The .com domain is still the runaway leader TLD for phishing, with new gTLDs still being used for a tiny minority of attacks, according to new research.
.com domains accounted for 51% of all phishing in 2016, despite only having 48% of the domains in the “general population”, according to the 2017 Phishing Trends & Intelligence Report
from security outfit PhishLabs.
But new gTLDs accounted for just 2% of attacks, despite separate research showing they have about 8% of the market.
New gTLDs saw a 1,000% increase in attacks on 2015, the report states.
The statistics are based on PhishLabs’ analysis of nearly one million phishing sites discovered over the course of the year and include domains that have been compromised, rather than registered, by attackers.
The company said:
Although the .COM top-level domain (TLD) was associated with more than half of all phishing sites in 2016, new generic TLDs are becoming a more popular option for phishing because they are low cost and can be used to create convincing phishing domains.
There are a few reasons new gTLDs are gaining traction in the phishing ecosystem. For one, some new gTLDs are incredibly cheap to register and may be an inexpensive option for phishers who want to have more control over their infrastructure than they would with a compromised website. Secondly, phishers can use some of the newly developed gTLDs to create websites that appear to be more legitimate to potential victims.
Indeed, the cheapest new gTLDs are among the worst for phishing — .top, .xyz, .online, .club, .website, .link, .space, .site, .win and .support — according to the report.
But the numbers show that new gTLDs are significantly under-represented in phishing attacks.
According to separate research from CENTR, there were 309.4 million domains in existence at the end of 2016, of which about 25 million (8%) were new gTLDs.
Yet PhishLabs reports that new gTLD domains were used for only about 2% of attacks.
CENTR statistics have .com with a 40% share of the global domain market, with PhishLabs saying that .com is used in 51% of attacks.
The difference in the market share statistics between the two sets of research is likely due to the fact that CENTR excludes .tk from its numbers.
Again, because PhishLabs counts hacked sites — in fact it says the “vast majority” were hacked — we should probably exercise caution before attributing blame to registries.
But PhishLabs said in its report:
When we see a TLD that is over-represented among phishing sites compared to the general population, it may be an indication that it is more apt to being used by phishers to maliciously register domains for the purposes of hosting phishing content. Some TLDs that met these criteria in 2016 included .COM, .BR, .CL, .TK, .CF, .ML, and .VE.
By far the worst ccTLD for phishing was Brazil’s .br, with 6% of the total, according to the report.
Also notable were .uk, .ru, .au, .pl, and .in, each with about 2% of the total, PhishLabs said.
