WiFi Deauther

Network deauthentication tool, deauth, beacon and probe attacks driven from a compatible WiFi card. Built for authorized security testing.

problem

The problem

Understanding 802.11 management-frame attacks is foundational to wireless security. The only way to really learn how deauth/beacon/probe attacks work, and how to defend against them, is to implement them in a lab.

approach

How I approached it

  • Implemented deauth, beacon and probe frame operations against a WiFi card in monitor mode.
  • Built for hands-on study of 802.11 management-frame weaknesses in an authorized lab context.
