Stagefright is a critical vulnerability of Android that attackers can take advantage of by using special Multimedia Messaging Service (MMS) messages.
What makes the vulnerability especially annoying is that it can be passively exploited on devices. All it takes is sending a malicious MMS to one device running Android and the hacker can gain access to the system with administrator privileges.
The hacker on entering the system can delete the MMS from your device before you open it. So you may never understand that someone else has taken control of your device.
So if you are not sure if your device is affected by malware, you can use a Stagefright detector. The application is in Google Play and you can download it free.
After installation, by clicking on the "Begin Analysis" button, the application will scan your device in a few seconds.
The results will appear on the same page, so you will know whether your device is vulnerable or not.
The application may also instruct you to upgrade your operating system for vulnerability protection.
The Stagefright app Detector ελέγχει για την ευπάθεια αλλά δεν λαμβάνει υπόψη τις ρυθμίσεις των μηνυμάτων σας. Αυτό σημαίνει ότι θα καταλήξει στο συμπέρασμα ότι η συσκευή σας είναι ευάλωτος στην ευπάθεια Stagefrιght, ακόμη και αν έχετε απενεργοποιήσει την automatic recovery of MMS in it.
