Netcut Kali Linux [patched]

. While originally a Windows-based application, its core functionality is a staple of security testing on Kali Linux netcut kali linux

At the core of NetCut's functionality is a technique known as ARP spoofing or ARP poisoning [2, 3]. The Address Resolution Protocol (ARP) is a fundamental networking protocol used to map dynamic Internet Protocol (IP) addresses to fixed physical Media Access Control (MAC) addresses on a local area network [2, 3]. Because ARP was designed without built-in authentication, devices automatically trust and accept ARP responses, even if they never sent a corresponding request. NetCut exploits this inherent trust. By flooding the network with forged ARP packets, NetCut convinces the target device that the attacker’s machine is the default gateway (router), and simultaneously convinces the router that the attacker’s machine is the target device [2, 3]. Once this link is established, NetCut can simply drop the packets instead of forwarding them, effectively cutting off the target's internet access, or it can limit the bandwidth allocated to that specific user [2]. To sniff/intercept (Target stays online):

Netcut sends a stream of spoofed ARP packets to the target device and the router. It tells the target that your computer is the router (Gateway). The target sends its internet traffic to you, but because you are not actually forwarding it (IP forwarding is disabled), the target loses internet connectivity. Once this link is established, NetCut can simply

On critical devices (like servers or your own PC), manually define the router's MAC address.
