Citation: 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.

Citation: Social engineering autoplay tricks work on early versions of Windows 7 as well as Vista, according to tests by security researchers. As well as spreading by exploiting a weeks-old Microsoft vulnerability, the Conficker (Downadup) worm attempts to spread across network shares and to infect removable drives, using a special malformed autorun.inf file. [...] 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.
