An Open Network Protocol Question [9:31 am]

Are DNS machines like “bad” money (i.e., “bad money drives out good”)? Or is the network more robust? Or do we need to do something about it? Use of rogue DNS servers on rise — pdf

Mendacious machines controlled by hackers that reroute Internet traffic from infected computers to fraudulent Web sites are increasingly being used to launch attacks, according to a paper published this week by researchers with the Georgia Institute of Technology and Google Inc.

The paper estimates roughly 68,000 servers on the Internet are returning malicious Domain Name System results, which means people with compromised computers are sometimes being directed to the wrong Web sites — and often have no idea.

The conference: 15th Annual Network & Distributed System Security Symposium; the paper abstract — Corrupted DNS Resolution Paths: The Rise of a Malicious Resolution Authority
