As you know, around 95% of Android devices are vulnerable to new malware. The vulnerability is called "Stagefright" because through it a hacker can get full control of your device. For this they need only send a video by MMS through Hangouts, and it is not even necessary that we open it. If you have enabled the option "Auto retrieve MMS" in the application, you'll be infected.
Zimperium was the company responsible for discovering this security flaw, and has been quick to send Google everything necessary to solve the problem as soon as possible, in addition to getting down to work with other companies so that they can launch updates on the shortest possible time. However, for now, only Google Nexus 5 and Google Nexus 6 may say they are completely safe. To other devices we have to continue waiting for the update to the patch, and it seems that the Samsung Galaxy S6 are as follows.
In this video, we demonstrate how easy it is to gain control of an Android device exploiting this vulnerability:
Once installed, you only have to press the yellow button that says "Begin analysis", and within seconds the results will come. Since 95% of Android is likely to be infected, it's natural to give us results in our Android as vulnerable, but be careful, because this does not necessarily mean that is affected. Only that, it is vulnerable.
The truth is that it is unclear how useful the application is, so maybe a simple question via advertising. That is, it is an application to find out what we already know. Once we have the results, we displayed a message with a contact link to Zimperium. Anyway, at least it seems that Google and other companies are ready to solve the problem. The best we can do while we wait for the patch, is taking steps to protect against vulnerability.
