A toolkit for creating custom firmware and firmware patches for Phison 2251-03 (2303) USB controller chips, enabling BadUSB attacks via HID payload injection. It includes C# PC tools (DriveCom, EmbedPayload, Injector) for dumping and flashing drive firmware, plus 8051 firmware/patch code written in C.
Use cases
- dump firmware from a Phison USB flash drive
- flash custom firmware onto a Phison 2251-03 controller
- embed Rubber Ducky HID payloads into USB drive firmware
- build a BadUSB device from a supported flash drive
- patch existing Phison firmware with custom 8051 code
When to choose
- you need to research or demonstrate BadUSB attacks on Phison PS2251-03 drives
- you want to flash custom HID-payload firmware onto a supported USB drive
- you are doing USB firmware security research on 8051-based controllers
When to avoid
- your USB drive does not use a Phison 2251-03 controller or the tested firmware version 1.03.53
- you cannot risk permanently bricking the device
- you want a plug-and-play BadUSB tool rather than firmware-level research tooling
