Have you ever wondered who SMSes porn and astrology lines at $9.99 per message? Your phone! A new Trojan for Android adds a small Android extension that sends SMS messages to “premium numbers,” charging the users a few dollars per message.

Kaspersky has identified it as Trojan-SMS.AndroidOS.FakePlayer.a and it only works on Russian networks. It doesn’t seem like the brightest or most dangerous Trojan ever written – you obviously have to download it yourself, probably as part of another package – but it’s still pretty scary stuff, especially if you have no interest in astrology.
