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.
