McAfee Singles Out Android for Malware Problems

It would appear that Google’s unfortunately lax approach to vetting apps submitted to the Android store is counting heavily against the platform, as McAfee have released figures showing it is now becoming the biggest target for malware writers.

Nokia’s now mostly retired Symbian operating system still sits in a resounding first place with just under three quarters of all malware, but Android now has a malware problem that is growing exponentially according to the security company’s quarterly threats report

Last quarter the Android mobile operating system (OS) became the most “popular” platform for new malware. This quarter Android became the exclusive platform for all new mobile malware. The Symbian OS (for Nokia handsets) remains the platform with the all-time greatest number of malware, but Android is clearly today’s target.

They say that SMS-sending trojans are still the biggest threat but that trojans that record phone calls to steal sensitive information are now beginning to appear.

While Google’s problems with malware on their Android platform are well known it should be pointed out that this report makes no mention at all of either Apple’s iOS, Microsoft’s Windows Phone or RIM’s Blackberry apps security.  It is odd that the chart they provide doesn’t single out these operating systems at all, merely referring to “Others” at around 10% of the malware problem.

Ten percent of all smartphone malware however is still a huge issue and assuming that 10 percent is split equally three ways (which is just an assumption to highlight a point), while it would only be about 16% of the total malware available for Android, we’re still talking about huge numbers indeed.

Mobile malware is a continuing problem and one I highlight as often as I can.  The reason for this being that this malware can cost you real money in premium rate texts or other mobile charges that can’t occur on your PC.  It’s entirely within the gift of your mobile operator as to whether they will refund such costs, but as the mobile malware problem escalates it will become more and more likely that operators will simply blame the user for downloading and installing the malware (which is fair to be honest) and refuse to issue any credits.

As the introduction to the report the company says…

The third quarter of 2011 offered its fair share of noise and signal: Malware continues to be produced daily at high levels, but we often miss its sophistication—which lies buried beneath the big numbers.  McAfee Labs saw some significant increases this quarter in stealth malware techniques, often referred to as rootkits, especially from the TDSS family. We also observed the continued emphasis on mobile malware, specifically targeting the Android operating system. In fact, this quarter Android was the sole target of mobile malware writers. A true portent indeed!

Unfortunately the mobile malware problem generally is receiving precious little widespread publicity.  While IT Enthusiasts might be increasingly aware of the need to install an anti-virus package on their handsets, the bulk of consumers will still see the their smartphones as embedded OS devices that will just work in the way their TV or toaster does.  They won’t necessarily see it as a device that can be infected and compromised.

While the report is clearly intended to shock, without the exact figures for iOS, Windows Phone and Blackberry’s being released it is hard to guage overall how bad the problem is and to make a judgement over how much more of a target Android is over the next platform.

F-Secure Online Scanner Scans System For Malware

Sometimes you do not want to or cannot install another security software on your computer system to scan for malware. Maybe you do not have the rights to install software on the computer or you have a program installed and do not want to risk incompatibilities.

The alternative is an application like F-Secure’s Online Scanner which can be started from a web browser. This particular application is a Java app which means that the latest Java Runtime Environment (JRE) needs to be installed on the system.

Users can visit the official website to start a scan of their computer system right away. The online application uses up to date virus and threat definitions that F-Secure maintains for all of their products.

When you start the online app you are asked to select a scan mode. Available for selection are quick scan, which only scans the most important files and folders of the system, a full scan or a custom scan. Custom scan can be configured on an extra screen in the program interface.

Here it is then possible to scan all or only selected folders and file types. The program itself will scan for malware, spyware, rootkits using a database of known virus signatures and heuristics to identify unknown threats.

The program then downloads files from the Internet which may take some time depending on the Internet connection. The scan time depends largely on the selected mode and the speed of the system.

The application displays a summary after the scan highlighting potentially malicious files. These files can be deleted from the system and send to F-Secure as a sample (handy if heuristics identified an unknown threat that F-Secure has no information about).

The program is easy to use and comes with enough customizations for advanced uses. I would not recommend relying solely on online scanners for security though, but would recommend them for additional security scans on a regular basis. You can check out our overview of online virus scanners here.
