Conficker is believed to be the most widespread computer worm
infection since SQL Slammer in 2003.[7] The initial rapid spread of
the worm has been attributed to the number of Windows PCs
(estimated at 30%) which have yet to apply the Microsoft patch for
the MS08-067 vulnerability.[8]
By January 2009, the estimated number of infected computers ranged
from almost 9 million[9][10] to 15 million.[11] Antivirus software
vendor Panda Security reported that of the 2 million computers
analyzed through ActiveScan, around 115,000 (6%) were infected with
Conficker.[12]
Intramar, the French Navy computer network, was infected with
Conficker on 15 January 2009. The network was subsequently
quarantined, forcing aircraft at several airbases to be grounded
because their flight plans could not be downloaded.[13]
The UK Ministry of Defence reported that some of its major systems
and desktops were infected. The worm has 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.[14][15]
On 2 February 2009, the Bundeswehr reported that about one hundred
of their computers were infected.[16]
A memo from the British Director of Parliamentary ICT informed the
users of the House of Commons on 24 March 2009 that it had been
infected with the worm. The memo, which was subsequently leaked,
called for users to avoid connecting any unauthorized equipment to
the network.[17]
Operation
Four main variants of the Conficker worm are known and have been
dubbed Conficker A, B, C and D. They were discovered 21 November
2008, 29 December 2008, 20 February 2009, and 4 March 2009,
respectively.[18]
