Mapping the Mal Web: Online safety risks are a truly global issue. Yet differences in threats vary significantly by country and other factors, for example:
* A consumer is almost 12 times more likely to encounter a drive-by-download while surfing Russian domains as Columbian ones.
* Registering at a Web site in India results in a 4.3% chance of getting spammy e-mail. Taking the same action with a domain registered in China yields a 7.2% chance.
* 5.2% of Vietnamese Web sites have risky downloads. Just 0.5% of Singaporean sites host such files.
* 2.7 million times every month, casual Web surfers visit risky Dutch Web sites. Even though Hong Kong has approximately the same percentage of risky Web sites, those risky domains receive just 52,000 clicks each month. [...]
Key Findings
4.1% of all sites tested by SiteAdvisor are rated red or yellow. But the incidence of red and yellow sites varies dramatically across top-level domains, ranging from a low of 0.1% for Finland (.fi) to a high of 10.1% for the tiny island of Tokelau (.tk). We find that Tokelauan domains, discussed later, offer some advantages to scammers.
* The most risky large countries are Romania (.ro, 5.6% risky sites) and Russia (.ru, 4.5% risky sites). These country TLDs are also the most likely to host exploit sites.
* .info is the riskiest generic TLD, with 7.5% of its sites rated as risky. .com is the second most risky generic TLD, with 5.5% of sites rated as risky.
* Four of the five least risky country TLDs are Nordic countries - Finland (0.10%), Norway (.no, 0.16%), Sweden (.se, 0.21%) and Iceland (.is, 0.19%). Ireland (.ie, 0.11%) rounds out the top five least risky country TLDs.
* .gov is the only frequently tested TLD for which SiteAdvisor has found no risky sites. .gov is only available to United States government agencies.
* Even though the .com TLD is only the 5th most risky TLD by rank, its huge popularity magnifies its impact on search and browsing risk dramatically. 86.6% of clicks to red and yellow rated sites go to .com sites.
* Even though the Netherlands (.nl), Germany (.de) and the United Kingdom (.uk) are all relatively safe TLDs, ranking 31st, 33rd and 51st most risky, each of their TLDs account for more than 2 million clicks to red and yellow sites every month. Likewise Japan (.jp) is ranked 57th most risky and yet red and yellow rated .jp sites receive an estimated 1.6 million clicks each month.
