# AS-REP Roasting с Wireshark
### Ручное наблюдение
В лаборатории мы можем захватить трафик с помощью Wireshark во время попытки аутентификации.
Мы особенно наблюдаем:
```bash
AS-REQ
AS-REP
```
В пакете Kerberos мы можем проанализировать:
```bash
padata
padata-value
шифр
salt
```
Эти значения можно использовать для восстановления хэша в формате, совместимом с John или Hashcat.
### Формат Hashcat 19900
Для некоторых случаев, связанных с предаутентификацией 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 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/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 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.
