Fortinet's FortiGuard Midyear Threat Report states that the company's FortiGuard Labs observed a 30 percent increase in mobile malware in the first six months of 2013, and is now seeing more than 1,300 new samples per day (h/t SearchSecurity).
Fortinet is now tracking more than 300 unique Android malware families and more than 250,000 unique Android malware samples.
According to FortiGuard Labs senior mobile anti-virus researcher Axelle Apvrille, the increasing prevalence of BYOD policies is making it easier for criminals to leverage infected personal devices to access a corporate network.
"Three years ago, mobile malware wasn’t much of a concern for users or businesses," Apvrille said in a statement. "Most malware at the time targeting smartphones and tablets were nothing more than annoyware such as the Cabir virus or scam software used to commit SMS fraud or replace icons. However, as devices have proliferated, so, too, have cybercriminals eager to capitalize on the growing user base, and our research shows the proliferation of mobile malware will not abate anytime soon."
