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.)

We contain multitudes.
Well that’s pretty damning.
The system is already pretty bad because vendors underinvest in security, and then to fix it, researchers have to volunteer their time to investigate with no guarantee of payment. If the vendor could force researchers to hand over findings for free, nobody would want to do security research except hobbyists having fun. They're basically signing up for hours of tedious forced labor to explain vulnerabilities to the vendor.
I wish there was legislation that allowed the government to fine vendors for security vulnerabilities like this where the amount scales based on how much user data they leaked. And it could function like other whistleblower systems where a researcher who spots a leak can report it to the government and collect 50%, or they can report it to the vendor and negotiate direct disclosure, but the vendor has to bid against the reward the researcher would get from the government.
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.
I get tons of these messages too and the ones that do include details are the kind of junk you get from free "website vulnerability scanners" that are a bunch of garbage that means nothing -- "missing headers" for things I didn't set on purpose, "information disclosure vulnerabilities" for things that are intentionally there, etc... You can put google.com into these things and get dozens of results.
Let me guess though. They are SOC2 and ISO compliant right ?
How do people find these vulnerabilities within the immense scope of the whole internet? Are they going around with some kind of generic API scanner that discovers APIs?
The vulnerability itself appears to be something anyone with mitmproxy would have spotted within minutes of looking at the platform; apparently, rotating object IDs worked everywhere in the app, and there was no meaningful authz.
It's interesting if AI systems can "spot" these, in the sense of autonomously exercising the application and "understanding" obvious failed authz check patterns. But it's a "hm, ok, sure" kind of interesting.
1. I didn't see mention of a bug bounty program giving limited authorization. How do independent researchers do this with legal safety? Especially when DoD is involved?
2. If a researcher discovered a vulnerability at a DoD contractor, and the contractor didn't seem to be resolving the problem, is there a DoD contact point that would be effective and safe for the researcher to report it?
