Most of the malicious software for mobile devices target Google's Android operating system, a new report by Pulse Secure says.
Last year, almost one million individual malicious apps for Android were released, according to Pulse Secure's Mobile Threat Report. That means the number of threats quadrupled in comparison to the year before.
The report is based on data pooled from more than 2.5 million mobile applications, Pulse Secure says.
"There was significant growth in Android malware, which currently consists of 97 per cent of all mobile malware developed. In 2014 alone, there were 1,268 known families of Android malware, which is an increase of 464 from 2013 and 1,030 from 2012," it said.
Apple’s iOS, on the other hand, went through last year basically unscratched. The report said that there were just four iOS targeted attacks in 2014, and the majority of those were designed to infiltrate jailbroken devices.
Pulse said these numbers should serve as a warning to all enterprises, to think long and hard before allowing the Bring your own device policy (BYOD), while those who already have a BYOD scheme should regularly review their security.
"Enterprise networks, while continually hardened at the perimeter, need to apply similar mobile security controls to appropriately deal with the ever increasing BYOD push coming from employees," said Troy Vennon, director of the Pulse Secure mobile threat centre.
"The focus on Android and jailbroken iOS devices by mobile malware developers illustrates that they are actively attempting to exploit mobile devices as the weak link in enterprise security," Vennon added.
