A new study has found that Google’s (GOOG) mobile operating system is targeted by hackers far more than any other mobile platform. Security firm F-Secure found thatAndroid accounted for 79% of all mobile malware in 2012, an increase from 66.7% in 2011 and 11.25% in 2010. Apple’s (AAPL) iOS platform on the other hand has remained nearly untouched throughout the years. Malware on the operating system, which is the second most popular among smartphone buyers, was found to account for only 0.7% in 2012. The firm also found that Android saw a significant increase in malware at the end of the year, accounting for 94% of all threats in the fourth quarter. Most malware, however, is found in emerging markets. A majority of mobile users in Europe and the United States will never be affected but should still be cautious of suspicious text messages, links and emails. F-Secure’s graph outlining mobile malware threats is posted below.
