B8 - Undetectable Wi-Fi Shell

Yago Fernández Hansen

For this masterclass, a script has been programmed using Python and Scapy library for generating a shell on a Linux system that will be accessible only through another computer that executes the same script. This has been achieved by using a secondary channel on Wi-Fi, based on the exchange of encapsulated and encrypted 802.11 frames.
Using two Wi-Fi adapters in monitor mode, one for the server and another for the client, any command can be executed on the server shell just by using the same script on the client and on the server side. By using a secondary channel, in addition of data encryption, we protect that shell from any unauthorized access, converting it into a very secure and original way to administrate the server wirelessly.
