# TGS-REP Roasting / Kerberoasting
TGS-REP Roasting / 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
**Kerberoasting** …があるアカウントに対して Kerberos サービス チケットを照会し、 **SPN**、その後チケットの暗号化された部分をオフラインで解読しようとします。
1つの **SPN**や **サービス プリンシパル名**は、サービスを Active Directory アカウントに関連付けます。
SPN の例:
{% code overflow="wrap" %}
```bash
HTTP/webserver.whoami.local
MSSQLSvc/sql01.whoami.local
CIFS/ws01.whoami.local
MailSrv/MS01.corp.local
```
{% endcode %}
### 目的
Kerberoasting の目的は、サービス アカウントを狙うことです。
サービス アカウントのパスワードが弱い場合、回収したチケットはオフラインで解析される可能性があります。
### コンピューターの SPN を確認する
PowerView を使用:
{% code overflow="wrap" %}
```bash
Get-NetComputer -Identity WS01
```
{% endcode %}
次のような既定の SPN が見られます:
{% code overflow="wrap" %}
```powershell
RestrictedKrbHost/WS01
HOST/WS01
RestrictedKrbHost/WS01.whoami.local
HOST/WS01.whoami.local
```
{% endcode %}

## 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/tgs-rep-roasting-or-kerberoasting.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.
