    Hello,

    I am a newbie here and am in need of some assistance. While doing business with a client, I had to plug his USB into my computer to transfer some footage. I'm not sure if he knew, but I had my OS set to display all "hidden" files. This is when I saw 3 "hidden" files on his usb; an "EFI" , a "live" and a "install". I transfered the files from his USB over to my computer and have begun inspecting them.

    I understand that they may be some sort of Linkux bootable, with possibly Clonezilla, and some other stuff that I am unaware of.

    I could use some help analyzing the folders to determine what these folders are actually doing and whether or not their is some mal-intent on my clients side. I am slightly suspect that he may be trying to snoop my hard drive.

    Those are leftovers from a Linux LiveCD, if there aren't any executables for your OS then it's probably just leftovers, but I can't tell you with 100% certainty without inspecting those files but you can always run AV through them. Most advanced USB hacking these days are in the firmware which can't been seen on any OS.

    Personally I wouldn't stick any foreign USB into my main computers.

    I did some looking and I didn't notice any executables. And can you elaborate on what you mean by AV? I am unfamiliar with the acronym. As for the firmware, that's a bit outside my scope. I will definitely be doing more research on that topic.
    But for now I agree with you, I won't be using any more foreign USBs on my computer. Thanks for the help biggreyhat.

    AV = anti virus
