Going into the weekend, I'd read some technical commentary on
behind-the-scenes skullduggery. Unfortunately, I couldn't clearly
remember where: It might have been on the Debian bug, or some of the
Mozilla discussion. Anyway, I remember reading a very interesting
analysis that said that DigiNotar had _immediately_, when the scandal
broke, started moving hundreds of its cert attestations over to a
different, related certificate authority (Staat der Nerderlanden) that
they were operating for the benefit of the Dutch government. They were
able to do this sleight of hand because of an early request from the
Dutch government that the CA chain covering its certs not be pulled from
browsers -- thus giving DigiNotar a place to stash their signatures and
sidestep the Net's vote of no confidence in their operations.
The other shoe has now dropped on _that_ matter: The Dutch goverment
did an audit on the signings DigiNotar had done of its SSL certs, and
have now _rescinded_ their initial assessment that their certs were OK,
having been handled independently of DigiNotar's other processes. The
government of Netherlands now says, paraphrased, 'You know, sorry. We
were wrong. They're bozos, and they exposed _our_ certs to compromise,
too. Go ahead and remove trust of the rest of their signatures, too.'
There are a _lot_ of fraudulent certs, it turns out.

Anonymous is not alone in pushing the extremely bad idea of merging SSL
cert validation into DNSSEC. But we've already covered that.
