App store scammers are selling a modified version of Mojang's popular mobile world builder Minecraft: Pocket Edition for Android devices that contains a Trojan, according to anti-virus outfit F-Secure. The fake version of the game, which seems to be aimed at European customers, costs 2.50 Euros - a price too hard for some customers to resist because the real version costs 5.49 Euros.
Once downloaded and installed, the trojan gains control of the user's SMS messaging services, and begins sending premium-rate messages to numbers in Russia. While this earns the scammers money almost instantly, the modified version of the game basically gives permissions to use MSM messaging services to send even more messages and to start signing up for expensive services that the phone owner does not want or need.
The fake version of Minecraft was likely downloaded by deal seekers looking in the darkest places of the Internet for a cracked game for a very low price or even for free.

Interestingly enough, Mojang included code in its game to stop this sort of thing (giving access to the SMS messaging system) from happening in the Android version of the game, but the folks who created the hacked version were apparently smart enough to find a way to get around it.
