Ever heard of a Denial of Service attack or DoS? You probably have, but what about using it against a popular video game, Minecraft DoS'ing (or MCDoS'ing for short)
As you can see it appears that the DoS attack literally denies service to the players and kicks them off.
It does this by overflowing the server's port, in this case 19132 (Standard Minecraft PE LAN Server).
If you have the online version here which also contains the full source code, You can multiple tabs open, meaning you have a network of virtual hosting machines DoS'ing the server at the same time causing a more devastating attack, if you have enough tabs open for clients open you can temporarily shut down the server all together.
