"if the agent ingests anything, then it's permissions should be dropped to the level of the author of that information" I like that lot, it's a very succinct way of explaining the problem here Anyone who can author text that gets into your agent can control what that agent does…

We’re thrilled and honored to reveal our second keynote speaker: Ivan Krstić (@radian) Any guesses what he might talk about? 😉
Dutch Waterfall scans coming out of the Netherlands, how you can tell over 1,400 IPs are working together, and novel temporal fingerprinting/visualization for scan traffic! My PhD research. lightscope.isi.edu
Memory safety++. Many engineers have contributed to the deep- and wide-reaching implementation of this! Software flaws will continue to exist but exploiting them grows harder and less economical. Read the blog, and take advantage in your own applications via Enhanced Security.

🔺iPhone models announced today include Memory Integrity Enforcement, the culmination of an unprecedented design and engineering effort that we believe represents the most significant upgrade to memory safety in the history of consumer operating systems. security.apple.com/blog/memory-in…

Great job: the Government’s Sovereign AI unit is looking for someone to come and lead a team focused on special projects for UK sovereign advantage Ideal for someone early ish career looking to do a tour of duty to help ensure the UK is an AI maker, not an AI taker
Today @wesstreeting has shared publicly his concerns about yesterday's AD vote. I agree with every word. Each £ of money used to fund dying will be a £ removed from NHS & palliative care - which is already in desperately short supply for terminally ill patients. This is the care…
Please, MPs, before you vote on tomorrow’s AD bill, I beg you to ask yourselves why the @rcpsych felt compelled to publicly oppose it…. Ask yourselves why the vast majority of palliative care doctors, geriatricians & groups representing people with disabilities, eating…

MPs voting on Friday need to watch this. This gets to the heart of the first vote on NC16 - this Bill doesn't care why someone wants to end their life - and the complete exclusion of family from the process (MPs have signed that off already) credit: @nowaybackorguk
The assisted dying bill is deeply flawed, unsafe, a source of danger to our most vulnerable people and of deep concern to our leading healthcare professionals. MPs must heed this joint statement of the Royal College of Physicians and the Royal College of Psychiatrists…

The story behind the Apple Password Monitoring service, handling multiple billions of requests per day from devices all over the world, which was recently rewritten in Swift: swift.org/blog/swift-at-…
@windsheep_ I see it as a signal that cybersecurity doesn't have enough engineering in its DNA yet, so we lean in on applying our expertise as analysts rather than scaling by applying engineering. It's like classic ops vs. SRE.
Kim Leadbeater claims today her bill has been “thoroughly strengthened” in Committee. Views may differ. Here’s what the Committee thinks MPs should sign off
Fascinating first day in the Terminally Ill Adults (End of Life) Bill committee, hearing evidence from experts (most of them pro assisted dying). Main takeaway: it really isn't clear what shape this Bill will be in when it comes back to the Commons. Issues that arose:
I am moving to London Kernel engineering team next month. And we are hiring. Please apply if you are into Kernels/OS/Security. At the core of our OS, you'll be able to influence the design and implementation of the OS that runs billions of devices. jobs.apple.com/en-us/details/…
