Well that was an unexpected twist. Dammit Physics! I decided to put some regular black electrical tape over the camera to block it whilst keeping a neat finish. Turns out IR passes straight through electrical tape 😂 I did consider whether its because of the adjacent backlight and so I tried blocking that too, however most of the rooms I sit in have enough ambient IR to not matter. I'm considering something more "glass like" since that seems to reflect IR much better but the seems a pain. Anyone else have a better solution they've found? Its probably at the point for me that its "good to know but can't be bothered" but there's just so many interesting and unexpected outcomes I felt compelled to satisfy my curiosity and share. #Cyber #Security #Infosec #Lenovo #Privacy #Hacking

    @Slater450413@infosec.exchange You could try aluminium or copper tape, or use electrical tape to fix a small piece of aluminium foil. That should block any light short of gamma rays, I think.
