Deere just seems to be the most short-sighted company in the industry. I was in the market for a tiny tractor and even the fucking loader buckets are proprietary. Every other brand standardized on the skid steer/track loader interface so you can use all the attachments that are widely available but if you want to use them on a Deere you need to pay extra for a special adapter. There is literally nothing better about their system, it’s just designed to make you buy their attachments.

Broadly, because the only way to get it was from other humans. Specifically, because a lot of other humans essentially went out of their way to give it to other people.

Intrinsically/semantically no but the expectation is that the texts are encrypted at rest and the keys are password and/or tpm+biometric protected. That’s just how this works at this point. Also that’s the government standard for literally everything from handheld devices to satellites (yes, actually).

At this point one of the most likely threat vectors is someone just taking your shit. Things like border crossings, rubber stamped search warrants, cops raid your house because your roommate pissed them off, protests, needing to go home from work near a protest, on and on.

RF analysis is kinda difficult, you’d need to take the car out into the middle of nowhere and have access to fairly good equipment. A tinySA would maybe work if you’re very patient but data transmissions are generally very bursty so it may be difficult to nail down where it’s coming from in a sane amount of time.

One option would be to try to figure out if there are any FCC filings for your car. All filings will have pictures of whatever module is being used and what antenna systems it uses which may give you a good idea of where it is and what it looks like. There should be an FCC ID mentioned somewhere at the beginning or end of the cars manual. Googling that should bring up some stuff.

I hate that it needs to be said but love that they said it so plainly

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.

$250 per camera that you have to be within meters of best case. That doesn’t include the packaging cost to make this look innocuous so probably significantly more money if you wanted this to be stealthy and reliable. Add in the money for the distribution and “installation” of such devices.

This doesn’t scale at all.

It’s just a tempest attack. Firmware won’t fix anything but the attack is an extremely expensive nation state level operation that doesn’t scale.

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.

Part of the issue is the whole thing smells weird.

Like they won’t talk about their monetization strategy at all but they acknowledge that there will be one. They’re trying to randomly apply crypto to something that’s literally already the one proven blockchain tech, and they started at the height of the crypto token scam industry and it looks a lot like they’re trying to suck up the last dregs of that cycle.

If you are hammering crypto into things that don’t obviously need crypto you really need to justify it thoroughly. A relatively old company just hand waving all of it should raise all of the red flags.

They were shilling on HN too. People were getting frustrated because they were being incredibly evasive about their monetization strategy but, being HN, business model critiques were not well received…

Why the popularity in Yemen? Weird laws or something?

It would be an insane mistake to underestimate that group. Like the other comments said, they are the Taliban and the military/police. However even if they somehow weren’t, it still means we have potentially tens of millions of domestic terrorists running around armed to the teeth and that’s not a great feeling.

Yeah I’m becoming increasingly nervous with the blue states systematically trying to disarm everyone and the red states are trying to whip everyone into a traitorous frenzy over the dumbest shit while arming everyone with a pulse.

Otoh, and this probably sounds absolutely fucking nuts, I’ve found republicans tend to understand “strength” and they are strangely respectful of liberal and leftist gun owners because that’s a dynamic they can comprehend. It’s not a good state of affairs but it’s better than them believing they can just run things because they’re the only ones with “strength”

Ok I hate all of this.

They’re not the same, but they’re kind of the same personality type. They frequently care about the same things, they just want very aggressive change to fix them. The issue is the path to get there and those are wildly different in terms of what the problem is and the underlying world view.

Yeah the security angle gets parroted a lot, I’d call it more of a bad practice thing than a “omg you’ll definitely get haxxord”.

Otoh USB C as a spec is sort of necessarily a nightmare. It’s not hard to end up with shitty devices that’ll gleefully provide 20V when the system expects 5V and even if it’s just USB A, it’s not that hard to end up with 120/240v going straight into your phone.

At least with devices you own and control you know if they’re melting things and haven’t spent their lives being kicked/spilled on/cleaned with corrosive solvents or just generally old as hell and unmaintained.

Personally I bring my own because it’s faster and more reliable, and I have trust issues.

Just my opinion but I don’t really like the common belief of separating nation and non nation state actors. We’re getting to the point where nation states are making up a large portion of the really damaging attacks, and it’s frequently ones own government or a government they’re in conflict with which means there are very kinetic consequences for failure even if you’re a nobody. It’s not just someone stealing some money anymore.

The technical term is “dummy load”, most antennas are around 50ohm “impedance” which in an incredibly roundabout way means the antenna is indistinguishable from a 50ohm resistor at whatever frequency it’s tuned to…which means you can replace the antenna with a 50ohm resistor.

This all assumes you care about leaving the radio functional (radio amplifiers will burn up if they can’t dissipate the energy they’re creating) and in most cases it’s probably fine to just cut the trace as close to the source chip as possible. That said, if the system is especially evil and well engineered it’ll throw errors in some cases so better to leave everything functional but unable to hear or transmit.

I suppose there’s nothing wrong with it when the file is at rest, it looks like zip uses AES 128 or 256 which are adequate if you have a very strong password for the encryption. Ideally the encryption would feature a computationally intensive algorithm to slow guessing attempts when attempting to decrypt so you probably don’t want to use a weak password.

Usability won’t be great, you’ll be copy pasting constantly and that presents an opportunity for malware to spy on the paste buffer and steal your passwords but it’s a low to medium severity issue.

If you want to keep everything local I’d recommend KeePass, it’s free, open source, and very strong. It’s kinda the same thing but with the ability to insert passwords directly in some cases and can do more to keep everything organized.

If you want to use this in environments where you can’t install anything on the systems but don’t want anything online, this is probably acceptable though.
