More than 65,000 mobile malware threats were detected in 2012, an increase of 163 percent over 2011, according to a study released this week.
According to a new security report released by NQ Mobile Inc. (PDF), nearly 95 percent of all mobile malware discovered in 2012 targeted the Android OS. The top three methods for delivering malware in 2012 were application repackaging, malicious URLs, and SMiShing.
NQ Mobile estimates that these forms of malware helped infect an estimated 32.8 million Android devices in 2012 -- an increase of more than 200 percent over 2011.
"In the first quarter of 2013, mobile malware threats continued to grow and have become smarter," NQ Mobile says. "In February of this year, a new type of mobile malware was discovered that could jump from an Android device to infect a PC when they were connected via the USB port." Only a few Android devices were infected, the company says.
NQ Mobile Security Labs, a team of more than 250 mobile security professionals around the world who monitor the mobile landscape for new malware threats and mobile hacking methods, has also observed increased collaboration between mobile hackers and cybercriminals, the report says.
"These unlawful collaborations can have disastrous effects on consumers," NQ Mobile states. "Mobile hackers are using malware to capture consumers' private information, and then selling this information to cybercriminals, who are in turn using social engineering tactics to gain access to the consumers' finances."
The top five markets for infected mobile devices were China (25.5 percent), India (19.4 percent), Russia (17.9 percent), the United States (9.8 percent), and Saudi Arabia (9.6%), the study reports.
Sixty-five percent of malware discovered in 2012 falls into a broader category of Potentially Unwanted Programs (PUPs). PUPs include root exploits, spyware, pervasive adware, and Trojans (surveillance hacks).
NQ Mobile estimates that more than 10 million devices have already been infected in the first quarter of 2013.
