Following the fake versions of Instagram, Angry Birds Space, and Farm Frenzy apps, we recently spotted a website offering different fake Skype mobile apps for Android. But based on our analysis, these apps are actually malware that run on older Symbian versions or Android devices installed with apps that enable execution of Java MIDlet. Once installed, the malware send messages to premium numbers without users’ consent.
Though these fake Skype apps are marketed specifically to Android users, this malicious .JAR file executes on pre-SIS (Software Installation Script) Symbian phones or certain versions of Android that run Java MIDlet. For Android devices to run Java MIDlet, users must first install an app that enables the device to execute the said file. Typically, these type of apps are available on third-party app stores.

Trend Micro protects users from this threat via Smart Protection NetworkT , which detects and deletes this malicious .JAR file. Access to related websites is also blocked via web reputation service. As an added precaution, users must refrain from downloading apps from dubious websites. Users should also make it a habit to read mobile apps ratings and reviews, to know which apps are safe to download.
