un autre virus Windaube: Conficker

The worm is confirmed to have hit a Sheffield hospital and is suspected of infecting UK Ministry of Defence systems, including local area networks on warships.

The Conficker worm is programmed to constantly update itself. The malware is designed to download new code onto infected machines through a large number of different and changing IP addresses, making it difficult to block.
“This is an indication that the worm authors are preparing to carry out a large scale attack in the near future using the infected machines,” said Dominic Hoskins, Country Manager, Panda Security UK.

The same trick, first noticed by researchers at the Internet Storm Centre on Vista, also works on beta versions of Windows 7, researchers at F-secure have discovered.
