I am won...

It is as if the payloads are not loaded, or the XSS validator is not wor...

  • Binding burp to a low port

    I am trying to do some invisible proxying through burp, but this requires binding burp's proxy to ports 80/443 which requires root privileges. However, if I run burp as root, it asks for another license. I am wondering if there's a way to bind to low ports without having to burn a license.
