- Hackers are using DNS vulnerabilities to launch sophisticated cyber attacks.
- Infoblox researchers discovered “Muddling Meerkat,” a Chinese state actor manipulating DNS to bypass security measures.
Hackers are exploiting DNS vulnerabilities to redirect users to malicious websites, launch DDoS attacks, and manipulate domain resolutions for surveillance or data theft purposes. Infoblox researchers recently uncovered the “Muddling Meerkat” threat, attributed to a Chinese state actor, which bypasses security measures by generating distributed DNS query volumes and utilizing Chinese-controlled national internet infrastructure. This operation underscores the importance of strong detection and response capabilities against advanced DNS-based threats.
Infoblox proactively blocked the actor’s domains, showcasing their ability to track and defend against this emerging cyber threat. The attack involves hiding tactics through open resolvers and MX records, highlighting the actor’s deep understanding of DNS operations. The Meerkat campaign has been active since 2019, with its true intentions related to reconnaissance. By using sophisticated methods such as old domains and non-MX records, threat actors are able to evade detection mechanisms and provoke reactions from China’s Great Firewall.
Overall, the Muddling Meerkat threat demonstrates the need for heightened cybersecurity measures, particularly in protecting the domain name system from such advanced attacks. By leveraging AI and advanced data science, researchers were able to uncover and combat this DNS-based threat, emphasizing the evolving nature of cyber threats and the importance of proactive defense strategies.
