Weekly Update 349

By Troy Hunt
Weekly Update 349

This week's update is dominated by my experience with "Lena", the scammer from Gumtree who tried to fleece my wife of $800. There's a blow-by-blow rundown of how it all happened in this video and it's fascinating to think that these things can actually be successful given all the red flags. But they are, and in Australia alone innocent victims are stung to the tune of more than 3 billion dollars every year by fraudsters which is a staggering number. Understanding how these scams work and sharing that knowledge broadly with the less technical of those around us is part of how to combat this, so please share the tweet thread generously... and enjoy the entertainment 😊

Phishing Domains Tanked After Meta Sued Freenom

By BrianKrebs

The number of phishing websites tied to domain name registrar Freenom dropped precipitously in the months surrounding a recent lawsuit from social networking giant Meta, which alleged the free domain name provider has a long history of ignoring abuse complaints about phishing websites while monetizing traffic to those abusive domains.

The volume of phishing websites registered through Freenom dropped considerably since the registrar was sued by Meta. Image: Interisle Consulting.

Freenom is the domain name registry service provider for five so-called “country code top level domains” (ccTLDs), including .cf for the Central African Republic; .ga for Gabon; .gq for Equatorial Guinea; .ml for Mali; and .tk for Tokelau.

Freenom has always waived the registration fees for domains in these country-code domains, but the registrar also reserves the right to take back free domains at any time, and to divert traffic to other sites — including adult websites. And there are countless reports from Freenom users who’ve seen free domains removed from their control and forwarded to other websites.

By the time Meta initially filed its lawsuit in December 2022, Freenom was the source of well more than half of all new phishing domains coming from country-code top-level domains. Meta initially asked a court to seal its case against Freenom, but that request was denied. Meta withdrew its December 2022 lawsuit and re-filed it in March 2023.

“The five ccTLDs to which Freenom provides its services are the TLDs of choice for cybercriminals because Freenom provides free domain name registration services and shields its customers’ identity, even after being presented with evidence that the domain names are being used for illegal purposes,” Meta’s complaint charged. “Even after receiving notices of infringement or phishing by its customers, Freenom continues to license new infringing domain names to those same customers.”

Meta pointed to research from Interisle Consulting Group, which discovered in 2021 and again last year that the five ccTLDs operated by Freenom made up half of the Top Ten TLDs most abused by phishers.

Interisle partner Dave Piscitello said something remarkable has happened in the months since the Meta lawsuit.

“We’ve observed a significant decline in phishing domains reported in the Freenom commercialized ccTLDs in months surrounding the lawsuit,” Piscitello wrote on Mastodon. “Responsible for over 60% of phishing domains reported in November 2022, Freenom’s percentage has dropped to under 15%.”

Interisle collects data from 12 major blocklists for spam, malware, and phishing, and it receives phishing-specific data from Spamhaus, Phishtank, OpenPhish and the APWG Ecrime Exchange. The company publishes historical data sets quarterly, both on malware and phishing.

Piscitello said it’s too soon to tell the full impact of the Freenom lawsuit, noting that Interisle’s sources of spam and phishing data all have different policies about when domains are removed from their block lists.

“One of the things we don’t have visibility into is how each of the blocklists determine to remove a URL from their lists,” he said. “Some of them time out [listed domains] after 14 days, some do it after 30, and some keep them forever.”

Freenom did not respond to requests for comment.

This is the second time in as many years that a lawsuit by Meta against a domain registrar has disrupted the phishing industry. In March 2020, Meta sued domain registrar giant Namecheap, alleging cybersquatting and trademark infringement.

The two parties settled the matter in April 2022. While the terms of that settlement have not been disclosed, new phishing domains registered through Namecheap declined more than 50 percent the following quarter, Interisle found.

Unfortunately, the lawsuits have had little effect on the overall number of phishing attacks and phishing-related domains, which have steadily increased in volume over the years.  Piscitello said the phishers tend to gravitate toward registrars that offer the least resistance and lowest price per domain. And with new top-level domains constantly being introduced, there is rarely a shortage of super low-priced domains.

“The abuse of a new top-level domain is largely the result of one registrar’s portfolio,” Piscitello told KrebsOnSecurity. “Alibaba or Namecheap or another registrar will run a promotion for a cheap domain, and then we’ll see flocking and migration of the phishers to that TLD. It’s like strip mining, where they’ll buy hundreds or thousands of domains, use those in a campaign, exhaust that TLD and then move on to another provider.”

Piscitello said despite the steep drop in phishing domains coming out of Freenom, the alternatives available to phishers are many. After all, there are more than 2,000 accredited domain registrars, not to mention dozens of services that let anyone set up a website for free without even owning a domain.

“There is no evidence that the trend line is even going to level off,” he said. “I think what the Meta lawsuit tells us is that litigation is like giving someone a standing eight count. It temporarily disrupts a process. And in that sense, litigation appears to be working.”
