    You can just do what my university did, hire a small shell firm with 3 employees to hold all your data, and when it got hacked they just went bankrupt and we switched to a new shell firm with similar form and function.

    Minimizes money usage and does not require any security investments

        Some hard to swallow pills for tech companies in 2026: data not collected in the first place cannot leak.
        • SoftTalker 39 minutes ago
          Followed by deleting data once you've used it for its stated purpose.

          Personal data needs to be much more of a liability than it currently is for anything to change. Business will respond when the bottom line is affected.

      • AIiscoming 2 hours ago
        Lets be honest here, this is a business risk which is crazy high. As stupid as this is, I care but i can't guarantee it.

        I might suggest a construct like this too.

        What do you think how much it cost to do it perfect?

        • louthy 2 hours ago
          Perfect isn’t required. The bar is “gross negligence”. Perfect is impossible, but proper compliance procedures, proper process, and a commitment to following industry best practice will always see you on the right side of the negligence bar, even if something slipped through the net.

          It’s the difference between being a professional and an amateur (or worse, a ‘cowboy’).

          • augment_me 1 hour ago
            Again this is not priced in. Every rational(in terms of revenue) business would rather be a highly profitable "amateur" compared to a barely profitable "professional".

            There is no capitalist incentive for the latter, and you will lose market share to firms that can undercut you because of their lower costs.

              This is literally the point of data breach laws like this. To provide a financial incentive to take this stuff seriously.

            • louthy 1 hour ago
              4% of revenue in the EU, 4% of revenue in the UK, and 10% of revenue in Korea should be enough of an incentive to start caring about how you deal with your customer’s privacy and personal data.

              One assumes the rest of the world won’t be far behind, apart from the the corrupt land of the USA which is going backwards right now.

              • augment_me 1 hour ago
                So we get to a very easy formula for companies to do in the EU and UK:

                If (4% of your revenue * risk_of_breach_with_your_security < cost of outsourcing storage to a 3rd party cloud) {

                Roll your own security solution

                } Else {

                Outsource to 3rd party

                }

                  Your replies here suggest a level of cynicism that is, well, … , it ain’t pretty.

                  In my experience, putting proper compliance procedures in place, following industry best practice in relation to data management and data security actually leads to a more effective organisation, because it professionalises.

                  It’s the first step out of the ad-hoc phase of a startup and into the real world of creating a business with value. It also means as you scale up the personnel in the organisation, there are proper checks and balances in place.

                  When you come to sell your business, if it has a ton of existential risks attached to it, it will be worth less and may even not be sellable at all. So even from a cynical “all I care about is money” point-of-view, you want a business that is sound and isn’t storage for future law suits or fines.

                  Also, the cost of a fine due to a data breach isn’t the only thing to be concerned about. Gross negligence could lead loss of life, loss of property, loss of earnings, etc. and the buck stops with the executives — don’t think you can’t be completely fucked by the good ol’ law as it stands today.

                  Some businesses are more vulnerable than others, but that’s also why you scale the compliance architecture to the business.

                    > Your replies here suggest a level of cynicism that is, well, … , it ain’t pretty. It seems you think “fuck the human cost as long as I’m making money”. I’d suggest changing your outlook on life if I didn’t feel like it wasn’t such a lost cause.

                    This is the default business mindset. Push every rule and regulation to the limit in the name of profit, if you can break a rule with minimal concequsnces then pay the fine and move on.

                    Stellantis has a recall out for >1M vehicles because they catch fire even when turned off. Unless that kind of fuckup is met with business threatening fines it will happen again.

                      It isn’t, it is how some people approach business. Not all.

                      Again, this is just cynical and constantly, almost psychopathically, propagated here as though it’s some kind of virtue of business or the only way a business can be ‘pure’.

                      It just isn’t.

                  • rpdillon 36 minutes ago
                    The person you're replying to is citing the incentives that are created. That's not cynicism, it's analyzing motives to help model outcomes.

