Develop Capabilities

T1587 · resource-development

Adversaries may build capabilities that can be used during targeting. Rather than purchasing, freely downloading, or stealing capabilities, adversaries may develop their own capabilities in-house. This is the process of identifying development requirements and building solutions such as malware, exploits, and self-signed certificates.

Adversaries may develop capabilities to support their operations throughout numerous phases of the adversary lifecycle. As with legitimate development efforts, different skill sets may be required for developing capabilities. The skills needed may be located in-house, or may need to be contracted out.

Use of a contractor may be considered an extension of that adversary's development capabilities, provided the adversary plays a role in shaping requirements and maintains a degree of exclusivity to the capability.

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.

Detection Coverage

2/6 layers
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).
