Spoofing MAC filters and Captive Portals on Public Wifi Networks

Spoofing MAC filters and Captive Portals on Public WiFi Networks

MAC filters are implemented on the networks to white-list particular devices and restrict access to the access point. At many public internet access points, a Captive Portal service is used to authenticate users. But what this service does to maintain that session is track MAC addresses of the authorised devices. As MAC filters are not inherently implemented in WiFi 802.11 standards, spoofing the captive portals through masked or spoofed MAC addresses is fairly easy. Here is how..

Deauthorising Everybody on a Wireless Network

De-authorising Everybody on a Wireless Network

Wireless networks have always been the easiest to use, yet they have been the most easily breachable networks. There is a wide array of utilities out there to help one do so. In this tutorial, we will be using Aircrack-ng suite of utilities to deauthorise selected nodes on a WiFi network. Kali Linux comes pre-installed with these utilities, so we would be following this tutorial on this OS. But these utilities are also available for Windows family of OSes, here.
