Trend Micro discovered a spyware (detected as ANDROIDOS_MOBSTSPY) which disguised itself as legitimate Android applications to gather information from users. The applications were available for download on Google Play in 2018, with some recorded to have already been downloaded over 100,000 times by users from all over the world.
One of the applications we initially investigated was the game called Flappy Birr Dog, as seen in Figure 1. Other applications included FlashLight, HZPermis Pro Arabe, Win7imulator, Win7Launcher and Flappy Bird. Five out of six of these apps have been suspended from Google Play since February 2018. And as of writing, Google has already removed all of these applications from Google Play.
