Still no email blast from Vercel alerting users, which is concerning.
On the one hand, I get that it's a Sunday, and the CEO can't just write a mass email without approval from legal or other comms teams.
But on the other hand... It's Sunday. Unless you're tuned-in to social media over the weekend, your main provider could be undergoing a meltdown while you are completely unaware. Many higher-up folks check company email over the weekend, but if they're traveling or relaxing, social media might be the furthest thing from their mind. It really bites that this is the only way to get critical information.
They can be brought in to do their job on a Sunday for an event of this relevance. They can always take next Friday off or something.
If the attacker is moving with "surprising velocity," every hour of delay on an email blast is another hour the attacker has to use those potentially stolen secrets against downstream infrastructure. Using Twitter/X as a primary disclosure channel for a "sophisticated" breach is amateur hour. If legal is the bottleneck for a mass email during an active compromise, then your incident response plan is fundamentally broken.
Better to report 100% known things quickly. People can figure it out with near zero effort, and it reduces one tiny bit of potential liability in the ops shitstorm they’re going through.
This feels like a natural consequence of the direction web development has been going for the last decade, where it's normalised to wire up many third party solutions together rather than building from more stable foundations. So many moving parts, so many potential points of failure, and as this incident has shown, you are only as secure as your weakest link. Putting your business in the hands of a third party AI tool (which is surely vibe-coded) carries risks.
Is this the direction we want to continue in? Is it really necessary? How much more complex do things need to be before we course-correct?
We need a different hosting model.
There really isn't an option here, IMO.
1. Somebody does it
2. You do it
Much happier doing it myself tbh.
And my own kernel. Can't trust some shit written by a Finnish dude 30 years ago.
And my own UEFI firmware. Definitely can't trust some shit written by my hardware vendor ever.
The AI maximalists would argue that the only way is through more AI. Vibe code the app, then ask an LLM to security review it, then vibe code the security fixes, then ask the LLM to review the fixes and app again, rinse and repeat in an endless loop. Same with regressions, performance, features, etc. stick the LLM in endless loops for every vertical you care about.
Pointing to failed experiments like the browser or compiler ones somehow don’t seem to deter AI maximalists. They would simply claim they needed better models/skills/harness/tools/etc. the goalpost is always one foot away.
You can write good and bad code with and without AI, on a managed service, self-hosted, or something in between.
And the comment I was replying to said something about not trusting something written in Akron, OH 2 years ago, which makes no sense and is barely an argument, and I was mostly pointing out how silly that comment sounds.
Regarding the unix philosophy argument, comparing it to AI tools just doesn't make any sense. If you look at what the philosophy is, it's obvious that it doesn't just boil down to "use many small tools" or "use many dependencies", it's so different that it not even wrong [0].
In their Unix paper of 1974, Ritchie and Thompson quote the following design considerations:
- Make it easy to write, test, and run programs.
- Interactive use instead of batch processing.
- Economy and elegance of design due to size constraints ("salvation through suffering").
- Self-supporting system: all Unix software is maintained under Unix.
In what way does that correspond to "use dependencies" or "use AI tools"? This was then formalised later to
- Write programs that do one thing and do it well.
- Write programs to work together.
- Write programs to handle text streams, because that is a universal interface.
This has absolutely nothing in common with pulling in thousands of dependences or using hundreds of third party services.
Then there is the argument that "AI is just a higher level compiler". That is akin to me saying that "AI is just a higher level musical instrument" except it's not, because it functions completely differently to musical instruments and people operate them in a completely different way. The argument seems to be that since both of them produce music, in the same way both a compiler and LLM generate "code", they are equivalent. The overarching argument is that only outputs matter, except when they don't because the LLM produces flawed outputs, so really it's just that the outputs are equivalent in the abstract, if you ignore the concrete real-world reality. Using that same argument, Spotify is a musical instrument because it outputs music, and hey look, my guitar also outputs music!
It’s interesting how they all use LLMs to write their Reddit posts, too. Some of them could have drawn in some people if they took 5 minutes to type an announcement post in their own words, but they all have the same LLM style announcement post, too. I wonder if they’re conversing with the LLM and it told them to post it to Reddit for traction?

