ALERT: First SMS Trojan detected attacking Android phones

Kaspersky has detected what appears to be the very first SMS Trojan attacking Android smartphones. The malicious program called Trojan-SMS.AndroidOS.FakePlayer.a, has been reported to have attacked a number of Android phones.

The Trojan disguises itself as a harmless media player application send via SMS. When the SMS is opened, users are prompted to install a 13KB file. Once installed the program will tell the compromised Android device to send text messages to premium SMS services without the owner’s knowledge. As a result, if your phone has been infiltrated, get ready for a huge text bill at the end of the month.

As with such malwares, prevention is the best measure. If you’ve received SMS from unknown sources with links or attachments, don’t do anything and just IGNORE.

Kaspersky Lab, a leading developer of secure content management solutions, announces that the first malicious program classified as a Trojan-SMS has been detected for smartphones running on Google’s Android operating system. Named Trojan-SMS.AndroidOS.FakePlayer.a, it has already infected a number of mobile devices.

The new malicious program penetrates smartphones running Android in the guise of a harmless media player application. Users are prompted to install a file of just over 13 KB with the standard Android extension .APK. Once installed on the phone, the Trojan uses the system to begin sending SMSs 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.

The Trojan-SMS category is currently the most widespread class of malware for mobile phones, but Trojan-SMS.AndroidOS.FakePlayer.a is the first to specifically target the Android platform. It should be noted that there have already been isolated cases of devices running Android being infected with spyware. The first such program appeared in 2009.

“The IT market research and analysis organization IDC has noted that those selling devices running Android are experiencing the highest growth in sales among smartphone manufacturers. As a result, we can expect to see a corresponding rise in the amount of malware targeting that platform,” says Denis Maslennikov, Mobile Research Group Manager at Kaspersky Lab. “Kaspersky Lab is actively developing technologies and solutions to protect this operating system and plans to release Kaspersky Mobile Security for Android in early 2011.”

Kaspersky Lab recommends that users pay close attention to the services that an application requests access to when it is being installed. That includes access to premium rate services that charge to send SMSs and make calls. When a user agrees to these functions during the installation of an application, the smartphone may then be able to make calls and send SMSs without further authorization.

The signature for Trojan-SMS.AndroidOS.FakePlayer.a has already been added to Kaspersky Lab’s antivirus databases.
