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.

I don't want to do the easy finger-pointing and scapegoating but honestly, what should happen to the Context.ai employee that thought it was a good idea to play games in their work machine and, on top of that, install cheats which are by definition of dubious provenance? I know defense in depth, security layers etc etc but there is also some personal responsibility at play here. We can chalk up the Vercel's employee mistake to a defense in depth failure that's on the whole company and management, but installing a cheat...

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.

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.

A frigging Roblox cheat...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...

Very ironically, they seem to have upped their game. Trying to read TFA on an older version of firefox gives me the lovely message:Failed to verify your browser Code 11 Vercel Security Checkpoint, arn1::1776759703-rtDgRAtRyXvjD4IoU4RbqvkGmvQQCP7HGah.

> 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.

I'm getting a "failed to verify your browser" error on this article

Something has gone screwy with the timestamps on this page... They're saying they were posted "in 8 hours", "in a day", then the last one is "an hour ago"

Context.ai seems like it was the SPOF. By definition it has a lot of your data, and they didn’t secure it properly.

Feels like the bigger issue here is how much implicit trust we’re starting to place in these AI-integrated workflows.Tools that sit in the middle (like Context.ai) end up becoming a pretty large attack surface without feeling like one.

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.

I don't see storing non-sensitive environment variables unencrypted as the main issue here. Sure at vercels scale, encryption at rest for any data would add some better baseline, but i see this article as two major user interface fails more than anything else. Oauth dialogs are just pathetic, they are years behind what is required and what UX research knows how to do things, none of the companies invested any amount of resources into it after it just worked well enough not to make most users churn. The env var problem is also ridiculous, you can only update, not see and check values in the interface if they are encrypted for most providers i know, that leads to really annoying UX and is the reason they are not marked as sensitive by default and opt out. Even if you could unlock them to edit, no one will enter their password again as that is too much hassle, meaning we need a way to read and edit encrypted env vars in the interface where they are created but not have more in the way than a passkey dialog. Its doable but afaik no provider would go the extra mile to get to this UX.(Of course there are tons of other red flags not looked at in the article, eg. how does an employees machine get access to production systems and from there access to customers connected with oauth and how does the attacker get to env vars from a google workspace account)

good article, these AI products are crazy supply chain risks.

Convenience is our Achilles heel, as a society.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.

This article is LLM authored and full of hallucinations. "Let that sink in for a second."
