According to Trend Micro's 2012 Annual Security Roundup [PDF file] and 2012 Mobile Threat and Security Roundup [PDF file], the company had identified 350,000 threats for Android by the end of 2012, and expects to see that number surge to one million in 2013.
"The number of Android malware detections spiked in the third quarter from 41,000 to 156,000 samples, according to the firm's research," writes ZDNet's Zack Whittaker. "38 percent was adware, 25 percent stole data, while 22 percent included a malicious downloader. Leading the threat type, however, was a premium service abuser at more than 40 percent."
"Trend Micro's comments follow on from the discovery of several new Android malware strains," notes V3.co.uk's Alastair Stevenson. "Most recently competitor Symantec released a report claiming the Android.Exprespam [malware] had managed to infect multiple thousands of devices two weeks after it began operating."
"The company claims that only a fifth of Android device owners have a security app installed on their smartphone or tablet, which could spell trouble for users in future," writes IT PRO's Caroline Donnelly.
