![]() Finally, we add these information to the dataframe with the BSSID as the index. Scapy's Dot11Beacon class has the awesome network_stats() function that extracts some useful information from the network, such as the channel, rates, and encryption type. This callback makes sure that the sniffed packet has a beacon layer on it, if it is the case, then it will extract the BSSID, SSID (name of access point), signal, and some stats. #Wifi scanner linux how toRelated: How to Make a MAC Address Changer in Python Networks.loc = (ssid, dbm_signal, channel, crypto) If you're familiar with Scapy, then you know for sure that we are going to use the sniff() function, which takes the callback function that is executed whenever a packet is sniffed, let's implement this function: def callback(packet): So I've set the BSSID (MAC address of the access point) as the index of each row, as it is unique for every device. # set the index BSSID (MAC address of the AP) Next, we need to initialize an empty data frame that stores our networks: # initialize the networks dataframe that will contain all access points nearby Let's get started, open up a new Python file and import the necessary modules: from scapy.all import * Sudo iwconfig wlan0 mode monitor GET -10% OFF: Build 24 Ethical Hacking Scripts & Tools with Python EBook Writing the Code You can also use iwconfig itself to change your network card into monitor mode: sudo ifconfig wlan0 down Now you can check your interface name using iwconfig:Īs you can see, our interface is now in monitor mode and has the name "wlan0mon". #Wifi scanner linux installNow the code of this tutorial won't work if you do not enable monitor mode in your network interface, please install aircrack-ng (comes pre-installed on Kali) and run the following command: Note: This tutorial assumes you are using any Unix-based environment, it is also suggested you use Kali Linux.Īfter that, we gonna use pandas just for printing in a nice format (you can change that obviously): pip3 install pandas Or you can clone the current development version in Github: git clone To get started, you need to install Scapy, I have cloned the development version, you can also install it using pip: pip3 install scapy Related: How to Extract Saved WiFi Passwords in Python. If you're in this field for a while, you might have seen the airodump-ng utility that sniffs, captures, and decodes 802.11 frames to display nearby wireless networks in a nice format, in this tutorial, we will do a similar one. Have you ever wanted to build a tool to display nearby wireless networks along with their MAC address and some other useful information? Well, in this tutorial, we are going to build a Wi-Fi scanner using the Scapy library in Python. ![]()