                    As for the buck stopping with the executives: can you apply this to a case I've heard of? We have multiple data breaches of companies that scan IDs. We have the Experian breach. We have multiple LastPass breaches. Is there any executive at any of these companies that has been held accountable?

                    I've actually done the legwork on the ones I just mentioned and the answer is there have been no criminal or civil penalties to any individual in an executive role at any of those companies as a result of the data breaches. Maybe I'm missing one?

                    • louthy 14 minutes ago
                      Maybe I wasn’t clear in my message. But the buck stopping with the executives is when ‘the company’ breaks law. Usually because of gross negligence or corporate manslaughter.

                      With my last company, managing medical records, I was always conscious that if we didn’t take our responsibility of managing medical data correctly it could lead to the death of one of my customer’s patients; or some other extreme circumstance that the executives could be held liable for.

                      That was my point about being professional, if you have proper processes in place and audits to prove it, you have protection. And only the most egregious cases would land.

                      It’s good business to protect yourself from a gross negligence or corporate manslaughter claim. Presumably, the reason you don’t hear much about executives in the dock for these crimes is because most professional organisations put these processes in place.

                      Again, I was just stating that it isn’t just data-breach fines that should encourage someone to improve the processes within their organisation.

              • fc417fc802 1 hour ago
                It's only an incentive to start caring if it's cheaper than circumventing the law. In other words it won't work unless the aforementioned liability loophole is closed.

                To rephrase the comment you replied to, if being a cowboy is more profitable (by whatever shady means) then that will generally be preferred by the market. Despite whatever sensibilities you or I might have there is no escaping that simple truth of capitalism.

      • pluc 2 hours ago
        Every single tool being released since like 2024 is pushing everyone to care less and less and to let agents handle more and more. We are not trending towards increased quality, resilience and reliability - even though we've been obsessing over these things for the past 20 years.

          Yes, being competent requires effort.

          It certainly feels much better being an proactive member of society rather than a self-serving arsehole though.

          So, there is that.

          • nostrademons 2 hours ago
            It feels better only as long as everybody else cares too. Being the only one competent in a room of imbeciles is a terrible feeling.

            Hmm, this is perhaps why we get socially-negative businesses that often have very friendly (and driven, and hard-working, and intelligent) internal cultures. Competency becomes a fault line. When it becomes obvious that a large fraction of humanity just doesn't give a shit, a small group of people who are competent and driven turn their efforts to taking advantage of people who don't give a shit. Thus creating industries like market-makers, cryptocurrency, advertising, and AI.

            • louthy 2 hours ago
              > It feels better only as long as everybody else cares too.

              Not sure who “everybody else” is in your statement, but as someone who founded a healthcare tech platform (since sold) [1], I spent 20 years caring about the many millions of patient medical records we held and making sure my team cared too. In my mind it wasn’t optional.

              I did it because:

              * it’s the right thing to do

              * for professional pride

              * and so I could sleep at night

              And, at least at the beginning, I believed a data breach could be the death knell of the company. Over time the laissez faire attitude to data protection, by the industry as a whole, made it seem like a breach would be survivable, but luckily we never tested that theory.

              I still walked away from it a wealthy man. Being competent and caring about your customers (and being able to sleep at night) doesn’t have to mean failure like it seems everyone here thinks.

              • rpdillon 33 minutes ago
                People don't think caring about your customers leads to failure, but it's a lot harder than not caring, and it does seem to be the case that it is mandatory to not care if you're going to be chasing massive valuations.

                We're moving from a high trust society to a low trust society, I fear. It's a tough transition.

                • louthy 0 minutes ago
                  I realise I’m a sample size of 1, but for me caring was good for business: caring means you can empathise, if you can empathise you can understand, if you can understand you can build a better product.
        • zelphirkalt 1 hour ago
          A university which doesn't care to protect its students, deserves to get its whatever-license/accredited status checked/audited.
      • toomuchtodo 2 hours ago
        Caring is orthogonal to profits and shareholder value. The one who cares the least wins unless economic incentives change this math, which is what these financial penalties work towards. Humans are tricky.

