I created a small bash script called Nethole that uses ARP spoofing to break WPA3 connections—not by deauthing or capturing handshakes, but by silently killing connectivity.

Since WPA3 uses Management Frame Protection, tools like aircrack-ng don’t work well for attacks like deauth or handshake capture.

Instead, this tool sets up a MITM using arpspoof, then disables IP forwarding to cause infinite buffering on the victim’s device. They appear connected to Wi-Fi, but get no usable internet. It’s a “quiet” denial of service.

Tested it on Windows 10/11 and iPads (works), Xiaomi phones (resist it using ARP table hardening).

Here’s the GitHub repo: github.com/yourusername/nethole

I'd love feedback on whether this approach is already documented or if it might be useful for further exploration into WPA3 behavior.
