Sharing an Internet connection via wireless or even through cable is very common because a cheap home based router already comes with these features which are easy to setup. An annoying problem that people who are connected to the network can face is when one of the users is constantly using all the available bandwidth by downloading using BitTorrent, leaving practically nothing for other users. If everyone shares the Internet bill equally, obviously it is unfair for one person to hog it.
There are a few ways to solve this problem. The first method is of course to talk to the person and get them to adjust their BitTorrent program so that it doesn’t aggressively use up all the connection and stress out the router. If they ignore your suggestion, try to check if the router is able to block P2P connections or to specific websites.
If your router is very basic and not capable of blocking certain types of connections such as P2P that are used by BitTorrent, there are some programs that can forcefully cut off a person’s Internet connection when they are connected in the same network through ARP spoofing. Abusing these programs is unethical and can get you into trouble, so use it wisely and at your own risk.

1. NetcutNetcut is a well known Windows program that can cut off a person’s connection when connected in the same network. It is as easy as downloading and installing netcut, running the program, selecting a computer from the list and clicking a button. It takes merely a few seconds for the attack to take effect. Do take note that Netcut must be manually run as administrator because the program does not automatically invoke the UAC dialog or else you’ll get the error “Unable to Manage ARP Cache 4 please RunAs administrator”.
Other than using Netcut to cut off a hosts Internet connection, it can also be used to protect the computer that is running the program against such attack by ticking the “Protect My Computer” checkbox.
The latest version of NetCut is 2.1.4 which was released in 2011 and it comes with an older version of WinPcap 4.1.2 that does not support Windows 8 and Server 2012. If you plan to run NetCut from Windows 8 and above, you will need to manually download the latest version of WinPcap from the official website.
Netcut automatically runs at Windows startup through a service and can be disabled from the program options. However, the service is not removed when you uninstall Netcut and it takes up unnecessary memory usage. To disable Netcut services, press WIN+R to bring up the Run dialog box and type services.msc followed by hitting the Enter key. Double click on “Arp Intelligent Protection Service” from the list, click on the drop down menu for startup type and select “Disabled”. Then click the “Stop” button and finally the OK button to apply the changes.

2. Tuxcut
Tuxcut is similar to what Netcut does except it is made to run on Linux operating system. It is considered safer to run Tuxcut on a live Linux operating system from a Virtual Machine such as VirtualBox because there is no trace of installing and running such programs on the computer. Here is a guide on how to run Tuxcut from Lubuntu in VirtualBox.
1. Download Lubuntu
2. Download VirtualBox and install.
Best free invoice software for mac 2017. 3. Run VirtualBox and click the New button.
4. Type Lubuntu for the name and click Next.
5. Make sure that the memory size is at least 512MB, then click Next.
6. Select “Do not add a virtual hard drive” and click Create. Click the Continue button to close the warning popup.
7. Select Lubuntu from the list and click the Settings button.
8. Click on Storage, click on Empty for “Controller: IDE”, click on the CD icon and select “Choose a virtual CD/DVD disk file“.
9. Browse for the Lubuntu ISO file that you’ve downloaded and click OK.
10. Click on Settings again and go to Network. You should see that the adapter 1 is enabled and attached to NAT. Click on NAT and select “Bridged Adapter“. Make sure that an active adapter is selected. For example, if you’re connecting to a network via wireless, make sure that the wireless adapter is selected, not the wired ethernet adapter. Click OK to save the changes. Do not use NAT because it won’t detect other computers in the network.
11. Click the Start button to boot up Lubuntu in VirtualBox.
12. Select “Try Lubuntu without installing” and hit Enter.
13. After booting up Lubuntu, click the menu button located at the bottom left, go to Internet and select “Firefox Web Browser”.
14. Visit the following URL https://bitbucket.org/a_atalla/tuxcut/downloads and download the latest version of TuxCut in .deb format. Select the option “Open with GDebi Package Installer” and click OK.
15. Click the Install Package button.
16. After finished installing TuxCut and its dependencies, click the menu, select Run, type tuxcut and click OK.
17. Select the eth0 interface and click OK.
18. Do take note that when the “Protection Mode” is enabled, the available computers on the network will not be shown in TuxCut. If you uncheck “Protection Mode” and click the “Refresh” button, the computers will start showing up. To cut off a computer’s Internet connection, select the computer from the list and click the Cut button.
The “Protection Mode” only protects the guest operating system that is running Lubuntu, but not the host computer that is running Windows. When you shut down or restart Lubuntu, TuxCut will have to be redownloaded and reinstalled because it only runs from memory.
Additional Notes: It is never a good idea to use these type of programs to attack or protect a computer because it degrades the network’s performance. Either action from the program will cause the computer to send a massive amount of continuous packets to the router or gateway. In the end it is a no-win situation for everyone.

