The Ai.type app was removed from Google Play in June 2019 but still remains on millions of Android devices and is still available from other Android marketplaces. Google told Threatpost it has removed the app from its Google Play marketplace but researchers say it was downloaded on at least 40 million phones worldwide. The app makes suspicious requests to trigger the purchase of premium digital services in the background so users are unaware of the activity. If these transactions had not been detected and blocked, the app could have cost victims as much as $18 million, researchers said.
