NetCutter will present a command‑line interface that allows you to scan the local network, select a target device, and start or stop the ARP‑spoofing attack. Because the project is relatively young (3 commits at the time of writing), it may require testing on different Android devices and kernels. The author notes that Linux support is still incomplete and welcomes contributions.

It simultaneously sends forged ARP responses to the router, claiming your Android phone is the target device.
When Device A wants to communicate with the Router, it checks its local ARP cache to find the Router’s MAC address. Netcut Termux
Since the original NetCut APK is not designed to run natively inside Termux, we use open-source alternatives that replicate its functions and more. Below are the two most powerful and popular options.
Note that root/administrator privileges are required for ARP spoofing functionality, and GTK4 support on Termux may be limited.
The intersection of Netcut and Termux is therefore a powerful combination: it brings the network manipulation capabilities of Netcut into a lightweight, open‑source, mobile environment. This article explores how to use such tools on Termux, explains the underlying technology, discusses legal and ethical boundaries, and provides guidance on defending against these attacks. : Only use these tools on networks you
Termux is an advanced terminal emulator for Android devices that provides a Linux-like environment without requiring root access. It brings a powerful command-line interface to smartphones and tablets, allowing users to install and run hundreds of Linux packages, programming languages, and networking tools directly on their Android devices.

The combination of Termux with tools like arpspoof , bettercap , and nmap far exceeds anything the original Netcut offers. You get: When Device A wants to communicate with the
By default, the API runs on http://localhost:5000 .
The toolkit comes with a clear legal disclaimer emphasizing that it is “for educational and authorized testing purposes only,” and warns that “unauthorized access to computer systems is illegal and punishable by law”.

Use 192.168.1.0/24 and never publish real IPs or MAC addresses from live tests without consent.
) to perform ARP spoofing attacks, which can "cut" the internet connection for specific devices on the same network. Installation & Usage (Common Approach)
