@herrmann1001 congrats! love to see community acknowledge and support Proxmark development in such a big way
@moyix i love to watch codex plan out projects with like multi-month roadmaps. never stops being funny.
Hacking Google with A.I. for $500,000 brutecat.com/r/hacking-goog…
This guy sucks. At my first Pwn2Own he asked me over and over if it was my first CVE. I said no but he kept insisting, in front of everyone, he’d never seen my name credited before. Turns out he was confusing me with another woman in infosec. In charge of security research engagement for MSRC btw
@dreadnode @Dr_Machinavelli @shncldwll ooh, this looks like a fun one!
@eliebakouch thank you for this wonderful thread!
@yacineMTB ooh very dope, looooove pufferlib. haven't dove into Warp stuff much, will have to play with it
i got paid to overflow a buffer on a nintendo 64 (arbitrary code execution on mario golf via transfer pak)
we got early access to Opus 4.8 and used it to hack a Nintendo 64 game you forgot about. here's what it didn't find: 1/
@Kypherion @DefaultDNB i always encourage people to try out both when it comes to relatively niche areas of work (they’ve both been good for me though)
@kipperrii really enjoy the extra thinking, conversation, and choose-your-own-adventure that 4.8 does on hard problems. very fun to work with.
@caseyjohnellis @mattjay this is dope, good stuff!
Inspired by Mythos finding 20-year old bugs in open source projects, we pointed Opus 4.8 at an esteemed 20 year old closed source target: 1999 Mario Golf on N64
we got early access to Opus 4.8 and used it to hack a Nintendo 64 game you forgot about. here's what it didn't find: 1/
@thedawgyg been using new claude 4.8 for a hot minute and actually really been enjoying it a lot more than 4.7
@b1ack0wl there are a couple more good meme vulns in the pipeline i can’t wait to post about too!
@scaling01 was using it in early access, big fan of some of the changes. feels like a step in the right direction
