# TGS-REP Roasting / Kerberoasting

### Принцип

**Kerberoasting** заключается в запросе сервисных билетов Kerberos для учетных записей с **SPN**, а затем в попытке взломать зашифрованную часть билета офлайн.

Один **SPN**или **Имя субъекта-службы**, связывает службу с учетной записью Active Directory.

Примеры SPN:

{% code overflow="wrap" %}

```bash
HTTP/webserver.whoami.local
MSSQLSvc/sql01.whoami.local
CIFS/ws01.whoami.local
MailSrv/MS01.corp.local
```

{% endcode %}

### Цель

Цель Kerberoasting — нацеливаться на учетные записи служб.

Если пароль учетной записи службы слабый, извлеченный билет можно взломать офлайн.

### Проверка SPN компьютера

С PowerView:

{% code overflow="wrap" %}

```bash
Get-NetComputer -Identity WS01
```

{% endcode %}

Мы можем видеть значения SPN по умолчанию, такие как:

{% code overflow="wrap" %}

```powershell
RestrictedKrbHost/WS01
HOST/WS01
RestrictedKrbHost/WS01.whoami.local
HOST/WS01.whoami.local
```

{% endcode %}

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hacking-notes.jord4n.pro/ru/active-directory/kerberos/tgs-rep-roasting-or-kerberoasting.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
