The use of USB flash drives was banned, as this was believed to be the vector for the initial infection. ДЄn infection of Manchester City Council's IT system caused an estimated ВЈ1.5m worth of disruption in February 2009. On 2 February 2009, the Bundeswehr, the unified armed forces of Germany, reported that about one hundred of its computers were infected. The virus had spread across administrative offices, NavyStar/N* desktops aboard various Royal Navy warships and Royal Navy submarines, and hospitals across the city of Sheffield reported infection of over 800 computers. The United Kingdom Ministry of Defence reported that some of its major systems and desktops were infected. The network was subsequently quarantined, forcing aircraft at several airbases to be grounded because their flight plans could not be downloaded. Intramar, the French Navy computer network, was infected with Conficker on 15 January 2009. Researchers believe that these were decisive factors in allowing the virus to propagate quickly. A second variant of the virus, discovered in December 2008, added the ability to propagate over LANs through removable media and network shares.

Although Microsoft released an emergency out-of-band patch on Octoto close the vulnerability, a large number of Windows PCs (estimated at 30%) remained unpatched as late as January 2009.

While Windows 7 may have been affected by this vulnerability, the Windows 7 Beta was not publicly available until January 2009. The first variant of Conficker, discovered in early November 2008, propagated through the Internet by exploiting a vulnerability in a network service (MS08-067) on Windows 2000, Windows XP, Windows Vista, Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2 Beta. Microsoft analyst Joshua Phillips gives an alternative interpretation of the name, describing it as a rearrangement of portions of the domain name (with the letter k, not found in the domain name, added as in 'trafficker', to avoid a 'soft' c sound) which was used by early versions of Conficker to download updates. The origin of the name Conficker is thought to be a combination of the English term 'configure' and the German pejorative term Ficker (engl. By mid-2015, the total number of infections had dropped to about 400,000, and it was estimated to be 500,000 in 2019.

Microsoft has reported the total number of infected computers detected by its antimalware products has remained steady at around 1.7 million from mid-2010 to mid-2011. In January 2009, the estimated number of infected computers ranged from almost 9 million to 15 million.

Four men were arrested, and one pled guilty and was sentenced to 4 years in prison.Д®stimates of the number of infected computers were difficult because the virus changed its propagation and update strategy from version to version. Дespite its wide propagation, the worm did not do much damage, perhaps because its authors вЂ“ believed to have been Ukrainian criminals вЂ“ did not dare use it because of the attention it drew. The Conficker worm infected millions of computers including government, business and home computers in over 190 countries, making it the largest known computer worm infection since the 2003 Welchia.

It uses flaws in Windows OS software and dictionary attacks on administrator passwords to propagate while forming a botnet, and has been unusually difficult to counter because of its combined use of many advanced malware techniques. Conficker, also known as Downup, Downadup and Kido, is a computer worm targeting the Microsoft Windows operating system that was first detected in November 2008.