        To defend against the threat OP talks about (intentionally under capitalized corporate entity to avoided liability), insurance should be required, and your cyber insurance underwriter will perform an audit as part of underwriting. It's effectively a bond against fuckery in this context.

        (cyber consultant and practitioner)

        • my-huge-pony 2 hours ago
          Why the middle man? Can't we make the law so that the University is still liable for the data beach because it's "their" data (collected/stored on their behalf) that is breached?

          I think that still aligns the incentives, and University in this case has interest to make sure the data is stored properly.

          • augment_me 2 hours ago
            This is already the law, but the shell company signs the ownership of the data and the security responsility. The university in this case is just using APIs to load and store stuff to someone else's servers.

            If this is not possible no cloud storage would ever be possible to be liable for anything. Your Google drive got hacked? Your responsibility.

          • SoftTalker 2 hours ago
            Insurance only pays for damages, up to the limit of coverage. It does not do anything to remove liability.
        • x3n0ph3n3 2 hours ago
          That's not what orthogonal means. Saying they are orthogonal means that you can care and be profitable.
          • toomuchtodo 2 hours ago
            You can care and be profitable, but it is usually cheaper to not unless regulatory mechanisms exist to internalize this potential externality. Can't rely on humans to do the right thing, some will not unless they feel pain for doing the wrong thing. Ergo, we build systems (legal, regulatory, technical, people) to encourage the desired target outcome(s).

            I've worked with very profitable firms who care very little (and it shows in their systems and how they operate in this regard), and barely profitable firms who do everything right. What's the difference? Their culture, people, and internal incentives.

            TLDR Security failures and data breach fines must be more expensive than the happy path and doing the right things. This encourages the happy path and doing the right thing, while discouraging doing not enough or nothing.

            • bluGill 2 hours ago
              There is a lot more than regulations. Reputation is important as well. While you can give up a reputation fairly quickly, it is very hard to get/keep. Many companies are well aware of the value of their reputation - they call it the value of the brand.

      That's like blaming Seagate when your harddisk fails.

      No judge will fall for that. You should have made backups. And you are responsible for the data of your clients.

      • augment_me 2 hours ago
        Not really, the shell company is the owner of the data and is responsible for the security of it by contract, that's the whole point.

        Seagate will not in a million years sign anything like this when you buy a HDD.

        • louthy 1 hour ago
          That’s not how it works. Especially with compliance schemes like ISO27001, Hippa, etc. they require an audit chain through the supply line. Obviously it depends on what data you’re managing to whether your customers care about whether you’re audited, or not, but if you’re selling enterprise software then this is all part of your compliance process. You can’t offload that responsibility, you have to make sure your suppliers comply too.
          • augment_me 1 hour ago
            Maybe it's different in the US, but in the EU you can get certified to be able to handle certain data securely, for example getting SOC/ISO/ESC certifications. When you then are looking for storage solutions you can in practice absolve yourself from liability/gross negligence if you choose a provider that has these certifications. So when an org needs cheap solutions, they find the cheapest compliant provider and hands are clean.
            • louthy 1 hour ago
              If you want to be certified for SOC or ISO in the US you have to check all your suppliers too. You can’t outsource your responsibility if you want to comply. I know this because I have been through it in the US, EU, and UK.

              If your supplier has these compliance audits in place and has the documentation to prove it, this isn’t “absolving”, it’s literally the diligence process.

              But a “shell company”, as per your original comment, is not going to reach a compliance threshold to allow the diligence chain to succeed. Just from a business continuity point of view they would fail, but there are plenty of other areas that would be problematic from a compliance standpoint.

        • xboxnolifes 1 hour ago
          You can't just absolve yourself of responsibility by saying "I hired a contractor". You are still responsible for doing your due diligence in picking your contractor.
        • SoftTalker 2 hours ago
          It's not that easy. Companies are required to do due diligence on stuff like this. If they know (or should have known) that they are outsourcing something to an incompetent provider, they could still be liable.

