ICANN threatens to seize gTLD after Whois downtime
Are we about to see our next gTLD registry implosion?
ICANN has whacked the company behind .gdn with a breach notice and a threat that it may seize the TLD, after its Whois systems allegedly suffered days of downtime.
According to ICANN, .gdn exceeded its weekly and monthly downtime limits in late March and early April, in both months triggering the threshold whereby ICANN is allowed to transition the TLD to an Emergency Back-End Registry Operator.
gTLD registries are allowed to have 864 minutes (about 14 hours) of unplanned Whois downtime per month. Downtime exceeding 24 hours per week is enough to trigger ICANN’s EBERO powers.
It appears to be the third time .gdn’s Whois has gone on the blink for longer than the permitted period — ICANN says it happened in April 2018 and August 2019 too. Those incidents were not publicized.
It seems the Russian registry, Joint Stock Company “Navigation-information systems”, managed to fix the problem on April 2, and ICANN is not invoking the EBERO transition, something it has done just a couple times before, just yet.
But it does want NIS to present it with a plan showing how it intends to avoid another spell of excessive downtime in future. It has until May 8, or ICANN may escalate.
.gdn is by most measures a bullshit TLD.
While it was originally intended to address some kind of satellite navigation niche, it eventually launched as a pure generic with the backronym “Global Domain Name” in 2016.
It managed to rack up over 300,000 registrations in the space of a year, almost all via disgraced and now-defunct registrar AlpNames, and was highlighted by SpamHaus as being one of the most spam-friendly of the new gTLDs.
After AlpNames went out of business two years ago, ICANN transferred some 350,000 .gdn names to CentralNic-owned registrar Key-Systems.
Today, Key-Systems has fewer than 300 .gdn domains. The TLD’s zone file dropped by about 290,000 domains in a single day last December.
.gdn had fewer than 11,000 domains under management at the end of 2020, 90% of which were registered through a Dubai-based registrar called Intracom Middle East FZE.
Intracom pretty much only sells .gdn domains, suggesting an affiliation with the registry.
Web searches for live sites using .gdn return not much more than what looks like porn spam.
A busted Whois looks like the least of its problems, to be honest.
As it releases free download, DomainTools says 68,000 dangerous coronavirus domains have been registered
More than 68,000 coronavirus-related domain names have been registered so far in 2020, according to data released by DomainTools today.
The domain intelligence services company has started publishing a list of these domains, updated daily, for free on its web site. You have to submit your email address to get it.
The download comprises a CSV file with three columns: domain, reg date, and Domain Risk Score.
This final field is based on DomainTools’ in-house algorithms that estimate how likely domains are likely to be used in nefarious activities, based on criteria including the domain’s connection to other, known-bad domains.
Only domains with a score of 70 or above out of 100 — indicating they will likely be used for activities such as phishing, malware or spam — will be included on the list, the company said.
The list will be updated daily at 0000 UTC.

AlpNames died months ago. Why is it still the “most-abused” registrar?
Despite going out of business, being terminated by ICANN, and losing all its domains several months ago, defunct AlpNames is still being listed as the world’s most-abused registrar by a leading spam-fighting organization.
SpamHaus currently ranks the Gibraltar-based company as #1 on its list of the “The 10 Most Abused Domain Registrars”, saying 98.7% of its domains are being used to send spam.
But AlpNames customers and regular DI readers will recall that AlpNames mysteriously went titsup in March, then got terminated by ICANN, then had its entire customer base migrated over to CentralNic in April.
So what’s this about?
I asked SpamHaus earlier this week, and it turns out that Whois query throttling is to blame.
It seems SpamHaus only pings Whois to update the registrar associated with a specific domain when the domain expires, or the name servers change, or where it’s a new registration with an unknown registrar.
I gather that when CentralNic took over AlpNames’ customer base, it did so with all the original name server information intact.
So, SpamHaus’ database still associates the domains with AlpNames even though it’s been out of business for the better part of a year.
A SpamHaus spokesperson said:
This is a very unusual situation, as a huge majority of the domains that contribute to the Top 10 list in question are created, abused, and burnt quickly; meaning a change of registrar is exceptionally rare. However, in the case of these particular domains registered with AlpNames we can only assume that the sheer volume of unused domains was too high for the owner to use in one single hit.
