  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by gensecaihq on GitHub. Read the source before you install it.

Installation

Install the Identity Compromise AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/gensecaihq/Wazuh-Autopilot/tree/main/backend/app/skills/identity-compromise
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/gensecaihq/Wazuh-Autopilot.git /tmp/Wazuh-Autopilot
mkdir -p .claude/skills
cp -r /tmp/Wazuh-Autopilot/backend/app/skills/identity-compromise .claude/skills/identity-compromise
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Identity Compromise in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Identity Compromise on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Identity Compromise is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Identity Compromise Investigation

Accounts are the most common path to impact. Decide whether an account is compromised, how far it was used, and what containment is justified.

Key events and the Wazuh rules that surface them

Rule numbers are from the stock Wazuh 4.14 ruleset. Many Windows events are only alerted on when the channel is collected and not filtered. If there's no rule, search the raw event with search_security_events (field data.win.system.eventID). Load wazuh-windows-sysmon for Windows field paths.

Procedure

  1. List all auth events for the user over 7 days (search_security_events(query="<user>")), and aggregate by source IP and host (get_alerts_aggregated).
  2. Establish baseline: usual source IPs, hosts, hours, logon types.
  3. Test each hypothesis below; record which are supported.
  4. Determine scope: every host the account touched after the suspected compromise time.

Verdict

  • Compromised — success from attacker-controlled source, or malicious actions by the account. Confidence ≥ 0.8.
  • Targeted, not compromised — failures only, no success. Recommend blocking the source, not disabling the user.
  • Inconclusive — anomalies without malicious actions; recommend user verification.

Recommend disable_user (proposed by response-planner) only with evidence of successful malicious use. Service accounts and break-glass accounts: flag the business impact explicitly; prefer blocking the source or isolating the host first.

Output

  • add_entities (user as victim; source IPs as attacker; hosts touched).
  • link_mitre for supported techniques.
  • update_case severity/confidence.
  • add_finding titled Identity assessment: <user> with baseline, hypotheses table (supported / not supported + evidence), hosts in scope, verdict, recommended containment. standard_refs: NIST-800-61r3, CIS-v8.1:5 (Account Management), CIS-v8.1:6 (Access Control Management).

Frequently asked questions

What does the Identity Compromise AI skill do?

Investigate suspected account compromise — brute force followed by success, impossible travel, privilege escalation and lateral movement across Linux and Windows; use when a user account appears in suspicious authentication activity.

Why use Identity Compromise on TypingMind?

Because you install it once and use it with any model. Identity Compromise is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Identity Compromise in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/gensecaihq/Wazuh-Autopilot/tree/main/backend/app/skills/identity-compromise. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Identity Compromise?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Identity Compromise?

As many as you like. As long as a model supports skills, you can use Identity Compromise with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Identity Compromise AI skill free?

Yes. It is published on GitHub by gensecaihq under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
