Cyber criminals are increasingly targeting mobile devices as they look to exploit consumer ignorance of potential security risks associated with smartphones and tablet PCs, reports the Financial Times. The amount of malicious software designed specifically to target mobile devices rose 46 percent in 2010, says a report by IT security group McAfee. The report also found that whereas hackers tended to focus on finding breaches in Nokia’s Symbian operating platform, Apple’s iOS and Google’s Android systems were increasingly targeted as they gained market share.
