The simple solution would be to have independent entities offer trust assertions about CAs and to allow users to consider multiple entities' views in their decision about whether to trust. It's surprising this doesn't exist yet when the attack vector is so clear.

The certificate is for a specific IP address, no? And without DNS pointing google.com to that IP address, it's pretty useless.
Nope, certificates are issued for CNs(Common Name), also known as FQDNs (Fully qualified domain names). Something such as *.google.com, not IP addresses. If they were issued for IP addresses they would have to reissue the certificate every time they spun up a new server. Also it's why if you spin up another server and make DNS point google.com to that server, it would not pass verification since the certificate you w…

#43This is a bad look. I expected the result would be Chrome and Firefox dropping trust for this CA, but they already don't trust this CA. Arguably, Microsoft/Windows trusting a CA that the other big players choose not to trust is an even worse look for Microsoft.
Also being issued on a major US holiday- when many are on PTO- does not help with the look.
Would it be fair during that time if I asked you to hold your PRs, bug tickets and work in general because we're on paid leave?
On-call rotation exists for those reasons. Otherwise, all countries would need to respect all other countries holidays.
In fact, we're not even aware of most US holidays. It is likely to be a coincidence.

These are generally government CAs, so, typically the situation is Microsoft sold the government Windows, and as part of that deal (at least tacitly) agreed to the CA being trusted, and so every system that's trusting these certificates is a Windows PC anyway, running Edge because the whole point was the government will only use Windows and pays Microsoft $$$. Why bake it into everybody else's Windows? If you make sa…
what's the state's interest in having their CA built into windows?
That CA is not used for much else and is basically confined to our state. But it has to be in Windows, otherwise no other software could verify the signatures.
See eIDAS and other similar schemes.

Windows is less popular every year.

The Subject field is not consulted so long as the SAN field is present, and can in theory be any X.500 Distinguished Name, of which Common Name is one possible attribute, which may be any freeform string of a limited length (though it is typically set to the primary domain the cert is issued for, for easy identification).

Unlike web browsers, digital signature use cases should perform revocation checks, so revoking the google.com certificate should solve that.
