NetCut: WifiKill for PC – Disable Internet of other wifi users

Few months back, I shared an Android app called wifkill to kick other devices off a wifi network. Let’s do the same thing again, but this time with a windows PC. A small software utility called NetCut(popularly known as Wifikill for PC) does the same thing which the wifikill apk app does. The main problem with the wifikill app is its requirement of a rooted android phone. But no special requirement needed for NetCut. It can be installed and operated on any normal Windows 7 and windows 8/8.1 PC.


This post is solely for educational and learning purpose. This software should only be used on your Local wi-fi network. It is not meant to be used with public wi-fi networks. This software should not be misused and should not be used to play with any public wireless network security.

Before beginning the turorial, let’s take a look at some features of Netcut.

What NetCut can Do?

  • Netcut is a wireless network analyzer tool.
  •  You can find MAC addresses of all the devices connected to your Wireless LAN. You can find their brand name, IP address and even change their MAC address.
  • The most interesting part is you can Disable the Internet connectivity of any device connected to the wifi network.

Installing and operating NetCut (wifikill for PC):

1. First of all download the Netcut (only 2 MB in size) from the following link. Unpack the content of rar file to get the setup files.
Download Here –Netcut (Mediafire link)

2. Install the netcut as you install a normal software(with defaults). After completing the installation, it will begin the installation of winPcap(necessary). If not started, manually install the winPcap(included inside rar file) .

6. In order to cut the Internet connectivity of a device, select it from list and click on cutoff button. The blue icon for that device will turn into red showing that device has been lost its internet connectivity. If you want to restore the internet connectivity, simply select the device and click the Resume button.     netcut windows 7                                              netcut windows 8

7. Notice the checkbox protect my computer on top. Checking it will ensure that your device is not vulnerable to netcut attack (If some other user on the wireless LAN has Netcut installed).       
8. With this wireless network monitoring tool, you can secure your wireless network.
 Another main feature of netcut is that you can change the MAC address of any connected device. Highlight the device and click Change MAC button.
10. You will not be able to control the devices which have Anti- netcut (Netcut defender) installed and running.

How Netcut Works:

NetCut makes use of a ARP(Adress Resolution Protocol) Spoofing technique. The attacker associate the victm’s ip address with his own mac address, so that all the traffic which is meant for victom PC flow to Hacker’s system. As a result, the victim’s PC loose Internet Connectivity.Unfortunately, ARP is a stateless protocol. This means we continue to accept ARP replies and overwrite the old ones, even they have not expired yet. Worse, ARP does not define any authentication method to check whether the replies come from the trusted one.

    This netcut just work fine on windows xp and windows 7,
    it doesn't work with windows 8, 8.1, and 10.
    You can install on that version of windows, you can cut someboby through installed netcut on that windows, but the target still connect 😉
    trust me. it does'nt work in windows 8, 8.1, and 10.

    and netcut for android work fine, but if the target plays youtube, the target stiil connected to youtube, you can not cut this target using installed netcut on your android device.

    Why U mother fuckers build such kind of bloody apps…these apps are such annoying and must be no asshole can take away the right of others to use wifi in hostels…fuck off developer's

      Because people don’t bother turning off their torrents on limited bandwith internet access point, and drain all the bandwith leaving other users sturggling with their 12k.o/speed.
