Google heavily regulates gambling and gaming apps on its Play Store. It's not hard to understand why. The industry has a long history of gouging and otherwise abusing the people who play their games. In response to the company's heavy-handed regulation of their industry, some app developers have taken to disguise the nature of their unauthorized gambling apps.
On the surface, these stealth gaming apps appear to have other, more mundane functions. However, once you actually install them, their true natures become readily apparent. Researchers found one app that was described as a hub for holiday information but once installed, its only function was to redirect users to a lottery system.
Unfortunately, it's a strategy that pays from the standpoint of the developers. Some of the apps discovered to be little more than shells in the Top 100 lists. Many more than a hundred thousand times, which gives a sense of the problem's scope and scale.
Google's Initiative to Remove Unauthorized Gambling Apps
Google has taken note of the trend and has begun ruthlessly removing any apps that employ this kind of strategy. Unfortunately, about the best the two tech giants can do is clean up the mess after the fact, because many of the app developers making use of this redirect strategy have gotten quite cunning about it. They are deploying an app that appears perfectly normal and then flipping a virtual switch to activate its redirect features once it has been inspected by Google and Apple, respectively. That, of course, makes it virtually impossible to spot on the front end.
To prevent downloading an unauthorized gambling app, carefully read the user reviews. It's certainly not a perfect solution, but it's better than nothing.
