New study: DNS spoofing doubles in six years ... albeit from the point of naff all

Boffins from the University of Southern California's Information Sciences Institute have crunched six years and four months of data, and found that DNS spoofing, while uncommon, has doubled during that time.

In their paper, the US academics explain, "DNS spoofing can be accomplished by proxying, intercepting and modifying traffic; DNS injection, where responses are returned more quickly than the official servers; or by modifying configurations in end hosts."

Heidemann pointed out that Indonesia and Iran had the largest portion of vantage points - specifically, public DNS resolvers - exhibiting spoofing.

"There have certainly been cases where DNS spoofing has been used maliciously," he said.

Heidemann said the research paper doesn't identify specific reasons for the rise in DNS spoofing but suggested it follows from the growing importance of the internet around the globe.
