I believe this is inaccurate. Vercel env vars are all encrypted at rest (on their side). The 'sensitive' checkbox means you can't retrieve the value once it's set, which would have saved your ass in this case. Also, annoying to read an article like this without a single link to source material.
They said "encrypted at rest", which they almost certainly are.
If you spin up an EC2 instance with an ftp server and check the "Encrypt my EBS volume", all those files are 'encrypted at rest', but if your ftp password is 'admin/admin', your files will be exposed in plaintext quite quickly.
I think this is wrong about what “sensitive” means here. AFAIK, all Vercel env cars are encrypted. The sensitive checkbox means that a develop looking at the env var can’t see what value is stored there. It’s a write-only value. Only the app can see it, via an env var (which obviously can’t be encrypted in such a way that the app can’t see it, otherwise it’d be worthless). If you don’t check that box, you can view the value in the project UI. That’s reasonable for most config values. Imagine “DEFAULT_TIME_ZONE” or such. There’s nothing gained from hiding it, and it’d be a pain in the ass come troubleshooting time.
So sensitive doesn’t mean encrypted. It means the UI doesn’t show the dev what value’s stored there after they’ve updated it. Not sensitive means it’s still visible. And again, I presume this is only a UI thing, and both kinds are stored encrypted in the backend.
I don’t work for Vercel, but I’ve use them a bit. I’m sure there are valid reasons to dislike them, but this specific bit looks like a strawman.
According to the email I got from Vercel it was a limited subset of customers and I'm not one:
Initially, we identified a limited subset of customers whose Vercel credentials were compromised. We reached out to that subset and recommended that they rotate their credentials immediately.
At this time, we do not have reason to believe that your Vercel credentials or personal data have been compromised.
> How many developers do you think knew that checkbox existed? How many assumed their database credentials and API keys were encrypted by default?
If I don't see asterisks, I'm not hitting save on the field with a secret in it. Maybe they were setting them programmatically? They should definitely still be looking to pass some kind of a secret flag, though. This is a weird problem for a company like Vercel to have.
Do you ask a bridge engineer if they forgot to reinforce the supports when they built the bridge? Even when I didn't know about security this was a table stakes thing. People saving sensitive things in plaintext are upset that their poor practices came back to bite them. Now, at the risk of sounding like I'm victim blaming here, Vercel is also totally bearing some responsibility for this insanity. But come on. FAFO and all that.
This looks really really AI-generated even if the author did try to hide it by making some grammar elements improper. Idk if that diminishes it's accuracy though.
I don't know why you are downvoted. The article is AI blogspam, it doesn't have any more factual information than eg https://www.darkreading.com/application-security/vercel-empl... and is full of empty LLMisms. It's depressing people are willing to read this.
Clearly, Vercel should not have been compromised by this. I don't know who Context.ai is but I do know Vercel and I expected better from them. I also think we can expect to see a lot more stories like this.
And I thought it was bad when my son got compromised by a Roblox cheat, but they only they grabbed his Gamepass cookies and bought 4 Minecraft licenses, which MS quickly refunded...
We'll keep dangerous devices like the SuperBox in our homes, if it helps us get access to free movies and tv.
We'll use single-use plastics, even if we know they're bad for the environment, because they're just so damn easy.
We'll let AI run that thing for us, because it's just too easy.
A whole generation has grown up without knowing what it was like to infect your computer with AIDS trying to download an MP3, and it shows. That caution will come back, just at a terrible cost.

I think it's clear that some customers env vars got exposed, so that can only mean unencrypted, right?

You pretty much have to assume someone is going to put sensitive data in an input like this. Encryption by default is the only sensible choice.

Because a comment that just says it's AI generated provides no value to the readers. They could at least provide an alternative link like you did.
I didn't notice till I saw this comment and now I'm also confident it's significantly AI written.
Context.ai seems like it was the SPOF. By definition it has a lot of your data, and they didn’t secure it properly.
Clearly, Vercel should not have been compromised by this. I don't know who Context.ai is but I do know Vercel and I expected better from them. I also think we can expect to see a lot more stories like this.
A frigging Roblox cheat...

good article, these AI products are crazy supply chain risks.
Convenience is our Achilles heel, as a society.
