The Hidden Battlefield: Why DNS Is the Frontline of Emerging Cyber Threats

In today’s rapidly evolving digital landscape, cyberattacks are becoming increasingly sophisticated and dangerous. Artificial Intelligence (AI) has driven unparalleled levels of innovation and operational excellence, but at the same time, it has become a “weapon” in the hands of cybercriminals. The financial impact is already enormous: global damages from cyberattacks are expected to reach $10.5 trillion by the end of 2025—a staggering 300% increase compared to 2015*. ENISA also supports this projection, highlighting that 90% of European organizations expect a further surge in cyberattacks within the next year.

Malicious actors such as hackers are now leveraging AI to broaden and enhance their attacks, making the fight against them more challenging than ever. One of the most underestimated yet critical points of vulnerability is the Domain Name System (DNS)—the “phonebook” of the internet. The DNS translates domain names such as example.com into IP addresses used by computers to communicate with one another. Because of its fundamental role, DNS is often a prime target for cyberattacks.

DNS as a Weapon in the Hands of Attackers

DNS-level attacks are not a new threat, but their scale and complexity have multiplied with the advent of AI and automation. These threats include:

• DNS Tunneling: Hiding malicious data within seemingly legitimate DNS queries.
• DNS Beaconing: Covert communication between a compromised system and an attacker’s command-and-control server.
• Fast Flux and DGA domains: Using dynamically changing or automatically generated domains to evade detection.
• Malicious Newly Registered Domains (NRDs): Websites created for phishing, spam, or malware that disappear within hours.

The common factor in these attacks? They often go completely unnoticed by traditional SIEM, EDR, or firewall solutions because these tools typically don’t analyze or inspect DNS traffic itself.

What’s at Stake Without DNS Protection

The majority of ransomware and data exfiltration incidents begin with DNS communication. When this is bypassed, attacks unfold without warning—until it’s too late.

Traditional defenses are no longer enough. Today, true cyber resilience requires visibility into DNS. Without DNS protection, organizations miss critical signs of compromise. For example:

• AI-powered phishing domains are created and disappear within minutes.
• Malware command-and-control (C2) instructions are transmitted through unmonitored DNS.

To protect against attacks that exploit DNS, organizations must adopt strategies that integrate real-time monitoring and analysis of DNS queries. This includes implementing robust security policies to control DNS requests and enabling advanced anomaly detection mechanisms to identify abnormal patterns such as DNS tunneling or beaconing.

Additionally, securely logging DNS queries and integrating them with existing solutions like SIEM systems is essential for timely analysis, detection, and response to threats.

However, as attacks evolve rapidly, traditional protection methods often fall short of preventing these attacks from reaching organizations’ networks and systems.

The New Line of Defense: Resilience with DNS Visibility

DNS protection is critical for:

• Maintaining availability and performance
• Preventing advanced threats
• Protecting sensitive data
• Ensuring user trust and regulatory compliance

At Odyssey, we recognized this critical need—and we address it with ClearSkies™ DNS Shield, a cloud-native solution that delivers real-time detection and mitigation of DNS threats.

ClearSkies™ DNS Shield is not just another tool—it is a strategic weapon in the cyber resilience arsenal.

Key Benefits:

• Enhanced visibility into DNS activity
• Proactive threat mitigation
• Detection of AI-based or signature-less threats
• Reduced attack surface and fewer entry points for attackers
• Improved compliance with regulatory requirements
• Operational continuity by preventing DNS-based cyberattack disruptions

DNS security is no longer optional—it is the first line of defense in modern cybersecurity strategies. By integrating robust DNS protection into your security architecture, you not only block threats at an early stage but also gain deep visibility and control over one of the most vulnerable and widely used layers of your network.

In this context, the message to organizations is clear: if you can’t see what’s happening in DNS, you’re already exposed.
