Cyber Weapons Lab, Episode 164

Sometimes, you need an offline way of communication, such as after a natural disaster, during a protest demonstration, or where there is just no cellular or Wi-Fi networks to get you online. In this Cyber Weapons Lab, we’ll show ho to turn a low-cost ESP32 into a web server hosting an offline chatroom that anyone with a Wi-Fi card and a web browser can connect to anonymously.
