From WIKI:

Conficker, also known as Downup, Downadup and Kido, is a computer worm that surfaced in October 2008 and targets the Microsoft Windows operating system.[1] The worm exploits a known vulnerability in the Windows Server service used by Windows 2000, Windows XP, Windows Vista, Windows Server 2003, Windows Server 2008, and Windows 7 Beta.[2][3][4] The latest variant will begin checking for a payload to download on April 1, 2009.[5

Operation
The Conficker worm spreads itself primarily through a buffer overflow vulnerability in the Server Service on Windows computers. The worm uses a specially crafted RPC request to execute code on the target computer.[6]
When executed on a computer, Conficker disables a number of system services such as Windows Automatic Update, Windows Security Center, Windows Defender and Windows Error Reporting.
It receives further instructions by connecting to a server. The instructions it receives may include to propagate, gather personal information and to download and install additional malware onto the victim's computer.[7] The worm also attaches itself to certain Windows processes such as svchost.exe, explorer.exe and services.exe.[8]
The worm seems to implement some of the ideas presented by Fucs, Paes de Barros e Pereira at the Blackhat Briefings Europe 2007, specifically: digitally signed additional payload, use of PRNG for communication and P2P communication.[9]
