# AS-REP Roasting с Wireshark
Заметки по безопасности Active Directory для AS-REP Roasting с Wireshark, охватывающие перечисление, Kerberos, учётные данные, злоупотребление ACL, боковое перемещение, рабочий процесс эксплуатации и шаги проверки.
### Ручное наблюдение
В лаборатории мы можем захватить трафик с помощью Wireshark во время попытки аутентификации.
В частности, мы наблюдаем:
```bash
AS-REQ
AS-REP
```
В пакете Kerberos мы можем проанализировать:
```bash
padata
padata-value
шифр
соль
```
Эти значения можно использовать, чтобы восстановить хэш в формате, совместимом с John или Hashcat.
### Формат Hashcat 19900
Для некоторых случаев, связанных с предварительной аутентификацией Kerberos, Hashcat может использовать режим:
```
19900
```
{% embed url="" %}
Пример структуры:
```
$krb5pa$18$user$DOMAIN$SALT$CIPHER
```
Пример, адаптированный к лаборатории:
{% code overflow="wrap" %}
```bash
$krb5pa$18$Administrador$WHOAMI.LOCAL$WIN-D4TRD7S7IHPAdministrador$96c289009b05181bfd32062962740b1b1ce5f74eb12e0266cde74e81094661addab08c0c1a178882c91a0ed89ae4e0e68d2820b9cce69770
```
{% endcode %}
Затем мы можем запустить John:
{% code overflow="wrap" %}
```bash
john --wordlist=passwords.txt hash
```
{% 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/ru/active-directory/kerberos/as-rep-roasting-with-wireshark.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.
