I need to plug a cctv style camera via usb on my computer in order to read what it recorded.

In general, how can I protect the computer I plug a usb device into, if I am worried the USB device might contain malicious code (e.g. malicious firmware from the manufacturer itself)?

Note that my question is different from this other one which refers only to usb drives, whereas mine relates to USB devices (camera). Also the context is different (home versus hospital).

  • @SmokeDispenser I think OPs Question is not a duplicate of my Question. I was refering to USB Storage and cleansing ob files on it whereas OPs Question referes to a USB Camera that is not mounted as a Storage Device

  • to be clear, the attack vector you want to protect yourself of is a possbly malicous firmeware of said usb camera (as it is not mounted as a storage divice? if not, please clarify where you suspect the malicious code

  • Hi Martin, my main concern is indeed of malicious firmware from the usb camera.

If you are really worried that there may be some malware on a removable device than your best bet is probably to run a live linux disk to check the device. This will give you the ability to access / scan any devices without putting your local hard disk at risk.
