    >Microsoft had editorial control over this post, cutting sections and figures and reshaping how the impact is described before publication.

    that is... not great. shame on microsoft.

    its actions like that which shed light on why we get the nighmare eclipses of the world. pressuring a kid into handing over full editorial control of a disclosure is gross.

      Love to hear more on the motivation for agreeing to this.

      e.g. The $5000? Amnesty from being sued?

        Also he's 16. I'd definitely be less willing to push back (especially on something like this) at his age
        • p-e-w 28 minutes ago
          Of course not. You don’t push back on something like that. You hire a lawyer and let them do the pushing for you. If you contact the right NGO, they might even give you one for free.

          There’s no way I’d sign any agreement with a company like Microsoft regarding an issue like that without a lawyer. I’d rather not disclose at all if those were the only options.

            I don't know about you, but when I was 16, I never hired a lawyer, and none of the other 16 year olds I knew had either

          I will tell my story: I found a huge accounting error that allowed for several employees to embezzle funds. I disclosed it to the main stakeholders and some people went to jail. The accounting team still refused to acknowledge that the mistake was theirs, so I left on principle.

          A few weeks later, I was talking to an old colleague and they revealed that the story that came from stakeholders was that the accounting team found the error, and I left in disgrace (despite that not being my department?).

          So if you find an embarrassing mistake and you do not control the narrative, you have to proceed very carefully.

    > awarded $5000

    It's a little perplexing. Of course it's always a controversial topic since it's difficult to value an exploit, but whenever we read about these online, which probably goes through some survivorship bias, they seem pretty low.

    On https://www.microsoft.com/en-us/msrc/bounty it seems the top is $100,000 or $250,000 depending which program this counts under.

    What does HN think? Why would it be only $5000?

    • giancarlostoro 17 minutes ago
      What's worse is the alternative is winding up like Aaron Swartz... (all he did was scrape PDFs for mostly public funded / tax funded papers) Which is even worse, I think I'd be glad to receive $20 for Starbucks instead of being legally chased for showing them they messed up.

      There should really be laws for protecting security researchers who produce 0 harm and divulge / share a vulnerability with a service provider. I'd rather the floor be getting no money AND not going to jail or being sued.

      As I understand it, bug bounty awards are a rough proxy for "would nation-state actors be able to exploit this for operational purposes without getting caught".

      Zero-click iPhone exploits that affect the current OS and also previous ones are worth hundreds of thousands.

      • yieldcrv 49 minutes ago
        thats the true market value of bug bounty awards

        the unilaterally set awards by the affected corporation are far lower and based on the price of the researcher’s liability

      • buckle8017 1 hour ago
        Try 10-20 million USD for a zero click iPhone exploit.
    • TeMPOraL 21 minutes ago
      I think HN, like a lot of people in this industry, have strongly skewed perception of the actual importance of these bugs.

      You could view the bounty prices as market evidence that most of this is rightfully treated as nothingburgers. I.e. the alternative to paying $5000 to some random person for this class of vulnerability research is not risking a trillion dollar hack the next day - it's just risking shmaybe some kerfuffle down the line, followed by fixing it through normal triage process. The bounty program is as much marketing as security, and $5000 is probably about the right price for marginal effort into sustaining the "we are treating security seriously" message.

      In a way, the very existence of those bug bounty programs in large companies is evidence they don't see a reason to treat vulnerabilities seriously enough to proactively find and fix them in-house.

      If security vulnerabilities would be anywhere serious as most commenters on-line seem to think, companies would pay hundreds of thousands for serious vulnerabilities, just to save a day before they get hit by them - on top of spending millions in-house to try and stay ahead of the attackers.

      But they don't. Because most exploits are inconsequential and/or aren't being exploited much.

    There is an internal library at Microsoft that reliably avoids all these JWT problems - Microsoft Identity Service Essentials (MISE). Adopting MISE and upgrading to the latest versions of it have been part of the Secure Future Initiative (SFI) that can be read about in the news of previous years. Unfortunately it sounds like the service team intentionally deferred the compliance alerts they will have received.
    • jhfdbkofdchk 1 hour ago
      There is so much work to do for SFI that is still being ignored. The only way that some of these services will update is by being the target of the red team, security researcher, or threat actor.
      • verst 1 hour ago
        And all of that is definitely happening.

        That being said, just last night I observed that the identity team is now opening up agent-assisted PRs against individual service team repos to force MISE adoption and upgrade to the latest version and best practices. I think that's a great thing because many individual service teams simply lack the bandwidth or knowledge. Prior to GenAI availability I wasted many cycles on this kind of work. While GenAI made it easier - internal source documentation still does not unambiguously address every use case. So having the identity team drive this now with the help of agent sessions initiated by them is great.

