That is to say: we asked Comodo to issue us another certificate from the same root the bogus ones were issued from, but for a domain Kai controls. We then added that cert's serial number to the blacklist (which is why it's 8 certificates long rather than 7). This means we don't need to set up a server using one of the compromised certs (which is impossible, as we don't have the private keys) in order to test the blocking. Instead, we can use https://kuix.de:9449/ , which is using the cert Kai obtained and we have now blacklisted.
