ARP spoofing and disconnecting devices from a network without explicit permission is in most jurisdictions. Use only on your own network or in authorized penetration testing labs.
NetCut is a powerful network tool in Kali Linux that can be used for various network-related tasks, such as network scanning, device discovery, and packet manipulation. Its command-line interface makes it easy to use and integrate into scripts and workflows. With its versatility and feature-rich interface, NetCut is a valuable tool for cybersecurity professionals and penetration testers.
Start Bettercap on your active network interface (e.g., eth0 for wired or wlan0 for Wi-Fi): sudo bettercap -iface wlan0 Use code with caution. netcut kali linux
This ensures that after you poison the ARP table, traffic still flows to the target, allowing you to intercept it (Man-in-the-Middle) or block it completely. echo 1 > /proc/sys/net/ipv4/ip_forward Open two terminals.
In the landscape of network security testing, the name "Netcut" often surfaces among beginners. Originally developed as a Windows-based utility, Netcut gained notoriety for its ability to perform ARP (Address Resolution Protocol) spoofing attacks, effectively disconnecting devices from a local network (a "deauthentication" attack at Layer 2) or intercepting their traffic. A common question among aspiring penetration testers is whether to use Netcut within the Kali Linux environment. The technical answer is nuanced: while you can run Netcut on Kali (via compatibility layers), doing so is architecturally redundant and often less powerful than using Kali's native toolset.
