Python Access Point Scan (Scapy)

With Python, you can also evaluate beacons and probe responses. All you need is the Scapy library, and some Python code. I developed this Python script for my own access point analysis. If you like it, you can freely use it and further develop it. In addition, there is also a small bash script which helps you to set the monitor mode for the respective interface.

Objective

The aim of this tutorial is to analyse Wi-Fi access points with Python Scapy.
