Replying to @k0zmer
@k0zmer @z9frme and myself made a proof-of-concept (POC) exploit for the recently released log4shell vulnerability (CVE-2021-44228).
We also made a vulnerable application to test payloads on and play with. All of this can be found on the following repo:
github.com/kozmer/log4j-shel…
Lost stealmybitcoin.com by ~1h. We'd designed the winner's chain (PS(id) cookie leak → forged pDestructor to system()). The miss: display_errors=On made us assume memory_limit=-1. It was 128M. And we skipped the fix's test showing the 500× amplifier. gg @killa

Formal verification is practical now, at the instruction level. You can literally find every bug in a systematic way
And it's not just memory safety. Specs like ungzip(gzip(·)) = · work. Or any other property like data races, crash consistency, auth, etc
More coming soon :)
Audited claims that PHP 8.5.12's fix for CVE-2026-109618/109619 is incomplete. The residue is real, but the RCE needs attacker PHP and /proc/self/mem writes, nothing like the data-only trigger that got the originals KEV'd. Patch anyway.

I believe @yeswehack marked my submission as RTFS, but I think they are mistaken what can I do?

Wow. “Responsible disclosure” hitting math community now 🙃
We’re working with an independent advisory group of mathematicians to help OpenAI responsibly share advances in AI and mathematics.
The group will advise on how we assess and communicate new mathematical results, uphold academic and professional standards, and build tools that support mathematical research and learning.
Through this work, we want mathematicians to be at the center of shaping how AI supports mathematical understanding and how its benefits reach the wider community.

I hate this. I hate that people, even when slopping, don't even think about how it works. This has to end poorly and I don't see how an increase in "intelligence" is going to save you from the results of blind feature lust
I am done with this shit. It is over. The state of engineering right now is horrible. It has been half a month since I started a new role at a big company. Nobody knows anything here. The specs, code, tests, PRDs, tickets, resolution of those tickets, reports, etc., everything is made by Claude Code. Nobody on my team likes this. They are being forced to ship as much as they can. I have heard multiple times from higher management that pushing code is not a bottleneck, so why are we slow? People are working 12 to 13 hours a day just to press enter. Nobody is reading anything. Humans in corporate are doing nothing on their own. Everyone, literally everyone, from an L1 to an L7 engineer here is doing the same thing. Talk to Claude. There is no sense of victory. Nobody is resolving bugs. In reality, nobody is thinking anymore. Everything is done by LLMs. It is so soul-sucking. I would not mind it, to be honest, if we were at least given the time to check out the code and see what is going where. But no, the goal is to just ship. No matter what happens.
btw, this is exactly why the openai disclosure felt threatening to us.
when a ciso starts the conversation angry, of course researchers panic. something like this CFAA can be invoked, authorization boundaries can be disputed, and suddenly you’re talking to lawyers.
did we cross a boundary? anyone who used codex on cloud can tell its harmless what we did. we deliberately did not download sensitive internal information, we proved repo access with a harmless pr and stopped.
a ciso absolutely should ask what happened, ask us to stop, preserve logs, investigate, and verify whether anything sensitive was accessed, that’s indeed their job.
but once you establish that this was good-faith research, responsibly disclosed, with deliberate effort to minimize access, continuing to treat the researcher like an adversary achieves what exactly?
if the anger is because the bug is embarrassing, it doesn’t need to be. serious vulnerabilities can become great security stories, google does this all the time.
if it’s about the boundary, investigate it. establish what happened. then move forward if it’s responsibly done
researchers should leave responsible disclosure thinking “i’m glad i told them” not “i need a lawyer.”
this was me few years back, the pain of approaching a new target and writing an n-day exploit used to be a lot. i would spend days just understanding all the new things the target had implemented(like the v8 sandbox, windows exp here)then more days figuring out everything else and improvising around it.
it was literal grunt work, but it was beautiful, time would just disappear, you had a clear goal, you got feedback at every step, and you kept hillclimbing until you got there. i had some of the most fun in my life doing this kind of work.
unfortunately, that is changing now, i don't need to spend my time on this, this is all just largely automated.

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.
Is it normal for @yeswehack to mark a report as duplicate when no matching bug appears in program activity?
I reported the issue immediately, it was fixed the next day while still in triage, and I can’t find a matching vulnerability.
Can I request a review?

It's sad when one of the coolest bugs you found becomes a duplicate 😆
