next time you're thinking about researching the linux kernel (@linuxfoundation), remember that someone on the receiving end of your report might talk about you like this:
in one of the threads, kernel maintainer "Peter Zijlstra" decides to call the ZDI team "monkeys"
there's a longer argument about how ZDI submits reports, whether they should include patches, and how fixes get tested. fair enough, have that discussion
but how does insulting the people reporting vulnerabilities help?
i thought the kernel's code of conduct was something everyone on these lists was expected to follow
sad to see people spoken to like this while trying to help improve linux security.

Bluetooth sync is supposed to import your contacts. But Joshua Foote (@BoredPentester) had a different idea, and it became a path to root on a Kenwood DNR infotainment unit. Amazing how much you can get from one of the less scary looking Bluetooth profiles, PBAP (phonebook access). #theSAS2026
Friends ask: “You’re a consultancy with no product, why STAR Labs?” Today’s my answer: 5 RCEs on Pixel 10 & 11, all patched by Google, from a team you could fit round 1 table. We don’t sell a box. We break the unbreakable and tell you how. 👇

Atrophy is a choice. Machines play chess better than we do, but we still play and reap many benefits from it. Let AI perform tasks, but never stop challenging your mind, or yourself.

One of mine and my team (once they update/correct the credits)🔥. You may want to patch 👀

BJJ is great for problem solvers.
Do it for a few years and you can spend the rest of your life solving problems. Things like: why can’t I look left today. Or, huh, I’m pretty sure I could use a pen yesterday.
Highly recommend it.
