Help Net Security reminds us that most mobile phone users still don’t have a mobile AV solution installed on their devices making. This makes it hard to gauge just how many of them have been hit by mobile malware. To overcome this fact, Microsoft (MSFT) researchers observed that mobile phones often get synched with the users’ computers. Also, users often use their computers to search for mobile apps on third-party application markets and file-sharing sites. These habits allow mobile malware to occasionally end up on their desktop/laptop computers and gets detected by desktop anti-virus software.
Researchers at the Microsoft Malware Protection Center (MMPC) were able to use thes detection to get an idea of what malware attacks the various mobile operating systems. The MMPC found was that Symbian users’ devices are getting hit with a disproportionately bigger number of threats than those targeting other operating systems. In August 2011, Microsoft detected around 42,000 of them.
Malware attacks
Microsoft’s Marianne Mallen says that Symbian-specific malware seems to be evolving and Zeus-in-the-mobile (“ZItmo“) and SpyEye-in-the-mobile (“Spitmo“) are the most recently detected malware and arguably the most dangerous for the user.
The Sun Oracle (ORCL) Java ME platform takes second place in the MSFT research, with nearly 24,000 threats detected in August 2011, mostly apps sending text messages to premium-rate numbers.
The MMPC found that Google‘s (GOOG) Android malware numbers were rather low when compared to Symbian and Java ME platforms. There were around 2,800 hits in August, but have been steadily rising since February. Much of the Android malware uses privilege-escalation exploits to install itself or other components on the device without having to ask the user for permission.
At the end of the MSFT list are Apple (AAPL) iOS and Research In Motion (RIMM). No new threats for Apple’s mobile OS have been discovered this year, and the total number of threats detected in August was around 590. RIM brings up the rear with only 5 malicious apps detected during that month and can boast of only one completely new threat springing up for it this year:.
Ms. Mallen’s advice to mobile users is to scan applications downloaded when possible, even when it’s already on a mobile device. Ms. Mallen says that even apps from the official app stores, may have been repackaged with malware that can run stealthily without the user being made aware of the underlying payload,” she points out. “The payload can include data-theft, silent SMS-sending in the background, and downloading and installing of other malware components, among other things. This malware (or links to it) could also be spammed or sent through email, using social engineering to entice the user to download a copy of the malware onto the desktop.”
