building-adversary-infrastructure-tracking-system

building-adversary-infrastructure-tracking-system is a skill for Claude Code, Codex from andycungkrinx91/konoha. It costs 44 tokens per session (3,049 once invoked), scanned A, a copy of building-adversary-infrastructure-tracking-system, MIT.

A system for finding and tracking suspected attacker infrastructure using passive DNS, certificate records, domain-registration data, and IP information. It links related domains, servers, certificates, and hosting providers into a changing map.

In plain words
What is it for?
It helps analysts discover related domains and servers, monitor new registrations, identify reused infrastructure, and maintain threat-actor network maps.
Why use it?
It reduces the manual work of following connections between known indicators and newly appearing infrastructure.

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 A, and why

building-adversary-infrastructure-tracking-system scanned grade A 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 Adversary Infrastructure Tracking System

Overview

Adversary infrastructure tracking uses passive DNS records, certificate transparency logs, WHOIS registration data, and IP enrichment to discover, map, and monitor threat actor command-and-control (C2) networks. Attackers frequently reuse hosting providers, registrars, SSL certificates, and naming patterns across campaigns, enabling analysts to pivot from known indicators to discover new infrastructure. This skill covers building an automated tracking system that identifies infrastructure relationships, detects newly registered domains matching adversary patterns, and maintains a continuously updated map of threat actor networks.

When to Use

  • When deploying or configuring building adversary infrastructure tracking system 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 requests, dnspython, python-whois, shodan, networkx libraries
  • API keys: SecurityTrails, PassiveTotal/RiskIQ, Shodan, VirusTotal
  • Access to passive DNS data sources
  • Understanding of DNS infrastructure, hosting, and domain registration
  • Graph database (Neo4j) or NetworkX for relationship visualization

Key Concepts

Passive DNS

Passive DNS captures historical DNS resolution data, recording which domains resolved to which IPs and when. Unlike active DNS queries, passive DNS preserves historical relationships even after records change, enabling analysts to track infrastructure changes, identify shared hosting patterns, and discover related domains that resolved to the same IP addresses over time.

Infrastructure Pivoting

Pivoting identifies related infrastructure by following connections: IP pivot (find all domains on an IP), domain pivot (find all IPs a domain resolved to), WHOIS pivot (find domains with same registrant), certificate pivot (find hosts sharing SSL certificates), and NS/MX pivot (find domains using same name servers or mail servers).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
