DNS tunneling The idea of this technique is to use the DNS protocol to route all the traffic, just like a VPN! Of course this method will make your connection slower but will allow you to bypass certain systems like network filters or captive portals. Obviously, you could use this to exfiltrate data too. The reason why this works is that normally when captive portals or firewalls rules are setup, the administrators block all TCP and UDP connections when certain rule is met but they forget about checking DNS queries.
Attacking Wi-Fi networks with Aircrack-ng Before starting, remember that performing any of the attacks explained in this post to networks without previous consent is illegal, this post information is for educational purposes only. Introduction Wi-Fi uses management frames (datagrams are called frames in this context) and data frames. Only data frames are encrypted and injecting them into the network will require a previous association with the AP. This is not necessary for management frames or if we send data frames spoofing some of the clients MAC addresses.
MAGI project The idea I have been thinking about the idea of building a cluster made of Raspberrys and update my home infrastructure a bit. Right now, I use a Raspberry Pi 4 B as a little server to run Pi Hole, personal projects, Plex… and also as a NAS. All this sevices are run using Docker containers because I love Docker and the management is easier that way, allowing me to recover from a failure really quick.
