Re: Another 007 scheme ?

I'd venture there are a fair few air-gapped systems out there that aren't going the whole hog on anti-TEMPEST.

Iran published photographs from the supposedly air-gapped Natanz facility computer room with dozens of people milling around and the place looked.. highly ordinary. It's not implausible that a short video clip published in similar circumstances could leak a passhrase or other short string from a screen which was otherwise free of sensitive information.
