Sir @demishassabis has a mind for synthesis. His favorite book is about a grand theory of everything. His preferred philosophers are seen by some as opposites. His life's work ranges from board games to Nobel-winning science. We're grateful to have hosted Demis and his @GoogleDeepMind team at @sequoia AI Ascent last week for a fireside chat. He kindly gave us permission to share this, and you can watch the full video here: 00:00 Intro 00:38 The Common Thread 01:29 Games as AI Training 02:59 Startup Advice 1.0 04:39 Founding DeepMind 07:25 DeepMind and AGI 08:52 AI for Science 10:37 Biology Breakthroughs and Isomorphic 12:42 New Sciences 20:29 Philosophy

Introducing Praxis, an adversarial framework for discovering, controlling, and orchestrating computer-use agents running on endpoints. Announcement → originhq.com/blog/praxis-ann… Get Praxis → praxis.originhq.com

Natural language collapses meaning across layers. LLMs don’t just fail at instructions, they misinterpret intent, and they expose that unforgivably when we treat language like a protocol. In a short @originhq blog post, I break down semantic protocol confusion and what it means for agent safety. originhq.com/blog/semantic-p…

Yup transformernews.ai/p/claude-…

In this simple example, we show that Claude Code can read the iMessage database on the latest version of macOS, even with a leading EDR running on the system, illustrating the impact of an adversary who can remotely control the agent. We do this using Terminator, an internal research tool we built while studying the security implications of computer use agents. In this setup, the terminal application has previously been granted FDA, a subtle misconfiguration that effectively gives the agent access to unexpected context.

We believe that: 1. The potential economic upsides of the productivity boosts that Computer Use Agents offer incentivize us to provide them with more access to our computers to increase the amount of context they can have. 2. They represent a new type of interpreter that dramatically closes the gap between intent and execution, is self-corrective, and yields nondeterministic outputs that create massive amounts of "noise" 3. Their ability to generate and execute new tools on the fly, combined with expanded access, challenges the very foundation of a signature-based model of detection As these systems become increasingly intertwined with how we use computers, we must consider what it means to detect their misuse through out-of-context interactions with the host.

Today I am happy to release a new blog post about Pointer Authentication (PAC) on Windows ARM64! This post takes a look at the Windows implementation of PAC in both user-mode and kernel-mode. I must say, I have REALLY been enjoying Windows on ARM!! preludesecurity.com/blog/win…

This method demonstrates how hardware-level telemetry, coupled with contextual reasoning, can surface malicious activity that signature-based approaches will always miss as malware authors innovate in response. 📃Full write-up → preludesecurity.com/blog/une…

Today we're announcing an additional investment into Prelude from Brightmind Partners, @sequoia, @insightpartners , and others. preludesecurity.com/blog/ann…

Today I am releasing a new blog post on VSM "secure calls" the SkBridge project to manually issue them!! This blog talks about how VTL 0 requests the services of VTL 1 and outlines common secure call patterns!!! Blog: connormcgarr.github.io/secur… SkBridge: github.com/connormcgarr/SkBr…

Today we're announcing Runtime Memory Protection in research preview. This is a user mode _only_ agent designed to catch in-memory attacks, no matter how much creativity or AI the adversary applies. We believe it's the future of endpoint security.