    This is exactly what we need in the West! I have a strong suspicion that nobody here actually cares about security or customer data being spilled into the streets.

    "through intent or gross negligence"

    I'm not familiar with Korean law but that seems a rather high bar. I don't think we'll see many fines actually levied.

    • bluGill 2 hours ago
      The hope is they levy few fines. When you want to make money you set the fines such that they are "a cost of doing business". Most often you don't even call them fines, you call them a permit/license fee (though fines are also common). When you want to prevent a behavior you make the costs high enough that it is worth the effort to not pay them in the first place.

      (I'm assuming here that 10% is high enough that nobody would call it a cost of doing business - I could be wrong)

    Assuming global adoption, this would also have the side effect of increasing bug bounty payouts. Consider the recent OpenAI compromise: an attack RCE, an SSO configuration flaw, and subsequent employee account takeover, for a mere $6500 bounty for a trillion-dollar company.
  • xp84 51 minutes ago
    I'm assuming the intent is to protect customers.

    Tying the fine to intent or gross negligence doesn't work for me, as a customer doesn't care why, they only care that the harm happened. Doesn't matter to me if you train everyone really well and one guy forgot his training just one time, or if you don't train at all.

    I'm thinking:

    (The following example is in "American" terms, I assume some other countries have similar ideas as SSN though)

    - Name and address or name and phone number leak: $100 per customer affected.

    - Email: $50 per customer affected, or $100 if tied to any other data.

    - Social Security numbers: $2000 per customer affected

    - Unsalted or plaintext passwords: $500 per customer affected.

    - Cap is the greater of 200% of annual EBITDA, or 20% of revenue

    Money goes to the government to be distributed DIRECTLY (tax-free) to the affected users.

    This might bankrupt a couple of companies in particularly bad breaches, while companies are still getting used to it. Good! I hope it does and that business textbooks highlight those disasters, the way they do the Enron collapse.

    My goals for this system are for businesses to properly price in the risk of holding (or even momentarily touching) sensitive data. SSNs, for instance should already (in a sane world) be radioactive for any business to even CONSIDER touching. To the extent any business feels the need to collect or hold it, frankly I'd say, think again. Credit reporting agencies are the worst offenders (and under my rules Equifax would already be gone), as they maintain databases with that as primary key, and force all their customers to deal in that key, instead of taking advantage of some 1990s technology like one-way hashing, or better yet, coming up with their own identifiers that could be replaced responsibly in the case of breaches.

    Sounds great if all the following is true.

    * Before Tax Revenue

    * If the company is owned by another company, the revenue is the total of all companies owned by the highest level parent.

    * Includes Worldwide Revenue

    * Includes companies based in all other Countries.

    • zelphirkalt 51 minutes ago

    I would like to make a wager on this law being ignored the first time Samsung or another chaebol violates it and is facing a fine equal to 10% of revenue. I can almost guarantee it, it’s a high enough fine to turn some low-margin businesses from profitable to unprofitable for the year and there’s no such thing as a secure computer system. The only way to guarantee compliance is to not store any data which isn’t exactly reasonable for some business models.
    • Retro_Dev 2 hours ago
      > there’s no such thing as a secure computer system

      Where is your source for this? It is entirely possible to make a secure computer system, though it does require effort. The article specifically mentions "up to" 10% and the fines applying to companies leaking data on purpose or through negligence. I doubt the fines will be nearly as high for a company that tries to secure a system (and thus prevents more leaks) rather than a company that does not try to secure a system (assuming that leaks will occur), if the same breach happens.

      Computers are deterministic (excluding cases where practically impossible cosmic ray events occur), so while we have the power to ensure system security, we should ensure system security. Heck, even just encrypting consumer information and protecting just the keys to this data would already decrease the effectiveness of many data breaches.
