    It's exhilarating (for the lack of the knowledge of a better word) to see OpenAI and Anthropic starting getting hacked and getting a taste of their own medicine. Brings back hope that actual software engineering is not dead yet.

    > OpenAI confirmed both frontends rejected the reported messages, resolved the issue, and awarded a total bounty of $5,000.

    It requires the user to click a link. But I still find this bounty very low. Others may not report them if such a small bounty is given.

    • ibaikov 2 hours ago

      I took over user accounts in Microsoft Copilot (there are caveats but still), and they asked me to provide additional information of the exploit (they wanted a video) and before I sent it they fixed the vulnerability, didn't pay me a cent. Fair? Idk.

      • pvtmert 2 hours ago

        Typical $MSFT behavior, I can see why NightmareEclipse (ie. YellowKey zero-day exploit) got released without prior fix.

    • Catloafdev 2 hours ago

      A bounty like this is a polite "thanks asshole, fuck off, don't do it again" rate.

      Paying effectively nothing for vulnerabilities just means they don't want to deal with the program.

      Wild to think a company supposedly worth a $trillion+ is doing shit like this.

    • dgellow 5 hours ago

      That’s so low. That’s the level of bounty I awarded researchers when I was managing the bug bounty program at a small startup, it’s just ridiculous coming from a large company like OpenAI

      • amelius 4 hours ago

        But on the other hand, you can use AI now to find those vulnerabilities.

        • tescreal 3 hours ago

          If that is so, why doesn't OAI have a swarm doing this around the clock?

          • user43928 2 hours ago

            Surely with all their security programs, they would run testing on the ChatGPT implementation.

            I speculate that the AI didn't find this and that human effort and intuition for where to look were needed to find this vulnerability.

          • hxugufjfjf 2 hours ago

            Who says they don't? And if they don't, maybe its because others are using their hard-earned money to buy tokens from them to do it, so they don't really have to.

          • DeepSeaTortoise an hour ago

            Having bit the bullet, I found OAI's models actually quite helpful and most of their offering half-decent. But their whole German website was incredibly concerning and the only reason I went for it was people claiming they're not far behind Anthropic on coding and generally superior for everyday tasks like coming up with recipes to cook from your leftovers.

            Like half of the website was dysfunctiona and translations incredibly bad to the point of being nonsensical. That is if you were able to read them at all, because many just went off screen. Like, that's what your evil competitor does to your website after hijacking the domain, not you yourself, ffs

        • baxtr 4 hours ago

          They should have paid in tokens?

        • dgellow 2 hours ago

          A bounty amount is related to the blast radius and overall impact, not the effort required to find the issue

    • kamban 3 hours ago

      They have just announced free API credits for Pro plan users up to $500 per month. Irony.

      • zxilly 43 minutes ago

        To be fair, based on the profit margins indicated in DeepSeek’s reports, a $500 API credit might only cost them $5 to provide.

    • windexh8er 4 hours ago

      I find Sam Altman recent comments very "low" as well, neither matters. So in that case I think bounty hunters should just cold shoulder idiocracy and sell these to the underground. Let their customers be abused and complain about how OAI isn't protecting them. Each one of these types of events could cost them thousands of dollars in lost revenue and/or internal support.

      • rootnod3 an hour ago

        2 trillion $ companies should have the money to pay for these exploits. If they don’t, go tucking exploit them. If they don’t give a fuck about stealing knowledge from copyrighted material and private git repos, light em up.

        some people don’t want to be criminals as a matter of ethics

        but hey you do you

        • odyssey7 3 hours ago

          True, however:

          Ethics and legal requirements shouldn’t be conflated.

          There are times when ethics are a higher standard than what the law requires, and in that case the ethics are no less important.

          • codechicago277 3 hours ago

            This isn’t one of those times.

            Yes, you have a moral obligation to Sam Altman’s trillion dollar business.

            • BalinKing 2 hours ago

              On the contrary, many (including myself) would argue that "the victim's amount of money/power" has absolutely no ethical relevance: "You shall do no injustice in judgment; you shall not be partial to the poor nor defer to the great, but you are to judge your neighbor fairly" (Leviticus 19:15).

          Is it criminal to sell an exploit?

          • echoangle 2 hours ago

            Facilitation of a crime is a crime too. So I think in the US and most western countries, yes. At least if it gets used illegally later.

          • TheRoque 2 hours ago

            I don't think so, businesses like Zerodium bought zero days in plain sight and I don't think they faced legal consequences. They don't operate anymore though. So basically I'd say it depends who you sell it to and how.

        • windexh8er 10 minutes ago

          Treating people and businesses ethically that don't reciprocate doesn't work, clearly. Those people and businesses cry in their milk while they do exactly the same thing. There are no ethics in play here.

          But, hey if you want to defend billionaire narcissists that are destroying our planet and trying to take computing freedoms then I guess: you do you.

        • Black616Angel 3 hours ago

          Yeah, and some people just want the multi-billion dollar company that is currently destroying the planet while also permanently crippling social connections to just stop.

        • oth001 2 hours ago

          • dbspin 2 hours ago

            This isn't like stealing from a business. These are individuals most private conversations, potentially including their bank accounts etc. Poverty is no defence - and yes, I've spent a great deal of my life barely scraping by. You'll find poor people are significantly less tolerant of theft, especially from individuals, than rich. Whether that evidences the theft inherent in most forms of wealth generation I'll leave up to the reader.

    • thatsabadlook 5 hours ago

      Not worth the effort for a company supposedly worth a trillion dollars. The problem is oai can't afford all of its mistakes at the usual rate and they make bad press. A 100k bug could make a headline, but 5k for the same bug requires the average person to be educated enough to understand how bad these issues are.

