As smartphones and tablets are taking a major role in our daily lives as well as at work, hackers have taken note. The most recent Threats Report by McAfee found that the number of mobile malware has gone through the roof in the second quarter of 2012.
             
With more than 8,000 mobile malware samples being spotted in Q1 2011, the security software company commented that it was an explosive number comparing to previous data. Yet, this figure still pales a bit in comparison with that in Q2 2012: The latest report shows that the total number of mobile malware in the company’s database has soared to over 13,000.

Among operating platforms, Android is still found to be the most targeted platform for writers of mobile malware. The number of new mobile viruses identified in this quarter dropped slightly. However, Android users may not be happy with the fact that virtually all of the new ones were directed at the open-sourced OS. And there are a few mobile viruses particularly worth our attention:

• “drive-by downloads”: a new attack vector dropping malware on your Android mobile when you visit a site;
• Android/Twikabot: a new mobile botnet client using Twitter to control your device; and  
• mobile ”ransomware”: malware which extracts funds from unsuspecting victims by holding their computer or data hostage.

Other malware identified includes SMS-sending malware, spyware and destructive Trojans.

The above figures as well as those virus names may sound pretty scary. Well, take a breath and don’t panic. There are still cures for our phones. And we found this suggestion by McAfee Labs quite useful: install software only from the official markets. This should greatly reduce the risk of compromising your Android device since malicious applications are less likely to be found on official markets.
