Now the question is, can one easily block all of doubleclick.net by 127.0.0.1 in the hosts file on a wincrash box? They appear to have ad, ad2, ad3, m2, m3.doubleclick.net. Anyone know what hosts to list??? (ie: ad2, ad3 ... to ad<x>???) ----- Original Message ----- From: "Henry Linneweh" <hrlinneweh@sbcglobal.net> To: "Sean Donelan" <sean@donelan.com>; <nanog@merit.edu> Sent: Tuesday, July 27, 2004 17:10 Subject: Re: ad.doubleclick.net missing from DNS?
While I disagree with the method of the attacker, I can understand the reasoning behind an attack on a company that is considered a spyware company, doubleclick certainly has turned up more than once on my version of spybot as a site to block.....

DoubleClick spokeswoman Jennifer Blum said the attack targeted the company's domain name servers (DNS) -- machines that help direct Internet traffic -- causing "severe service disruptions" for all 900 of its customers. Blum said the outage was caused by a distributed denial-of-service attack, in which hackers use the firepower of thousands of hijacked computers to flood a Web site with so many bogus Web page requests that it renders the site unavailable to legitimate users. [...] The FBI is not investigating the incident because DoubleClick has not filed a report, said bureau spokeswoman Megan Baroska.
