The number of malicious programs, targeting mobile
devices, increased 6.4 times in 2011 as compared to 2010, says Kaspersky Lab in
its latest mobile security report.


Kaspersky Lab has identified 5,255 new malware

uncovered more new malicious programs targeting mobile devices, than over the
entire 2004 – 2010 period.


During this period, there have been some qualitative
changes in the mobile threats, according to Kaspersky. While unsophisticated SMS Trojans are still the
dominant behavior among all detected mobile threats – their share of all mobile
threats has fallen from 44.2 percent in 2010, to 36.6 percent in 2011, the
report found.

popular operating system for mobile phones. An overwhelming majority of
detected mobile backdoors target Android smartphones.


There has been steady rise in the number of threats
targeting Android during the last six months of 2011.


Spyware was identified as the third-most common mobile
threat behavior.