Replyhi. my brother who is always obsessed with me has a spy cam on his bedroom window directed to my front door. It’s humiliating but the police won’t do anything. His camera works only through wifi. I want to cut it from our Network since he uses same wifi as I do in this house. But this netcut only works with credit card. is there another way? I’m unsure to give my credit card to another country. I’m in USA.
ReplyIt does not affect anything. I off the connection one of the IP connected on my network. But still it has an internet access. Please help
ReplyWhen i try to cut other people network. My own pc get disconnected from my wifi… Although i dont cut my network from netcut help please
Replypost thank you for the beautiful share with us, respect
ReplyI found this tool to be interesting. Cheers Raymond. As always, you are giving your subscribers good tips. :)
ReplyBTW, this tool work of protocol level. So it’s can cut off any network devices that use ARP
ReplyA simple way to detect Netcut is to open command console and type “arp -a”. If there is more than one gateway, some body is using Netcut, or worse: spoofing your network.
ReplyOh, and it works on Xbox 360 and Playstations too :).
ReplyThank you, I downloaded it and it works great :). It’s funny to annoy other people in my network xD. Best music composition software.
ReplyThanks,downloaded.
ReplyYa, it works like a charm.

ReplyHa ha…, NetCut
i always use this tool.
In the school, free hotspot in a supermarket and everywhere, if i can connect my laptop.
NetCut is very usefull.
You can connect to a LAN Network, and if you want only you can connect to internet through LAN Network use this tool!
Some antivirus detect this software as a malware, but its up to you.
This software is clean (in my opinion) so try this software.
Not everybody know about this tool. They don’t know if their PC is not connected in Network cause this software, and don’t know to resolve that problem.
If you are sacrifice cause this tool, use Anti-NetCut.search it on google!.

NetCut is a Denial of Service type of tool that runs on Windows and is capable of cutting off a person’s internet connectivity when both are connected in the same local area network. Basically the ARP protocol is used to translate IP addresses to MAC addresses and NetCut exploits the weakness in the stateless ARP protocol due to the lack of authentication.
NetCut is very easy to use and can be used by anyone. Simply run the tool and it will detect all the connected devices in the same local area network. You can then select any target from the list followed by clicking the “Cut off” button, and within seconds the target will lose its internet connection. The affected target will have no idea what’s happened even if he/she has a firewall program installed.
Due to the way NetCut works, no firewall is able to prevent nor even detect the attack. In fact setting up static ARP entries like most other websites suggested will not protect you against NetCut attacks because NetCut directly attacks the gateway and not the user. Here is an investigation on how NetCut works and also the method to protect against the DoS attack.
As we’ve mentioned earlier, none of the firewall software such as ZoneAlarm, Comodo, Outpost, GlassWire, SpyShelter, Privatefirewall, and etc is able to detect NetCut attack. However you can use XArp, which is a freeware tool that can detect ARP spoofing. By installing XArp and running it, you will be instantly notified when it detects an ARP spoofing attack including the attack from NetCut. The screenshot below shows a running XArp without attacks. Take note of the MAC address 00-21-5d-41-16-5a circled in red which is associated with the IP 192.168.2.8.When NetCut starts attacking the IP 192.168.2.8 in an attempt to cut off the Internet connection, XArp immediately detects it and shows an alert popup with a few different messages. The most important message would be the one that reports that the MAC address for the IP 192.168.2.8 has been changed from 00-21-5d-41-16-5a to 03-27-75-49-18-73.
If you launch the XArp program from the notification tray icon, you will see that the MAC address for the IP 192.168.2.8 has been changed to 03-27-75-49-18-73 which is obviously wrong.
This means that NetCut sends a spoofed packet to inform the gateway that the IP 192.168.2.8 is associated with an incorrect MAC address. Since the IP 192.168.2.8 isn’t mapped to the correct MAC address, the Internet connection breaks as well. Even a packet sniffer such as Wireshark confirms that spoofed packets are sent to the gateway with a wrong MAC address mapped to the IP 192.168.2.8.
When NetCut is actively attacking a target on the network, it will continuously send spoofed packets to the gateway so that there is no chance for the gateway to obtain the correct dynamic ARP table. Here we have 5 possible ways of protecting against NetCut attacks.
1. Static ARP Table in Router
Since NetCut sends spoofed packets to the router to mess with the dynamic ARP table, you can solve this problem by setting up a static ARP table in the router. Implementing static ARP routing will protect everyone that is connected to the network. However this is not really a solution for everyone because a lot of basic home based routers don’t support static ARP table and it doesn’t make sense to implement this on a public WiFi. Doing this on a large corporate network also requires a lot of manpower maintaining the IP to MAC address mappings.
2. NetCut
Ironically, the NetCut program that is used to cut off a person’s Internet connection has an option to protect against the attack. Simply make sure that the “Protect My Computer” checkbox is ticked and this will ensure that your IP address is mapped to the correct MAC address.
Basically NetCut protects against its own attack by constantly sending packets to the gateway informing the router the correct mapping of the IP to MAC address. The router will be easily flooded with packets when NetCut is being used to attack and protect.

