A Trojan that infects Android devices is behind an increase in text message spam in the US.
SpamSoldier infects smartphones and spews out thousands of SMS messages without the user’s permission. The mobile irritant is primarily spreading through texts that offer free versions of popular paid-for games such as Need for Speed: Most Wanted and Angry Birds Space.
Marks are encouraged to click on a web link in a message that supposedly leads to a game installer. In reality users who open the “installer app” only succeed in infecting their handset with the SpamSoldier Trojan.
