tracking-adversary-infrastructure

tracking-adversary-infrastructure is a skill for Claude Code, Codex from meltedinhex/analyst-ai-pack. It costs 67 tokens per session (627 once invoked), scanned A, original, Apache-2.0.

An infrastructure-tracking workflow that groups suspected command-and-control or staging servers by shared technical details, such as certificates, network providers, ports, or browser icons. Command-and-control servers are systems an attacker uses to communicate with compromised machines.

In plain words
What is it for?
Use it to cluster hosts, find related infrastructure in scan data, score how closely they match, and record confidence in the results.
Why use it?
It helps expand a few known indicators into a broader set of related hosts. Shared details suggest relationships but do not prove that the same attacker owns every host.

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

tracking-adversary-infrastructure scanned grade A with 0 findings 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/analyst.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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Tracking Adversary Infrastructure

When to Use

  • You have a set of suspected C2/staging hosts with attributes (JARM/JA3S, TLS cert fields, favicon hash, ASN, ports, registrar) and want to cluster them to find related infrastructure.
  • You are expanding from a few known indicators to the adversary's broader footprint.

Do not use clustering as confirmed attribution — shared hosting/attributes can be coincidental. Corroborate before attributing.

Prerequisites

  • Host records (CSV/JSON) with shared-attribute fields to cluster on.

Workflow

Step 1: Cluster on shared attributes

python scripts/analyst.py cluster hosts.json --attrs jarm,cert_cn,favicon_hash,asn

Groups hosts that share one or more pivot attributes into clusters, defanging host indicators.

Step 2: Score cluster cohesion

Rank clusters by how many distinct attributes the members share (more shared attributes → stronger relationship).

Step 3: Expand and confirm

Use the strongest shared attributes (e.g., a unique self-signed cert CN or favicon hash) to pivot in internet-scan data for more hosts; corroborate.

Step 4: Document

Record clusters, the shared pivots, and confidence; feed confirmed indicators to detection.

Validation

  • Clustering keys on explicit shared attributes, not loose similarity.
  • Cluster strength reflects the count of distinct shared attributes.
  • Host indicators are defanged in output.

Pitfalls

  • Common CDN/cloud JARM/ASN values creating huge false clusters — exclude generic pivots.
  • Default certificates shared by unrelated servers.
  • Treating one weak shared attribute as a strong link.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

tracking-adversary-infrastructure is a skill published in the GitHub repository meltedinhex/analyst-ai-pack (22 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 67 tokens to every session and 627 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
