Submission + - Scariest IPv6 attack scenarios (

alphadogg writes: Experts are reporting a rise in the number of attacks that take advantage of known vulnerabilities of IPv6, a next-generation addressing scheme that is being adopted across the Internet. Salient Federal Solutions, a Fairfax, Va., IT engineering firm, is reporting real-world incidents of IPv6 attacks based on the emerging protocol's tunneling capabilities, routing headers, DNS broadcasting and rogue routing announcements. The No. 1 attack that Salient Federal is seeing is the result of so much IPv6 traffic being tunneled across IPv4 networks, particularly using the Teredo mechanism that is built into both Microsoft Windows Vista and Windows 7. This vulnerability with IPv6-over-IPv4 tunneling has been known for at least five years, but it is still being exploited.
