What we need is zero trust at the interaction level. Let an AI perform tasks without ever seeing the sensitive data it is using.

Even recording (which they already are doing) is not exposing sensitive content.

Mix that with hardware enclaves and you actually have a solution to these security and privacy problems.

This isn't an AI problem, its an operating systems problem. AI is just so much less trustworthy than software written and read by humans, that it is exposing the problem for all to see. Process isolation hasn't been taken seriously because UNIX didn't do a good job, and Microsoft didn't either. Well designed security models don't sell computers/operating systems, apparently.

It's pretty clear that the security models designed into operating systems never considered networked systems. Given that most operating systems were designed and deployed before the internet, this should not be a surprise. Although one might consider it surprising that OS developers have not updated security models for this new reality, I would argue that no one wants to throw away their models due to 1) backward co…

Having flashbacks to Windows 95/98 which was the reverse: The "login" was solely for networked credentials, and some people misunderstood it as separating local users.

This was especially problematic for any school computer lab of the 90s, where it was trivial to either find data from the previous user or leave malware for the next one.

Later on, software was used to try to force a full wipe to a known-good state in-between users.

It’s also an AI problem, because in the end we want what is called “computer use” from AI, and functionality like Recall. That’s an important part of what the CCC talk was about. The proposed solution to that is more granular, UAC-like permissions. IMO that’s not universally practical, similar to current UAC. How we can make AIs our personal assistants across our digital life — the AI effectively becoming an operatin…

I think what parent-poster means is humans dream of something at least like, say, ship's computer from Star Trek, which accepts some degree of fuzzy input for known categories of tasks and asks clarifying questions when needed.

Albeit with fewer features involving auto-destruct sequences... Or rogue holodeck characters.

In exasperation, people truly concerned about security / secops are turning to unikernels and shell-free OS; at the same time agents are all in on curl | bash and other cheap hacks.

> Well designed security models don't sell computers/operating systems, apparently. Well more like it's hard to design software that is both secure-by-default and non-onerous to the end users (including devs). Every time I've tried to deploy non-trivial software systems to highly secure setups it's been a tedious nightmare. Nothing can talk to each other by default. Sometimes the filesystem is immutable and executabl…

I don't know exactly which "secure setups" you are talking about, but the false equivalency between security and complexity is mostly from security theater. If you start with insecure systems and then do extra things to make them secure, then that additional complexity interacts with the thing you are trying to do. That's how we got into the mess with SE Linux, and intercepting syscalls, and firewalls, and all these other additional things that add complexity in order to claw back as much security as possible. It doesn't have to be that way and it's just an issue of knowing how.

If you start with security (meaning isolation) then passing resource capabilities in and out of the isolation boundary is no more complex than configuring the application to use the resources in the first place.

A large percentage of my work is peripheral to info security (ISO 27001, CMMC, SOC 2), and I've been building internet companies and software since the 90's (so I have a technical background as well), which makes me think that I'm qualified to have an opinion here. And I completely agree that LLMs (the way they have been rolled out for most companies, and how I've witnessed them being used) are an incredibly underest…

Signal has been trying to tell us for years now that their service is already compromised. That's why they've refused to update their privacy policy after they started keeping sensitive data in the cloud and even after they started keeping message content for some users.

coming from the fact that this was a talk held at #39c3, maybe, just maybe, this was not about selling anything at all?! i feel like that might be hard to grasp for some HN users.

Since Signal lives and dies on having trust of its users, maybe that's all she is after? Saying the quiet thing out loud because she can, and feels like she should, as someone with big audience. She doesn't have to do the whole "AI for everything and kitchen sink!" cargo-culting to keep stock prices up or any of that nonsense.

How can a service like Signal live and die by the trust of its users when they openly lie to them. Signal refuses to update their privacy policy to warn users that they store sensitive information in the cloud (and more recently, even the contents of user's messages in some cases).

Lying to users by saying that signal doesn't collect or store anything when they actually do doesn't sound like something a company who expected you to trust them would do. It sounds like something a company might do if they needed a way to warn people away from using a service isn't safe to use while under a gag order.

I remember playing around with what sounds like Recall's predecessor back in 2009 [1].

It was only a Microsoft Research project at the time…

Not to take away from the very real security concerns, but this quote is blatantly false to anyone who has used Claude Code or Cursor:

> She said if an AI agent could perform each step with 95% accuracy–which currently isn’t possible–a 10-step task would yield an action with a ~59.9% success rate. And if you had a 30-step task, the success rate would be ~21.4%. Furthermore, if we used a more realistic accuracy rate of 90%, then a 30-step task would drop down to a success rate of 4.2%. She added that the best agent models failed 70% of the time.

Yeah, her estimates seem a bit too high based on my experience
