I’ve grown fascinated over the years with various efforts by Internet service providers to crack down on the menace from botnets, large groupings of hacked PCs that computer criminals remotely control for a variety of purposes, from spamming to hosting malicious software and attacking others online. Indeed, botnets problem have become such a global menace that entire countries are now developing anti-botnet programs in collaboration with domestic ISPs.
One of the more unique and long-running examples of this is Japan’s “Cyber Clean Center
,” (referred to hereafter as CCC) a little-known effort by the Japanese Computer Emergency Response Team Coordination Center
(JP-CERT) and a collection of 76 Japanese ISPs covering 90 percent of the nation’s Internet users.
