We knew that Boot is kind of flooding ID of Yahoo Messenger service. Its can be webcam flood or IM flood. WE also knew that to make boot attack exist, they need an Internet Connection. So the idea to protect being booted is, controlling our internet connection.
That means, if we knew the IP that connected to us, and they seem has send a "suspicious" bandwidth, usually has a huge or uncommon or not normal bandwidth, we can block or stop the connection from those IP (Internet Protocol). If it is urgent, we can also banned the IP or ID.
How to make this happen! Just find the Internet Connection Viewer software and use it as your control bandwidth attack from boot of Yahoo Messenger.
