This reverse engineering work led its way to a fix in Chrome (subsequently Electron), with credit given back to me! Very cool to see, and happy to help the macOS ecosystem. I hope macOS fixes this huge issue soon. chromium-review.googlesource…
Everything is open source if you try hard enough. (Trying to find the source of a pathological performance issue stemming from AppKit only on macOS 26. I'm pretty sure it's a macOS 26 bug but given this is shipping, I need to find a workaround).
I really wish Apple would just make the source of their frameworks available (even under a non-OSS license that doesn't allow any reuse), just so that app developers can understand how certain logic interacts with the system.

when building ai products, the key is having some reliable signal about what is working and what is not. whether that signal comes from evals, user feedback, your own taste, performance metrics, or just gut feel does not really matter as long as it is giving you actionable information about where to focus your efforts.
the mistake is either having no signal at all (just building blindly) or getting caught up in the methodology of the signal rather than its utility. a formal eval that tells you nothing useful is worse than informal feedback that clearly points to real problems

A fix from Google was released today. Part of the issue was due to my misunderstanding based on previous reports.
Big thanks to chromium team for the quick resolve
I hope everyone had some fun, and apologies to the triagers on HackerOne XD

Imagine not having had any food to give your kids for 10 days.
I swear to God, this what exactly happened:
I woke up today morning and found a missed call on my phone coming from a widow with a number of orphan children living next door.
I called her back and asked her what she wanted.
She said: “I need some flour. Me and my children have been sleeping without food for 10 days.”
I replied: “Unfortunately, me and my children have nothing to eat for more than 10 days.”

We did it! We tested 300 Bay Area foods for plastic chemicals. We found some interesting surprises.
Top 5 findings in our test results:
1. Our tests found plastic chemicals in 86% of all foods, with phthalates in 73% of the tested products and bisphenols in 22%. It's everywhere.
2. We detected phthalates in most baby foods and prenatal vitamins.
3. Hot foods which spend 45 minutes in takeout containers have 34% higher levels of plastic chemicals than the same dishes tested directly from the restaurant.
4. The 1950s Army rations we tested contained surprisingly high levels of plastic chemicals.
5. Almost every single one of the foods we tested are within both US FDA and EU EFSA regulations.
Check out our full results below.

Pass-the-{token} attacks are still very much relevant.
Tokens may change: Cookie, NT Hash, Kerberos ticket, MFA token, ...
However, the problem is not in the "token" but in the "pass".
We need a solutions to make tokens stay put, such as device and channel binding.
Microsoft has detected a 111% year-over-year increase in token replay attacks, and incidents are continuing to grow. msft.it/6011lSgZ7

I love crossover bugs that go between web/mobile/native because there's so much strange interactions that occur and a lot can go wrong - this research was another result of this!

We recently found a vulnerability affecting Hyundai and Genesis vehicles where we could remotely control the locks, engine, horn, headlights, and trunk of vehicles made after 2012.
To explain how it worked and how we found it, we have @_specters_ as our mock car thief:

I would like to use this opportunity to thank those who made this possible. Thank you. ❤️
