Windows Mobile Trojan frags gamers

Premium-rate calls on the sly

Scammers have hidden a nasty surprise for users who downloaded doctored copies of a Windows Mobile game.

Hackers adapted a demo version of 3D Anti-Terrorist Action to include a Trojan that makes premium-rate calls costing around US$6 a minute on the sly. Doctored copies of the Counter-Strike-alike game are designed to call premium-rate phone numbers in the Antarctic, the Dominican Republic and Somalia, leaving users none the wiser until they received whopper mobile phone bills.

The Terdial-A Windows-CE Trojan was first identified in March but has recently made its way onto several sites hosting Windows mobile apps, prompting a fresh warning from gaming site gamepron.com.

It adds that even legitimate versions of the application lack engaging gameplay.

Screenshots of the application, along with extracts from a UK victim's email, can be found in a blog post by Sophos here. The net security firm reckons a Russian-language speaker wrote the malware behind the attack. ®
