F-Secure: Android Accounted For 97% of All Mobile Malware In 2013

An anonymous reader writes "Back in 2012, Android accounted for 79 percent of all mobile malware. Last year, that number ballooned even further to 97 percent. Both those data points come from security firm F-Secure, which today released its 40-page Threat Report for the second half of 2013. More specifically, Android malware rose from 238 threats in 2012 to 804 new families and variants in 2013. Apart from Symbian, F-Secure found no new threats for other mobile platforms last year."

    This is what you get running unsigned code from anywhere people! The last 30+ years of malware on Amiga, DOS, Windows, Unix, Linux, etc. should be a lesson. Trust code to execute by default and this is what you get. Rely entirely on the end user to determine whether or not code is legitimate, and this is what you get.

      The title of the article is "F-Secure: Android accounted for 97% of all mobile malware in 2013, but only 0.1% of those were on Google Play".

      Essentially all of the Android malware comes from non-Google app stores, or sideloaded APKs. And with respect to the malware that does manage to make it into the Play Store, F-Secure says "the Play Store is most likely to promptly remove nefarious applications, so malware encountered there tends to have a short shelf life.”

Knowing this the designers decided the only access controls would be take it or leave it DEMANDS made by APPLICATIONS. This is why Android is insecure by design... it totally and utterly fails to protect the USER in the most basic rudimentary way possible.

This is not malware at all and off topic for the discussion, but let's cover it. This is restraining applications that want to be more than the end user wants them to be, giving the end user full disclosure when an update seeks to do things it didn't do before. You make it sound like a bad thing, when in fact it's an enhancement above the other methods of application security provided by the system that empowers the user to be more restrictive than any algorithm could appropriately be.

      No, it's the user who is getting exploited. And that's the point: the average end user (and in the case of more advanced malware, the average technical user, or in fact anyone who hasn't been able to audit the application source code) is vulnerable to this sort of malware.

      Using an app store plus code-signing enables a trusted third party to audit the code, and sign it as approved to run on the device. In the case of appliances like phones, tablets, etc., expecting your typical non-technical user to audit source code for every app they install is unrealistic.

      In the case of loading an app onto an android device from a third party, it's a crap shoot. You are basically guessing that the particular installer you are running is not a trojan. You may be basing that on app reputation, etc. but have no real clue whether or not it has been time-bombed, for example. You're guessing, flying blind.

      It's pure luck and lack of true malicious developers on the platform that the android malware situation right now is not a LOT worse. And it's nothing to do with exploiting the JVM, kernel or whatever - it's purely due to the end users of consumer devices not being interested in becoming security experts. They are (rightly so) not interested in it.

      Signed-code only, whilst being restrictive in what you can run takes that burden off the user. If the user truly wants to run something that the vendor will not sign, in the case of iOS it is simple enough to get a developer subscription and compile it from source yourself.

    Apple always charges $100 to put an app in the store, so malware has to make at least $100 before it is discovered or the person who put the malware on the store loses money.

    And according to TFA, almost all of the malware was side-loaded. Almost none of the malware came from the Google Play store. Thus, Android gives me the advantage of the walled garden, while still being more free than iOS.
