Cheap SpeedLink Reflect LED Webcam

Creative Labs Live! Cam Sync HD Model VFO770

  • RTS5822 with PM25LD512 SPI Flash (64 KiB)
  • http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PNid=30&PFid=43&Level=4&Conn=3&ProdID=346
    The RTS5822 supports an internal MCU program ROM, external NOR-Flash interface, and external Serial-Flash interface. With the external Serial-Flash interface, the internal program ROM can be fully replaced and the control firmware can be easily accessed via the USB link.
  • Chip can be used with internal ROM only
  • Hacking the firmware probably allows disabling the recording LED (but this may also be possible by hacking the driver only)
  • We could dump the flash contents to check the firmware
  • Particular webcam has an SPI flash
    => most likely vulnerable.
