Note that 8,827 (66.9%) of the IP addresses originate from Taiwan and Hong Kong, two regions where Chinese is the official language. China, however, accounted for only 18 requests. This is consistent with malicious code injected into China-hosted websites at the border of the Chinese Internet.

To determine which websites have their responses altered by the injection of malicious code, we extracted the domain names of the 25 most frequently seen referrers in our dataset,20 finding that these domains account for 55% of the total requests in the sample.
为了确定哪个网站的响应被注入的恶意代码修改了，我们从数据集合中的25个最频繁出现的引用中提取了域名，发现这些域名占样本里所有请求的55%。
