A lot of apps from the Android-Market were determinted to subscribe premium services, if the smartphone user was in China. The evil apps send automaticly SMS messages which subscribe a premium service.
The user wouldn't notice that because this evil app will delete the text message before he is going to read it.
Affected are the following: Match, 3D Cube horror terrible, ShakeBanger, Shake Break, Sea Ball, iMine, iCalendar, LoveBaby, iCartoon and iBook.
Google has reacted and deleted those apps from the market.
This wasn't the first time when Google deleted apps from their market. Last March they deleted 50apps from their store.
