Infoblox Threat Intel Discovers Muddling Meerkat, a DNS Operation Controlling China's Great Firewall

The moniker "Muddling Meerkat'' was given to describe the actor as an animal that appears cute, but in reality it can be dangerous, living in a complex network of burrows underground, and out of view. From a technical perspective, "Meerkat" references the abuse of open resolvers, particularly through the use of DNS mail exchange (MX) records. "Muddling" refers to the bewildering nature of their operations.

With a deep understanding of and visibility into DNS, Infoblox Threat Intel can see attacker infrastructure as it's created, stopping both known and emerging threats earlier. With 46M unique threat indicators detected in 2023 and a practically non-existent false positive rate of 0.0002%, Infoblox Threat Intel detected 82% of threats before or at the first query thus far in 2024 leveraging our patent pending threat intelligence system along with Infoblox's new Zero Day DNS capability. The threat actor, Muddling Meerkat, has been operating covertly since at least October 2019. At first glance, its operations look like Slow Drip distributed denial-of-service (DDoS) attacks, however, it is unlikely DDoS is their ultimate goal. The motivation of the actor is unknown, though they may be performing reconnaissance or prepositioning for future attacks.

Muddling Meerkat demonstrates a sophisticated understanding of DNS that is uncommon among threat actors today - clearly pointing out that DNS is a powerful weapon leveraged by adversaries.

The research further shows that their operations:

Infoblox Threat Intel Gets a Bold New Look, Demonstrating Industry-Leading Commitment to DNS Threat Intelligence

Infoblox Threat Intel is the leading creator of original DNS threat intelligence in the market today. The group, led by Dr. Renée Burton, a 22-year veteran of NSA, is composed of researchers across five countries who have deep expertise in DNS, data science, ML/AI, intelligence analysis, software reverse engineering, and malicious spam detection. Infoblox put a new focus on the team's public identity to distinguish itself from the sea of threat intel aggregators - highlighting its expertise in original DNS threat research.

Throughout the past year, Infoblox Threat Intel was the first to report other DNS threat actors, all of which had gone undetected for over a year by the rest of the industry. These include DNS C2 malware toolkit Decoy Dog, malicious link shortening service provider Prolific Puma, the most extensive known cybercriminal traffic distribution system VexTrio Viper (aka VexTrio), and DNS CNAME redirection network provider Savvy Seahorse. These publications represent a small fraction of the number of DNS threat actors Infoblox Threat Intel has discovered and are tracking.

"The sheer mass of threat actors effectively hiding in the DNS should be a wakeup call for every defender to make DNS threat intelligence an essential part of their strategy," added Burton. "Why? Because more than 92%² of malware utilizes DNS."

The most effective way to protect against these sophisticated threats is with DNS Detection and Response systems like Infoblox's BloxOne^® Threat Defense. Unlike other security solutions that are malware and post-event centric, Infoblox Threat Intel uses a multi-pronged approach to discover threats in DNS.

Introducing Zero Day DNS, the Newest Feature within BloxOne Threat Defense

Infoblox's new cloud-based Zero Day DNS™ augments the existing methods to detect and block possible threats from domains that are registered by threat actors just minutes to hours before being used in an attack. It is a zero trust model for DNS that leverages the extensive visibility Infoblox has to rapidly adjudicate hundreds of thousands of new domains in near real time every day.

While most domains are aged before they are used by attackers, Infoblox has discovered an alarming trend over the last 18 months, where threat actors register lookalike domains and immediately use them in targeted attacks. Zero Day DNS was designed specifically to address this risk.

Zero Day DNS is tailored to individual customer networks, providing a new form of custom threat intel for Infoblox BloxOne Threat Defense Advanced Cloud customers. This capability provides the earliest defense against spearphishing attacks, which were responsible for 66% of all data breaches in 2023 according to Barracuda Networks annual report on phishing trends.¹ Initial results show that Zero Day DNS can detect novel threats without risk of blocking vital network access. Over 16% of the flagged domains were deemed malicious within 48 hours by other analytics.

"Zero Day DNS is not just a nice to have, but a strategic advantage in an environment where threat actors, particularly ransomware actors, are using a domain immediately after registration for spearphishing," added Burton.

Meet Infoblox Threat Intel

Dr. Burton will discuss Muddling Meerkat at the RSA Conference in San Francisco, May 6-9. Live sessions will be held at Booth S-726. Visit this here to request a meeting with Infoblox at RSAC 2024.

Additionally, Dr. Burton is hosting a webinar titled: Infoblox Threat Intel – Disrupting Cybercrime Where it Begins – DNS, on May 8 at 10 am PDT. Register to attend here.
