It is kinda hilarious when you realise that all Cyber AI models were trained on Bugtraq emails.
Omg I found a copy of the original memory_limit advisory. marc.info/?l=bugtraq&m=10898…

Been a part of a PSIRT team is likely one of the most stressful, difficult and badly recognized jobs in infosec. It requires so many varied talents. Huge respect for the VERY, VERY few folks that do it properly. Now, for the many others: I honestly struggle to differentiate your behavior from a scammer. Fake skills, fake caring, fake relationship. How some large companies have PSIRT leaders that after 20+ years in the industry don't even know basic terminology is beyond me! Folks can probably guess that I somehow am involved in dealing with reporting bugs again... after so many years, nothing changed!

a friend of my cat has a neighbor who heard a rumor that OpenAI broke hybrid ML-KEM+ECC which would explain why CNSA went for non-hybrid and I dont wanna speculate but AES is probably at risk too

Cool paper from Anthropic on the zeros of Zeta, including a Lean proof. How about proving 0 = 1 using Lean ? See our @defcon talk and proof: github.com/endrazine/lean-cv…
We asked an unreleased research version of Claude to take a stab at the Riemann hypothesis.
It didn’t solve it, but it did make strides on a related problem: it increased the lower bound for the fraction of zeros of the Riemann zeta function that satisfy the hypothesis from 41.6% to 67.2%.
