National Grid displays a real-time frequency graph of the UK electricity supply.
A paragraph that invites us to view the spy planes over London with a degree of omnipotence. You can’t see them, but they watch you from above, watching what you type. A level of technology somewhat at odds with the blurry indistinct drone footage we’re used to seeing released to the media.
There may be a kernel of truth to the password story, though. Obviously if planes could capture the latent heat from keyboards through the roofs of London homes, that would be a damning inditement of the state of British home insulation.
If it were a computer password it would need to be pulled from a keyboard used only for authentication (or perhaps immediately after authentication) and no actual other typing? Keys that are only used for authentication - numbered keypads for door entries - are a different matter. For research into the effectiveness (spoiler: not massive) of using thermal cameras to recover key presses, see “Heat of the Moment: Characterizing the Efficacy of Thermal Camera-Based Attacks” from 2011.
There’s really no point making Terminator references beyond this point. Go home, we’re done here.
I’m all like, “hey, they’re doing a dark Black Mirror-esque remake of Postman Pat that taps into the public’s anxieties about the domestic use of drones and the destructive aspect of industrial automation on the sustainability of non-urban communities” and they’re all like “lol, don’t ever change Lee”.
