McAfee Picks the Most Dangerous TLDs
CWRUisTakingMyMoney writes "Companies that assign addresses for Web sites appear to be cutting corners on security more when they assign names in certain domains than in others, according to a report to be released Wednesday by antivirus software vendor McAfee Inc. McAfee found the most dangerous domains to navigate to are .hk, .cn, and .info. Of all .hk sites McAfee tested, it flagged 19.2 percent as dangerous or potentially dangerous to visitors; it flagged 11.8 percent of .cn sites and 11.7 percent of .info sites that way. A little more than 5 percent of the sites under the .com domain — the world's most popular — were identified as dangerous."
The thing is far from foolproof. When I was bored one day I decided to start clicking on just about all the Google Adwords adverts I could find. Most of them were for those scam sites, you know the kind "click here to buy Firefox, Buy supsciption to Bittorent now!" Over half the sites were green according to Site Advisor. Really I'm sure that their numbers here at least give an idea as the how "dangrous" these TDLs are, put really they are liekly far off from the truth.
He's right. If you pick a single site to interact with, the total number of sites that share that domain doesn't matter. His analogy is spot on.
In effect, he defined Bayes' rule for you.