The actual number of “AlpNames” domains rated as spammy by SpamHaus is pretty low — 1,976 of the 2,002 domains it saw were rated as “bad”.
GMO, at #4 on the list, had over 40,000 “bad” domains, but a lower percentage given the larger number of total domains seen.
Spam is not our problem, major domain firms say ahead of ICANN 66
Eleven of the largest domain name registries and registrars have denied that spam is something they should have to deal with, unless it’s used to proliferate other types of abuse such as phishing or malware.
In a newly published “Framework to Address Abuse” (pdf), the companies attempt to define the term “DNS abuse” narrowly to capture only five (arguably only four and a half) specific types of online threat.
That abuse comprises malware, phishing, botnets, pharming and spam.
The companies agree that these are activities which registrars and registries “must” act upon.
But the document notes that not all spam is its responsibility, stating:
While Spam alone is not DNS Abuse, we include it in the five key forms of DNS Abuse when it is used as a delivery mechanism for the other four forms of DNS Abuse. In other words, generic unsolicited e-mail alone does not constitute DNS Abuse, but it would constitute DNS Abuse if that e-mail is part of a phishing scheme.
In other words, registrars and registries should not feel responsible for the billions of spams sent every day using their domains, unless the spam runs further malware, phishing, pharming or botnet abuse.
The signatories of the framework are Public Interest Registry, GoDaddy, Donuts, Tucows, Amazon Registry Services, Blacknight, Afilias, Name.com, Amazon Registrar, Neustar, and Nominet UK.
It may seem like they’ve presented a surprisingly narrow definition, but it’s in line with what current ICANN contracts dictate.
Neither the standard Registry Agreement nor Registrar Accreditation Agreement mention spam at all. Six years ago, ICANN specifically said that spam is “outside of ICANN’s scope and authority”.
Under the RA, registries have to oblige their registrars to ban registrants from “distributing malware, abusively operating botnets, phishing, piracy, trademark or copyright infringement, fraudulent or deceptive practices, counterfeiting or otherwise engaging in activity contrary to applicable law”.
They also have to maintain statistical reports on the amount of “pharming, phishing, malware, and botnets” in their zones, and provide those reports to ICANN upon demand. A recent audit found that 5% of registries, mainly dot-brands, were not doing this.
However, ICANN’s Domain Abuse Activity Reporting system, an effort to provide some transparency into how gTLDs are being abused, does in fact track spam. It does not track pharming, which is a fairly obscure and little-used form of DNS attack.
The DAAR report for September shows that spam constituted 73% of all tracked abuse.
The ICANN board of directors today identified DAAR as one of a few dozen priorities for the coming year.
Similarly, the cross-community working group known as the CCT Review Team, which was tasked with looking into how the new gTLD program has impacted competition and consumer trust, had harsh words for spam-friendly registries, and provided a definition of “DNS Security Abuse” that specifically included “high volume spam”.
The review recommended that ICANN introduce more measures to force contracted parties to deal with this type of abuse. This could include incentives for registries to clean up their zones and abuse volume thresholds that would automatically trigger compliance actions.
The new framework document comes in the context of an ongoing debate within the ICANN community about what “DNS abuse” is.
Two partners at Interisle, a security consultancy that often works for ICANN, recently guest-posted on DI to say that this term has become meaningless and should be abandoned in favor of “security threat”.
They argued that the definition should include not only spam, but also stuff like IP infringement, election interference, and terrorism.
But the main threat to contracted parties probably comes from the Governmental Advisory Committee, backed by law enforcement, which is pushing for stronger rules covering abusive content.
During a webinar last week, the US Federal Trade Commission, the FBI, and Europol argued that registries and registrars should be obliged to do more to combat abuse, specifically including spam.
“Whether or not you call it phishing or spam or whether it has a malware payload or not, ultimately it’s all email, and email remains the most common tool of cybercriminals to ensnare their victims, and that’s why we in law enforcement care about the domains used to send emails,” said Gabriel Andrews of the FBI’s Cyber Initiative Resource Fusion Unit, on the call.
Registries and registrars countered, using the same language found in the new framework, that generic spam is a content issue, and outside of their remit.
The two sides are set to clash again at ICANN’s annual general meeting in Montreal next month, in a November 6 face-to-face session.
While 11 entities signed the new framework, it’s arguably only nine companies. Name.com is owned by Donuts and both Amazon firms obviously have the same parent.
