The recent rise of mobile computing has further signaled the need for users to have a good reliable mobile browsers, such as Opera Mini, installed into their smartphones or any mobile device. We believe that it is for this reason that cybercriminals are currently using Opera Mobile as a disguise for mobile malware.

We encountered a website that seems to have been designed to be viewed on a mobile device. The site, which is in Russian, appears to look like the Opera site. It immediately informs visitors that they need to upgrade their version of Opera Mini. Below are screenshots of OperaMini.jar when installed in a mobile phone.

Below is a screenshot of the said site:



All of the links in website lead to the download of the malicious file OperaMini.jar, which is now detected as J2ME_FAKEBROWS.A.
When executed into the device, it checks if the mobile phone uses certain service centers and then proceeds to sending text messages to premium numbers. It affects the mobile devices that support MIDlets — a Java program for embedded devices, specifically the Java 2 Micro Edition (J2ME).

Update as of October 3, 2011, 4:45 AM PST

We were able to find another mobile malware that arrives as a fake Opera Mini installer. This malware however targets Android users. Detected as ANDROIDOS_FAKEBROWS.A, this malware is a premium service abuser — it sends messages to a premium numbers, leaving affected users with unwanted charges.

As advised above, users are advised to install Opera Mini into their devices by directly accessing the Opera site, to avoid being victimized by such attacks.

Really a must from the vendor's site, as these days some 3rd party sites could be trusted or not.

As Opera Mini was very popular by the users, then cybercriminals would take that chance.

To simply put it, this is rogue software for Android.

The site, which is in Russian, appears to look like the Opera site. It immediately informs visitors that they need to upgrade their version of Opera Mini. Below are screenshots of OperaMini.jar when installed in a mobile phone.
Have to admire their dedication and 'hard' work..... I do wonder how many Android users got tricked into installing this rogue app. ,because a 'browser app.' who's asking rights to 'Sends SMS's' should ring a bell..... :)

Although Android users can install an AV App for better protection.

Yeah having any kind of OS I think it is necessary to have AV to prevent anything happening.

Every OS will have a way of being infected until someone comes up with a you beaute idea to stop that, if its ever possible (which i personally think atm it is)

So it's only a matter of time until new OS's get viruses.

I feel its sad that Phones now need Antiviruses... :(

Agreed, it is a waste of the resources on phones because all you meant to do on a phone is to call and text (my favourite :heart: ) and the computer is for big things like games and stuff. Even a laptop would be better.

Of course your phone would. :p
 
It was only a matter of time before the Android got more attention from malware writers etc.. same goes for Mac (how I love that one!). This is the new playground where money is to be made, both from providers and criminals. It's scary to think how the users lacked common sense when installed this rogue browser unaware about the warning signs! Is it not the job of the people in power (the phone providers/makers maybe?) to at least educate new users to use basic common sense.

This is just going to be the start of it, new ways to extort money from users will be happening more often, can be sure of that! And the providers won't give too much of a damn because they're gonna charge regardless saying user error and putting the blame on them.
