====Usage====
1 ] Place minecraft.nse in /usr/share/nmap/scripts/

2 ] Run sudo nmap --script-updatedb

3 ] Run nmap like nmap --script="minecraft" [target] -p 25565 -Pn -n


====How does it work====

The script will use Nmap sockets to execute a "Handshake" with the minecraft server.

Client --> Server: 5 Bytes
|Type|Empty|Name Length|Empty|Name|
 0x02 0x00     0x01     0x00  0x00

The server then sends back a unique session ID which verifies that it is indeed a minecraft server.
