Android mobiles hit by spam virus

Cyber-thieves are using games including Angry Birds to turn Android phones into spam-sending drones.

Phones have been infected with spam-forwarding software that hid inside free versions of popular Android games.

Once installed, the booby-trapped app contacts a web server for a list of phone numbers then starts sending junk text messages to them.

Angry Birds Space, Need for Speed Most Wanted and many other games have been used in the attack.

The first stage of the campaign to recruit phones to act as spam relays. It involved sending out thousands of messages supposedly offering people free versions of popular Android games, said network security firm Cloudmark in an analysis of the SpamSoldier attack.
