ATT&CK Technique

DNS Server

T1584.002 · resource-development

Adversaries may compromise third-party DNS servers that can be used during targeting. During post-compromise activity, adversaries may utilize DNS traffic for various tasks, including for Command and Control (ex: Application Layer Protocol). Instead of setting up their own DNS servers, adversaries may compromise third-party DNS servers in support of operations.

By compromising DNS servers, adversaries can alter DNS records. Such control can allow for redirection of an organization's traffic, facilitating Collection and Credential Access efforts for the adversary. Additionally, adversaries may leverage such control in conjunction with Digital Certificates to redirect traffic to adversary-controlled infrastructure, mimicking normal trusted network communications.

Alternatively, they may be able to prove ownership of a domain to a SaaS service in order to assert control of the service or create a new administrative Cloud Account. Adversaries may also be able to silently create subdomains pointed at malicious servers without tipping off the actual owner of the DNS server.

Mitigations

1
MITRE ATT&CK mitigations - vendor-agnostic guidance for reducing exposure to this technique.
M1056Pre-compromise

Pre-compromise mitigations involve proactive measures and defenses implemented to prevent adversaries from successfully identifying and exploiting weaknesses during the Reconnaissance and Resource Development phases of an attack. These activities focus on reducing an organization's attack surface, identify adversarial preparation efforts, and increase the difficulty for attackers to conduct successful operations.

Limit Information Exposure
  • Regularly audit and sanitize publicly available data, including job posts, websites, and social media.
  • Use tools like OSINT monitoring platforms (e.g., SpiderFoot, Recon-ng) to identify leaked information.
Protect Domain and DNS Infrastructure
  • Enable DNSSEC and use WHOIS privacy protection.
  • Monitor for domain hijacking or lookalike domains using services like RiskIQ or DomainTools.
External Monitoring
  • Use tools like Shodan, Censys to monitor your external attack surface.
  • Deploy external vulnerability scanners to proactively address weaknesses.
Threat Intelligence
  • Leverage platforms like MISP, Recorded Future, or Anomali to track adversarial infrastructure, tools, and activity.
Content and Email Protections
  • Use email security solutions like Proofpoint, Microsoft Defender for Office 365, or Mimecast.
  • Enforce SPF/DKIM/DMARC policies to protect against email spoofing.
Training and Awareness
  • Educate employees on identifying phishing attempts, securing their social media, and avoiding information leaks.

Coverage across standard detection surfaces. Rows marked none have no rule of that type mapped. Some are real blind spots worth closing; others are simply not applicable to this technique (e.g. YARA matches malware files, not network behaviour).
