'Android' is the platform designator used by F-Secure to identify programs that run on the Android operating system developed by Google.
Developed for use on mobile devices such as smartphones and tablets, the Android operating system has rapidly developed into the most popular platform for these consumer items.
Predictably, this has also sparked the rapid development of malware on the platform, including:
The majority of Android malware requires a user to actively install and launch an app in order to be affected. In such cases, attackers typically create an app that looks enticing or legitimate, but silently performs malicious actions in the background. Quite often, the app may be a legitimate app that has been hijacked and alter for malicious use (in which case, the app is said to be trojanized).
In some cases, the malicious app may exploit a vulnerability in the Android operating system in order to perform its malicious actions.
