  • Western manufacturing tends to be much more automation heavy. Chinese manufactures don’t bother with buying a $100k machine that can make a car part when they can just hire 10 guys at $10k/yr to make that same part with a $50 drill press and some hand files.

    It’s not that it all strictly balances out, but if we actually gave a shit we could potentially be cost competitive for a lot of price brackets, especially given the costs to move whole ass cars across the Pacific.

    Bear in mind these sub $10k Chinese EVs are not something US consumers would really be interested in buying, they are basically tiny car shaped golf carts with extremely minimalist feature sets. Think ‘no audio system at’ all type interiors.




  • If you absolutely have to hand over your phone, turn it off completely, like hold the power button and then tap the off icon. That will dump any keys out of RAM, which is why it always requires the full password to unlock when you turn it back on. Both in terms of how your phone works and the leaks we’ve seen, the cracking tools the police have are overall significantly less likely to be successful when used on a phone that’s been turned off and not unlocked since.

    Also, IIRC iphones have a feature where they will dump at least some of the system keys from RAM if you push the lock button five times. I’d still trust fully off more but that’s easier to do covertly.









  • Yeah, I’d agree with that.

    The point I was making was for people who thought this was cellphone cameras and that it would somehow work even if the camera wasn’t actively running.

    As far as war driving with an sdr you’d probably occasionally find something interesting, but the vast majority would be cameras just pointed back out at the street. I think you’d mostly see stuff where if you wanted to spy it would make more sense to hide your own camera because it’s already public.

    All that said, I would lose my shit if Hollywood did something believable for once and used this for a heist movie.





  • I work on this stuff, short answer, no, it’s not possible. This is just yet another overly complicated tempest attack. Especially with phones the camera link is so short it’s just not radiating enough. They claim 30cm so you basically need the receiver in the same backpack as the phones. As phones get higher resolution and faster cameras this will become even less of an issue. Also, most importantly the camera has to be powered and running for this to work so just don’t take pictures of classified stuff while carrying around a weirdly warm battery bank an unusually attractive eastern European girl gave you as an engagement gift and you’re good.

    The actual target here is some sort of The Thing https://en.m.wikipedia.org/wiki/The_Thing_(listening_device) style attack where someone with a huge budget can get a wildly expensive device really close to a system through a significant human intelligence effort.

    The line of reasoning is valid though. These satellites will have some ability to track and intercept low power intentional emissions like WiFi and cellular packets. While these are encrypted there are still things you can do with the metadata.
