DNS Under Siege: Rising Cyber Threats Exploit Critical Network Protocol
  • DNS is a critical protocol for network functionality, yet it is often inadequately monitored, making it a prime target for cyber attacks.

  • Attacks leveraging DNS pose significant business risks, including data loss, downtime, and reputational damage, underscoring the urgent need for robust DNS security measures.

  • Phishing and malware distribution via DNS are on the rise, with attackers using domain generation algorithms (DGAs) to create numerous fake domains, complicating defense strategies.

  • Attackers are increasingly utilizing trusted protocols like HTTPS and DNS over HTTPS (DoH) to carry out attacks, which complicates detection efforts for enterprises.

  • The misuse of DoH contributes to the challenge of detecting malicious activities, as encryption can mask harmful traffic from monitoring tools.

  • Enterprises are advised to review their use of DoH to maintain visibility and control over DNS traffic, including logging DNS activity.

  • CISOs are urged to treat DNS as a crucial security data source to identify early signs of compromise and implement advanced DNS-layer defenses.

  • Techniques used in DNS attacks are evolving, with DNS tunneling becoming more prevalent, allowing attackers to transmit data covertly through DNS queries.

  • The report advocates for enhanced collaboration between network and security teams to improve visibility and response to DNS-related threats.

  • The 2025 DNS Threat Landscape Report by Infoblox reveals that threat actors are increasingly exploiting DNS for data exfiltration, evasion of defenses, and malware delivery.
