Google.com 在中国被封锁

今天, 2012年11月9日, http://www.google.com http://www.google.com.hk 在中国被封锁. 这是从去年2月我们开始监测中国审查以来第一次看到这种情况。以下是我们知道的信息:

  1. 子域名 http://www.google.com, http://mail.google.com, http://google-analytics.com, http://docs.google.com, http://drive.google.com, http://maps.google.com, http://play.google.com 等在中国被DNS污染. 若用户在中国进行DNS查询,用户不会得到真实的服务器IP地址,而得到一个伪造的地址 59.24.3.173. 这个IP地址在韩国,没有任何网站和这个地址有关联.
  2. 这意味着Google的任何网站, 包括谷歌搜索, 在中国的无法被使用, 除非你使用VPN或者其他翻墙工具。
  3. 使用境外的DNS服务器也没用帮助. 在8.8.8.8 DNS查询 www.google.com 也会被中国防火墙污染。
  4. 到目前为止,你仍然可以使用其他国家的谷歌搜索,比如 http://www.google.co.uk.

你可以在这里浏览Google站点的封锁情况: https://zh.greatfire.org/search/google-sites. 你可以选择任何一个网站,并且对其进行实时测试。

影响用户数量史无前例

Facebook, Twitter and YouTube 在中国用户数量还不多时就被中国封锁. 我们认为因为Gmail已经在中国有大量用户,所以中国政府不敢对其进行封锁.对Google进行全面封锁是更进一步了. 虽然谷歌搜索只是中国第二大搜索引擎 (百度第一) ,但中国网民有5亿,谷歌仍然有上百万活跃用户. 根据 Alexa, 谷歌是中国第五大网站. 一个网站被封锁从来没有影响这么多用户. 如果谷歌持续被封锁, 许多中国用户会注意到中国互联网审查的严厉程度. 网民会对此封锁作出如何反应? 会有抗议么? 访问 FreeWeibo来关注中国网民对此事件的反应.

暂时还是永久?

中国共产党正在举行中国共产党第十八次全国代表大会,在大会上党和国家的新一届领导人会被正式选举产生. Google在这期间被封锁不是偶然. 重要的问题是对Google的封锁会在大会闭幕后结束么?我们会全力监测事件动态

别忘了.. Analytics(分析)

 http://www.google-analytics.comhttps://www.google-analytics.com 被封锁不仅代表了你不能访问Google分析的后台,这还表示来自中国的访问者不再被Google分析追踪. 使用Google分析来追踪用户的网站会看到0个用户正在访问你的网站, 无论此网站在中国是否被封锁.

如何应对?

许多VPN和翻墙软件在这些天工作异常活根本不工作. 免费的iPhone应用 OpenDoor 还能使用, 虽然它也偶尔不能访问. 另一个访问Google的访问是访问其他地区的Google,比如 http://www.google.co.uk https://www.google.co.uk 或者 http://www.google.ca https://www.google.ca. 这些域名在未来当然也可能被封锁。

你也可以使用IP地址来直接访问Google. 它们至今未被封锁. 以下是部分IP地址:

Apple blocked CNNIC CA months after MITM attacks

In March of this year, Google found unauthorized digital certificates for several Google domains. The root certificate authority for these domains was the China Internet Network Information Center (CNNIC). CNNIC was controlled by the Chinese government through the Ministry of Industry and Information Technology and is now under the management of the Cyberspace Administration of China (CAC). CNNIC was recognized by all major browsers as a trusted Certificate Authority. If CNNIC signs a fake certificate used in a man-in-the-middle attack, no browser will warn of any unusual activity unless the certificate is pinned.

Malicious Xcode could spread via download manager Xunlei

What’s at stake?

We reported last week that popular Chinese iOS apps were compromised in an unprecedented malware attack. We discovered that the source of the infection was compromised copies of Xcode hosted on Baidu Pan. Apple has published an article urging developers to download Xcode directly from the Mac App Store, or from the Apple Developer website and validate signatures. We’ve now discovered that even if a developer uses a download link seemingly from Apple, he might still be possible to obtain a compromised copy of Xcode.

Please note that we do not have evidence that such attacks has happened. But it is an easy attack that anyone can implement.

How does it work?

This compromise happened because of Xunlei. Xunlei is the most popular download manager in China. Much of its popularity is due to the fact they can accelerate download speeds by pulling resources from other Xunlei users as well as cached copies on the Xunlei server. All of this, however, is invisible to users. Users can simply enter a regular http download address into Xunlei  download manager and the download will start. Chinese developers were using direct download addresses such as http://adcdownload.apple.com/Developer_Tools/Xcode_7/Xcode_7.dmg to download Xcode.

my biggest beef is that translate.google.com was also down for quite significant amount of time. Now, since I was a mere mortal without sophisticated network monitoring algorithms at hand, trying to do some work, i couldn't tell how long it was out for. But i swear that it was down for quite some time. Which was pissing me off -- i mean, translate.google.com. Are you serious???

I believe you're right. Since China poisoned "*.google.com" which would also match translate.google.com subdomain.

Thanks for your workarounds. However, none work at this time, November 12, at 20:42
