ESP32-WiFi-Hash-Monster | WiFi Hash Purple Monster , store EAPOL

ESP32-WiFi-Hash-Monster is a C library typically used in Internet of Things (IoT), Arduino applications. ESP32-WiFi-Hash-Monster has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

WiFi Hash Purple Monster, store EAPOL & PMKID packets in an SD CARD using a M5STACK / ESP32 device. 90% of the code is based on the great PacketMonitor32 from   and the port to M5Stack from macsbug. It was a challenge to see if I could mimic the operation of pwnagotchi in an ESP32 SoC. When a wifi device connect to an AP with WPA2/PSK instead of sharing the wifi key they exchange 4 EAPOL messages, this method is known as the 4-way handshake, capturing these 4 packets is possible to guess the password using dictonary attacks or brute force attack, recentely there is a more efficent way to calculate the wifi key using just one PMKID packet. Purple Hash Monster capture all the EAPOL / PMKID packets on the SD Card for further analysis. Short press on first button will change enable incognito mode (Display and leds off) long press will enable the SD Card and all EAPOL / PMKID will be stored on the SD-Card. Short press on the second button will change the display backlight brighness, long press will change the LED bars brightness. Short press on the third button will change WiFi Channel, long press will enable Auto-Channel or Smart-Channel modes. Auto-Channel hop between channels 1,6 and after 15 seconds. Smart-Channel cover all the channels sequentially, but only hop if there is not new SSID, EAPOL or DEAUTHS after 15 seconds. When a deauth packet is detected left LED bar will became red and for every EAPOL / PMKID detected right LED bar will became green, also de Purple Hash Monster behaviour will change depending on the WiFi trafic and packets detected. Use Arduino IDE to compile it, tested with (ESP32 version 1.0.4) M5stack-fire.
