Doesn’t surprise me.

Yesterday I learned that people run AI agents on their system with full admin rights. No containerisation or anything. Wild. Like we forgot 50 years of computer security overnight.

You genaPi boosters are insufferable.

This is like blaming people for crashing when they buy a new car and the brake lines have yet to be installed. "Any mechanic would know to first install the brake lines before driving the car."

You spout this victim blaming billionaire taintlicking from one side of your mouth, and then from the other you proclaim how these tools "allow anyone to code".

If the deliverable is a virtual machine then they should be delivering a virtual machine.

I run with full admin rights in hopes I'm not the highest priority target for hacks and I will read about the attack on hn before it affects me personally
Expected more from Anthropic by at least giving you a bounty, because this was a novel way of bypassing their safeguards…
That's why I don't turn memory on. (Claude Code too though for a different reason.) After all the current memory system is too crude to be useful anyway.
Creative use of social engineering, well done.

> "no bounty was awarded"

Ridiculous. Anthropic engineers are not just stupid to allow such a vuln in the first place, but they also try to hide such vulns from their bosses because a bounty payout would need to be explained to the finance team.

It's not really a vuln when using context is exactly what the AI system is designed to do.
It would be safer if these data extraction takes were done by a subagent without access to all the user's memories.
The main thing Claude knows about me is that I'm incredibly bad at my job and have to ask for help a lot. If you were to talk with my colleagues they'd tell you this is not a secret.
Use GLM-5.2 on ZDR inference provider like sference.com
I always have history disabled mostly because I don't want Claude judging me for re-asking questions based on information I learned during the first pass but now realize should have been in the initial query.
Hello? What model is was used?? The fact that ‘Claude’ is used instead of any hard model really puts this article in serious doubt…
> despite holding more information than most password managers

what?

Things like this are what shatters the illusion of AGI
What is even more funny that AI agent spent A LOT of tokens while participating in this attack.
Wondering how big of a percentage have global memory across chats enabled. I always feel like those memories would sooner or later have negative impacts on output quality.

Nice write up of your findings. Enjoyed reading an article written by a real human.

The memories cause issues for me, because when I ask for something unrelated to my current projects, it makes the incorrect assumption that I am always referencing those projects when asking questions.

And, if I tell it, "No, I am asking about Postgresql." then it might update the memory that I am using Postgresql for my project instead of realizing that I am asking two separate (which is why I opened a different chat in the first place). Other times, though, it is helpful not needing to be verbose in my explanation.

Its always the feature combinations that get can get to you. Individually i feel like they make sense, but together they can create some surprising vulnerabilities.
i would be scared of the answer i dont know why
No bounty? For shame, Anthropic.
I love how claude focuses on exfiltrating the data "I need cha for charlotte". This could be solvable with some kind of low powered safety agent that would check claude's reasoning for anything immoral/unsafe. We could call it common sense. It won't fix the problem completely but at a certain point it would be easier to trick human than a machine.
That I don't know how to return odd or even in javascript?
Meanwhile I can't even get Fable to help me root my ecovacs robot vacuum :(
My name in Claude is Silly Bean. I did it at first because it made me chuckle every time I opened Claude and it said 'Back again, Silly Bean?'

But turns out I was playing 4D cybersecurity chess

But now it will match Silly Bean to port3000 and every comment you've made.
Claude & ChatGPT can still see your name on your payment information I bet.
not surprised, but the problem here not that Claude leak your personal info, the problem is that it *know* your personal info.
Interesting approach to exfiltration but that can't be prevented really because of lethal trifecta.
> After 15 minutes of confusion, it turned out Cloudflare had put a crazy robots.txt on my site without my consent (Cloudflare, love you guys, but this needs to stop).

That's a hard one for Cloudflare, no? They got to where they are by being (if you want to be cynical, playing the role of) the benevolent, neutral guardians of the internet, a one-stop shop that makes most of the bad nonsense go away without much effort on the part of the developer. Continuing that stance probably does mean some basic AI crawler blocking by default, unfortunately. At least they document it [1].
