Update: RuFraud: European Premium SMS Toll Fraud on the Rise

Update: Since this post was first published on December 11th, Lookout detected 5 additional RuFraud apps in the Market. As of December 13th, 27 applications have been found to contain instances of RuFraud. See below for the full list of apps.

There has been a rash of premium SMS toll fraud apps in the last few months that have primarily targeted users in Europe. These apps have often purported to be downloaders for well-known third party software (often freely available software such as Opera Mobile), and have primarily been found on file sharing sites and alternative markets.

Just this week there have been several waves of a new threat, RuFraud, posted to the official Android Market. The initial batch appeared as horoscope apps with a fairly hidden ToS indicating charges. The initial application activity presents the user with a single option to continue, which is presumed to be an agreement to premium charges that are buried within layers of less than clear links. The Premium Short Codes used could affect users in Russia, Azerbaijan, Armenia, Georgia, Czech Republic, Poland, Kazakhstan, Belarus, Latvia, Kyrgyzstan, Tajikistan, Ukraine, Estonia as well as Great Britain, Italy, Israel, France, and Germany. North American users were not affected as the fraudulent SMS code is gated on the user’s country (as indicated by their SIM).

In the last week we have notified Google of 9 identical applications that were skinned to appear more appealing to potential users: three wallpaper apps for popular movies (including Twilight), and three apps purporting to be downloaders for popular games such as Angry Birds and Cut the Rope. Google responded quickly to our reports and pulled these apps from the Android Market. At the time of removal these applications had only been downloaded by a handful of users, and the severity of the threat was still very low.

Overnight, the fraudsters have posted 13 new supposed downloaders to the Android Market, once again positioned as free versions of popular games. It appears that these apps may have reached a broader audience while published to the market: we estimate upwards of 14,000 downloads of these apps.  Google responded to reports from Lookout and others by pulling these apps from the Market. We’ve deployed an over-the-air update that protects Lookout users from all known instances of RuFraud.

    Hi
    I live in Canada, Southern Ontario to be exact. I was recently charged $30Canadian on my Koodo phone bill for premium text messages that I was sure I did not sent. Does anybody have an idea of how I might be able to recover this money. I have since removed all apps from my phone that are not directly from Google Inc. I have an LG Optimus One.

    @Doug, thanks for your message. You’d mentioned that you had recently seen charges for premium rate text messages appear on your phone bill and you believed it may be RuFraud. You may want to contact your carrier to notify them that you did not send any premium rate text messages. If you have any other questions about about RuFraud, please feel free to contact us: feedback@mylookout[dot]com. Thank you!
