Smartphone infection rates nearly doubled during the first half of this year, from 0.25 percent to 0.49 percent compared to the second half of 2015, according to a report released today by Nokia.
Nokia provides endpoint malware detection services to major mobile carriers and covers 100 million devices around the world, with the exception of China and Russia, said Kevin McNamee, director of the Nokia Threat Intelligence Lab.
Android is the most targeted device, accounting for 74 percent of the infections.
IPhones accounted for 4 percent and Windows phones did not show up in the statistics, due to their low market share and low infection rates.
The remaining 22 percent of infections were laptops and personal computers connecting via tethered smartphones or WiFi hotspots.
Infection rates varied by month, with a spike in April. Mobile infections hit an all-time high that month, with one out of every 120 smartphones having some form of malware infection, such as ransomware, spyphone applications, SMS Trojans, personal information theft and overly aggressive adware.
