About IPv6 DDoS attack and RA flood attack – 001.

About : IPv6 DDoS attack using router flooding .
This is extremely dangerous! Why? Because: A single device can instantly stop all the Windows machines on a Local Area Network.
See how you need to disabling router discovery:

C:\>netsh interface ipv6 show interface

Idx     Met         MTU          State                Name
---  ----------  ----------  ------------  ---------------------------
  1        4275  4294967295  connected     Loopback Pseudo-Interface 1
 15        4230        1500  disconnected  Wi-Fi
 36          20        1480  connected     Broadband Connection
 16        4230        1500  disconnected  Local Area Connection* 11
 19        4275        1280  disconnected  isatap.{___....___}
 12        4245        1500  connected     Ethernet
 20        4275        1280  disconnected  isatap.{____....__}
 17        4265        1500  disconnected  Bluetooth Network Connection

I changed my real … with {___….___}.
Next step is about : netsh int ipv6 set int “[int number]” routerdiscovery=disabled
Let’s try one example :

netsh int ipv6 set int "1" routerdiscovery=disabled
Ok

This will disable Loopback Pseudo-Interface 1. No need if you dont test your software with “Loopback” or your OS don’t need it.
Also can do this :

netsh interface ipv6 set interface "Local Area Connection" routerdiscovery=disabled

this will turning off Router Discovery on all servers and any other machines that do not need Stateless Autoconfiguration.
System administrators can disable router discovery. The machine will discard any RA packets.
Also RA flood attack is appeared in many operating systems ( see this video to understand more…)

Also you can see demostration from Sam Bowne new ra flod attack

	// Use this for initialization
	void Start () {

	}
	
	void Update () {
		if (timeRemaining > 0) {
			Debug.Log("Waitting..."+timeRemaining);

Remove tunnels adapter show by ipconfig command.

According to technet.microsoft website about IPv6 for Microsoft Windows:
IPv6 in Windows XP and Windows Server 2003 uses the “Automatic Tunneling Pseudo-Interface” for encapsulating IPv6 packets with an IPv4 header so that they can be sent across an IPv4 network. By default, IPv6 configures a link-local Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) address on the Automatic Tunneling Pseudo-Interface. The link-local ISATAP address has the form fe80::200:5efe:w.x.y.x or fe80::5efe:w.x.y.x, in which w.x.y.x is an IPv4 address assigned to the computer.
You can remove this with this windows command:
