VR Zone writes a new Android Trojan horse is making the rounds. Named SpamSoldier, the virus sends out hundreds of SMS text messages without the user's knowledges. These texts claim to offer free versions of popular games like Angry Birds Space and Need for Speed: Most Wanted, but when installed the app infects your smartphone and spams your contact list to spread itself.
When an individual downloads what they think may be a popular game like Angry Birds Space and Need for Speed: Most Wanted, they actually open up the Trojan installer app which then infects the smartphone. Once installed, the Trojan then works to make sure you become the vector for other smartphones by using your phone to send out the fake messages. There have been a few cases of an actual game install, but the installation was made to cover up and fool the smartphone user as the Trojan sends out hundreds of messages.
... Cloudmark researcher Andrew Conway further notes that users infected phone can and will send out literally thousands of Spam SMS and it will also give out your private information. “A user's phone will be used to silently send out thousands of Spam SMS messages without permission to lists of victim phone numbers that the malware automatically downloads from a command-and-control server.” Conway further added that Cloudmark has seen peak rate of over 500 thousand Spam SMS per day so far.
