    No, your paranoia-outage is the true "national security threat" - a threat to freedom. Stop fanning the flames and calling for more government intervention.

    • DocTomoe 2 hours ago

      After decades of watching people use these three words, I've come to the conclusion that 'national security threat' is a right-wing dog-whistle for 'we have no actual proof, but we dislike it, so let's ban it'.

      They are basically 'won't someone please think of the children?', but with higher stakes.

        it's a general politician dogwhistle, don't underestimate "the left" (especially in countries like the US, where the democrats are really not that left compared to other left parties in e.g. europe; leaving you with a pointless right-wing vs right-wing fight where nobody wins)

    If someone with informed consent wants to run a residential proxy, that's their right and unlikely to be a national-security problem.

    When it comes to involunary proxies, those are really just one of many possible symptoms stemming from a real problem: Shitty security. (Edit: And shitty contract/privacy laws.)

    Shitty security is tolerated by our markets, is is protected from fixes due to copyright law, and it is even encouraged by parts of our government that want to exploit the flaws. We will gain far more from fundamental quality-improvements than we will from whack-a-mole-ing on this symptom.

      I'd be interested in the stats showing what percentage of residential proxies have 'informed consent', and the scale of what 'informed' means beyond "included in terms and conditions".

      > We will gain far more from fundamental quality-improvements than we will from whack-a-mole-ing on this symptom.

      100%, but I feel like that's both true and rarely executed upon in most governments for most topics.

    If anyone is curious where this leads to, I will happily point to China, Kazakhstan and Russia as prime examples.

    Can’t wait to have our very own Roskomnadzor MITMing everything and national security laws mandating Kazakhstan style TLS interception on every single device.

    Just a small over the air update via your friendly neighbourhood corporations Microsoft, Apple and Google.

    You know. To keep you safe.

    My personal opinion is they're not hard to detect at all. Latency is a huge giveaway, If the client can't respond in a time you'd expect a client to be able to based on its geographic location, that's a pretty big tell they're using proxies. In fact, if you did latency sensitive stuff, you'd likely find out whether you wanted to or not.

    They have their problems but how else am I supposed to scrape data from companies that want to hide it?

    • BLKNSLVR 3 hours ago

      I'm a bit on the fence about this, but leaning towards the "bad luck". I'm sure there's a large swathe of nuance that I'm missing, but my simplistic view is: If they don't want to be scraped then they don't get included in "the thing" which, at minimum, is a data point for consumers to make consumer decisions about.

      It strongly depends on how scraped data is being used.

      If your 'cat' hasn't been able to catch their 'mouse' then the cat needs to get smarter, or look for alternative sources of mice, or the cat should be considered 'unviable'.

      Have you approached them to get access to their data? Have you explained to them how your service can benefit their business?

      (I generally come from a position of suspicion as to why someone wants to scrape data that the owner goes to certain lengths to protect, but then I'm also an 'information wants to be free' kinda person, but the Internet is increasingly an untrustworthy place, so security is overruling narrative).

      • AnthonyMouse 2 hours ago

        > I generally come from a position of suspicion as to why someone wants to scrape data that the owner goes to certain lengths to protect

        Let's try this for example. Suppose you want to create a price comparison site.

        A lot of the major retailers don't want these, because they want the customer going to their site when they want to buy something, not to the price comparison site that tells the customer which retailer has the best price and then might not always be them.

        If the comparison site doesn't have the prices from retailers who sometimes have the best price then it can't serve its function -- customers still have to check sites manually. And comparison sites are pro-consumer whereas blocking them is anti-competitive, so the ones doing the scraping are the good guys.

        • BLKNSLVR 2 hours ago

          Suppose someone wants to create a price comparison site, but is unable to access all the data that would serve their customers in finding the lowest price.

          The I guess the site is either useless, or can be used in combination with customer's own research that includes sites not included in the comparison. The site is still useful, it's just not exhaustive. There's nothing much in the world that's exhaustive, it's all a range of percentages.

          Also, maybe the source that isn't scrape-able becomes less popular as a result of not being included in the price comparison list. If they're always more expensive, then neither you nor they have any advantage in listing on your site. If they're always cheaper, then your site may have no purpose to serve.

          Everyone seems to want _everything_ despite _everything_ not being necessary to provide a service. The lack of a certain set of data may itself be a data point, and should be used as marketing material for or against the company resisting the scraping.

          Just because residential proxies are somewhat of an 'easy answer' doesn't mean they're right. Use more creativity and imagination! Or follow a new idea. It's not like price comparison sites are a revolutionary idea.

          (I'm a consumer who happily does significant research before a buying decision, going to various sites and checking prices, warranties, model numbers, reviews, availability, delivery times, and all the shit. And prefer doing the research myself than trusting a price comparison site, so I'm not the target market, thus my bias in my commentary and opinion on that topic).

          > so the ones doing the scraping are the good guys.

          Everyone thinks they're the good guys. If there's profit involved then there's always an element of delusion.

        Take reddit for example. If you're not big tech they ignore you.

