Conficker Worm Targets Microsoft Windows Systems
Original release date: March 29, 2009
Last revised: --
Source: US-CERT
Systems Affected
Microsoft Windows
Overview
US-CERT is aware of public reports indicating a widespread infection of the Conficker worm, which can infect a Microsoft Windows system from a thumb drive, a network share, or directly across a network if the host is not patched with MS08-067.
If a user is unable to reach either of these websites, a Conficker infection may be indicated (the most current variant of Conficker interferes with queries for these sites, preventing a user from visiting them). If a Conficker infection is suspected, the user should run the Microsoft Windows Malicious Software Removal Tooland install updates available from the Microsoft Updatesite.
