While I agree that it is reasonable to expect trending towards an alarmist reaction, there are significant enough similarities between DuQu and Stuxnet to suggest that the authors of the former had access to the source code of the latter. If you read the W32.Stuxnet Dossier (http://www.symantec.com/content/en/us/enterprise/media/secur...) from Symantec it pretty objectively articulates the complexity and sophistication of the creation of Stuxnet. I personally don't think it's an alarmist opinion to believe Stuxnet had national interest behind it, and so am pretty wary of DuQu until more information is uncovered.

There are significant similarities between DuQu and Stuxnet, agreed. However, I don't think that necessarily means they share the same author. Stuxnet has been widely distributed and analysed. There are a lot of smart people/groups in this world and one of them could have decided to use it as a starting point for other purposes. I also agree that it isn't alarmist to believe Stuxnet had a national interest behind it, there has been significant research and evidence to support that, but that is Stuxnet, not DuQu. Again, since DuQu came after Stuxnet it is quite possible that another group is responsible for DuQu that is not related to the original. Although, I do also think that being wary of DuQu until more information is uncovered is wise. I just don't like how the comment about it being created by a nation state is thrown in there casually as if it were already an accepted fact when it is not.

Agreed!
