# WF-Bind Shell

Use this page when you already have code execution and the target can expose a listening port.

### Quick loop

1. Pick a port.
2. Start the bind shell.
3. Connect to the port.
4. Connect to the shell.
5. Decide whether to keep using it.

{% stepper %}
{% step %}

### Pick a reachable port

With a bind shell, the target opens a listening port.

In the example, the target listens on `0.0.0.0:1234`.
{% endstep %}

{% step %}

### Start the bind shell

Choose a bind shell command that fits the target OS and available tools.

The goal is simple:

* make the target listen
* expose a shell on that port
* connect to it from your machine
  {% endstep %}

{% step %}

### Connect to the port

After the target starts listening, connect to that port with `netcat`.
{% endstep %}

{% step %}

### Connect to the shell

Use `netcat` to connect.

```bash
nc -nv <TARGET_IP> 1234
```

If the shell responds, you have direct access to the target shell.
{% endstep %}

{% step %}

### Decide whether to keep using it

Bind shells can be convenient when they stay running.

If your connection drops, you may reconnect without rerunning the exploit.

If the process stops or the target reboots, you still lose access.
{% endstep %}
{% endstepper %}

### Fast decision rules

* If inbound firewall rules block the port, use a reverse shell instead.
* If the bind shell stays running, reconnect instead of rerunning the exploit.
* If access is unstable, use the bind shell only as a short bridge.

# 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 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://capcap-1.gitbook.io/capcap/readme/ctf-modules/getting-started_mod-2/wf-bind-shell.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.