3. NetCut Defender
Epson workforce 4630 mac scanner app. If you’re not comfortable in having an attack program such as NetCut installed and running on your computer due to legal concerns, the author of NetCut also created a protection program called NetCut Defender. Basically it does the same thing as the “Protect My Computer” option found in NetCut except without the ability to cut off a person’s connection.
Nowhere on the official NetCut Defender’s website does it mention that it costs $9.99. You will start getting nagging popups to purchase the program after a couple of hours of usage. We cannot confirm the trial usage of NetCut Defender as we have not tested it extensively but what we can confirm is that it can surely keep you safe against NetCut attacks.
Download NetCut Defender
4. Outpost Firewall Pro
When NetCut is launched, it will automatically run an ARP broadcast sweep to detect all connected devices on the network. For example, if the computer running NetCut is connected to a network 192.168.2.1 gateway, it will perform an ARP sweep from 192.168.2.1 to 192.168.2.255. Unlike ICMP ping that can be easily blocked, ARP requests are normally responded and not blocked. When a device responds to the ARP request made by NetCut, the device is added to the list that can be attacked. Outpost Firewall Pro has an option to block ARP scan.
Go to Settings > Advanced settings > Attack Detection > click the Customize button > select “Block host when it enumerates other computers on LAN” and click OK to close the Attack Detection window followed by clicking OK to save the Settings.
Enabling this option will prevent your computer from being listed in NetCut. The attacker will most likely attack another computer instead of yours. Outpost Firewall Pro is a shareware that cost $29.95 for a 1 year subscription on a single license.
Download Outpost Firewall Pro
5. ESET Smart Security
https://migreat202.weebly.com/why-isnt-googleapp-showing-up-in-my-mac.html. ESET Smart Security is one of the few internet security applications that can be configured to disallow responses to an ARP request. By doing this, NetCut won’t be able to find your computer during an ARP sweep when the program is launched or when the “Refresh Net” button is clicked. To configure ESET Smart Security to block an ARP scan, open the program, go to Setup and click on Network. Click Advanced Personal firewall setup that is located at the bottom.
Expand Network > Personal firewall and select IDS and advanced options. Uncheck “Allow response to ARP requests from outside the Trusted zone” and click OK.
For this setting to take effect, you need to select the “Public network” as the desired protection mode of your computer in the network. Normally this option would show up when you are connected to a new network. To check the settings, at the Network protection setup, click on “Change the protection mode of your computer in the network“.
Select Public network option and click OK.
The NetCut program won’t be able to find your computer on the network, thus keeping you safe from being attacked.

Thank you. Very helpful.
ReplyAha, this is useful. I noted that I already did a lot of the protection as I have an annoying router, BUT it happens to support some more advanced protection. Or so I THINK, ahahaha (until I get into more advanced pen testing to VERIFY somewhat).
Good luck.
Look into open source routers and the arptables package that should be possible to run on them, that kind of thing… Again, I’m not expert.
