 🔐 How to Hack Wi-Fi Using ESP32

🧠 Disclaimer:

This guide is created only for educational and ethical hacking learning. Never attempt to hack or access any Wi-Fi network without proper authorization. Misuse of these techniques is illegal and punishable under law. The purpose of this blog is to teach how hackers exploit vulnerabilities — so we can build safer networks.




📘 What is ESP32?

The ESP32 is a low-cost, Wi-Fi and Bluetooth-enabled microcontroller used in:

  • IoT projects

  • Embedded systems

  • Ethical hacking education

Thanks to its built-in wireless capabilities and compact size, it is widely used in Wi-Fi testing and security learning projects.

⚡ What Can ESP32 Do for Wi-Fi Hacking Education?

1. 🔍 Scan Nearby Wi-Fi Networks

ESP32 can scan and list all nearby wireless networks. This helps students:

  • Learn how devices detect networks

  • Understand SSIDs, signal strength (RSSI), and encryption types

🧪 Sample Code (Wi-Fi Scanner):

#include "WiFi.h"

void setup() {
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);

Serial.println("Scanning...");
  int networks = WiFi.scanNetworks();
  for (int i = 0; i < networks; ++i) {
    Serial.print("SSID: ");
    Serial.println(WiFi.SSID(i));
  }
}

void loop() {}


2. 💣 Test Deauthentication Attacks (Legally)

Using special firmware like ESP32 Deauther or Marauder, ethical hackers can simulate deauth attacks, which: Send fake "disconnect" packets Temporarily kick devices off a Wi-Fi network

🧠 Educational Purpose:
This helps learners understand how Wi-Fi can be jammed and how to prevent it.

⚠️ Always test only on your own network or in lab environments.

3. 📍 Track Wi-Fi + GPS Location

Students can connect:

  • A GPS module

  • An OLED display

This setup can show:

  • Current GPS location

  • Nearby Wi-Fi network names

  • Signal strengths

🧠 Purpose: Helps learners visualize network range and location mapping.
