hunt-threat

hunt-threat is a skill for Claude Code, Codex from dandye/ai-runbooks. It costs 49 tokens per session (1,394 once invoked), scanned A, original, Apache-2.0.

A proactive security investigation workflow driven by a clear hypothesis, such as suspected DNS tunnelling or unusual PowerShell use. Threat hunting means searching existing logs and intelligence for signs of an attack that alerts may have missed.

In plain words
What is it for?
Use it to investigate threat techniques, intelligence reports, anomalies, or suspicious activity over a selected time period. It supports scoped queries, iterative searches, pivots, and case documentation.
Why use it?
It gives experienced analysts a repeatable way to define the suspected behaviour, search relevant systems, and document findings.

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

hunt-threat 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 13d ago.

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.

Advanced Threat Hunting Skill

Conduct proactive, hypothesis-driven threat hunts based on threat intelligence, observed anomalies, or specific TTPs.

Inputs

  • HUNT_HYPOTHESIS - Clear statement of the hunt objective (required)
    • Example: "Suspected DNS tunneling for C2 based on recent actor TTPs"
    • Example: "Anomalous PowerShell execution on critical servers"
    • Example: "Living-off-the-land techniques bypassing EDR"
  • (Optional) RELEVANT_GTI_REPORTS - GTI Collection IDs or report names
  • (Optional) TARGET_SCOPE_QUERY - UDM query to narrow initial scope
  • TIME_FRAME_HOURS - Lookback period (default: 168 = 7 days)
  • (Optional) HUNT_CASE_ID - case for tracking the hunt

Workflow

Step 1: Define Hypothesis & Scope

Clearly articulate:

  • What threat behavior are we looking for?
  • What would evidence of this look like in logs?
  • What systems/users are in scope?
  • What time period is relevant?

Create or identify HUNT_CASE_ID for documentation.

Step 2: Deep Intelligence Analysis

For each relevant GTI report:

gti-mcp.get_collection_report(id=REPORT_ID)
gti-mcp.get_entities_related_to_a_collection(id=REPORT_ID, relationship_name="attack_techniques")
gti-mcp.get_collection_timeline_events(id=REPORT_ID)
gti-mcp.get_collection_mitre_tree(id=REPORT_ID)

Also:

gti-mcp.get_threat_intel(query="Details on specific TTPs")

Step 3: Develop Initial Hunt Queries

Based on hypothesis and intelligence, formulate advanced queries:

SIEM queries:

secops-mcp.search_security_events(
    text="Advanced UDM query targeting specific behaviors",
    hours_back=TIME_FRAME_HOURS
)

BigQuery (for large-scale analysis):

bigquery.execute-query(query="Complex analytical query")

Step 4: Iterative Search & Analysis

Hunt Loop:

  1. Execute queries
  2. Analyze results for outliers, suspicious patterns
  3. Identify leads (suspicious hosts, users, processes, connections)
  4. Refine hypothesis based on findings
  5. Develop new, more targeted queries
  6. Repeat until exhausted or time limit reached

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.
