These three new gTLDs have approximately 318,000 registrations between them out of a total of 26.9 million, but have the highest concentrations of malicious domains according to a recent study.
The report examines four domain characteristics: gTLDs, Whois privacy provider, free email provider and IP geolocation. It found that 60% of the domain names registered in .science had been blacklisted.
"We expect a lot of churn for the foreseeable future as the Top Level Domain space continues to expand, but that should not stop investigators from paying attention to the top ten from this year," said Tim Helming, Director of Product Management at DomainTools. Helming clarified that these TLDs are not inherently malicious, as single registrants can be responsible for the vast majority of nefarious domains.
