Android has a lot of malware available, and continues to adopt more. How long will iOS be malware-free?
iOS has been the most secure mobile operating system for many years. People will deny that, but to an extent it's true. An unjailbroken iPhone has no way of installing applications outside of Apple's App Store, and the applications that get into the App Store are topped with a layer of extreme scrutiny by the people who accept and reject the applications into the App Store. Android, on the other hand, can install applications that are not on the Android Market by either remote intentions or by the user themselves. Because of this, Android has the better chance of being infected by user ignorance. iOS users have it good in that applications which are accepted into the App Store are checked thoroughly for functionality. There have been rare cases when applications 'with a little extra' have been sneaked into the App Store. Such cases include PayUpSucker which would let you tether your data for free even though it claimed to be an I.O.U. application. Even though this has happened, users weren't complaining because it didn't do anything bad – the developer added the functionality to give people who do not jailbreak their phones the opportunity to have a way to use their data freely.
Android on the other hand, has a myriad of drive-by-malware no matter where you turn. As Phillip Swanson reported not too long ago, Android malware hits are up by 472% since July while iOS remains untouched. So what does this prove?
Not much, but it is hard data. It shows that Android, being a popular operating system and also being easy to install things on, is an easy target for hackers with malicious intentions. Security expert, Bruce Schneier, doesn't see iOS being secure from malware forever. As hackers become more and more accustomed with the way that iOS works and as long as jailbreaking is legal, hackers will learn more and more about what makes iOS tick. As hackers become more and more able with their abilities, they can turn to the dark side. That's not to say that jailbreak hackers will do so, we trust them with our devices because they hack for the greater good of all of us. But, there are evil hackers out there. Bruce Schneier had this to say about iOS and malware:
