Today's world most critical challenges are unknown Malware.Moving end user data via different channel. Mobile computing is the mostly effected area.
Current Malware are replicate itself with uTube video, Photo share via WhatsApp.
I personally observed that Android 5.0 getting hang while opening a particular video and finally auto reboot phone.
Every instances I observed it is the same video file. Using McAfee Security for mobile but this AV unable to detect it.
Remove that video file and my issue successfully resolved now.
This is one instances i share in this community. I would request please share such topic which may only solve by zero day attack signature.
