usbliter8 is a low-level security research project focused on a tethered SecureROM exploit for Apple A12, S4/S5, and A13 SoCs. It targets a USB controller bug that requires specialized microcontroller hardware rather than a normal Mac or PC USBstack. The repository includes firmware source code, board support files, shellcode directories, USB handling code, logging helpers, and a Python control tool. It is intended for advanced researchers who understand DFU behavior, embedded development, bootrom analysis, and the risks of hardware-level experimentation. ...
OpenSK is an open-source implementation for security keys
OpenSK is an open-source implementation of FIDO2 (WebAuthn + CTAP) security keys, written in Rust and designed to run on affordable microcontroller boards. It provides the full authenticator stack—USB/NFC transport, CTAP protocol handling, credential management, and cryptographic operations—so you can build and audit your own hardware token. The project emphasizes defense-in-depth: memory-safe Rust, hardened crypto, isolation via an embedded OS, and explicit user presence/verification flows. Developers can flash reference hardware, customize UX (LEDs, buttons, PIN), and experiment with extensions while staying interoperable with major browsers and platforms. ...
lpcusb is a USB core stack for the built-in USB device of LPC214x microcontrollers. It handles the hardware interface and USB enumeration/configuration. Included are usage examples like USB joystick HID, USB virtual COM port and USB mass storage on SD-ca
