Hong Kong's ".hk" is now the world's most dangerous domain for surfing and searching, according to a report released today (4 June) by security company McAfee.
However the survey's methodology and findings have been challenged by a Hong Kong-based expert.
The Hong Kong Special Administrative Region (SAR) moved from number 28 in 2007 to the top of the company's "Mapping the Mal Web" survey, edging out its northern neighbour China's ".cn," which came second. Finland's ".fi" was the safest, followed by Japan's ".jp."
Just over 19 percent of ".hk" contain malware, viruses, have a high rate of spam or feature aggressive pop-up ads, McAfee said, as determined by a survey of 74 top-level domains using its SiteAdvisor software.
Over 11 percent of ".cn" sites for China were similarly found to be dangerous. Comparatively, only 0.05 percent ".fi" sites were found to be hazardous.
However, one Hong Kong-based security analyst said the survey did not demonstrate any real risk as emanating from the area.
"McAfee are only looking at the top-level domain bit, they are not looking at the location of the server," said Richard Stagg, director and managing consultant at Handshake Networking. "They're not paying attention to where sites are actually hosted."
The report is also not specific on the degree of danger from the sites using the ".hk" domain, Stagg said, as McAfee puts risks such as malware and annoyances like pop-up ads together.
Malware purveyors and spammers choose their top-level domain registrations based in part on where it is difficult to get a domain name shut down, Stagg said. There are "huge, huge numbers of organised crime Web sites and porn Web sites are registered with .cn domains, but most of them are not hosted in China," he said.
Purveyors of malware and spam choose top-level domains in part based on how difficult it is to shut those domains down. For example, the US Federal Bureau of Investigation can ask Network Solutions to close a .com domain, hosted in the US, within days, Stagg said, whereas it would have no jurisdiction with foreign domain registrars.
