CNNIC leadership change coincides with blocking of Gmail

On December 26, 2014, in an announcement posted on their website, a new chairperson for CNNIC was directly appointed by the Cyberspace Administration of China. The announcement of this appointment coincided with the complete blocking of Gmail.

Cyberspace Administration of China (中央网信办) is chaired by Lu Wei, “China’s web doorkeeper”. Lu Wei is also the vice chair of the Central Propaganda Department, according to his official resume.


This office is directly responsible for the blocking of Gmail and other websites including Facebook, Twitter and Google.

CNNIC is China’s certification authority and operates the country’s domain name registry. 

What are certificates used for?

Certificates are used primarily to verify the identity of a person or device, authenticate a service, or encrypt files. 

What is a certification authority (CA)?  

Certification authorities are the organizations that issue certificates. They establish and verify the authenticity of public keys that belong to people or other certification authorities, and they verify the identity of a person or organization that asks for a certificate.

Before September 2014, CNNIC was nominally led by the Chinese Academy of Science (中国科学院). This partly explains how CNNIC was able to convince large software vendors to trust them as a certificate authority. But now CNNIC is directly governed by an office that is directly in charge of censorship and GFW. Lu Wei and Cyberspace Administration of China report to Xi Jinping directly.

We have outlined CNNIC's dubious history in a previous blog post. Now that CNNIC is directly under the control of the office that is responsible for Chinese internet censorship controls, we again strongly encourage organizations, including Apple and Microsoft, to revoke CNNIC certificates.

In July 2014, Microsoft revoked their trust in a certificate authority operated by the Indian government. In an advisory posted on Microsoft's website, the company states:

“...improperly issued SSL certificates that could be used in attempts to spoof content, perform phishing attacks, or perform man-in-the-middle attacks.”

As we noted in our post about CNNIC, they have been complicit in or have allowed the man-in-the-middle (MITM) attacks against Apple, Google, Yahoo and Microsoft in October of this year. In 2005, CNNIC produced award-winning malware.

Microsoft and others are likely hesitant to revoke CNNIC certificates given the message that this would send to the Chinese authorities. This kind of action would also likely generate considerable negative press for Lu Wei and his office. But we urge companies like Microsoft to consider what could happen if they do nothing.

The complete block of Gmail was likely related to the appointment of a new chairperson for CNNIC. Through this person, Lu Wei is continuing to build his profile as China’s internet czar and to centralise more of China’s internet administration under his direct control. Lu Wei has not been shy about sharing his thoughts on Facebook’s plans to enter China:

He (Lu Wei) unapologetically defended China’s need for stronger Internet controls at a trade conference in London in June, and at an October news conference in Beijing, he made it plain that an unfettered Facebook could not expect to operate in China.

“I didn’t say Facebook could not enter China, but nor did I say that it could,” he said.

In the future, we can expect that censorship measures will be put in place on a more timely basis and that the authorities will be able to act much faster when controlling information which they deem to be sensitive.

About those 674 apps that Apple censored in China

Apple opened the door on its censorship practices in China - but just a crack.

Is China establishing cyber sovereignty in the United States?

Last week Twitter came under attack from a DDoS attack orchestrated by the Chinese authorities. While such attacks are not uncommon for websites like Twitter, this one proved unusual. While the Chinese authorities use the Great Firewall to block harmful content from reaching its citizens, it now uses DDoS attacks to take down content that appears on websites beyond its borders. For the Chinese authorities, it is not simply good enough to “protect” the interests of Chinese citizens at home - in their view of cyber sovereignty, any content that might harm China’s interests must be removed, regardless of where the website is located.

And so last week the Chinese authorities determined that Twitter was the target. In particular, the authorities targeted the Twitter account for Guo Wengui (, the rebel billionaire who is slowly leaking information about corrupt Chinese government officials via his Twitter account and through his YouTube videos. Guo appeared to ramp up his whistle-blowing efforts last week and the Chinese authorities, in turn, ramped up theirs.

China is the obstacle to Google’s plan to end internet censorship

It’s been three years since Eric Schmidt proclaimed that Google would chart a course to ending online censorship within ten years. Now is a great time to check on Google’s progress, reassess the landscape, benchmark Google’s efforts against others who share the same goal, postulate on the China strategy and offer suggestions on how they might effectively move forward.

What has Google accomplished since November 2013?

The first thing they have accomplished is an entire rebranding of both Google (now Alphabet) and Google Ideas (now Jigsaw). Throughout this blog post, reference is made to both new and old company names.

Google has started to develop two main tools which they believe can help in the fight against censorship. Jigsaw’s DDoS protection service, Project Shield, is effectively preventing censorship-inspired DDoS attacks and recently helped to repel an attack on Brian Krebs’ blog. The service is similar to other anti-DDoS services developed by internet freedom champions and for-profit services like Cloudflare.

Facebook: Please, not like this

Facebook is considering launching a censorship tool that would enable the world’s biggest social network to “enter” the China market. Sadly, nobody will be surprised by anything that Mark Zuckerberg decides to do in order to enter the China market. With such low expectations, Facebook is poised to usurp Apple as China’s favorite foreign intelligence gathering partner. If the company launches in China using this strategy they will also successfully erase any bargaining power that other media organizations may hold with the Chinese authorities.

我们开发速度测试的目的是要真实反映用户的体验。当用户在网站测速时,浏览器在后台会从10个世界上最流行的网站上下载一些资源文件。根据Alexa排名,这些网站分别是Google, Facebook, YouTube, Baidu, Amazon, Yahoo, Wikipedia, QQ, Twitter and Microsoft Live。速度的结果是简单的计算下载文件文件的大小和下载所需的时间。我们同样也会验证下载的文件是否完整。如果文件的内容是错误的或者在40秒内无法完成下载,我们会标记为失败。这个数据被我们用来生成另一个重要指标-稳定性。


我们的第二个指标 - 稳定性 - 是其他的服务通常不会测试的。一个健康的互联网连接应该达到100%的稳定性,除非有人在测试中把网线拔了。但是在中国使用翻墙工具却不是这样。任何时候连接都有可能变得不稳定或十分缓慢。根据请求的大小,最终的地点和代理的方式,一些请求有可能会失败。比较服务的稳定性要比比较速度更加重要。
