The two pioneers RebBrowser and Wesber where J2ME based applications designed to run on Java enabled phones. However the new kid on the block is called Viver and is designed to run on the Symbian Smartphone platform.

According to Kaspersky this new Trojan was uploaded to file sharing section of a popular mobile device file sharing site. The file was presented as a program that users would actually want such as a photo editor or similar, pretty standard technique for this kind of thing.

Viver sends the messages to a premium rate short number, at a cost to the user of about 177 roubles (almost $7).

The money made by the use of the short code is then split with the individual, mobile provider and content provider.
