Forces all clients off a specific BSSID (router). This is the classic “Wi-Fi kick” used in WPA handshake captures.

The APT version may lag behind the developer’s latest commits. If you need experimental features or bug fixes, compile from source.
Step 1: Install build dependencies
sudo apt install git build-essential libpcap-dev libnl-3-dev libnl-genl-3-dev -y
Step 2: Clone the official repository
The most active fork (since the original was abandoned) is from xEless or aircrack-ng archive. Use: mdk3 install kali linux
git clone https://github.com/aircrack-ng/mdk3.git
cd mdk3
Step 3: Compile the binary
make
If make fails, check that all dependencies are installed. Common errors involve missing libnl headers.
Step 4: Install the binary system-wide
sudo make install
This copies mdk3 to /usr/local/bin/, making it globally accessible.
Step 5: Test
mdk3 --version
Installing MDK3 on Kali Linux is a straightforward process facilitated by the APT package manager. However, successful operation relies heavily on correct wireless hardware configuration—specifically enabling Monitor Mode and killing interfering processes. Users requiring the specific legacy binary should utilize the compilation method outlined in Section 4. Forces all clients off a specific BSSID (router)
Disclaimer: This paper is for educational and authorized security auditing purposes only. Using MDK3 against networks without express permission is illegal in most jurisdictions.
To install on Kali Linux (2024–2025 versions), you can use the standard package manager. While often pre-installed in the full Kali Linux Metapackages , it can be manually added via the terminal. Kali Linux 1. Standard Installation to install the tool and its required dependencies ( aircrack-ng Kali Linux Update your repositories sudo apt update Install MDK3 sudo apt install mdk3 Verify installation mdk3 --help Kali Linux 2. Manual Source Installation (Alternative)
If you require a specific modified version or have issues with the repository, you can build it from source using the Official MDK3 GitLab Clone the repository git clone https://gitlab.com Navigate and compile cd mdk3 && make sudo make install 3. Usage & Modes The APT version may lag behind the developer’s
MDK3 is a proof-of-concept tool used to exploit IEEE 802.11 protocol weaknesses. Before running it, you must put your wireless interface into monitor mode (e.g., using airmon-ng start wlan0 Kali Linux Command Example Description Beacon Flood mdk3 wlan0mon b Floods the area with fake Access Points. mdk3 wlan0mon a -a [MAC] Overwhelms an AP with authentication requests to freeze it.
