This diary will be updated as more information becomes public. Updates are highlighted in green. Please use the URL: "http://www.dshield.org/conficker" to link to this page.

In an effort to provide YOU the end-user the ability to educate your self on this threat we will be posting as much information as possible, from as many sources as possible. This may lead to redundancies in the data that is fallible but we are hoping that this will allow you to pick and choose the information, removal tool, and more importantly your own path when mitigating Conficker. Be careful about help and removal tools offered from unknown sources.

Our own diaries to the topic can be found here: http://isc.sans.org/tag.html?tag=conficker
