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.
Experts warn this figure could be far higher and say users should have up-to-date anti-virus software and install Microsoft’s MS08-067 patch.
Most malware uses one of a handful of sites to download files from, making them fairly easy to locate, target, and shut down.
But Conficker does things differently.
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. More >>
