- SSLMate/Certspotter: Certificate Transparency Log Monitor

Last Chance to Fix EIDAS (Mozilla)
> 1. Is this proactively monitored for? And how? And by whom?
Yes, security researchers and domain owners use Certificate Transparency Monitors to search for certificates. e.g.:
https://crt.sh/ - allows you to search for certificates for a domain
https://github.com/SSLMate/certspotter/ - open source tool which notifies you when a certificate is issued for one of your domains
https://sslmate.com/certspotter/ - commercial service that does the same, operated by my company
> 2. If a major state-level CA was discovered to have issued a mitm cert, would browser vendors really take the commercial hit of removing or distrusting their root cert?
In 2017, Chrome and Firefox distrusted Symantec, which was at the time the world's largest certificate authority: https://security.googleblog.com/2017/09/chromes-plan-to-dist...
Symantec hadn't even issued MitM certs - they were just grossly incompetent. Distrusting them was very painful, but necessary to upload the integrity of the CA system, and demonstrated conclusively that there is no such thing as a too-big-to-fail CA.

Encrypted traffic interception on Hetzner and Linode targeting Jabber service
Indeed, a CT monitor which sends alerts about legitimate certificates is pretty much useless due to noise. My service, Cert Spotter, provides an API endpoint[1] which you can upload your CSRs to, so you don't get alerted about certificates using the same key as the CSR. The open source version of Cert Spotter can invoke a script[2] when a certificate is discovered, and the script can cross reference against a list of legitimate certs.

Homebrew installed infected software?
as it states on that page it pulls from https://github.com/hlandau/acmetool <- Is the original repo, and if it were infected would be the source of the SCA.
