The report noted that enterprise and consumer mobile devices are exposed to a record number of security threats, including a 400 percent increase in Android malware since the summer of 2010.

“Operating system consolidation and the massive and growing installed base of powerful mobile devices is tempting profit-motivated hackers to target these devices,” said Jeff Wilson, principle analyst, Security at Infonetics Research.”

The greatest distribution of mobile malware is through application download, although Wi-Fi worries, SMS trojans, lost devices and risky teen behavior are also mentioned.