        • BLKNSLVR 2 hours ago

          I'm kinda "fuck reddit".

          That's cutting the tether from a _lot_ (there's no way to overstate this) of useful information, but that's potentially one of the great things about the open AI/LLM models, is that all that info is baked in there.

          Disclaimer: As far as I understand it. Please educate me if I'm way off the mark.

          Also, how much of the content of reddit is in Common Crawl? (same disclaimer applies to this comment)

          I also understand 'the archival mindset', I hoard a bunch of data. But I also understand the logarithmic graph of futility.

      • harimau777 3 hours ago

        I know there've been efforts to scrape information that MAGA is trying to purge from government websites.

        • BLKNSLVR 2 hours ago

          Government website data should be openly available one way or another (at least within the country, and with reasonable security provision against obvious maliciousness).

          If it has to be scraped then there may be other problems (which include lack of resources to make the data API accessible).

    • BLKNSLVR 2 hours ago

      Apologies for the double post, but I've got an alternate perspective:

      Do you allow the data you've scraped to be scraped? Do you share it as freely as you desire the 'companies that want to hide it' would? Or do you consider the scraped data is 'hard earned reward for effort' and therefore has value that others should subscribe to your service for?

      This is just the largest residential proxy provider BrightData(previously Luminati that used a free VPN to source residential bandwidth)

      The overall residential proxy market is too large and often undetected by intelligence tools. BrightData is actually much more compliant and malicious actors wouldn't be allowed access. They have an extensive KYC and use-case vetting process.

    No they aren't.

    > Actual data and identity loss of American citizens.

    > Malware that can record video and audio from infected devices.

    > Infrastructure for foreign covert influence campaigns.

    > Botnets used in hacking and DoS attacks

    These things have existed for 20+ years. Bad but not exactly a national security threat.

      Yea, but with AI we also have seen unprecedented amount of hackings etc.. using these residential proxies. Now even normal plebs can do so much harm.

      • himata4113 3 hours ago

        So it's okay for organized crime to do it, but not normal plebs? The former is obviously a lot more harmful and in reality this is just a wakeup call to get their shit together.

        People were dismissive of security far too long. I think it's actually good that AI instills some fear into people causing it to take a lot more seriously than they have previously done so.

    Ad networks like meta ads, google ads use residential IPs + small LLM to check landing page of your advertisers for malware and scams. They are already paying millions for this service.

    Sometimes their system malfunctions (cough cough) and you get charged for those clicks but you fail to report them as fraudulent as you've no proof as the IPs and useragent all appear normal to ad agencies and advertisers.

      That’s a scary read.

  • indianmouse 2 hours ago

    Anything connected to network can become a national security threat. IoT devices, internet connected smart appliances and all. Computers that run some OS is least of the worry because of the various layers of protection that can be added to them. But it is not the case with the IoT devices or SMART(!) devices where, if the firmware or any app ecosystem gets hacked / cracked / modified or sideloaded without any user intervention, could turn into a large zombie C2C botnet that can cause havoc.

    Proxying is least of the worries!

    When manufacturers bring out the smart features that require constant data collection, monitoring (obviously in the name of service quality, troubleshooting, firmware / app updates and subscription of services (!!)), it is oblivious to the fact that security and privacy at a personal / state / national level is never considered (for various reasons such as the design, profit interests and overheads / compliance perspectives and what not!) to be part of the ecosystem. Bad actors with sufficient knowledge and tools could exploit and profit from it.

    It has become more of a planned obsolescence / profit / greed based industrial / corporate culture in rolling out unwanted stuff / monitoring and controlling as a feature that gets exploited to the core.

    Honesntly, I don't have an answer for that, but have some thoughts that I wanted to share.

    I do not want a cleaning robot or a water purifier or a printer or a TV or a refrigerator or an oven or a smart light bulb or a smart lock or even my car to have undisclosed, unwarranted connectivity to internet for whatever reasons.

    I do not care if it is the manufacture or the service provider or whomsoever it may be!

    I want all of the network connectivity options to be explained with all the controlling options and boundaries and data collection that happens on any of the connected medium to be as much transparent with the option of preventing or restricting what one does not want to go out of the device.

    Will anyone do that?

    It ill never happen! Sadly!

    This problem will balloon further without adequate controls and killing the networking at a ground level would only be the only solution!

    But, in the case of a connected device having an inbuilt connectivity option (like the m2m based options) in a smart vehicle, even that is not possible!

  • armchairhacker 3 hours ago

    Residential proxies are necessary to access services that try to ban VPNs without compromising anonymity. If they’re banned, it’s easier for websites to require information that can be used to track you (IP address), since most people don’t use VPNs they won’t care.

    More importantly, a residential proxy can be mutual. If a group of people agree to forward traffic to each others’ IP, how is it not their business? It obfuscates their identities, but this is the Internet, not e.g. a government office or test center where you obviously can’t walk in with someone else’s ID.

