As per report from researchers a second wave of so called stagefright bugs are back which could affect a billion Android handsets. These bugs can help hackers take control of old Android handsets just by sending a message through MMS. Almost all prominent Android phone makers are rolling out security patches regularly to deal with this situation. The importance of software update is becoming more indispensable.
This is considered as the worst Android vulnerability in the history. It could infect Android phones by simply receiving a MMS message even if it remain unopened! Then it would be easy for hackers to target their prey. The new Stagefright 2.0 is specially crafted for MP3 audio and MP4 video files.
