building-attack-pattern-library-from-cti-reports

building-attack-pattern-library-from-cti-reports is a skill for Claude Code, Codex from andycungkrinx91/konoha. It costs 44 tokens per session (3,051 once invoked), scanned C, a copy of building-attack-pattern-library-from-cti-reports, MIT.

A workflow for turning cyber threat intelligence reports into a structured library of attacker techniques. It maps those techniques to MITRE ATT&CK, a public knowledge base of adversary behavior, and stores them in STIX, a standard format for sharing threat data.

In plain words
What is it for?
It helps security teams catalog tactics, techniques, and threat actors, organize them by behavior, and create starting templates for detection rules.
Why use it?
It removes the need to extract and organize techniques manually from reports, making threat information easier to search and use consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

building-attack-pattern-library-from-cti-reports scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/agent.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Building Attack Pattern Library from CTI Reports

Overview

Cyber threat intelligence (CTI) reports from vendors like Mandiant, CrowdStrike, Talos, and Microsoft contain detailed descriptions of adversary behaviors that can be extracted, normalized, and cataloged into a structured attack pattern library. This skill covers parsing CTI reports to extract adversary techniques, mapping behaviors to MITRE ATT&CK technique IDs, creating STIX 2.1 Attack Pattern objects, building a searchable library indexed by tactic, technique, and threat actor, and generating detection rule templates from documented patterns.

When to Use

  • When deploying or configuring building attack pattern library from cti reports capabilities in your environment
  • When establishing security controls aligned to compliance requirements
  • When building or improving security architecture for this domain
  • When conducting security assessments that require this implementation

Prerequisites

  • Python 3.9+ with stix2, mitreattack-python, spacy, requests libraries
  • Collection of CTI reports (PDF, HTML, or text format)
  • MITRE ATT&CK STIX data (local or via TAXII)
  • Understanding of ATT&CK technique structure and naming conventions
  • Familiarity with detection engineering concepts (Sigma, YARA)

Key Concepts

Attack Pattern Extraction

CTI reports describe adversary behaviors in natural language. Extraction involves identifying action verbs and technical terms that map to ATT&CK techniques, recognizing tool names and malware families, identifying infrastructure indicators, and mapping sequences of behaviors to attack chains (kill chain phases).

STIX 2.1 Attack Pattern Objects

STIX defines Attack Pattern as a Structured Domain Object (SDO) that describes ways threat actors attempt to compromise targets. Each pattern links to ATT&CK via external references, includes kill chain phases (tactics), and can be related to Intrusion Sets, Malware, and Tool objects.
