Computer Experts Unite to Hunt Worm

An extraordinary behind-the-scenes struggle is taking place between computer security groups around the world and the brazen author of a malicious software program called Conficker. The program grabbed global attention when it began spreading late last year and quickly infected millions of computers with software code that is intended to lash together the infected machines it controls into a powerful computer known as a botnet. Since then, the program's author has repeatedly updated its software in a cat-and-mouse game being fought with an informal international alliance of computer security firms and a network governance group known as the Internet Corporation for Assigned Names and Numbers. Members refer to the alliance as the Conficker Cabal. The existence of the botnet has brought together some of the world's best computer security experts to prevent potential damage. The spread of the malicious software is on a scale that matches the worst of past viruses and worms, like the I Love You virus. Last month, Microsoft announced a $250,000 reward for information leading to the capture of the Conficker author.
