alt Hacker NewsIt sounds like what makes the pipeline in the article effective is the second stage, which takes in the vulnerability reports produced by the first level and confirms or rejects them. The article doesn't say what the rejection rate is there.
I don't think the spammers would think to write the second layer, they would most likely pipe the first layer (a more naive version of it too, probably) directly to the issue feed.
There are at least three differences:
* Carlini's team used new frontier models that have gotten materially better at finding vulnerabilities (talk to vulnerability researchers outside the frontier labs, they'll echo that). Stenberg was getting random slop from people using random models.
* Carlini's process is iterated exhaustively over the whole codebase; he's not starting with a repo and just saying "find me an awesome bug" and taking that and only that forward in the process.
* And then yes, Carlini is qualifying the first-pass findings with a second pass.
