Wouldn’t it be convenient if all the spam and malware sites were all grouped together under one top-level domain — .evil, say — so that they would be easy to avoid? According to a new study from Blue Coat, there are in fact ten such top-level domains, where 95 percent or more of sites pose a potential threat to visitors.
The worst offenders were the .zip and the .review top-level domains, with 100 percent of all sites rated as “shady,” according to the report.
The report is based on an analysis of tens of millions of websites visited by Blue Coat’s 75 million global users. In order to protect its customers, Blue Coat has a database where it ranks websites on whether they have legitimate content, or malware, spam, scams, phishing attacks or other suspicious behaviors.
