Overall I like our title (currently "Android devices can be fatally hacked by malicious Wi-Fi networks") but "fatal" has a specific meaning (causing death) so isn't there some other word in place of that one that could be used here? It is certainly evocative of how dire this is but I feel like a different word might be more specific without losing gravity.
