Android.Smsreg.AF is an Android-based App that was developed to trick users into thinking it is a legitimate copy of the popular gaming application, “Flappy Bird”.
One of the first giveaways that the downloaded Flappy bird program is bogus is that while playing games it begins to display the message, “Trial is expired, activation for fifteen thousand!” – This message does not appear in the original game.
Once the application is loaded, it runs the service named ‘vn.adflex.sdk.AdFlexSDKService’, this service collects the following private information from the users device:

Additionally, as the user is engulfed playing the game, Android.Smsreg.AF is silently connecting to a predefined Command & Control (C&C server) to receive further orders and after set time intervals, it begins to send chargeable and costly text messages to a certain number reading, “Flappy Bird would like to send a message to 8748”.
Android.Smsreg.AF also performs an information data breach by relaying all the information supplied above to its server.
