The security expert Joshua Drake of Zimperium, has been commissioned to find the vulnerability and provide more information about Stagefright, and information certainly is not encouraging. Since version Android 2.2 Froyo to the most recent, Android 5.1.1 Lollipop, it is susceptible to succumbing to hacker attack, or what is the same, 95% of Android terminals currently active.
Apparently the security flaw is in the Stagefright library, which can make way for a third party to control 100% of the terminal after it has been infected with malicious software via a video. That is, any communication application that allows sending multimedia files, such as messaging, would be a gateway to the hacker.
However, the biggest problem is in Google Hangouts, which we've heard not many other important security issue recognized by Google itself does. If the currently selected as default SMS application, we need only get the video to infect. Nor is it necessary to open the message, or play the video, or do anything. Our device can be in the hands of another person without our knowledge, and can occur even before we hear the sound of the arrival of the message.
Google has already admitted the problem, curiously there since last April, but has been now that has come to light. The solution would be updated with a security patch, remember all those , 95% terminals in danger, thing that the Mountain View company has already started working, and indeed has already contacted the manufacturers to be at work to combat this problem.
But it would be very naive to believe that all these terminals could receive some kind of renovation, especially the oldest. Drake himself has said that only 20% of current active smartphones may receive the "cure", a figure that hopefully could increase as much as 50%. This depends nothing less than the manufacturers, and the desire to have these to protect users.
