I even don't know how we can handle a boot that attack in our mobile phone chat. Sometime boot sent to mobile phone are quite dangerous because the mobile phone doesn't have enough memory resource like in desktop or in notebook. I just wondering how we protect our mobile phone. If we got boot while we are in mobile, I believe our mobile phone would be hang.
The only solutions that I found is, just shut down you mobile phone as fast as you knew that you being booted by someone else when you are in mobile. To avoid being booted: make sure you are invisible and not chat with "dangerous" person. Hope this will solve the problem.
