According to the Business Times, a game available on Google Play called Scary Granny is actually a malicious app. It is able to move around Google security measures and steal user passwords. The Wandera security team found out about the process, which seems very sophisticated and even includes a lurking pattern when the game waiting to accumulate enough players before starting the theft process. It also seemingly provided a full game to its users, allowing for the lurking process to take place.
What's more worrying is that over 50,000 users have the game installed. The app was taken down from the Play Store, but the actual damage is still not known. Hopefully, this is not the start of a very dangerous trend.
