WiFi is almost everywhere. Wherever you go there are WiFi packets emitted by smartphones, tablets, computers, access-points, etc. All WiFi packets “flying” around are divided into four main groups (802.11 Frame Types) – management, data, control and extension. In this article we will take care of capturing some interesting subtype packets of management group (Beacon … Read more
The common method of making a packet sniffer in User-Space is to use low-level operations on RAW sockets. But, instead of that, you can just use a powerful Python library – Scapy (see documentation), which exposes a user-friendly high level API. So, it hides all unfortunately low-level abstraction which we don’t really like in Python. … Read more
This experimental project shows how to build a simple and inexpensive WiFi packet analyzer (also known as a WiFi sniffer). The heart of this project is WiFi module of ESP32 which is able to work in a promiscusous mode. It means that this clever chip allows IEEE802.11 network packets capturing for further analyzing. Because WiFi … Read more
