(Telecompaper) Attacks on mobile devices increased 614 percent between March 2012 and March 2013, compared to 155 percent growth a year earlier, according to Juniper Networks. Android devices are increasingly the target. As a percentage of all attacks, Android attacks have risen from 24 percent in 2010 to 92 percent in 2013. This is not due to a large number of vulnerabilities in the underlying platforms. Android remains a target in large part because of its dominant market share and open app ecosystem. Malware is getting easier to distribute. It doesn't take sophistication to turn a quick and easy profit. Privacy remains a concern with legitimate apps.
