Massive blocking of foreign media in China

After Tuesday’s report Leaked Records Reveal Offshore Holdings of China’s Elite by ICIJ, China blocked a number of major newspaper websites. All websites below were blocked after publishing copies of the original report. They're all listed as the publishing partners for “Chinaleaks” stories on ICIJ's website. The Great Firewall rarely blocks non-Chinese websites. Many of them have published the Chinese version of the report which probably explains the unusual development.

The blocks are unusually severe. First of all, while the Great Firewall is capable of blocking individual articles or sections, the above websites are all entirely blocked. For BBC, they only blocked the article, not the entire website. For This is often the standard way of censoring reports. Why such a blanket block?

Update: We have found the reason for such block. Any website listed as the publishing partners for “Chinaleaks” stories by ICIJ is completely blocked. Websites not listed have individual stories related to the incident blocked or not blocked at all. We can infer that the government blocked them more for revengen than for controlling the information. Only a small percentage of Internet users in China read in English, let alone German, Spanish, etc.

Second, English websites are not usually the targets of the censors. For example, the article posted in English by SCMP is not blocked. In the case of reports of Xi Jinping and Wen Jiabao a year ago, only Chinese websites and the original English websites were affected, not other media that reported on the stories.

Perhaps the severity of the block suggests that Chinese leaders are particularly concerned about this report.

Interestingly, few Chinese versions of foreign media are covering the story. There is no mention of it on Reuters Chinese, WSJ Chinese, IBTimes ChineseNanzao. These websites have also all remained unblocked. Only NYT Chinese, which has blocked for a long time, covered the story. This suggests that the strategy of forcing the foreign press to self-censor by threatening with website blocks and visa denials is working.

We at GreatFire.org believe in a free Internet. We have created an unblockable mirror for the report in Chinese and English. Please share with all your friends behind the Great Firewall.

CORRECTION (posted Janaury 23, 2014): FT Chinese has posted a story about the ICIJ report, in English and Chinese.The individual article is blocked.

The French language website for the CBC, Radio Canada, has not been blocked and they have posted an extensive story in French about the ICIJ report.

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,

Floor 1, Building 1,

Software Park, Chinese Academy of Sciences,

4 South 4th Street, Zhongguancun,

Beijing, China, 100190

 

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.

Outlook grim - Chinese authorities attack Microsoft

On January 17, we received reports that Microsoft’s email system, Outlook (which was merged with Hotmail in 2013), was subjected to a man-in-the-middle (MITM) attack in China.

The following screenshot shows what happens when a Chinese user accesses Outlook via an email client (in this case, Ice-dove):

We have tested Outlook to verify the attack and have produced the same results. IMAP and SMTP for Outlook were under a MITM attack. Do note however that the web interfaces (https://outlook.com and https://login.live.com/ ) were not affected. The attack lasted for about a day and has now ceased.

This form of attack is especially devious because the warning messages users receive from their email clients are much less noticeable than the warning messages delivered to modern browsers (see screenshot at the end of this post for comparison).

GFW upgrade fail - visitors to blocked sites redirected to porn

In the past, the Chinese authorities’ DNS poisoning system would direct Chinese internet users who were trying to access Facebook, Twitter and other blocked websites (without the use of a circumvention tool) to a set of fake IP addresses that are blocked in China or are non-existent. After waiting for some time, Chinese internet users would receive a timeout message if they were trying to access a blocked site.

However, with the new DNS poisoning system, in addition to those IP addresses used before, the Chinese authorities are using real IP addresses that actually host websites and are accessible in China. For example, https://support.dnspod.cn/Tools/tools/ shows that if a user tries to access Facebook from China, they might instead land on a random web page, e.g. http://178.62.75.99

Below is a screenshot by a Chinese user when he was trying to access our GreatFire.org website which was blocked in China. He was redirected to a goverment site in Korea. In essense, GFW is sending Chinese users to DDOS the Korea government's website.

One Chinese Internet user reported to us that when he tried to access Facebook in China, he was sent to a Russian website, unrelated to Facebook. Another user tweeted that he was redirected to an German adult site when he tried to access a website for a VPN.

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.

Gmail completely blocked in China

All Google products in China have been severely disrupted since June of this year and Chinese users have not been able to access Gmail via its web interface since the summer. However, email protocols such as IMAP, SMTP and POP3 had been accessible but are not anymore. These protocols are used in the default email app on iPhone, Microsoft Outlook on PC and many more email clients.

On December 26, GFW started to block large numbers of IP addresses used by Gmail. These IP addresses are used by IMAP/SMTP/POP3. Chinese users now have no way of accessing Gmail behind the GFW. Before, they could still send or receive emails via email clients even though Gmail's web interface was not accessible. 

Google's own traffic chart shows a sharp decline of Chinese traffic to Gmail. 

Below is a ping request to the Gmail SMTP server, which is completely inaccessible in China.