Protection money from Vercel.
"Pay us 10% of revenue or we switch to generating Netlify code."
So I told something like, "don't use anything node at all", and it immediately rewrote it as a Python backend, and it volunteered that it was minimizing dependencies in how it did that.
[1] only vibe coding as an exercise for a throwaway artifact; I'm not endorsing vibe coding
I've heard others had similar results with .NET/C#
You don't have to live like this.
I once made a golang multi-person pomodoro app by vibe coding with gemini 3.1 pro (when it had first launched first day) and I asked it to basically only have one outside dependency of gorrilla websockets and everything else from standard library and then I deployed it to hugging face spaces for free.
I definitely recommend golang as a language if you wish to vibe code. Some people recommend rust but Golang compiles fast, its cross compilation and portable and is really awesome with its standard library
(Anecdotally I also feel like there is some chances that the models are being diluted cuz like this thing then has become my benchmark test and others have performed somewhat worse or not the same as this to be honest and its only been a few days since I am now using hackernews less frequently and I am/was already seeing suspicions like these about claude and other models on the front page iirc. I don't know enough about claude opus 4.7 but I just read simon's comment on it, so it would be cool if someone can give me a gist of what is happening for the past few days.)
Switch to vibe coding Rust backends and freeze your supply chain.
Super strong types. Immaculate error handling. Clear and easy to read code. Rock solid performance. Minimal dependencies.
Vibe code Rust for web work. You don't even need to know Rust. You'll osmose it over a few months using it. It's not hard at all. The "Rust is hard" memes are bullshit, and the "difficult to refactor" was (1) never true and (2) not even applicable with tools like Claude Code.
Edit: people hate this (-3), but it's where the alpha is. Don't blindly dismiss this. Serializing business logic to Rust is a smart move. The language is very clean, easy to read, handles errors in a first class fashion, and fast. If the code compiles, then 50% of your error classes are already dealt with.
Python, Typescript, and Go are less satisfactory on one or more of these dimensions. If you generate code, generate Rust.
But you're also correct in that Rust is actually possible to write in a more high level way, especially for web where you have very little shared state and the state that is shared can just be wrapped in Arc<> and put in the web frameworks context. It's actually dead easy to spin up web services in Rust, and they have a great set of ORM's if thats your vibe too. Rust is expressive enough to make schema-as-code work well.
On the dependencies, if you're concerned about the possibility of future supply chain attacks (because Rust doesn't have a history like Node) you can vendor your deps and bypass future problems. `cargo vendor` and you're done, Node has no such ergonomic path to vendoring, which imo is a better solution than anything else besides maybe Go (another great option for web services!). Saying "don't use deps" doesn't work for any other language other than something like Go (and you can run `go vendor` as well).
But yeah, in today's economy where compute and especially memory is becoming more constrained thanks to AI, I really like the peace of mind knowing my unoptimised high level Rust web services run with minimal memory and compute requirements, and further optimisation doesn't require a rewrite to a different language.
Idk mate, I used to be a big Rust hater but once I gave the language a serious try I find it more pleasant to write compared to both Typescript and Go. And it's very amiable to AI if that's your vibe(coding), since the static guarantees of the type system make it easier for AI to generate correct code, and the diagnostics messages allow it to reroute it's course during the session.
However it is less clear on how to do this, people mostly take the easiest path.

The internet does that but it feels different with this
That's a funny way of saying "race to the bottom."
> The internet does that but it feels different with this
How does "the internet do that?" What force on the internet naturally brings about mediocrity? Or have we confused rapacious and monopolistic corporations with the internet at large?
Stack exchange. Google.
It is true that "more diversity in code" probably means less turnkey spray-and-pray compromises, sure. Probably.
It also means that the models themselves become targets. If your models start building the same generated code with the same vulnerability, how're you gonna patch that?
This situation is pretty funny to me. Some of my friends who arent technical tried vibe coding and showed me what they built and asked for feedback
I noticed they were using Supabase by default, pointed out that their database was completely open with no RLS
So I told them not to use Supabase in that way, and they asked the AI (various diff LLMs) to fix it. One example prompt I saw was: please remove Supabase because of the insecure data access and make a proper secure way.
Keep in mind, these ppl dont have a technical background and do not know what supabase or node or python is. They let the llm install docker, install node, etc and just hit approve on "Do you want to continue? bash(brew install ..)"
Whats interesting is that this happened multiple times with different AI models. Instead of fixing the problem the way a developer normally would like moving the database logic to the server or creating proper API endpoints it tried to recreate an emulation of Supabase, specifically PostgREST in a much worse and less secure way.
The result was an API endpoint that looked like: /api/query?q=SELECT * FROM table WHERE x
In one example GLM later bolted on a huge "security" regular expression that blocked , admin, updateadmin, ^delete* lol
That lack of diversity also makes patches more universal, and the surface area more limited.
These libraries/frameworks are not insecure because of bad design and dependency bloat. No! It's because a mythical LLM is so powerful that it's impossible to defend against! There was nothing that could be done.
Something happened, we won't say what, but it was severe enough to notify law enforcement. What floors me is the only actionable advice is to "review environment variables". What should a customer even do with that advice? Make sure the variable are still there? How would you know if any of them were exposed or leaked?
The advice should be to IMMEDIATELY rotate all passwords, access tokens, and any sensitive information shared with Vercel. And then begin to audit access logs, customer data, etc, for unusual activity.
The only reason to dramatically overpay for the hosting resources they provide is because you expect them to expertly manage security and stability.
I know there is a huge fog of uncertainly in the early stages of an incident, but it spooks me how intentionally vague they seem to be here about what happened and who has been impacted.
> Environment variables marked as "sensitive" in Vercel are stored in a manner that prevents them from being read, and we currently do not have evidence that those values were accessed. However, if any of your environment variables contain secrets (API keys, tokens, database credentials, signing keys) that were not marked as sensitive, those values should be treated as potentially exposed and rotated as a priority.

