I don’t the author understands what the purpose of a prompt injection is. Computer Use runs inside your computer and not Claude servers. You are gaining access to your very own docker container.
For all of the excitement about "autonomous AI agents" that go ahead and operate independently through multiple steps to perform tasks on behalf of users, I've seen very little convincing discussion about what to do about this problem. Fundamentally, LLMs are gullible. They follow instructions that make it into their token context, with little regard for the source of those instructions. This dramatically limits thei…
So, if I may say, the question you allude to is wrong. The question IRT to SQL injection, for example, was never "how do we make strings safe?" but rather: "how do we limit the imposition of strings?".

The fundamental flaw people make is assuming that LLMs (i.e. a single inference) are a lone solution when in-fact they're just part of a larger solution. If you pool together agents in a way where deterministic code meets and and verifies fuzzy LLM output, you get pretty robust autonomous action IMHO. The key is doing it in a defensible manner, assuming the worst possible exploit at every angle. Red-team thinking, co…

Right, you have to keep a human in the loop - which is fine by me and the way I use LLM tools, but not so great for the people out there salivating over the idea of "autonomous agents" that go ahead and book trips / manage your calendar / etc without any human constantly having to verify what they're trying to do.
Tooling = functions. So no human in the loop. Of course someone has to write these functions, but at the end of the day you end up with autonomous agents that are reliable.

How do you stop agents from prompt injecting each other?
I was temporarily very interested in trying out Anthropic's "computer use" when they announced it a few days ago, but after thinking about it a bit and especially after reading this article, my interest has vanished. There's no way I'm going to run that on a computer that contains any of my personal information. That said, I played some with the new version of Claude 3.5 last night, and it did feel smarter. I asked i…
Just curious, before reading this, would you have given an alien intelligence access to your computer, not understanding how it works, and not trusting it? It doesn't have to be an AI, just ... an alien intelligence. Something not human. Actually, strike that, reverse it! Would you give human intelligence access to your unsandboxed computer? I wouldn't!

Don’t know what OP might suggest but my first take is: never allow unstructured output from one LLM (or random human) of N privilege as input to another of >N privilege. Eg, use typed tool/function calling abstractions or similar to mediate all interactions to levers of higher privilege.

My rule-of-thumb is to imagine all LLMs are client-side programs running on the computer of a maybe-attacker, like Javascript in the browser. It's a fairly familiar situation which summarizes the threat-model pretty well:
1. It can't be trusted to keep any secrets that were in its training data.
2. It can't be trusted to keep the prompt-code secret.
3. With effort, a user can cause it to return whatever result they want.
4. If you shift it to another computer, it might be "poisoned" by anything left behind by an earlier user.

Turns out LLMs don't work like that: there is no reliable mechanism to separate instructions from the data that the LLM has been instructed to act on. Everything ends up in one token stream.

A nice safe array of ints maybe?
