Some old programs versions can be found here if someone needs them to test old exploits for instance.

It will be great to see a tumbler at the web interface to turn on and off the internet connection for the scan.

I suppose, you can turn on/off it in drakrun/main.py file using ifconfig vif manipulation, like sudo ifconfig vifX.0 down at the "process" function. Plus self.current_task.payload.get to obtain the tumbler state.