But it does include the two largest registrars, and registries responsible for running several hundred commercial gTLDs, dot-brands and ccTLDs.
While none of the signatories of the framework have a particular reputation for being spam-friendly, other companies in the industry — particularly some of the newest and cheapest new gTLDs — tend to attract spammers like flies to a turd.
Some of the signatories are perhaps surprising, given their past or ongoing behavior to tackle content-based abuse in their own zones.
Nominet, notably, takes down tens of thousands of domains ever year based on little more than police assurances that the domains are being used to sell counterfeit merchandise or infringe copyright.
The .uk registry also preemptively suspends domains based on algorithms that guess whether they’re likely to be seen as encouraging sexual violence or could be used in phishing attacks.
Donuts also has a trusted notifier relationship with the movie and music industries that has seen it take down dozens of names being used for mass copyright infringement.
PIR has previous endorsed, then unendorsed, the principal of a “UDRP for copyright”, a method of giving Big Content a way of going through due process to have domains taken or suspended.
Outside the spam issue, while the new registry-registrar framework says that registries and registrars should not get involved in matters related to web site content, it also says they nevertheless “should” (as opposed, one assumes based on the jargon usually found in internet standards, to “must”) suspend domains when they’re being used to distribute:
(1) child sexual abuse materials (“CSAM”); (2) illegal distribution of opioids online; (3) human trafficking; and (4) specific and credible incitements to violence.
These are exceptions because they constitute “the physical and often irreversible threat to human life”, the framework says.
Ultimately, this all boils down to a religious debate about where the line is drawn between “DNS” and “content”, it seems to me.
The contracted parties draw the line at threats to human life, whereas others want action on other forms of abuse largely because registries and registrars are in the best position to help.
.icu joins the million-domains club in one year, but spam triples
Another new gTLD has joined the exclusive list of those to enter seven figures in terms of domains under management.
.icu, managed by ShortDot, topped one million names this week, according to COO Kevin Kopas.
It’s taken about a month for DUM to increase from 900,000 names, and if zone files are any guide half of that growth seems to have happened in the last week.
.icu domains currently sell for between $1 and $2 for the first year at the cheap end of the market, where most regs are concentrated, with renewals closer to the $10 mark.
The gTLD joins the likes of .club, .xyz, .site and .online to cross the seven-figure threshold.
When we reported on the 900,000-reg mark at the end of May, we noted that .icu had a SpamHaus “badness” rating of 6.4%, meaning that 6.4% of all the emails coming from .icu addresses that SpamHaus saw were classified as spam.
That score was roughly the same as .com, so therefore pretty respectable.
But in the meantime, .icu’s badness score has almost tripled, to 17.4%, while .com’s has stayed about the same.
Picking through the Google search results and Alexa list for .icu domains, it appears that high-quality legit web sites are few and far between.
Whether that’s a fixable symptom of .icu’s rapid growth — it’s only about 13 months post-launch — or a predictor of poor long-term potential remains to be seen.
Phishing still on the decline, despite Whois privacy
The number of detected phishing attacks almost halved last year, despite the fact that new Whois privacy rules have made it cheaper for attackers to hide their identities.
There were 138,328 attacks in the fourth quarter of 2018, according to the Anti-Phishing Working Group, down from 151,014 in Q3, 233,040 in Q2, and 263,538 in Q1.
That’s a huge decline from the start of the year, which does not seem to have been slowed up by the introduction in May of the General Data Protection Regulation and ICANN’s Temp Spec, which together force the redaction of most personal data from public Whois records.
The findings could be used by privacy advocates to demonstrate that Whois redaction has not lead to an increase in cybercrime, as their opponents had predicted.
But the data may be slightly misleading.
APWG notes that it can only count the attacks it can find, and that phishers are becoming increasingly sophisticated in how they attempt to avoid detection. The group said in a press release:
There is growing concern that the decline may be due to under-detection. The detection and documentation of some phishing URLs has been complicated by phishers obfuscating phishing URLs with techniques such as Web-spider deflection schemes – and by employing multiple redirects in spam-based phishing campaigns, which take users (and automated detectors) from an email lure through multiple URLs on multiple domains before depositing the potential victim at the actual phishing site.
It also speculates that criminals once involved in phishing may have moved on to “more specialized and lucrative forms of e-crime”.
