LWN.net Weekly Edition for June 13, 2013
A report from pgCon 2013
Little things that matter in language design
Fraudulent *.google.com certificate issued
Posted Aug 30, 2011 2:40 UTC (Tue) by cesarb (subscriber, #6266)
If I understand correctly the comments there (in particular https://bugzilla.mozilla.org/show_bug.cgi?id=682956#c10), it is more than just removing: it is blacklisting _by name_.
We probably will know how bad it was only after the true bug report is opened up.

blocking by fingerprint blocks one particular CA cert, blocking by name blocks every CA cert with that name, effectively passing a death sentence on that CA (at least under that name, and if the same people submit a new CA to be accepted by the browsers, it's unlikely to be accepted)

How would that work?

Building up the paper trail that a CA needs to be accepted by the browsers does require effort and time but you are right in that I have not worked close enough to the CA/browser relationship to know exactly what is required to register with MS, Mozilla, Apple, Opera, Oracle, Google, RIM, and other vendors.

Things like Linkage Analysis, where they figure out which companies own which other companies, and trace down who actually owns a company.
It's human legwork to maintain their databases. Thus they get to charge money for queries against them.
So, I certainly hope that the major CAs are doing at least a paid check with one of the merchant houses before issueing EV certs, and anyone bundling together a group of CAs for others to trust should either be saying "don't trust us, this is just what we find convenient" (amateur, but sometimes appropriate) or should be doing the same due diligence.

In this case though attackers are believed to have compromised the infrastructure and had enough access that they could issue whatever they liked without going through the audit and security controls. The technical measures which could prevent this are difficult, cumbersome, expensive and not foolproof. At some point you have to be able to accept a CSR from a customer and expose it to the HSA and receive a result. If you can get anywhere in that path you can send your own CSRs and have whatever you want signed.

current patches to Mozilla products will blacklist all DigiNotar-issued
certificates based on "CN=DigiNotar " in the certificate issuer. Users
will be able to add a certificate override for DigiNotar-issued
certificates that have a notBefore date prior to July 1, 2011. Users
will not be able to add a certificate override for any DigiNotar-issued
certificates with a notBefore date after July 1, 2011, which would
include the *.google.com certificate. "

Worse than I thought

It seems it is even worse than I thought. Take a look at http://www.f-secure.com/weblog/archives/00002228.html :
> "If you keep digging deeper, you'll find that although these web defacements are still live right now, they are not new. Much worse: they were done years ago. [...] In fact, these hacks are so old, it's unlikely they are connected to the current problem."
