Proxy extension broken

[Phasip]

Summary

Beef has a proxy extension which runs a HTTP proxy on port 6789 which is supposed to tunnel traffic through a zombie. (Ref https://github.com/beefproject/beef/wiki/Tunneling )

The proxy extension on port 6789 has been reported broken in multiple issues, however the issues have been closed.

#3029
#2973
#2679
#2567

The issue is related to how the proxy extension attempts to read data from an SSLSocket before a handshake has been made.

How to Reproduce

Launch beef on localhost port 3000, hook a browser on localhost (tested on firefox linux), right click browser and select "Use as proxy" now run: http_proxy=http://localhost:6789 curl http://localhost:3000/

Errror

Thank you for reporting this issue. The proxy extension has been a recurring topic, and we acknowledge the challenges with its current implementation, especially with SSLSocket handling. However, due to bandwidth constraints, addressing this fix is currently a low priority.

Contributions or pull requests addressing this issue are welcome and appreciated in the meantime.

Thanks for understanding
