Sina Weibo Enacts New "7 Day Delay" Function for Sensitive Terms Following 18th Party Congress

On November 10, 2012, Reuters published a report entitled "China Party Chief Stresses Reform, Censors Relax Grasp on Internet." An excerpt:

China's largest microblog service unblocked searches for the names of many top political leaders in a possible sign of looser controls a month after new senior officials were named to head the ruling party. 
Searches on the popular Twitter-like Sina Weibo microblog for party chief Xi Jinping, Vice Premier Li Keqiang and other leaders - terms that have long been barred under strict censorship rules - revealed detailed lists of news reports and user comments.

What's actually happened is that Sina Weibo is now imposing a seven day delay on search results for these names, as well as other "sensitive terms" (such as the name of lawyer Xu Zhiyong (许志永)).  Sina Weibo does not notify users when it does this. Read on for more details and examples. The Standing Committee of Political Bureau of the 17th Central Committee of the Chinese Communist Party ("PBSC") comprised the following nine members: Hu Jintao (胡锦涛), Wu Bangguo (吴邦国), Wen Jiabao (温家宝),  Jia Qinglin (贾庆林), Li Changchun (李长春), Xi Jinping (习近平), Li Keqiang (李克强), He Guoqiang (贺国强), Zhou Yongkang (周永康). It is worth noting that Sina Weibo did not always censor searches for the names of all members of the PBSC. For example, this screenshot, taken in February 2012, shows that a search on Sina Weibo for "Xi Jinping" returned hundreds of thousands of results, including posts made just minutes before.

These screenshots were taken on October 27, 2012, and show that by then searches on Sina Weibo for the names of all of the members of the Political Bureau 17th CPC Central Committee always returned the same result - a censorship notice informing the user that "In accordance with relevant laws,  regulations, and policies, search results for 'XXX' have not been displayed." (根据相关法律法规和政策,“XXX”搜索结果未予显示。).

As noted previously on this blog, during the 18th Party Congress (November 8 - 14), Sina Weibo began tweaking its censorship mechanisms, at first eliminating the censorship notice in favor of saying it could find no results. Then it restored the censorship notice in some cases, while in other cases it appeared to show complete search results, but attempting to view more than one page of results would eventually result in a censorship notice. See - http://blog.feichangdao.com/2012/11/in-week-before-party-congress-sina.html Sina also adopted implicit censorship as mentioned in our blog post new censorship on weibo. At around noon on November 15, 2012, Xinhua announced the "List of members of Standing Committee of Political Bureau of 18th CPC Central Committee": Xi Jinping (习近平), Li Keqiang (李克强), Zhang Dejiang (张德江), Yu Zhengsheng (俞正声), Liu Yunshan (刘云山), Wang Qishan (王岐山), and Zhang Gaoli (张高丽). The screenshots below show that, two weeks after the announcement of the new Politburo, Sina Weibo administrators had yet to settle on a consistent approach to censoring information about the Communist Party's new leaders. At first glance, it initially appeared that Sina administrators had decided to not censor searches at all. For example, in the left-hand screenshots below, searches for "Xi Jinping" and "Li Keqiang" apparently returned thousands of results and there is no censorship notice anywhere on the page. A closer look reveals, however, that all of the "Hot Posts" were several days old, and the posts following the "Hot Posts" were actually delayed by almost exactly 48 hours. The right-hand screenshots show that Sina Weibo administrators continued to gradually increase the amount of censorship following the initial relaxation. By November 27, search for "Xi Jinping" was once again returning no results, only a censorship notice, and a search for "Li Keqiang" was returning no results from the previous 48 hours - the most recent result was three days old, and there was only one result from that day.

One month after the announcement of the new members of the Politburo Standing Committee, Sina Weibo appears to have settled on a "new normal" - it will impose a one week delay for search results for all PBSC member's names in Chinese, except for "Hot Posts". The screenshots below show that the most recent results for searches for "Xi Jinping" on December 13 and 14 are from December 6 and 7, respectively.

Sina Weibo does not display a censorship notice for these search results. On December 14, 2012, Sina Weibo was showing results but imposing the delay for searches for the names of all members of the Politburo Standing Committee, as well as Hu Jintao and Jiang Zemin. It was, however, completely censoring searches for "Wen Jiabao."

