How to make people lose connection?

Hi guys! Sorry for not introducing myself first but i am so interested that i must ask straight away.
I play Total War games for a long time and since the release of Shogun 2 a lot of highly ranked people use tools to make you drop out of the game and "loose connection". I have never used hacks in games but i am just so eager to see how that stuff works and want to try it. So i need help around it and will really appreciate it.

Edit: I have post it to wrong section. It should probably be in a Hack Requests forum

Anyone? If you don't know what i wanted to tell (English is not my native language).
For eg. : I found a 1v1 match, game starts and when my opponent start to lose he kick me from the game somehow and i got notification that i lost connection but actually i was "drophacked"
