    macOS’s “malware resistance” was always due to the fact that nobody bothered to develop malware for it due to its unpopularity relative to Windows. The same holds true for Linux. On the whole, a Windows desktop has much more innate resilience to malware than macOS and Linux.

    If the validator just checks if the public key is the same, then you can chain to that CA. So in effect, what you do is move the "difficult" problem is figuring out a d where Q=dG to a different curve where Q=d'G' but at that curve the problem is easier to solve.

    My best guess regarding CVE-2020-0601 is that you can get the public key (Q) of a trusted CA, figure out a vulnerable curve that contains that point, get the private key (d) at that curve, and sign something. You explicitly specify all parameters and the signature is valid.

    DNS-over-HTTPS will be rolled out by default in Firefox for U.S. users starting at the end of September 2019. Firefox will default to using Cloudflare's 1.1.1.1 at first, but that may change if other resolvers adopt a comparably strong privacy policy.

    Looks like Microsoft has a new Root Program for the Azure Front End. It seems it consists of DigiCert, GlobalSign, and some Chinese CAs I have not heard of and can not find. It also seems there is no contact for details on how to get into this "short-list"
