The article discusses the emergence of 'Muddling Meerkat,' a highly sophisticated Chinese state actor utilizing DNS vulnerabilities to bypass security measures, redirect users to malicious sites, launch DDoS attacks, and manipulate domain resolutions for surveillance and data theft. The threat involves generating massive distributed DNS queries through open resolvers globally, with Infoblox's proactive discovery and blocking of the actors' domains showcasing the importance of advanced detection and response capabilities to combat such threats. Termed 'Muddling Meerkat' due to its mysterious operations and use of unique tactics, the actor's deep understanding of DNS highlights the significance of securing domain systems
With indications of a reconnaissance-related motive, the threat actor has been active since 2019, showcasing a high-level attack on the DNS system and demonstrating a unique approach involving old domains, MX records, and Chinese IP ranges to evade detection. Researchers attribute MX record responses from Chinese IP addresses to the Great Firewall, stressing the need for vigilance and advanced cybersecurity measures against such advanced DNS-based threats. https://cybersecuritynews.com/dns-muddling-meerkat-cyber-weapon/
