We are more ready for IPv6 email than we may think
In email security circles, IPv6 is the elephant in the room. While the transition from IPv4 to IPv6 is a relatively smooth affair for most of the Internet, and few people will have noticed that a large part of Internet traffic is currently using IPv6, email is still lagging behind: RIPE, Europe’s Regional Internet Registry,…

The road to IPv6 is generally smooth but contains a few potholes
“The report of my death was an exaggeration,” Mark Twain famously said in 1897. It was indeed: Twain went on to live for another 13 years but did eventually die. The same is true for IPv4: reports of the pending ‘ipv4pocalypse’ have been doing the rounds for at least a decade (the most recent one…

Black Hat Europe – day 2
IPv6 versus IDPS, XSS in WYSIWYG editors, and reflected file downloads. After a busy first day , I was somewhat glad that the talks on the second day of Black Hat Europe appealed slightly less to my personal tastes and interests, as this gave me a chance to meet some old and new friends, and…

Researchers demonstrate how IPv6 can easily be used to perform MitM attacks
Many devices simply waiting for router advertisements, good or evil. When early last year I was doing research for an article on IPv6 and security, I was surprised to learn how easy it was to set up an IPv6 tunnel into an IPv4-only environment. I expected this could easily be used in various nefarious ways.…

IETF discusses deprecation of IPv6 fragmentation
Little-used feature could have unintended security consequences. As the Internet is (very) slowly migrating towards IPv6, researchers are reconsidering a little-used feature that allows for IPv6 packets to be fragmented by the sender and reassembled by the recipient. Last year, we published an article on the security implications of the transition from IPv4 to IPv6.…
