The bug is placed in MP3 audio or MP4 video files when you preview or play the infected file the bug is immediately activated and infects your device. What is Stagefright 2.0 and how does it spread? It is a virus that exploits vulnerabilities in Android's multimedia function. (The name "Stagefright" comes from the Android media engine of the same name that contains the vulnerability.) It is dubbed Stagefright 2.0, and dodges existing patches for the earlier versions. The newest version of the bug, just recently appearing, uses MP3 audio and MP4 video files as its host. The first version used MMS and text to infect users. Stagefright and various mutations first appeared in the Spring and Summer.
Adding even more anxiety is a new virus called Stagefright that can be embedded in MP3 and MP4 files.
We are perhaps less vigilant with virus attacks on our phones. We take precautions to minimize the risk - making sure the firewall is up, keeping our antivirus software up to date, and not clicking on scary attachments. Everyone is familiar with virus attacks on PCs and Macs.
