you are saying that isn't true. It's clear you have never been an iOS developer.

    I've had apps rejected 3 times. Once it was a crasher bug that the reviewer spotted that I hadn't. (Mea culpa). Once was a wording issue. And one was a button that in a certain edge case should have been disabled and wasn't.

    In each case the problem was spelled out clearly. Clearly I had to stop that crash, disable that button in that certain circumstance, and change the wording. Now of clearly they didn't tell me what wording I had to use - that's my job. They just told me what was wrong with the wording I'd originally used.

    Apple App Store has 700,000 apps on it. Most of those apps have had several revisions. Each and every revision of those apps has been through the app review process. The examples you've read stories about are a handful. A process gets it right hundreds of thousands of times more often than it gets it wrong doesn't sound broken. Especially when there's opportunities for resubmission and appeal.
