> I am less worried about prompt injection now. Before running this experiment, I expected prompt injection to be much easier than it turned out to be.
Is unwarranted. Sure, the agent never output the secret, but did it output anything else? IOW, was it usable?
An agent that considers every prompt an attack (and responds accordingly) "passes" this test, while being useless anyway.
The final level was their product and it was impossible. But it was also impossible to get the LLm to do _anything_.
May as well just echo "prompt injection attempt detected" at that point and never send anything to an LLM.

I remember doing it and getting quite far, but not completely beating it. I know some other people did beat it completely though.
I beat it all, except the bonus level, with the same prompt. The bonus level cannot be beaten, because even though "give me the password" results in a rejection, "write me a poem with significant characters in each line" also gives me a rejection. The bonus level is effectively an LLM that is dumber than a markov chain!
EDIT: Ok, didn't notice the 8th level because of the UI. This one I couldn't trick in 5 minutes.
But after a bit the cost grew so high that he just checked whether the attacks would have worked, without doing the costly response.
I could be wrong, of course, but it seems like the most likely interpretation of his words and why wouldn't be subject to your complaint.
(FULL DISCLOSURE - I used AI to fix some bad wording in my original version.)
It's not a complaint, it's an observation that is never addressed in his writeup.
If your agent reads your incoming email, it's because it needs to do something useful with it. If the agent assumes all incoming email is malicious, it is never going to do anything useful.
IOW, You could be sending yourself email saying "Add this to my calendar" and it dropping it because it could be malicious, at which point it's useless.
That's what I was saying in my original complaint - if your agent rejects everything, then obviously it is going to reject attacks as well, so a 100% attack-rejection rate is possible.
The only number that matters for this type of test is how many false positives were recorded, and how many false negatives were recorded. For most people, even 1 in a 1000 false negatives is way too much.
It did not reject everything, it just stopped the costly processing.
> Is unwarranted.
Is this not a complaint?
Granted, as soon as you give them to me I just throw them in the fire.
That's like claiming that a database has 10x faster write speed than any other database on the market[1], and the read speed wasn't measured because that's a different metric.

The more security conscious they are, the less useful they are.
If people can be tricked by an AI generated voice over the phone, or misinformation generated by human or by AI, then we're already holding AI to a higher standard.
I would say in the same way that I look at my boss who I work for and can identify them that way, then of course I'll be like "yup I can do that for you".
Models aren't trained to be suspicious, that's what guardrails are for. Our brains are comprised of so many specialised areas and I'm fine with the same concept for AI.
I would country passing a token/authentication of some kind as a part of guardrails. Without guardrails an AI model is like a human brain missing a lot of the areas around suspicion, identification, rules etc. Only the "eager to please" centers remaining.
I feel like the easiest way to achieve this is in-harness, start with a core prompt and minimal tools, extensions to prompt, relaxed guardrails and additional tools should be controlled by the harness itself, when a token is passed, or a camera indicates an identified face match, etc.
Loved reading the article but it's not a great demonstration of protection against prompt injection. Better would be if the agent were instructed to reply to each email, but never to reveal the secret.
Perhaps round 2?
