A worm that spreads through low security networks, memory sticks, and PCs without the latest security updates is posing a growing threat to users. The malicious program, known as Conficker, Downadup, or Kido was first discovered in October 2008. Although Microsoft released a patch, it has gone on to infect 3.5m machines.
Anti-virus firm F-Secure says that the worm uses a complicated algorithm to generate hundreds of different domain names every day, such as mphtfrxs.net, imctaef.cc, and hcweu.org. Only one of these will actually be the site used to download the hackers' files. On the face of it, tracing this one site is almost impossible.
Microsoft says that the malware has infected computers in many different parts of the world, with machines in China, Brazil, Russia, and India having the highest number of victims.
