The second most common type of Android threats are spyware applications that capture and transfer sensitive user data to attackers. These account for 19 percent of all malicious samples collected by Juniper's MTC.
Some information-stealing Android Trojan apps discovered during the past year and distributed through drive-by downloads or phishing emails could also pose a threat to enterprise environments, the Juniper researchers said. Data collected from enterprise mobile devices running Juniper's Junos Pulse endpoint collaboration and security software showed at least one infection on 3.1 percent of such devices.
While that figure is not large enough to raise a significant alarm, it is proof that the threat of mobile malware to corporate devices is not only theoretical, the Juniper researchers said. "We expect the presence of mobile malware in the enterprise to grow exponentially in the coming years."
