DNS Spoofer

This Python script allows you to perform DNS spoofing by intercepting DNS packets and modifying their responses. It utilizes the netfilterqueue library to capture and manipulate network traffic

Prerequisites

Before running the script, make sure you have the following prerequisites installed:

• Python 3.xx
• scapy library
• netfilterqueue library You can install the required libraries using pip:

$ pip install scapy netfilterqueue

or if netfilterqueue not installed properly, try this:

$ sudo pip3 install --upgrade -U git+https://github.com/kti/python-netfilterqueue

Usage

$ python3 dns_spoofer.py --host <IP_ADDRESS> --queue-num <QUEUE_NUMBER> --domain <DOMAIN_NAME>

Options

• --host: Specify the IP address for your fake DNS server.
• --queue-num: Specify the queue number to trap the sniffed packets.
• --domain: Specify the domain name that you want to spoof its IP.

Example usage:

• Run your script and provide the queue-num to the one that you specified before in the command above:

$ python3 dns_spoofer.py --host 192.168.152.157 --queue-num 7 --domain www.bing.com
