# TGS-REP Roasting / Kerberoasting
Notes de sécurité Active Directory pour TGS-REP Roasting / Kerberoasting, couvrant l'énumération, Kerberos, les identifiants, l'abus des ACL, le mouvement latéral, le flux de travail d'exploitation et les étapes de validation.
### Principe
**Kerberoasting** consiste à interroger les tickets de service Kerberos pour des comptes ayant un **SPN**, puis à tenter de casser hors ligne la partie chiffrée du ticket.
Un **SPN**, ou **Nom de principal de service**, associe un service à un compte Active Directory.
Exemples de SPN :
{% code overflow="wrap" %}
```bash
HTTP/webserver.whoami.local
MSSQLSvc/sql01.whoami.local
CIFS/ws01.whoami.local
MailSrv/MS01.corp.local
```
{% endcode %}
### Objectif
L'objectif du Kerberoasting est de cibler les comptes de service.
Si le mot de passe du compte de service est faible, le ticket récupéré peut être cassé hors ligne.
### Vérifier les SPN d'un ordinateur
Avec PowerView :
{% code overflow="wrap" %}
```bash
Get-NetComputer -Identity WS01
```
{% endcode %}
Nous pouvons voir des SPN par défaut tels que :
{% code overflow="wrap" %}
```powershell
RestrictedKrbHost/WS01
HOST/WS01
RestrictedKrbHost/WS01.whoami.local
HOST/WS01.whoami.local
```
{% endcode %}

## 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/kerberos/tgs-rep-roasting-or-kerberoasting.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.
