IPv6 neighbor spoofing

Wednesday, 4 February 2009, 11:35 AM EST

IPv4 over Ethernet, by far the most widely deployed LAN technology, has long been plagued by its vulnerability to a simple layer two attack known as ARP spoofing. To oversimplify, ARP spoofing is achieved when a malicious attacker crafts a gratuitous ARP advertisement purporting to be from another host on the LAN, typically the default gateway. By pretending to be the default gateway for a subnet, the attacker can intercept all traffic from the victim host(s) in a man-in-the-middle (MITM) attack.

However, with the (eventual) migration to IPv6, ARP is being phased out, so ARP spoofing should no longer be a problem, right? Wrong. Sort of.
