Over 60% of Android Malware Hides In Fake Versions of Popular Apps 111

Posted by Soulskill from the 60-percent?-that's-almost-80-percent! dept.
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."

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

        Well, what you mean is "piracy". It's just people pirating apps, just like they pirate movies, music, software, etc.

        And piracy always exists, though the extent of which is debatable. Figures tossed around can easily be 90% on PCs and Androids, while "walled garden" devices like consoles, iOS, and Steam are far lower - 10% or so by other estimates. (Though, given that the Wii and PS3 are completely "open" at this point, how

        • Steam games are pirated all the time. It has nothing to do with being a walled garden it has to do with usability. If the pirated and non-pirated version are the same thing, or roughly the same thing, people will pirate it, as long as its not too hard to. Thats why even people who pirate xbox games usually have 2 xboxes, so they can legally purchase and play online centered games, which while possible to pirate, provide a vastly different experience than their pirated counterparts.

      • 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.

      • And it doesn't take a rocket scientist to check that box in settings that allows installation from untrusted sources.

        checking the box in android puts up a sufficiently scary warning first. if you aren't going to read that or choose to ignore it, then you'll get what's coming to you. in the same way you will if you enter your root / admin password every time it pops up in windows / mac / linux.

          And nothing you've said convinces me that statement is true.

          All evidence suggests you don't need to be smart to install non-market apps, and the warning solves nothing.
          In fact intelligence is contraindicated for the installation of non-market apps.

      Android needs a trust model. Apps should be assigned to a trust group or level - implicit, trusted, store or untrusted, or one of a user's own making.

      Any action by the app which could cost a user money or reveal private data should be tested against the trust. For example, perhaps SMS messages are outright banned for untrusted apps and are put in a quarantine queue, but for Play store apps maybe domestic SMSs are permitted but not international ones and so on.
