One of the largest Chinese root certificate authority WoSign issued many
fake certificates due to an vulnerability. WoSign's free certificate
service allowed its users to get a certificate for the base domain if they
were able to prove control of a subdomain. This means that if you can
control a subdomain of a major website, say percy.github.io, you're able to
obtain a certificate by WoSign for github.io, taking control over the
entire domain.
