"There was no meaningful organization scoping, no tenant isolation, and no permission check preventing a low-privilege user from accessing other organizations' records."

Let me guess though. They are SOC2 and ISO compliant right ?

Well that’s pretty damning.

I keep getting emails with the content like: "I found a critical bypass vulnerability in your app what is the appropriate channel to disclose it, and do you have a bounty program?"

I tried engaging and replying to them, and it inevitably turns into: "Yeah, we don't actually have the vulnerability, but you are totally vulnerable, just let us do a security audit for you".

I have a pre-written reply for these kinds of messages now.

From the looks of it, they actually asked for a way to report.

They could sell the next one to an adversary for a lot more money if they're going to act like that.

Yes, there are also many other lucrative illegal activities.

Isn't it also illegal to withhold knowledge of a vulnerability for payment? It sounds like it should fall under some variety of blackmail.

Finally the AI security startup hustlers will keep the other tech startup hustlers in line. Maybe the era of devastating leaks and total disregard for user privacy will come to an end (doubtful).

a16z = "Andreessen Horowitz", for those not in the know. (The acronym is not expanded in the article. EDIT: OP has fixed the article.)

Would it be possible to stop using aXXb nomenclature within the titles? Some of us aren't hip enough to know what all of them mean.

Their website is literally a16z.com... you'd rather say Andreessen-Horowitz, which is just as arbitrary as a16z? They're one of the top VC firms on the planet -- exceedingly relevant for the HN audience.

Yes. I know Andreessen-Horowitz and I don’t know a16z. Reading the title i thought it will be about the cryptography serialisation specification. Turns out i was mixing it up with ASN.1.

> Their website is literally a16z.com

I hear now. Before this if pressed i would have guessed that they probably have a website indeed. If you would have twisted my arm my guess would have been andersenhorovitz.com (yup, with the typos. I learned the correct spelling today from your comment.)

> exceedingly relevant for the HN audience

We contain multitudes.

I'll be honest - I was thinking authorization (a11n?) - so I didn't read it closely enough. But despite that, and being on HN from almost the beginning (with a different account I lost the password to), I still didn't know what a16z was, though I do recognize Andreessen-Horowitz.

Opposite for me, I've seen a16z tons of time on HN, and also the domain where sometimes, but the full name would have meant nothing to me.

I didn't either. This is an ancient debate that can never be resolved completely, though — because the articles that HN submissions point to don't follow a style guide and there are always assumptions about audience priors. Best to just resolve it and move on.
