Donuts offers name spinner to show potential attacks
Donuts has launched a tool to show off its TrueName offering, which blocks potential phishing attacks at the domain registry level.
It’s like a regular name spinner, but instead of showing you available domains it shows you visually confusingly similar domains — homographs — that it will block if you register said name in any of Donuts’ portfolio of 2xx (subs, please check) TLDs.
For example, spinning truename.domains returns results such as trʋenɑme.domains (xn--trenme-exc57b.domains) and trᵫname.domains (xn--trname-xk6b.domains), which could be used in phishing attacks.
How many strings get blocked depends largely on what characters are in your name. The letters I and O have a great many visually confusing variants in other non-Latin scripts, and each instance exponentially increases the potential attack vectors.
For example, if I were to register “domainincite” in one of Donuts’ TLDs, Donuts would block 767 homographs at the registry level, but if I were to register “kevinmurphy”, it would only need to block 119.
It only blocks the homographs in the same TLD as the original name. It’s not a replacement for brand protection in other TLDs.
Donuts doesn’t charge anything extra for this service. It’s included in the price of registration and offered as a unique perk for Donuts’ selection of gTLDs.
I gave TrueName a brief post when it launched last year, but I have to say I really like the idea. It’s a rare example of true innovation, rather than simple money-grubbing, that has come from the new gTLD program.
If Verisign were to roll out something similar in .com, it would eliminate a bunch of phishing and cut down on legal fees for big brands chasing phishers and typosquatters through UDRP or the courts.
It was born out of Donuts’ Domain Protected Marks List product, which allows trademark owners to block their brands and homographs across the whole Donuts stable for less money than defensively registering the names individually.
The downside of the spinner tool is of course that, if you’re a bad guy, it simplifies the process of generating samples of homograph Punycode (the ASCII “xn--” string) that can be used in any non-Donuts TLD that supports internationalized domain names.
The tool is limited to 10 domains per spin, however, which limits the potential harm.
