# TGS-REP Roasting / Kerberoasting
### 原理
**Kerberoasting** 涉及查询具有一个 Kerberos 服务票证的账户 **SPN**，然后尝试离线破解票据的加密部分。
一个 **SPN**，或 **服务主体名称**，将服务与 Active Directory 帐户关联起来。
SPN 示例：
{% code overflow="wrap" %}
```bash
HTTP/webserver.whoami.local
MSSQLSvc/sql01.whoami.local
CIFS/ws01.whoami.local
MailSrv/MS01.corp.local
```
{% endcode %}
### 目标
Kerberoasting 的目标是针对服务帐户。
如果服务帐户密码较弱，恢复出的票据可能会被离线破解。
### 检查计算机的 SPN
使用 PowerView：
{% code overflow="wrap" %}
```bash
Get-NetComputer -Identity WS01
```
{% endcode %}
我们可以看到默认的 SPN，例如：
{% 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 dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hacking-notes.jord4n.pro/zh/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 optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
