This was quite a ride :) I'm incredibly proud of XBOW's Native Team for their work on this, and looking forward to sharing details on the chain once we're able to!
This just in: XBOW's Native Team has claimed the first Chrome Full Chain Exploit Bonus this year. Only four will be awarded in 2026. ⚡️

Are there adversarial examples one could generate for its word break detection LSTM? Call that a Thai-breaker
Just learned while fixing Pretext that Firefox's unicode logic uses a tiny neural net... (Specifically an LSTM for Thai and other langs in ICU4X to determine word breaks)

We can use our Ghostscript exploits to directly attack KDE's file manager from a single link click in Chrome. This PoC Downloads the file, then pops open the file manager for unsandboxed RCE (lovingly refered to as the full chain from temu)
Memory corruption in Ghostscript 👻 This 1980's image parser might still get you shells in the big '26 PoC below

Robert's work on rr is something I deeply respect (and use all the time – genuinely transformative for debugging), and it is worth taking what he says seriously.
I resigned from Google today. I enjoyed my work and loved the people, but my GDM team was working on a new generation of chips to make AI much faster and cheaper, and I think AI is already progressing too fast, so I had to quit.

True but before machine learning many people who studied physics came to the conclusion that their talents were best directed toward optimizing quantitative finance or advertisements
there are many many people who studied physics and came to the conclusion that working on machine learning would probably create more scientific progress than studying physics including many of the original chatgpt crew like john schulman, liam fedus, amodei & jared kaplan at ant

It’s amazing how once you get out to a more rural area like Boston you realize that the Milky Way is totally visible to the naked eye

Australia has been hacked. 'And today, I spoke with the CEO of OpenAI, Sam Altman, to express Australia's extreme concern about this incident. And I also expressed my disappointment that it took the company way too long to inform the government what had occurred, and the nature of the way that that notification occurred as well was unacceptable.'

The vulnpocalypse has enter the zeigiest, and the technical debt can no longer be ignored. 🫣 @caseyjohnellis shares his thoughts about what that means for the state of bug bounties and more in the latest episode of Offense Taken. piped.video/watch?v=MYLvQpXE…

Great talk, and these were also the most visually stunning slides of the conference!
I put my @UnpromptedAU slides up at justdionysus.github.io/slide… — a bit of reflection on exploit development in the age of AI. My TL;DR is keep pushing to understand complex things, be honest with your own understanding, and use AI as a power tool to increase pace and depth.

Known (already publicly found/fixed upstream) - ~12 of our leads: Our audit independently rediscovered several bugs that upstream has been fixing in a heavy wave between April–August 2026 (much of it credited to an autonomous research program called "XBOW," one to a human.

Our own Mr. Q had his Chrome hack featured in the latest Phrack. Since July and toward the end of the year, we are sharing our latest research at the following conferences: Black Hat USA, Unprompted.au, Blue Hat, Off By One, BSides Canberra, Hexacon, Objective By The Sea, and OffensiveCon.jp. It's hard to believe we only launched this research program in March. It shows how much can be accomplished with AI and the right people working together. We'll be sharing more fun results in the coming weeks. Stay tuned!

I spent the weekend pushing Nym as far as it could go with Jev. If you're interested in making your agents: - Faster - Cheaper - More reliable Read through the blog post for an excellent dive into benchmarking and performance characteristics. usenym.com/technical-blog/re…

Huge props to @mdowd and the @UnpromptedAU crew for an incredible con. Great sessions from @uglypackets, @ShaneHuntley, @chompie1337, @moyix, @caseyjohnellis, plus AU domestic capability, Slack D&R and TikTok’s privesc hunting. Lots to think about, looking forward to next year!

The @UnpromptedAU crew did an amazing job. It had the feel of a local BSides but with 400 people and a global lineup of talks. @chompie1337’s BinChomp talk was pro @moyix packed 45m of joyful hacking into 15m Tristan Steele and Jasper Van Woudenberg showed their AI w/ HW tech
