Mobile devices are no strangers to the virus, and that’s one thing that everyone should have tucked into his head. Smartphones are computers that can be infected by any malware so you have to take the same care with our desktop PCs. So today we reported a Trojan discovered in several adult websites that is installed in three stages to avoid detection by antivirus. It’s called SMS Stealer.

This Trojan, called SMS Stealer but has been detected under different names by different security companies, it is often found in several sites of adult content. The bait to install the application is a video player that will allow better view videos from the web itself. That is, trick users to download and install this special video player on your mobile phone.

Well, once this is done the Trojan installs itself three more applications on the terminal itself advertised with different pornographic topics and in turn these installed another wave of applications as open. That is, it is a Trojan installed in three stages.

Divide the Trojan behavior in different apps

The technique of the three stages can divide malicious behavior in order to make it harder to detect and remove virus. Its main function is to intercept and send SMS which is then charged to the user. That is, hackers use these applications to send messages to premium subscription services and then intercept the verification code these services refer the user to complete the registration process.

The problem for users is that only the first application requires users to grant permissions for sending SMS and so users do not suspect other applications that are also doing the same. “The application uses the concept of outstanding intentions, allowing other applications can use the permissions of the parent application to execute a predefined portion of the code, “says a researcher at security firm Zscaler.

Therefore always you have to be very careful with the applications installed outside the official store Google. It is best not to, but if we do, always good to have an antivirus program that allows us to improve the security of our terminal. If not, we can pass things like this or worse. The phones are already as PCs and we must take care as such.