    Banning non-consensual proxies makes sense since those are effectively malware, even though they make anonymity harder, so does banning theft and here you’re stealing someone’s internet. I’m sure we can convince enough laymen to knowingly install proxies by paying them.

    • BLKNSLVR 2 hours ago

      I think the fact that they're laymen means that there's still a pocket of non-consensuality. Taking advantage of someone's ignorance of potential consequences is as bad as malware in my opinion. If you're outlining all the potential bad outcomes before signing up a 'mark', then that's slightly more OK.

      Myself being "not a layman" would definitely not allow anonymous usage of Internet that's tied to my home/residence/identity to be used by some internet rando just because they pay me money.

      I would support, however, small family/friends groups who know and trust each other well enough to not do anything that'll cause a police raid on each others homes (having endured a police raid and the ensuing 8 months of not being told anything about the progress of whatever they're doing, it's not something I'd wish on a stranger, never mind a friend/family member).

    I don’t understand this being a “national security” threat.

    Besides, mobile proxies exist which work differently. All you need is a mobile data plan that you run a proxy server on. It allows for easy IP rotation and since it’s a pool shared with other customers you cannot easily block it. This is because of things like CGNAT.

    IP rotation is easy because reconnecting to the network gives you a new IP address.

    Static residential proxies also are a thing, even if they are less effective sometimes.

  • anabis 3 hours ago

    It's an anti-consumer evil practice, but if it is a national threat that's on the nation's security infra.

    • BLKNSLVR 2 hours ago

      somewhat related to @iammrpayments comment, the S in IoT stands for security.

      The nation's security infra is a reflection of the nation's security legislation and regulation.

    The optimum amount of residential proxies is non-zero.

  • Shank 4 hours ago

    Citation needed? I'm not a fan of residential proxies but these are pretty wild claims that aren't substantiated. Calling them a "national security threat" implies it is a threat to e.g., the continued existence of the United States. Is it really that? All of the activities described are already violations of the Computer Fraud and Abuse Act.

    > At the very least, major American ISPs (Comcast, AT&T) should detect clearly suspicious activity coming from customer IPs and warn them to scan their computers, check their TV apps, and find whatever is turning their internet into a proxy.

    What are we saying? Really, what are we saying? We should turn domestic ISPs into domestic surveillance apparatuses to "detect clearly suspicious activity"? What is "clearly suspicious activity"? Section 230 is still law.

      The router could also be a good place to display live TCP usage and last 30 days usage and other network activity. There should also be a service that can identify whether specific IP addresses belong to botnets or other malicious infrastructure. If there are any abnormal activity mobile app can notify the user.

      Governments could even purchase residential proxies themselves and check whether they're being used for malicious activity.

      It isn't that difficult, but I guess governments just aren't that interested.

        > It isn't that difficult, but I guess governments just aren't that interested.

        I recently switched from my previous ISP because they randomly broke my ability to use my own router, and during the time when I had to default to using their own modem/router hardware before I could get the new ISP to come and set things up, I could barely even get a signal in my office upstairs (which had previously been connected via a mesh endpoint) because their router didn't expose any way for me to split 5 GHz and 2.4 GHz, and the router absolutely refused to let my devices connect via 2.4 GHz despite them having more than 90% packet loss due to the weak 5 GHz signal.

        Regardless of how "easy" it is, I don't trust ISPs not to screw it up somehow and probably cause a lot more concrete damage (even if the individual issues they cause are smaller in magnitude) than the theoretical concerns of "national security" that, as far as I can tell from reading this thread, have caused a total of like a few hours of downtime one day in a couple decades.

    Oh please. An IP address is an IP address. The whole idea that some IPs are more special than others flies in the face of net neutrality.

    • BLKNSLVR 2 hours ago

      Disagree fairly strongly. IP addresses known to be malicious are unequal and should be treated as such.

      Just because the idea of net neutrality exists doesn't mean it's true. I'm sure there's a specific context for it, and 'security' is not that context. It was about data/packet prioritisation wasn't it? Unrelated to security.

  • bsder an hour ago

    The "solution" is to shoot CGNAT and to finally force the ISPs to adopt IPv6 so everybody can drop the addresses of a detected residential proxy into a ban list.

    Continuing to allow CGNAT is what allows the residential proxies to hide because it tumbles the IP identity of bad actors with normal people.

    They're also a wholly necessary endeavor until the surveillance industry stops discriminating against IP ranges with endless captcha nagwalls. That, including its likely next development of remote attestation, is a much deeper problem for individual liberty. Individual liberty is itself more important than "national security" (which is more about protecting the government rather than the People) and thus needs to be addressed first.

    Yes, yes, we should fight deceptive software that doesn't disclose it has a proxy function. Fine. But there's no way to square 1) fighting all residential proxies, including ones run with informed consent and 2) preserving the public's access to general-purpose compute at home.

      Very well: your ISPs, telecomm providers, and cloud services also own computers, and they should be able to run whatever they want on the devices they own, and they choose to block all your traffic, block all traffic destined for your premises, and flag your hardware IDs in certain databases, which is software they choose to run because they own the servers.
