Project Overview
Custom penetration testing and security assessment hardware built on ATmega32U4 microcontrollers for educational security research.
Problem Statement & Engineering Motivation
Demonstrating how Human Interface Device (HID) trust models in modern operating systems can be abused if physical access is unprotected.
Technical Architecture & Implementation
Programmed an ATmega32U4 micro-development board to identify as a standard USB keyboard, executing scripted diagnostic keystroke sequences within milliseconds of insertion.
Key Technical Features
- Hardware-level keystroke emulation bypassing standard software USB blocks
- Custom payload storage and execution timing controls
- Demonstration tool for educating organizations on physical port security
Technology & Component Stack
- ATmega32U4
- C++
- USB HID Protocol
- Hardware Security
Outcomes & Engineering Lessons Learned
- Physical port security policies and hardware-level USB whitelisting are critical components of enterprise security posture.
