Fake apps which are in fact premium rate SMS Trojans have been discovered in Google's Android Market.
The Trojans were uploaded by a developer going by the name of "Lagostrod." The Trojans were disguised as free versions of popular apps such as Angry Birds and Cut the Rope.
These apps were quickly banished from Google's Android Market but more Trojanized apps by developer "Miriada Production" appeared (these have now been removed). Site such as AppBrain still list the apps.
So far premium rate SMS Trojans have only targeted Russian users, but these apps target users from 18 countries, including the UK.
If you've downloaded any of these apps, remove them immediately.
