China’s Dangerous Domains
A report by antivirus software firm McAfee looked into the security risks associated with
top-level Internet domains (such as .com, .gov and .uk) and found that the two riskiest
are .hk and .cn, for Hong Kong and China, respectively.
The study used McAfee’s proprietary software to examine 9.9 million Web sites under the
265 country and generic (non-country-specific) domains for signs of “malware” (such as
spyware, viruses, Trojans, spam and excessive pop-up ads) or links to other suspicious Web
sites. This year’s list ranked the 74 most heavily-trafficked top-level domains based on
the frequency of potentially dangerous Web sites (containing malware or suspicious links)
in each domain.
McAfee’s results noted that 19.2% of all the .hk sites it had tested were flagged
as “dangerous or potentially dangerous to visitors.” In China’s .cn domain, 11.8% of the
sites tested were flagged. The third-ranking domain was the generic .info, with 11.7% of
its sites identified as risky. By comparison, about 5% of sites in the popular .com domain
presented security risks, according to McAfee.
The Chinese domains weren’t always so dangerous–according to last year’s report, only
1.2% of .hk sites and 3.7% of .cn sites were flagged. One McAfee researcher mentioned two
factors contributing to the increases: improved data collection and apparent security
lapses in how some domain registrar companies work. Other likely causes: Hong
Kong’s “user-friendly” domain registration system (which encourages the registration of
multiple domain names at once) and China’s low registration costs (about 15 cents
wholesale per domain name), the report says. But McAfee also notes that since individual
domain names may be owned by persons from anywhere in the world, their data “should not be
used to infer riskiness of nationality.”
中国的危险域名
反病毒软件公司McAfee调查有关互联网顶级域名（如：.com,.gov 和 .uk）安全风险的报告发现，
最危险的是.hk域和.cn域，分别代表香港和中国。
这次研究采用的的McAfee专有的软件检查了990万个分布在265个国家和类别（无政府指定）域名下的
网站是否有“恶意软件”（如间谍软件，病毒，特洛伊木马，垃圾邮件或过度的弹出广告。）或链接到其它的
可疑网站。今年的清单对74个访问量最大的顶级域名进行排序，标准是每个域中可能有危险站点（含有恶
意软件或可疑链接）的频率。
McAfee是结果显示19.2%的测试过的所有.hk域的站点被标记为“对访问者有危险或潜在危险”。在中
国的.cn域下，11.8%的被测试站点被标记。排名第三的域是类别域名.info，它当中有11.7%的网站被认定
是危险的。相比这下，按照McAfee的结果，大众的.com域下只有5%的网站呈现出有危险。
中国人的域名并不总是这样危险。按照去年的报告，只有1.2%的.hk网站和3.7%的.cn网站被标记过。
一位McAfee研究员提到增长有两个因素：改良的数据收集和一些域名申请者的安全意识缺失。报告中提
到，其它可能的原因还有：香港的“面向用户”的域名申请机制（鼓励一次申请多个域名）和中国的低廉
的域名费用（批发价每个域名只有约15美分）。但是McAfee也指出既然个人域名可能是来自世界各地的个
人拥有，他们的研究数据“不能被用来引伸到国家的危险性”。
译者注：不管怎么说,中国有这么多的网民,网络发展速度又如此之快，为了我们的互联网良性的发展，还真应该注意我们上网的安全性及网站建设的安全隐患。
