already exists: https://joshua.hu/comparing-redos-detection-tools. `recheck` and `redos-detector` are definitely the best. there's even an eslint plugin for the latter: https://github.com/tjenkinson/eslint-plugin-redos-detector

Wow very cool, theyve now closed 150 bugs identified via ai assistance/static analysis!
For ref, here is the post from Joshua Rogers about their investigation into the tooling landscape which yielded those findings

I'm using them, but frankly only for things where my quality bar is lower. I've seen little evidence that anyone is routinely getting work that's comparable to competent humans, excepting incredibly recent work like Joshua Rodgers' [0]. And I'll note that even Joshua's work was mainly successful in identifying issues, but actually fixing them involved much more human intervention.

See Joshua's post for details: https://joshua.hu/llm-engineer-review-sast-security-ai-tools-pentester…
Tools included ZeroPath, Corgea and Almanax.

I did not read it, but this article from the contributor should contain more details: https://joshua.hu/llm-engineer-review-sast-security-ai-tools-pentester… (mentioned in https://mastodon.social/@bagder/115241413210606972).

This should probably link to the original blog post by Joshua Rogers:

I haven't read it yet, but later in the mastodon thread, stenberg says "this is [the contributor's] (long) blog post on his work: https://joshua.hu/llm-engineer-review-sast-security-ai-tools-pentester…

The linked blog post https://joshua.hu/llm-engineer-review-sast-security-ai-tools-pentester… shows that most of the used tools can be run in ci and comment on the PRs.

If something is found by Valgrind, we can reproduce it ourselves. Here we get private bug reports found by "his set of AI assisted tools".
The set seems to be:
https://joshua.hu/llm-engineer-review-sast-security-ai-tools-pentester…
So he likes ZeroPath. Does that get us any further? No, the regular subscription costs $200 and the free one-time version looks extremely limited and requires yet another login.
Also of course, all low hanging fruit that these tools detect will be found quickly in open source (provided that someone can afford a subscription), similar to the fact that oss-fuzz has diminishing returns.

there's a blog link https://joshua.hu/llm-engineer-review-sast-security-ai-tools-pentester… that has Products chapter
I guess mastodon link is simply a confirmation that bugs were indeed bugs, even with wrong code snippets?

that's still a huge waste of time and resources. Rather, Daniel has focused on promoting good use of AI that has yielded good results for curl: https://mastodon.social/@bagder/115241241075258997 https://joshua.hu/llm-engineer-review-sast-security-ai-tools-pentester…

Ultimately, one of the cameras in my iPhone 7 failed, and I replaced it with an SE3 - which was indistinguishable from the 7 - but another issue was patches.
With very little skill, I found I could duplicate this issue on my iPhone 7 running the latest supported version of iOS: https://joshua.hu/apple-ios-patched-unpatched-vulnerabilities

Okay, so anti AI people are just making shit up now. Got it.
According to Willy Tarreau[0] and Greg Kroah-Hartman[1], this trend has recently significantly reversed, at least form the reports they've been seeing on the Linux kernel. The creator of curl, Daniel Steinberg, before that broader transition, also found the reports generated by LLM-powered but more sophisticated vuln research tools useful[2] and the guy who actually ran those tools found "They have low false positive rates."[3]
Additionally, there was no mention in the talk by the guy who found the vuln discussed in the TFA of what the false positive rate was, or that he had to sift through the reports because it was mostly slop — or whether he was doing it out of courtesy. Additionally, he said he found only several hundred, iirc, not "thousands." All he said was:
"I have so many bugs in the Linux kernel that I can’t report because I haven’t validated them yet… I’m not going to send [the Linux kernel maintainers] potential slop, but this means I now have several hundred crashes that they haven’t seen because I haven’t had time to check them." (TFA)
He quite evidently didn't have to sift through thousands, or spend months, to find this one, either.
