A simple tool to cut people's network with ARP spoofing, written in pure C++

NetCut ✂️

Introduction

A simple tool to ban people's Internet connection with ARP spoofing.

Note:

1. This tool is developed and tested on Linux platforms (Ubuntu 20.04, Arch Linux and alpine), currently it has no support for macOS and Windows.
2. This tool does not perform any advanced attack beyond ARP spoofing. So if your target is aware of the attack, he/she may be able to nullify the tool.
3. This tool is only effective against targets in the same network.

How to install

1. Clone the repository on github (https://github.com/cdes5804/NetCut)

2. cd into the directory and make.

   

How to use

1. After make, run the program with sudo bin/main. sudo is required for performing the attack.

2. After the program is started, it scans the network for available targets automatically.

3. Choose the targets by entering their numbers, separated by space if there are many. Easy as that.

   

4. Bam! Wait and see the people start complaining about the Internet.

   

5. To restore their Internet connections, just select them again.

   

netcut's Issues

No such file pistache/endpoint.h when running make.

traceback:

Two interfaces under the same subnet

The current design does not consider the case where the user has multiple interfaces under the same subnet or different subnets but with the same IPs. The behavior is to be tested and possibly fixed.

"make" error

mkdir -p bin/models
g++ src/models/scanner.cpp -c -o bin/models/scanner.o -Wall -Wextra -O2 -std=c++17 -I src/
make: g++: No such file or directory
make: *** [Makefile:17: bin/models/scanner.o] Error 127

problematic wait interval

Currently the wait interval is set to 3ms, which means if the target does not replay within 3ms, it is considered not in the network. This can cause some problems as the response may be late. But extending the interval will result in longer scanning time. Possible solution is to always listening with a thread and add targets as we receive response, instead of waiting for specific target to response.

scan_networks: Unable to get interface information.

help please?

zsh: segmentation fault sudo bin/main

When I put sudo bin/main It puts :

zsh: segmentation fault sudo bin/main

Backup plan when gateway is not found

When gateway is not found, fallback to the original plan of spoofing every other host.

192.168.1.1 Only available target

========================= Net Cut =========================
Select one or more targets by number, separated by space.
Or enter 'q' to quit, 'r' to refresh targets.
green: available targets, select to cut.
red: already cut targets, select to recover.

Targets: 

I can confirm that there are other users on the network.
