Η application Durak Card Game, developed by the "company" Pocket Games Ltd, has been downloaded from the Google Play Store around 10 million times, according to Google. After many complaints from users, security analyst Filip Chytry of Avast started looking into the app and discovered that it has been developed in such a way to serve strange advertisements (adware) in places unusual.
The software waits for 30 days before the launch of aggressive spam with ads, the researcher says. This makes it impossible to link the application installation to that behavior.
“Every time you unlock your device, an ad will be shown to you. It will warn you of a problem, e.g. that your device is infected, for some dating site adult or even porn. This, of course, is a lie," Chytry reports a post on the Avast blog.
“Then he'll ask you to do something. But if you agree, it will direct you to fake pages, which contain apps that try to send SMS messages behind your back, or apps that collect your data your. "
Of course, very worrying is that the application is widely used. In less than three months, 10 has descended millions of times. Avast claims there are other applications, such as an IQ tester, which also serve ads.
Google has already removed the malicious app from the Play Store.