At the bottom of each search result page, Sina Weibo informs users "In order to provide more varied search results, we have excluded some posts that are relatively similar, you can click here to see all results." (为了提供多样性结果,我们省略了部分相似微博,您可以点击查看全部搜索结果) For uncensored results clicking on this link will take users to an up-to-the-second stream of posts. In the case of the names of Politburo Standing Committee members, however, the user is told "Apologies, unable to find results relating to 'XXX'" (抱歉,未找到“习近平”相关结果。). These screenshots, which show what happens when the link was clicked after a search for "Xi Jinping," indicate that sometimes it takes a few minutes for Sina Weibo to remove search results.

In the left-hand screenshot above, Sina Weibo returns a single search result, along with a censorship notice. The right-hand screenshot, taken a few hours later, shows no results and no censorship notice, just a notice saying no results could be found. Sina Weibo also continued to engage in selective censorship for queries related to China's leadership. These screenshots, taken on November 13, show that searches for "XJP" and "Xi Jinping" in Pinyin returned no results, just a censorship notice.

As another example, these screenshots show that, while Sina Weibo was returning delayed results for "Peng Liyuan" (彭丽媛 - Xi Jinping's wife) in Chinese characters, searches for "Peng Liyuan" in Pinyin returned no results, just a censorship notice.

Finally, these screenshots show that Sina Weibo completely censored searches for "Xi Mingze" (习明泽 - Xi Jinping's daughter) in both Chinese characters and Pinyin.

 

The new rule is not only being applied to leaders and their families. These screenshots show that, whereas a search for "Xu Zhiyong" on November 27 returned results from as recently as November 25, the same search on December 18 did not return any results from the preceding seven days (with the exception of "hot posts").

CNNIC censored Google and Mozilla’s posts about CNNIC CA

This week, Google found unauthorized digital certificates for several Google domains, the root CA of which is CNNIC. Google and Mozilla both publicly disclosed this security incident and published blog posts(Google, Mozilla). However, Chinese translations of Google’s and Mozilla's blog posts were censored on the Chinese Internet.

  • William Long is a prominent Chinese blogger on IT and tech. He translated Google’s security post without adding any personal opinions. The Chinese blogpost ranked #1 when searching CNNIC MITM in Chinese on Google and Baidu. He tweeted that he received a phone call from propaganda department demanding the post to be removed immediately. The post http://www.williamlong.info/archives/4183.html was deleted. Google cache is still available.

Evidence shows CNNIC and CAC behind MITM attacks

Since 2013, we have repeatedly called on major software vendors to revoke CNNIC-issued certificates. Most notably, we raised this issue when we reported on the Cyberspace Administration of China’s (CAC) man-in-the-middle (MITM) attacks on Google, Microsoft’s Outlook, Apple, Yahoo and Github. Mainstream media have reported about these security vulnerabilities before and on March 24, Ars Technica reported on Google’s announcement that they have definitive evidence that CNNIC (China Internet Network Information Center) was behind a new MITM attack on Google.

From our October, 2014 blog post:

We are under attack

We are under attack and we need help.

Likely in response to a recent story in the Wall Street Journal (WSJ), we’ve experienced our first ever distributed denial of service (DDoS) attack. This tactic is used to bring down web pages by flooding them with lots of requests - at the time of writing they number 2.6 billion requests per hour. Websites are not equipped to handle that kind of volume so they usually “break” and go offline.

This kind of attack is aggressive and is an exhibition of censorship by brute force. Attackers resort to tactics like this when they are left with no other options.

We are not equipped to handle a DDoS attack of this magnitude and we need help. Some background:

  • The attack started on March 17 and we are receiving up to 2.6 billion requests per hour which is about 2500 times more than normal levels.

Collateral Freedom and the not-so-Great Firewall

Recognizing that the authorities have been hesitant to crackdown on our method of circumvention, we have accelerated our expansion of the development of collateral freedom, in three key areas.

An Open Letter to Lu Wei and the Cyberspace Administration of China

January 26, 2015

Beijing, China

 

Mr. Lu Wei

Director of the Cyberspace Administration of the People’s Republic of China 中央网络安全和信息化领导小组办公室主任

Director of the State Internet Information Office 国家互联网信息办公室主任

Deputy Director of the Central Propaganda Department of the Chinese Communist Party 中共中央宣传部副部长

Cyberspace Administration of China,

Dear Mr. Lu,

On January 22, 2015, the Cyberspace Administration of China (CAC), which is under your direct control, wrote a response to a story we published about an MITM attack on Microsoft. In the post, your colleague, Jiang Jun, labelled our accusations as "groundless" and  "unsupported speculation, a pure slanderous act by overseas anti-China forces".

We at GreatFire.org take great offense to these comments and we will refute them in this letter.
