With Global Effort, a New Type of Worm Is Slowed
There have been big computer worm outbreaks before, but nothing quite like Conficker.
First spotted in November, the worm had soon infected more computers than any worm in recent years. By some estimates it is now installed on more than 10 million PCs. But ever since its first appearance, it has been strangely quiet. Conficker infects PCs and spreads around networks, but it doesn't do anything else. It could be used to launch a massive cyberattack, crippling virtually any server on the Internet, or it could be leased out to spammers in order to pump out billions upon billions of spam messages. Instead, it sits there, a massive engine of destruction waiting for someone to turn the key.
Until recently, many security researchers simply didn't know what the Conficker network was waiting for. On Thursday, however, an international coalition revealed that they had taken unprecedented steps to keep the worm separate from the command-and-control servers that could control it. The group is comprised of security researchers, technology companies, domain name registrars who have joined forces with the Internet Corporation for Assigned Names and Numbers (ICANN), which oversees the Internet's Domain Name System.
