Welfare agency Centrelink was one extremely large Australian organisation that didn’t appear today to be worried about the problem, with a spokesperson for the agency saying it was not exposed to the flaw. “The Centrelink gateway uses a DNS product called djbdns, which is not vulnerable to the current DNS poisoning exploit,” the spokesperson told ZDNet.com.au today.
