Auth-bypass-tool-v6 Libusb -
During testing on a popular "encrypted USB drive" with a PIN pad, auth-bypass-tool-v6 was able to unlock the drive without any PIN after 2.3 seconds. The drive used a Cypress FX2LP microcontroller, and the tool sent a malformed SET_FEATURE request that the firmware did not validate. The device responded with a configuration descriptor that marked the mass storage interface as "already unlocked."
