The CNNIC changes started to be applied on December 14th. ...

Oftentimes hacktivism campaigns are fueled by ego-driven script kiddies who use publicly available exploits, but for now we’ll have to wait and see if Twitter decides to publicly announce the details surrounding the attack. The defacement has been removed and Twitter is back up and running as of 11:20 PM PST. ...
