# Extraction de LSASS et SAM sous Windows

Notes de sécurité Active Directory pour l'extraction de LSASS et SAM sous Windows, couvrant l'énumération, Kerberos, les identifiants, l'abus des ACL, le mouvement latéral, le flux de travail d'exploitation et les étapes de validation.

### Exécution dans le laboratoire

Dans le laboratoire, nous ouvrons plusieurs sessions PowerShell :

* deux sessions avec un administrateur local ;
* une session avec un administrateur de domaine.

Ensuite, nous lançons l’outil depuis une session PowerShell d’administrateur local :

```bash
./mimikats.exe
```

### Afficher les informations de session

Dans l’outil :

```powershell
sekurlsa::logonpasswords
```

Cette commande affiche des informations relatives aux sessions d’authentification présentes en mémoire.

Selon le contexte, nous pouvons voir des informations telles que :

* utilisateurs connectés ;
* domaine ;
* type d’authentification ;
* des hachages ;
* tickets ou éléments liés à Kerberos ;
* sessions interactives ou réseau.

### Casser un hachage NTLM

Si un hachage NTLM est récupéré dans le laboratoire, il peut être testé avec John :

```bash
john --format=NT admin.hash
```

Cela permet d’illustrer le risque de mots de passe faibles ou réutilisés.

# 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/credentials/lsass-and-sam-dump-on-windows.md?ask=<question>&goal=<user_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.
