The Android platform is where the malware action is:
What happens when anyone can develop and publish an application to the Android Market? A 472% increase in Android malware samples since July 2011. These days, it seems all you need is a developer account, that is relatively easy to anonymize, pay $25 and you can post your applications.

In addition to an increase in the volume, the attackers continue to become more sophisticated in the malware they write. For instance, in the early spring, we began seeing Android malware that was capable of leveraging one of several platform vulnerabilities that allowed malware to gain root access on the device, in the background, and then install additional packages to the device to extend the functionality of the malware. Today, just about every piece of malware that is released contains this capability, simply because the vulnerabilities remain prevalent in nearly 90% of Android devices being carried around today.
I believe that smart phones are going to become the primary platform of attack for cybercriminals in the coming years. As the phones become more integrated into people’s lives—smart phone banking, electronic wallets—they’re simply going to become the most valuable device for criminals to go after. And I don’t believe the iPhone will be more secure because of Apple’s rigid policies for the app store.
EDITED TO ADD (11/26): This article is a good debunking of the data I quoted above. And also this:
“A virus of the traditional kind is possible, but not probable. The barriers to spreading such a program from phone to phone are large and difficult enough to traverse when you have legitimate access to the phone, but this isn’t Independence Day, a virus that might work on one device won’t magically spread to the other.”
DiBona is right. While some malware and viruses have tried to make use of Bluetooth and Wi-Fi radios to hop from device to device, it simply doesn’t happen the way security companies want you to think it does.
Of course he’s right. Malware on portable devices isn’t going to look or act the same way as malware on traditional computers. It isn’t going to spread from phone to phone. I’m more worried about Trojans, either on legitimate or illegitimate apps, malware embedded in webpages, fake updates, and so on. A lot of this will involve social engineering the user, but I don’t see that as much of a problem.
But I do see mobile devices as the new target of choice. And I worry much more about privacy violations. Your phone knows your location. Your phone knows who you talk to and—with a recorder—what you say. And when your phone becomes your digital wallet, your phone is going to know a lot more intimate things about you. All of this will be useful to both criminals and marketers, and we’re going to see all sorts of illegal and quasi-legal ways both of those groups will go after that information.
And securing those devices is going to be hard, because we don’t have the same low-level access to these devices we have with computers.
Anti-virus companies are using FUD to sell their products, but there are real risks here. And the time to start figuring out how to solve them is now.