      • varispeed 4 hours ago

        Should be given $5-10million under NDA. No headlines.

        • layer8 4 hours ago

          The bounty payouts must be public in order to serve as an incentive.

          • varispeed an hour ago

            That incentive works both ways. For instance employee sneaking in a security hole and then selling it to a mate so they can collect the bounty.

          Were they not right? Just like money giving you some runway but will run out, the exposure is still only a leveler, it's still up to you to take advantage of it.

          Also, they were not OpenAI.

      • dannyw 5 hours ago

        The "take over any instagram/meta account through their AI password reset chatbot" was going around and sold on shady forums for ~1 month before being patched.

      • throwaw12 5 hours ago

        then server side vulnerabilities should not be reported, instead sell the data, more profitable

        • petcat 4 hours ago

          Very few people would even have the knowledge of who, how, or where to "sell" such vulnerabilities. Going through a public bounty program is pretty much always preferable.

          Most people don't want to be felons.

            Don't worry, as more and more people get put of of work by AI the number of people willing to be felons will increase. Hell, they might even become president.

    $5000 is a joke. They pay millions to their top devs and still have more holes than a colander so a nice guy shows you a huge opening in your platform and all you can give him is a pat on the shoulder? Did you fire your top devs and hire that guy for a million bucks plus options? Did you sue the security firm you paid millions to audit the issues?

    I really hope they get hacked and crash down burning in flames like the Hindenburg

    • cbsks 3 hours ago

      I wonder if the new economics of finding bugs means that they pay the amount they think the tokens cost to find it.

      I think you know that the mentality of a company like this is “security is a risk but not a reward and whoever captures the reward kills everyone else”

  • usernametaken29 7 hours ago

    Now what about those millions of lines of code? Wasn’t the agent swarm supposed to take care of it? All jokes aside this is exactly what happens as you build larger monoliths, system complexity and bug surface increases logarithmically… so in all seriousness you want to reduce LOC as much as possible. Maybe this can teach OpenAI a lesson to produce software that’s correct and adhere to established engineering standards over sensationalised “we built so much code” promotional material.

    • torben-friis 6 hours ago

      Did you mean exponentially? Logarithmic increase doesn't sound too bad.

      • dahart 4 hours ago

        I’m sure exponential is what parent meant, but geometric (edit: polynomial) is what actually happens, not exponential. Code complexity increases linearly when it doesn’t interact with other features, and geometrically when it does. In the worst case, complexity increases as the square of lines of code. That is still very, very bad, but it’s not exponential.

        • ebertucc 4 hours ago

          What's the difference? From what I'm reading online geometric is just the discrete version of exponential

          • dahart 3 hours ago

            No difference, you’re right. I meant polynomial not geometric. :P

        • codechicago277 3 hours ago

          “Square of the lines of code”

          Sounds exponential

          • dahart 3 hours ago

            That’s quadratic, not exponential. 2^n != n^2

    • rglover 4 hours ago

      I like LOEC: Lines of Effective Code.

      Much easier to reason and make decisions if the bar is "yeah it exists, but is it effective relative to its intended purpose?" This weeds out buggy code as well as under performant code. If it's not effective (broken, too slow, etc), it either needs a refactor or thrown on the scrap pile.

    • pessimizer 2 hours ago

      > Now what about those millions of lines of code? Wasn’t the agent swarm supposed to take care of it?

      What's the joke? They're literally saying, every day, that this is true to a civilization endangering extent. They're making demands based on this, and politicians are taking up those demands.

      And now they're paying bullshit $5K bug bounties for account-stealing exploits on their own platform. They should have paid more just the make the bug seem more grandiose; I don't know who let them get away with this - this is what happens when CEOs run their own PR I guess. It's basically an public announcement that they're total fakes.

    • elendilm 6 hours ago

      Reducing attack surface is a lesson for everyone. Newcomers are impressed by massive piles of code.

      Seasoned developers are unimpressed, or even disgusted, by the same massive piles of code.

      • someothherguyy 5 hours ago

        i don't think LoC is the metric. sometimes fewer lines of code results in a larger attack surface through type coercion / widening, poor abstractions, hiding or stuffing behavior (modules that do everything), etc. to me, making code easy to understand, test, fuzz, and verify is more important. sometimes that requires more lines of code.

        • brazukadev 5 hours ago

          LoC *IS* the metric. It is obviously not perfect tho but still the best one to compare software surface. Including to compare the same solution in different languages and platforms. The less code you need to manage, the less code you need to change and the less code you need to hold in your head to understand it (or in the LLM context nowadays).

      If they or their company use email "security" software that "scans" all links it's not necessarily the users fault / they don't in fact click. The mail is auto-confirmed the second it hits the inbox.

      We've had to change our registration confirmation mails too recently to not confirm on GET only, but with another form - in hindsight it was stupid before but many services do that.

      • dpark 4 hours ago

        Security software fetching links will not trigger this behavior. It needs to be done in the context of the actual ChatGPT user so that a JavaScript payload can run.

        If merely GET on the link was sufficient to trigger the behaviors, the adversary generating the link would just GET it themselves.

        • kro 3 hours ago

          Yes, if it requires the user session (xss related), like the article, there is no problem.

          I was replying more generally about the "don't click links" advice and cases of server generated confirmation-token links (not saying this was the case at OpenAI)

    I think there was another HN discussion about it re bounty value and as far as I remember the issue is not that big companies are greedy in that case, but rather that over time it’s strategically better to have lower bounties so less people are interested in it.