The Q4 report (pdf) also breaks down phishing attacks by TLD, though comparisons here are difficult because APWG doesn’t always release this data.
The group found .com to still have the most phishing domains — 2,098 of the 4,485 unique domains used in attacks, or about 47%. According to Verisign’s own data, .com only has 40% market share of total registered domains.
But new, 2012-round gTLDs had phishing levels below their market share — 4.95% of phishing on a 6.83% share. This is actually up compared to the 3% recorded by APWG in Q3 2017, the most recent available data I could find.
Only two of the top 20 most-abused TLDs were new gTLDs — .xyz and .online, which had just 70 attack domains between them. That’s good news for .xyz, which in its early days saw 10 times as much phishing abuse.
After .com, the most-abused TLD was .pw, the ccTLD for Palau run by Radix as an unrestricted pseudo-gTLD. It had 374 attack domains in Q4, APWG said.
Other ccTLDs with relatively high numbers included several African zones run as freebies by Freenom, as well as the United Kingdom’s .uk and Brazil’s .br.
Phishing is only one form of cybercrime, of course, and ICANN’s own data shows that when you take into account spam, new gTLDs are actually hugely over-represented.
According to ICANN’s inaugural Domain Abuse Activity Reporting report (pdf), which covers January, over half of cybercrime domains are in the new gTLDs.
That’s almost entirely due to spam. One in 10 of the threats ICANN analyzed were spam, as identified by the likes of SpamHaus and SURBL. DAAR does not include ccTLD data.
The takeaway here appears to be that spammers love new gTLDs, but phishers are far less keen.
ICANN did not break down which gTLDs were the biggest offenders, but it did say that 52% of threats found in new gTLDs were found in just 10 new gTLDs.
This reluctance to name and shame the worst offenders prompted one APWG director, former ICANN senior security technologist Dave Piscitello, to harshly criticize his former employer in a personal blog post last month.
Spammy .loan makes Alibaba fastest-growing and fastest-shrinking registrar in June
Chinese registrar Alibaba was both the fastest-growing and fastest-shrinking registrar in June, purely due to its dalliance with hundreds of thousands of cheap .loan domain names.
Stats compiled by DI from the latest monthly registry reports show that Alibaba’s Singapore-based registrar — which has only been active for a year — grew its domains under management by 720,669 in June, almost four times as many as second-placed NameCheap.
The huge increase was due to Alibaba’s DUM in .loan doubling in June, going from from 621,851 to 1,274,532. Another 50,000 extra domains came from .win.
Both .loan and .win are run by registry GRS Domains, the company that replaced Famous Four Media as manager of the Domain Venture Partners gTLD portfolio.
According to SpamHaus, .loan has a “badness” of just shy of 90%, based on a sample size of 45,000 observed domains. SpamHaus has .win at almost 39% bad.
GRS has promised to turn its portfolio around and cut off its deep-discounting promotions effective August 20. The June figures reflect a time when discounts were still in place.
The Singapore Alibaba had DUM of 1,771,730 at the end of June.
At the bottom end of the June league table was a second Alibaba accrediation, Beijing-based Alibaba Cloud Computing (aka HiChina or net.cn), which had a net DUM loss of 266,411, after seeing 345,268 deletes in .loan (along with 45,000 deletes in .xyz and 35,000 in .xin).
The second biggest loser was AlpNames, which is owned by the same people as Famous Four, which deleted over 114,000 names in the month. The vast majority of these names were in FFM/GRS gTLDs, including .loan.
The main, earliest Alibaba accreditation, Alibaba Cloud Computing (Beijing), which has zero exposure to new gTLDs, grew by 69,794 domains to end June as the seventh fastest-growing registrar with DUM of 7,672,594.
As of a couple weeks ago, Alibaba has a fourth ICANN accreditation, Alibaba Cloud US LLC, but that obviously does not figure into the June numbers.
Here’s the top 10 registrars for June by DUM growth:
[table id=52 /]
And the bottom 10:
[table id=53 /]
You may notice that in both tables the net change column is not equal to the sum of adds and net transfers minus deletes. This is because, per ICANN contract, domains still in their five-day Add Grace Period are counted in DUM but not in adds, so many adds slip over into the following month.
.CLUB sees spam double after China promotion
.CLUB Domains has seen the amount of spam in .club double a month after seeing a huge registration spike prompted by a deep discount deal.
