<p>Yes, a hurdle to effective security research. Something hidden only <i>appears</i> to have no vulnerabilities. By raising the bar on a mass market product of this sort you ensure that in the event well funded actors develop exploits in secret they won't be inadvertently discovered by the public.</p>

<p>But the million dollar question is, do they rotate the IV per block or do they opt for speed as AMD and Intel both did by deriving it from the address and thus are vulnerable to someone sniffing the bus? (Note that older Intel server hardware wasn't vulnerable in this way but tracking IVs slowed everything down so they did away with it.)</p>

<p>They were always valid to question regardless but that doesn't mean intervention is inherently good (nor bad).<p>We actively work to prevent anyone with a suspended license from using the road, so does it follow that failing to do the same for convicted rapists is a bad thing?<p>I don't think "Facebook should allow all content that is within the bounds of the law of the local jurisdiction" is stupid at all. Ideally that's how infrastructure-esque operations should conduct themselves.</p>

<p>"Legal" and "perfectly okay" (aka socially acceptable or virtuous in some other way) are different things. If HN started paying people to post socially divisive content that wouldn't be okay at all (though it would almost certainly be legal).</p>

<p>They are a choice, yes, the same way anything is. They are neutral choices in the same way roads and other infrastructure "permitting" criminals to use them are. The fact that Meta does not choose to be neutral in all such cases is not an argument against that.</p>

<p>> there are no serious large scale countermeasures<p>For slow moving objects and an entrenched position there actually are but I have no idea how expensive it is to operate them nor what the practical constraints of deploying them might be.<p>> ban them now and make them hard to get, otherwise it's gonna start looking like that youtube video "Slaughterbots" really, really quick<p>I think you're forgetting the part where committing the crime is easy(ish) but covering your trail is nearly impossible. Most people aren't willing to martyr themselves for some abstract team red vs team blue extremist political nonsense that isn't severely impacting their day to day lives or the well being of their families.<p>It's vaguely similar to the reason that no one sabotages power stations. It's comparatively easy to do but carries severe downsides if caught and approximately no upside for the perpetrator regardless.</p>

<p>> Do you have any evidence supporting the claim that CCP has high resolution LiDAR point cloud maps of US cities?<p>I never claimed that - you aren't engaging with what I actually wrote.<p>I questioned the usefulness of such data in the general case. I also pointed out that in the rare cases where such data for a small area would prove useful it would be trivial to collect (on account of being a small area).<p>Just what sort of resolution do you believe is necessary or useful for drone warfare or other military uses? What do you have in mind here? Regardless, if I (a civilian) can afford the equipment and plane ticket to collect a LiDAR point cloud of a monument approximately anywhere in the world then any well funded actor can also send a "tourist" to do the same.<p>For that matter I don't think you even need LiDAR. Photogrammetry techniques can achieve arbitrarily high spatial resolution proportional to that of the input data. LiDAR just has some advantages if you're considering deploying on a wide scale or for certain realtime or power constrained tasks. Generally none of that applies to state actors.</p>

<p>You're handwaving. The xkcd point only applies if you're within ~3 sigma. This isn't a complicated statistical analysis it's just asking how far out the outlier is versus the standard deviation and size of the dataset.<p>To be clear I'm not claiming in one direction or the other. I feel that if you're going to attempt to discredit a piece of work it's on you to do such a basic check.<p>Really the whole point of that xkcd was to viscerally illustrate the practical effect of binary misclassification, or alternatively to make the point that a p of 0.05 isn't necessarily as rigorous as you might expect. Neither of those things directly applies here.</p>

<p>Outliers, sure. Exactly like this though? That depends. Since this is a population then assuming a gaussian (which could well be wrong for a variety of reasons I'm just guessing here) what's sigma? If 1/100 is within ~3 sigma then sure. Otherwise no.</p>

<p>I realize that. I didn't say "publicly available" but rather that anyone important has access to the information that they want. I expect that any exceptions to that can be trivially remedied on a case by case basis.<p>It's a matter of scale. Satellite imagery gets you most of the way there. I can think of only a very few instances where you'd care about higher resolution and those should be few enough that any well funded actor (ie the ones we care about here) can perform targeted data collection.</p>

<p>Isn't it a simple matter of sustained energy output scaled by the overall efficiency? I'm saying that a human cycling can sustain much <i>much</i> higher energy output for much longer than most other forms of exercise. Running probably comes close and swimming likely exceeds both of those but in the latter two cases I'm not clear how you could productively harness energy from the activity with any sort of efficiency so it doesn't apply here.</p>

<p>What does this accomplish versus directly banning the collection and exfiltration of data by foreign actors via consumer products? Like just make it illegal for products to unilaterally and automatically upload broad swaths of sensor data to foreign clouds (or preferably <i>any</i> clouds) and then prosecute any offenders. What am I missing?</p>

<p>Is that really any surprise? Consumers are cost sensitive and have you seen the morass of obtuse and pointless regulations surrounding drones in the US? Meanwhile the military can do whatever it likes and has much deeper pockets.<p>The cherry on top is how utterly unenforceable (in a practical non-proliferation sense) the bulk of the regulations are. Strap a microcontroller dev board to anything sufficiently lightweight and it can become a drone. The most expensive part of a DIY heavy lift build that breaks ~all the rules is probably the props.</p>
