ArsTechnica.com reported that Google wants to stop using of WHOIS for TLS domain verifications.

From the article:

Certificate authorities and browser makers are planning to end the use of WHOIS data verifying domain ownership following a report that demonstrated how threat actors could abuse the process to obtain fraudulently issued TLS certificates.

TLS certificates are the cryptographic credentials that underpin HTTPS connections, a critical component of online communications verifying that a server belongs to a trusted entity and encrypts all traffic passing between it and an end user. These credentials are issued by any one of hundreds of CAs (certificate authorities) to domain owners. The rules for how certificates are issued and the process for verifying the rightful owner of a domain are left to the CA/Browser Forum. One “base requirement rule” allows CAs to send an email to an address listed in the WHOIS record for the domain being applied for. When the receiver clicks an enclosed link, the certificate is automatically approved.
