Search Open Technical Databases: WHOIS
Other sub-techniques of Search Open Technical Databases (5)
Adversaries may search public WHOIS data for information about victims that can be used during targeting. WHOIS data is stored by regional Internet registries (RIR) responsible for allocating and assigning Internet resources such as domain names. Anyone can query WHOIS servers for information about a registered domain, such as assigned IP blocks, contact information, and DNS nameservers.(Citation: WHOIS) Adversaries may search WHOIS data to gather actionable information. Threat actors can use online resources or command-line utilities to pillage through WHOIS data for information about potential victims. Information from these sources may reveal opportunities for other forms of reconnaissance (ex: Active Scanning or Phishing for Information), establishing operational resources (ex: Acquire Infrastructure or Compromise Infrastructure), and/or initial access (ex: External Remote Services or Trusted Relationship).

Pre-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. This mitigation can be implemented through the following measures: 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. |
Обнаружение
Much of this activity may have a very high occurrence and associated false positive rate, as well as potentially taking place outside the visibility of the target organization, making detection difficult for defenders. Detection efforts may be focused on related stages of the adversary lifecycle, such as during Initial Access.
