Visualizing the DNS ‘Cache Poisoning’ Attack
Dan Kaminsky has revealed the full details of the much publicized DNS flaw, known as “cache poisoning.”
The good news is that most vendors have already pushed out patches and you can watch the visualization above to see them propagate across the web. Red stands for vulnerable servers, yellow for patched but with NAT issues and green means the server is okay.
If you haven’t been keeping up with the hoopla, here’s Kaminsky’s description: “recently, a significant threat to DNS, the system that translates names you can remember (such as www.doxpara.com) to numbers the Internet can route (66.240.226.139) was discovered, that would allow malicious people to impersonate almost any website on the Internet.”
