Well, I suppose it had to happen? There is a new malware affecting devices running Android that surreptitiously sends texts to premium numbers......... a bit like the old diallers.

A malicious app that racks up charges on handsets running Google Android has been discovered.
Security firm Kasperksy Labs identified the app, which is thought to be the first of its kind.
The malicious software is disguised as a media player. However, once the 13KB file has been downloaded onto a handset, it begins sending text messages to premium rate numbers without the owner's knowledge or consent, "resulting in money passing from a user's account to that of the cybercriminals".
