About n0xa/m5stick-nemo
NEMO is an open-source firmware for M5Stack ESP32 devices (primarily M5 Stick C) that bundles a variety of high-tech pranks, digital self-defense utilities, and learning tools. It includes BadUSB Hunter to detect malicious USB peripherals, wireless attack detection (BLE, Deauth, PineAP), TV-B-Gone infrared control, AppleJuice iOS Bluetooth spam, WiFi SSID spam and a captive portal for credential harvesting. Other features include a WiFi scanner, digital clock with RTC, and EEPROM-backed settings. Designed for education and experimentation, NEMO demonstrates what a small development kit can achieve with curiosity and effort.
Key Features
BadUSB Hunter (Cardputer & ADV models) - detects HID devices, suspicious USB cables, and multi-interface BadUSB peripherals
Wireless Attack Detection: BLE Hunter, Deauth Hunter, and PineAP Hunter for situational awareness
TV-B-Gone port to shut off infrared-controlled TVs and projectors
AppleJuice iOS Bluetooth device pairing spam
Bluetooth notification spamming for SwiftPair (Windows) and Android
WiFi Spam - funny SSIDs, Rickroll, and random SSID generation
WiFi NEMO Portal - captive portal that captures email credentials to SD card
WiFi SSID Scanner - displays 2.4 GHz networks with cloning capability
User-adjustable 24-hour digital clock backed by M5 Stick RTC
EEPROM-backed settings for rotation, brightness, dimming, and portal SSID
