Once a CA gives out one bad certificate, they are done. If your risk profile includes someone being willing to throw away an entire CA to get to you, then you should worry about it. For 99.999% of people and companies, I don’t imagine that is a reasonable concern.
- est31 3y agoCAs give out bad certificates all the time. Whether they are done depends on the reason. Often people give fradulent information to CAs, which leads to them issuing a certificate. This is usually discovered soon after the fradulent issuance, but for some victims it might still be too late. If the CA proves that it followed due diligence, and this happens rarely enough, they won't be distrusted by browsers.