The registry saw its domains under management go up by about 200,000 names over a few days in early August, largely as a result of a promotion at Chinese registrar AliBaba.
AliBaba sold .club domains for CNY 3 ($0.44) during the promotion, helping it overtake GoDaddy as the top .club registrar.
At that time, spam tracker SpamHaus was reporting that 17.9% of the .club domains it was seeing in the wild were being used in spam.
Today, that number is 35.4%, almost double the August 7 level. SpamHaus does not publish the actual number of spammy domains for .club; that honor is only bestowed upon the top 10 “bad” TLDs.
Correlation does not equal causation, of course. There could be factors other than the AliBaba promotion that contributed to the increase, but I believe there’s probably a link here.
.CLUB chief marketing officer Jeff Sass told DI:
When registrars have domains “on sale”, there is always the chance that low-cost domains will be attractive to abusers. We monitor abuse proactively, and respond promptly to complaints, as well as monitor our registrar partners collectively and individually.
It’s almost certainly unfair of me to single out fluctuations in .club here, rather than take a comparative look at multiple TLDs. There are certainly many worse TLDs per SpamHaus’ statistics — .men leads among the gTLDs, with 87.2% spam.
But, given the industry truism that cheaper domains leads to more abuse, I think such a large increase correlating with such a successful promotion is a useful data point.
Whois privacy did NOT increase spam volumes
The advent of more-or-less blanket Whois privacy has not immediately led to the feared uptick in spam, according to researchers.
Data from Cisco’s Talos email data service, first highlighted by security company Recorded Future this week, shows spam levels have been basically flat to slightly down since ICANN’s GDPR-inspired new Whois policy came into effect May 25.
Public Talos data shows that on May 1 this year there were 433.9 billion average daily emails and 370.04 billion spams — 85.28% spam.
This was down to 361.83 billion emails and 308.05 billion spams by August 1, an 85.14% spam ratio, according to Recorded Future.
So, basically no change, and certainly not the kind of rocketing skyward of spam levels that some had feared.
Cisco compiles its data from customers of its various security products and services.
Looking at Talos’ 18-month view, it appears that spam volume has been on the decline since February, when the ratio of spam to ham was pretty much identical to post-GDPR levels.
It also shows a similar seasonal decline during the northern hemisphere’s summer 2017.
There had been a fear in some quarters that blanket Whois privacy would embolden spammers to register more domains and launch more ambitious spam campaigns, and that the lack of public data would thwart efforts to root out the spammers themselves.
While that may well transpire in future, the data seems to show that GDPR has not yet had a measurable impact on spam volume at all.
Could crypto solve the Whois crisis?
Could there be a cryptographic solution to some of the problems caused by GDPR’s impact on public Whois databases? Security experts think so.
The Anti-Phishing Working Group has proposed that hashing personal information and publishing it could help security researchers carry on using Whois to finger abusive domain names.
In a letter to ICANN, APWG recently said that such a system would allow registries and registrars to keep their customers’ data private, but would still enable researchers to identify names registered in bulk by spammers and the like.
“Redacting all registration records which were formerly publicly available has unintended and undesirable consequences to the very citizens and residents that electronic privacy legislation intends to protect,” the letter (pdf) says.
Under the proposed system, each registry or registrar would generate a private key for itself. For each Whois field containing private data, the data would be added to the key and hashed using a standard algorithm such as SHA-512.
For items such as physical addresses, all the address-related fields would be concatenated, with the key, before hashing the combined value.
The resulting hash — a long string of gibberish characters — would then be published in the public Whois instead of the [REDACTED] notice mandated by current ICANN policy.
Security researchers would then be able to identify domains belonging to the same purported registrant by searching for domains containing the same hash values.
It’s not a perfect solution. Because each registry or registrar would have their own key, the same registrant would have different hash values in different TLDs, so it would not be possible to search across TLDs.
But that may not be a huge problem, given that bad guys tend to bulk-register names in TLDs that have special offers on.
The hashing system may also be beneficial to interest groups such as trademark owners and law enforcement, which also look for registration patterns when tracking down abuse registrants.
The proposal would create implementation headaches for registries and registrars — which would actually have to build the crypto into their systems — and compliance challenges for ICANN.
The paper notes that ICANN would have to monitor its contracted parties — not all of which may necessarily be unfriendly to spammers — to make sure they’re hashing the data correctly.
