While threat actors can use any domain across thousands of top-level domains (TLDs), they often have favorites. For instance, you may be familiar with Spamhaus's 10 most-abused TLDs for spamming. WhoisXML API researchers recently built on this list by analyzing 40,000 newly registered domains (NRDs) that sported some of the listed unreputable TLDs. We called this study "DNS Abuse Trends: Dissecting the Domains Under the Most-Abused TLDs."
Brand impersonation happens much more often than people realize. In CSC's latest Domain Security Report, we found that 75% of domains for the Global 2000 that contained more than six characters from the brand names were not actually owned by the brands themselves. The intent of these fake domain registrations is to leverage the trust placed on the targeted brands to launch phishing attacks, other forms of digital brand abuse, or IP infringement...
The DNS Abuse Institute recently published our sixth monthly report for our project to measure DNS Abuse: DNSAI Compass ('Compass'). Compass is an initiative of the DNS Abuse Institute to measure the use of the DNS for phishing and malware. The intention is to establish a credible source of metrics for addressing DNS Abuse. We hope this will enable focused conversations, and identify opportunities for improvement.
In the first article of this two-part blog series, we looked at how frequently domains were used by bad actors for phishing activity across individual top-level domains (TLDs) or domain extensions, using data from CSC's Fraud Protection services, powered by our DomainSecSM platform. In this second article, we analyze multiple datasets to determine the highest-threat TLDs, based on the frequency with which the domains are used egregiously for a range of cybercrimes.
A domain name consists of two main elements: the second-level domain name to the left of the dot - often consisting of a brand name or relevant keywords - and the domain extension or top-level domain (TLD) to the right of the dot. Domain names form the key elements of the readable web addresses allowing users to access pages on the internet and also allowing the construction of email addresses.
At the beginning of 2023, the good news is that, in spite of all geopolitical tensions, the Internet infrastructure built around TCP/IP continues to carry emails, web pages, videos, and podcasts across the globe. Technically, the Internet remains robust. The bad news is that more and more digital borders will continue to affect the global nature of international digital communication...
Domain name abuse is one of the most dangerous and under-regulated issues in digital business security today. An attack on a web domain can lead to the redirection of a company's website, domain spoofing, phishing attacks, network breaches, and business email compromise (BEC). Domains used as a company's online world are part of an organization's external attack surface and need to be continuously monitored for cybercrime attacks and fraud.
More and more information is becoming available about the breach of Optus (Australia's second-largest telco). It looks like the hacker is more of an amateur than a professional criminal or a "state actor." This makes the hack even more worrisome. It looks as though Optus didn't have its security house in order. This makes the issue all the more painful for the company. It will dent its reputation, and customers could become somewhat wary about dealing with the company.

We’ve noted in previous CSC studies that phishing continues to be an extremely popular threat vector with bad actors and shows no signs of subsiding in part, because of the COVID–19 pandemic and the rise in popularity of remote working. Indeed, the most recent figures from the Anti-Phishing Working Group (APWG) show that the numbers of phishing attacks are higher than ever before, with the quarterly total of identified unique phishing attacks exceeding 1 million for the first time in Q1 2022, and over 600 distinct brands attacked each month.
