How would they sneak the private keys from e.g. Digicert/Geotrust/ISRG?

  And there would be no point in doing so anyway. Chrome, etc., require that certificates which descend from publicly trusted roots have their certificates published in certificate transparency logs. Someone would quickly notice bogus certs being issued and the associated root would get blacklisted.

  This is why certificate transparency is required now - it means that we no longer need to trust the CAs to tell us when they’ve issued an unconstrained intermediate or cross signed a root. Previously it was essentially luck that led to CA malfeasance being detected. Especially in the post-finally-ending Symantec world the CAs understand that issuing any such cert is likely to very quickly end their business in most other countries. I feel the real problem kz is going to have is that they have now demonstrated that they will abuse having a root cert, so there is no way any root stores will let them in in future. I imagine they’d even have difficulty getting any of the other roots to issue certs for them (managed sub-ca I think? I forget terminology)
