Thanks; I was just about to post that link to this thread.
Certificates don't spread virally, and random browsers don't go looking
for whatever interesting certificates they find. They also don't like
certs that say "*.google.com" when the user is trying to go somewhere else;
that web site would be non-functional unless it was trying to impersonate
a Google domain. Taken all together, this sounds to me like deliberate
mischief by someone. In fact, were it not for the facts that the blog
post says that Google learned of this on December 24 and this thread started
on December 14, I'd wonder if there was a connection -- was this the
incident that made Google reassess its threat model?
Of course, this attack was carried out within the official PKI framework...
