H6Proxy: ICMPv6 Weakness Analysis and Implementation of IPv6 Attacking Test Proxy

Although IPv6 protocol has considered and implemented more security mechanisms compared with IPv4, there are still many security threatens in IPv6 networks. Being one of the key protocols in IPv6, the Internet control message protocol (ICMPv6) suffers from severe security risks. In this paper we construct an IPv6 attacking test system H6Proxy exploiting the ICMPv6 unreachable message, which shows that the security of IPv6 protocol is still very weak.
