## What it does

The skill takes indicators from unstructured text: IPs, domains including hostnames, URLs, emails, CVEs, file hashes (md5, sha1, sha256) and MITRE techniques. It normalizes them and hunts in `fetch logs` and `fetch spans`. You get matched-observable evidence sets plus a threat-exposure score from 0 to 100.

It loads `dt-dql-essentials` first, because every hunt template depends on the DQL syntax defined there. Queries come from validated templates; only the IoC arrays and the time window are meant to change. Large indicator lists get chunked — 25 by default, 10 for long URLs, emails or hashes. Output is aggregated per entity rather than per record.

CVEs and MITRE techniques never go to logs or spans, since no field matches them there; they are routed to `dt-sec-insights`. Emails and file hashes are logs-only. Unanchored hunts default to `from:now()-30m`, and on a time-limit failure the skill retries at 15m then 5m on its own. If 5m also times out, the result is marked INCONCLUSIVE rather than no-match. Worth remembering: an empty answer inside a tight window does not mean you are clean.

## Requirements
- Works with: Dynatrace

## Install

### Claude Code (native platform)

```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-ioc-hunting -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/dt-sec-ioc-hunting/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/dt-sec-ioc-hunting/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-ioc-hunting -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/dt-sec-ioc-hunting/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-ioc-hunting -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/dt-sec-ioc-hunting/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Dynatrace/dynatrace-for-ai dt-sec-ioc-hunting
```

2. **Manually: put the files in place**
- File: `.github/skills/dt-sec-ioc-hunting/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-ioc-hunting -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Dynatrace/dynatrace-for-ai --path skills/dt-sec-ioc-hunting
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/dt-sec-ioc-hunting/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-ioc-hunting -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Dynatrace/dynatrace-for-ai/tree/HEAD/skills/dt-sec-ioc-hunting/SKILL.md

## When to use it
- pull indicators of compromise out of an advisory and normalize them
- check whether suspicious IPs and domains show up in logs and spans
- map CVEs from a report to vulnerabilities in the environment
- get a threat-exposure score on a 0 to 100 scale
- find secondary IPs in proxy and relay headers among matched records

## Example prompts
- check these indicators in my logs and traces
- extract IoCs from this advisory URL and hunt them in my environment
- search these hashes, domains and IPs in my environment

  tied to an IoC hunt (use dt-obs-logs); general span/trace analysis
  (use dt-obs-tracing); explaining DQL syntax (use dt-dql-essentials).

# IoC Hunting Skill

Hunt indicators of compromise (IoCs) across Dynatrace **logs** and **spans**,
and optionally correlate CVEs and attacker-IPs/MITRE techniques through
`security.events` (routed to **dt-sec-insights**). Produces matched-observable
evidence sets and an AI threat-exposure score (0–100%).

## Universal Best Practices

1. **Always load `dt-dql-essentials` first** — it provides DQL syntax, function
   reference, and query construction patterns required by all hunt templates.
2. **Ground every query in a template** — reference files contain validated DQL
   adapted from the Dynatrace Threat Exposure Analysis dashboard. Do not improvise
   hunt queries; modify only the IoC arrays and time window.
3. **Use indexed log prefiltering for broad hunts** — in log hunts, generate literal
   `matchesPhrase(content, "<ioc>")` clauses before using `contains` to populate
   matched-observable columns. Do not start unscoped log hunts with raw
   `iAny(contains(content, allObservables[]))`.
4. **Chunk large log IoC sets** — do not generate one DQL query with hundreds of
   `matchesPhrase` clauses. Split large IoC lists into smaller chunks (default 25
   IoCs; 10 for long URLs/emails/hashes or after a query-length failure), run each
   chunk with the same timeframe/scope, and aggregate results outside DQL. A no-match