      You assume that whoever was responsible for the implementation of this feature cares in the slightest beyond “it seems to work”.
      • TeMPOraL 17 minutes ago
        You assume there is any actual reason to care more than that in this case.
      • lurk2 49 minutes ago
        His comment didn’t assume that at all.

        Physical security vendors usually stop exactly there. I can't count how many vendors responsible for badge systems shut off the Windows Firewall just because it’s easier than adding a rule.
      • ToucanLoucan 48 minutes ago
        Honestly that series of blog posts that came across here semi-recently about what an utter disaster the Azure team is (through little fault of their own, mind you), combined with a lot of things I've read about the development behind Halo Infinite, have convinced me Microsoft is to avoided whenever possible. It's not even that they're too big to care, though that is an issue. It's that organizationally they are SO reliant on short-term contractors and junior devs plugging away with copilot, along with an ever more exhausted group of seniors who actually work for them but are continually disempowered, that I think it's safe to say anything they manage to ship is a minor miracle if it works at all, and it's certainly not going to have any guarantee at all of solid software engineering fundamentals.

        And to be clear, this is not an issue with them using contractors, overseas or otherwise, or with their senior dev staff, or even with AI really. It's an issue with them organizationally being so incredibly penny-pinching, and so dedicated to shipping new shit versus fixing anything long term, constantly chasing new revenue and letting their existing offerings rot.

        If a Microsoft product is good nowadays, it is literally a miracle.

    > {"alg":"none","typ":"JWT"}

    I don't know how this ever became a thing that was allowed into the spec and then picked from the spec and implemented in various implementations.

    • flowerlad 50 minutes ago
      It should be retroactively removed the spec, and all implementations should remove the "none" algorithm. It is a huge security hole.
    • pixl97 40 minutes ago
      Yea, and it was a big issue years ago. I can't believe there is any modern implementation that has it.... or another way to put this is, how old is this damned implementation they are using?

    wow I am so surprised to hear once again how JWTs are terrible

    https://www.howmanydayssinceajwtalgnonevuln.com/

    • fabian2k 2 hours ago
      Someone not verifying the signature at all is not a mistake where you can blame the JWT spec itself.
      • meindnoch 1 hour ago
        They did verify the signature, and it was correct according to the "none" algorithm.
        • fabian2k 1 hour ago
          Argh, I missed that it actually uses the "none" algorithm. Yeah, the existence of that option is extremely dumb and it shouldn't be possible to use that. I misread the post and thought it was a regular JWT, but they simply didn't validate it.

      • buckle8017 1 hour ago
        JWT is complicated.

        Complexity is a spec failure in security issues.

        It's that simple.

    • talon8635 1 hour ago
      Does this extend to OIDC? I’m not knowledgeable on the topic but it uses JWT right? Is it also prone to poor implementation? If you just error on alg=none does that solve it?
    • Perz1val 2 hours ago
      Idk if that's not too much of an oversimplification, maybe more like JWTs are an indicator/enabler of architecture level bugs?
    • skhameneh 1 hour ago
      Other commenters are suggesting you can’t blame the spec for end implementation mistakes, except that’s one of the many issues - JWT being so error-prone is a problem.

      I use JWT just for handling of tokens, because it’s so well supported, but I won’t use it for anything more than token storage _because_ it is so vulnerable to mistakes.

      The fact that mistakes are so easy to make is indicative of poor design in the spec itself.

    I am the last person to judge someone for using AI to help them write a blog post, but what I wonder is: Do people not read what the AI produces before putting their name on it, or is the AI writing style not obvious to some people, or do they just not care that it's obviously AI and bad style?

    • t-writescode 2 hours ago
      That.. looks like a normal sentence to me, and very probably one of the ones Microsoft required they add.

      Did you give the article a once-over beyond that? It’s one of the decidedly not-AI lines.

      • 0x_rs 2 hours ago
        It's not a "normal" sentence and is quite clearly produced by an LLM, it's a typical Claudeism so probably that. The entire post is also flagged by Pangram, so OP is correct.
      • ltbarcly3 2 hours ago
        Prefixing saying something with "Two quick notes first" is extremely common AI meta commentary. You may be right that it is something Microsoft insisted he put at the top, which would also explain the weird style.

      Explain why easily 40% of HN posts are about AI, and when people actually _use_ AI for this task, they are vilified for (allegedly) using it.
      • ltbarcly3 19 minutes ago
        I pasted the thread into ChatGPT and here is what it would like to tell you:

        The comment explicitly says, “I am the last person to judge someone for using AI to help them write a blog post.” The criticism is about the quality of the published prose and whether anyone reviewed it before putting their name on it.

        You can dispute whether that sentence is bad or whether it indicates AI authorship. But “why criticize unedited AI prose when HN talks about AI so much?” doesn’t identify a contradiction. Discussing a technology doesn’t imply endorsing every use of it, and criticizing its output isn’t the same as vilifying someone for using it.
