BadUSB
Flipper Zero badusb payload library
This project explores USB device emulation attacks—commonly called BadUSB—by demonstrating how commodity USB hardware can impersonate keyboards, network adapters, or storage devices to perform scripted actions on a host. It typically contains firmware examples, payloads, and explanations showing how a device presenting as a Human Interface Device (HID) can inject keystrokes, open shells, or orchestrate data exfiltration when plugged into a machine. The codebase is frequently intended for security research and defensive testing: defenders and red teams use it to validate endpoint controls, USB whitelisting, and user training. Due to the dual-use nature of such techniques, responsible repositories emphasize lab-only experiments, consent-based testing, and mitigations like disabling autorun, enforcing device policies, and using endpoint detection.