So they are harder to introspect and review once set.
It’s probably good practice to put non-secret-material in non-sensitive variables.
(Pure speculation, I’ve never used Vercel)
There are cases where I want env variables to be considered non-secure and fine to be read later, I have one in a current project that defines the email address used as the From address for automated emails for example.
In my opinion the lack of security should be opt-in rather than opt-out though. Meaning it should be considered secure by default with an option to make it readable.
Oh and the owner likes to proudly remind people about his work on Google AMP, a product that has done major damage to the open web.
This is who they are: a bunch of incompetent engineers that play with pension funds + gulf money.
The Oracle that published an announcement that said "we didn't get hacked" when the hackers had private customer info?
The Oracle that does not allow you to do any security testing on their software unless you use one of their approved vendors?
The Oracle that one of my customers uses where they have to turn off the HR portal for 2 weeks before annual performance evaluations because there is no way to prevent people from seeing things?
The only reason Oracle isn't having nightmarish security problems published every other week is because they threaten to sue anyone that does find an issue.
Oracle is a joke in every conceivable way and I despise them on a personal level.
Google in particular has been staggeringly good, and don't sleep on IBM when they Actually Care.
This and because it's so convenient to click some buttons and have your application running. I've stopped being lazy, though. Moved everything from Render to linode. I was paying render $50+/month. Now I'm paying $3-5.
I would never use one of those hosting providers again.
Does Vercel do the same?
The point is, I used to just throw everything up on a PaaS. Heroku/Render, etc. and pay way more than I needed to, even if I had 0 users, lol.
The only possibility for that not being a reasonable starting point is if they think the malicious actors still have access and will just exfiltrate rotated secrets as well. Otherwise this is deflection in an attempt to salvage credibility.
While a different kind of incident (in hindsight), the other week Webflow had a serious operational incident.
Sites across the globe going down (no clue if all or just a part of them). They posted plenty of messages, I think for about 12 hours, but mostly with the same content/message: "working on fixing this with an upstream provider" (paraphrased). No meaningful info about what was the actual problem or impact.
Only the next day did somebody write about what happened. Essentially a database running out of storage space. How that became a single point of failure, to at least plenty of customers: no clue. Sounds like bad architecture to me though. But what personally rubbed me the wrong way most of all, was the insistence on their "dashboard" having indicated anything wrong with their database deployment, as it allegedly had misrepresented the used/allocated storage. I don't who this upstream service provider of Webflow is, but I know plenty about server maintenance.
Either that upstream provider didn't provide a crucial metric (on-disk storage use) on their "dashboard", or Webflow was throwing this provider under the bus for what may have been their own ignorant/incompetent database server management. I guess it all depends to which extend this database was a managed service or something Webflow had more direct control over. Either way, with any clue about the provider or service missing from their post-mortem, customers can only guess as to who was to blame for the outage.
I have a feeling that we probably aren't the only customer they lost over this. Which in our case would probably not have happened, if they had communicated things in a different way. For context: I personally would never need nor recommend something like Webflow, but I do understand why it might be the right fit for people in a different position. That is, as long as it doesn't break down like it did. I still can't quite wrap my head around that apparent single point of failure for a company the size of Webflow though.

I’m no security engineer, but this is flatly unacceptable, right? This feels like Vercel is covering its own ass in favor of helping its customers understand the impact of this incident.
Clicking the Vercel logo at the top left of the page hard crashes my Chrome app. Like, immediate crash.
What an interesting bug.
I find it fun we're all reading a story how Vercel likely is compromised somehow, and managed to reproduce a crash on their webpage, so now we all give it a try. Surely could never backfire :)

if it's not marked as sensitive (because it is not sensitive) there is no reason to roll them. if you must roll a insensitive env var it should've been sensitive in the first place, no?
I can imagine the reason why an env variable would be sensitive, but need to be re-read at some point. But overwhelmingly it makes sense for the default to be set, and never access again (i.e. Fly env values, GCP secret manager etc)
I feel for the team; security incidents suck. I know they are working hard, I hope they start to communicate more openly and transparently.
