"When it comes to safety, it turns out that the Web is no different than the physical world," said Mark Maxwell, senior product manager of McAfee Consumer and Small Business. "There are safe neighborhoods and safe Web domains, and then there are places no one should ever visit."
Among the key findings of the study are:
- Some Web activities, like registering at a site or downloading a file, are significantly more risky when done at certain domains. For example, giving an e-mail address to a random .info domain results in a stunning 73.2 percent chance of receiving spam e-mail.
- The most risky large country domains are Romania (.ro, 5.6 percent risky sites) and Russia (.ru, 4.5 percent risky sites). These country domains are also the most likely to host exploit or "drive-by-download" sites.
- .info is the riskiest generic domain, with 7.5 percent of its sites rated as risky. .com is the second most risky generic domain, with 5.5 percent of sites rated as risky.
- Three of the five least risky country domains are Nordic countries -- Finland (0.10 percent), Norway (.no, 0.16 percent) and Sweden (.se, 0.21 percent). Iceland (.is, 0.19 percent) and Ireland (.ie, 0.11 percent) round out the top five least risky country domains.
- .gov is the only frequently tested domain for which McAfee has found no risky sites. .gov is only available to United States government agencies.
- Even though the .com domain is only the 5th most risky domain by rank, its huge popularity magnifies its impact on search and browsing risk dramatically.
- Even though the Netherlands (.nl), Germany (.de) and the United Kingdom (.uk) are all relatively safe country domains, ranking 31st, 33rd and 51st most risky respectively, each of their country domains account for more than 2 million clicks to risky sites every month. Likewise Japan (.jp) is ranked 57th most risky and yet risky rated .jp sites receive an estimated 1.6 million clicks each month.
"For administrators of top-level domains, this study should serve as a wake-up call. Clearly, some countries are getting it right. And the more risky top level domains now have the role models they need to improve," added Maxwell. "For consumers, this study is a stark reminder that they need help navigating the Web safely."
