7 Most Popular Blogs of Q1 2024


Spring is in full bloom (pun completely intended)! DomainTools kept busy in Q1 with events and conferences including AFCEA West and FIC and we’re gearing up for RSA as we speak – we hope to see you there! 

The Breaking Badness Cybersecurity Podcast was joined by some fantastic guests including Allan Liska and Jon DiMaggio (who joined us for our Book Club series) and Yelisey Bohuslavskiy of RedSense joined Kali Fencl and Austin Northcutt to discuss ransomware and mortgage brokers. Yelisey also joined DomainTools Security Advisor, Malachi Walker, for a healthcare-focused webinar which you can watch on-demand. 

Now let’s get into blog posts! If you’re new to this series, each quarter we share the top posts your peers in the space have found to be interesting, educational, or fun. If you haven’t been able to keep up with our weekly posts, this is a great opportunity for a high-level view of what those in the industry have enjoyed from DomainTools.

Top Blog Posts from DomainTools in Q1 2024

Finding New ASNs

We’re kicking things off with a blog post that was published right as we came back from the holidays. In this article, Joe St Sauver discusses how new or “reanimated” ASNs might be staged for legitimate purposes, but some might be created for more nefarious purposes. Either way, a newly-created ASN is worth a closer look.

Going From An IP Address to a Fully Qualified Domain Name (FQDN)

Another piece from Joe St Sauver takes a top slot on our list! This is one we see time and time again on here. This piece is part of a short series (the first being “Going From A Domain Name to IP Address in DNSDB: Some “Pro Tips” To Keep In Mind”). While that article begins with a fully qualified domain name (FQDN) resolving to its IP address, this article goes in the opposite direction of using Farsight DNSDB to go from an IP address to a FQDN. 

New Report Helps Users Bring Up a Secure Virtual Private Server Under Debian 11

Wow! THREE articles from Joe St Sauver? This blog post is a summary of a white paper available for download. While you can get a Un*x virtual private server cheaply and easily today, there are still MANY details associated with bringing up a functional and secure system. This report is meant to help users bring up a secure-yet-still-usable system.

7 Most Popular Blogs of Q4 2023

To have a Most Popular Blogs blog on our Most Popular Blogs list…so meta, but we love it. We covered a lot of ground in Q4 including our analysis of a US Postal Service smishing campaign, our post created for CISA’s Cybersecurity Awareness Month, hunting subdomains at DEFCON 31, and more!

Finding Patterns That Only Match Registered Domains (and Which Don’t “Overmatch” Against Subdomains)

Joe St Sauver was on fire in Q1! You may want to match domains that have a particular string followed by a TLD, but run into problems with “overmatching.” In this article, we’ll show you how to use Farsight DNSDB to find such a set of domains quickly.

Elevate Your Cyber Defense with the Cortex XSOAR and DomainTools Integration

This is Anthony Johnson’s first article since joining DomainTools! It explores how the integration of DomainTools with Palo Alto’s Cortex XSOAR provides a proactive and dynamic defense system for organizations.

Need A New PC? Buy One That’s Prebuilt (Rather Than Building One Yourself)

Building your own computer can be a rewarding experience, allowing you to “get your hands dirty” with all of the individual components. It allows you to determine for yourself which specific parts you want and how much you’re willing to spend. Although, as shown by the length of this article, it is a more involved experience rather than buying a pre-built machine. Final nod to Joe St Sauver for 5 posts in the Top Blogs list!

Next Up: Q2 2024!

As mentioned earlier, we’ll be at RSA and we’re excited for other upcoming shows including AFCEA TechNet, Splunk .conf, and more! We’ll also be sharing new research and we’ve got some great live presentations in the works, so stay tuned!
