Phishing assaults elevated almost 40 % within the yr ending August 2024, with a lot of that progress concentrated at a small variety of new generic top-level domains (gTLDs) — corresponding to .store, .high, .xyz — that appeal to scammers with rock-bottom costs and no significant registration necessities, new analysis finds. In the meantime, the nonprofit entity that oversees the area identify business is shifting ahead with plans to introduce a slew of recent gTLDs.

A examine on phishing knowledge launched by Interisle Consulting finds that new gTLDs launched in the previous few years command simply 11 % of the marketplace for new domains, however accounted for roughly 37 % of cybercrime domains reported between September 2023 and August 2024.
Interisle sources knowledge about cybercrime domains from anti-spam organizations, together with the Anti-Phishing Working Group (APWG), the Coalition Towards Unsolicited Business Electronic mail (CAUCE), and the Messaging, Malware, and Cell Anti-Abuse Working Group (M3AAWG).
The examine finds that whereas .com and .web domains made up roughly half of all domains registered prior to now yr (greater than all the different TLDs mixed) they accounted for simply over 40 % of all cybercrime domains. Interisle says an nearly equal share — 37 % — of cybercrime domains have been registered by means of new gTLDs.
Spammers and scammers gravitate towards domains within the new gTLDs as a result of these registrars have a tendency to supply low cost or free registration with little to no account or id verification necessities. For instance, among the many gTLDs with the best cybercrime area scores on this yr’s examine, 9 supplied registration charges for lower than $1, and almost two dozen supplied charges of lower than $2.00. By comparability, the most affordable worth recognized for a .com area was $5.91.
At present, there are round 2,500 registrars approved to promote domains by the Web Company for Assigned Names and Numbers (ICANN), the California nonprofit that oversees the area business.

Extremely, regardless of years of those reviews displaying phishers closely abusing new gTLDs, ICANN is shuffling ahead on a plan to introduce much more of them. ICANN’s proposed subsequent spherical envisions accepting functions for brand new gTLDs in 2026.
John Levine is writer of the ebook “The Web for Dummies” and president of CAUCE. Levine mentioned including extra TLDs and not using a a lot stricter registration coverage will possible additional develop an already plentiful greenfield for cybercriminals.
“The issue is that ICANN can’t make up their thoughts whether or not they’re the impartial nonprofit regulator or simply the area speculator commerce affiliation,” Levine advised KrebsOnSecurity. “However they act much more just like the latter.”
Levine mentioned the overwhelming majority of recent gTLDs have just a few thousand domains — a far cry from the variety of registrations they would wish simply to cowl the up-front prices of working a brand new gTLD (~$180,000-$300,000). New gTLD registrars can shortly appeal to clients by promoting domains cheaply to clients who purchase domains in bulk, however that tends to be a dropping technique.
“Promoting to criminals and spammers seems to be awful enterprise,” Levine mentioned. “You’ll be able to cost no matter you need on the primary yr, however you must cost checklist worth on area renewals. And criminals and spammers by no means renew. So if it sounds just like the economics is mindless it’s as a result of the economics is mindless.”
In nearly all earlier spam reviews, Interisle discovered the highest manufacturers referenced in phishing assaults have been the biggest know-how corporations, together with Apple, Fb, Google and PayPal. However this previous yr, Interisle discovered the U.S. Postal Service was by far the most-phished entity, with greater than 4 instances the variety of phishing domains because the second most-frequent goal (Apple).
A minimum of a few of that enhance is probably going from a prolific cybercriminal utilizing the nickname Chenlun, who has been promoting phishing kits focusing on home postal providers in america and at the least a dozen different nations.
Interisle says an growing variety of phishers are eschewing area registrations altogether, and as an alternative making the most of subdomain suppliers like blogspot.com, pages.dev, and weebly.com. The report notes that cyberattacks hosted at subdomain supplier providers might be powerful to mitigate, as a result of solely the subdomain supplier can disable malicious accounts or take down malicious internet pages.
“Any motion upstream, corresponding to blocking the second-level area, would have an effect throughout the supplier’s complete buyer base,” the report observes.
Interisle tracked greater than 1.18 million situations of subdomains used for phishing prior to now yr (a 114 % enhance), and located greater than half of these have been subdomains at blogspot.com and different providers operated by Google.
“Many of those providers enable the creation of huge numbers of accounts at one time, which is very exploited by criminals,” the report concludes. “Subdomain suppliers ought to restrict the variety of subdomains (person accounts) a buyer can create at one time and droop automated, high-volume automated account sign-ups – particularly utilizing free providers.”
