Google Chrome Bans Chinese SSL Certificate Authorities WoSign and StartCom

As a punishment announced last October, Google will no longer trust SSL/TLS certificate authorities WoSign and its subsidiary StartCom with the launch of Chrome 61 for not maintaining the "high standards expected of CAs." The move came after Google was notified by GitHub's security team on August 17, 2016, that Chinese Certificate Authority WoSign had issued a base certificate for one of GitHub's domains to an unnamed GitHub user without authorization. After this issue had been reported, Google conducted an investigation in public as a collaboration with Mozilla and the security community, which uncovered several other cases of WoSign misissuance of certificates. As a result, the tech giant last year began limiting its trust of certificates backed by WoSign and StartCom to those issued before October 21st, 2016 and has been removing whitelisted hostnames over the course of several Chrome releases since Chrome 56.

Chinese Certificate Authority 'mistakenly' gave out SSL Certs for GitHub Domains

A Chinese certificate authority (CA) appeared to be making a significant security blunder by handing out duplicate SSL certificates for a base domain if someone just has control over its any subdomain. The certificate authority, named WoSign , issued a base certificate for the Github domains to an unnamed GitHub user. But How? First of all, do you know, the traditional Digital Certificate Management System is the weakest link on the Internet today and has already been broken? Billions of Internet users blindly rely on hundreds of Certificate Authorities (CA) around the globe to ensure the confidentiality and integrity of their personal data. But, these CAs have powers to issue valid SSL cert for any domain you own, despite the fact you already have one purchased from another CA. ...and that's the biggest loophole in the CA system. In the latest case as well, WoSign issued a duplicate SSL certificate for GitHub domains without verifying ownership of the base domain.
