It really feels like there hasn't been any dutiful consideration of LLM and AI integrations into services.

Add to that companies are shoving these AI features onto customers who did not request them, AWS comes to mind, I feel there is most certainly a tsunami of exploits and leaks on its way.

Are companies really just YOLOing and plugging LLMs into everything knowing prompt injection is possible? This is insanity. We're supposedly on the cusp of a "revolution" and almost 2 years on from GPT-3 we still can't get LLMs to distinguish trusted and untrusted input...?

> Are companies really just YOLOing and plugging LLMs into everything knowing prompt injection is possible? This is the first time I’ve seen an AI use public data in a prompt. Most AI products only augment prompts with internal data. Secondly, most AI products render the results as text, not HTML with links.

It’s very common for AI products to render markdown with links and sometimes images, hence this problem: https://simonwillison.net/tags/markdown-exfiltration/

The real question here is who puts their API keys on a slack server ?

The API key thing is a bit of a distraction: it’s used in this article as a hypothetical demonstration of one kind of secret that could be extracted in this way, but it’s only meant to be illustrative of the wider class of attack.

I don't understand this. So the hacker has to be part of the org in the first place to be able to do anything like that right ?? What is the probability of anything like what is described there to happen and have any significant impact ? I get that LLMs are not reliable (https://www.lycee.ai/blog/ai-reliability-challenge) and using them come with challenges, but this attack seems not that important to me. What am I missing here ?

They have to be part of the same Slack workspace, but not necessarily the same organization.

The hacker doesn’t have to be able to post chat messages at all now that Slack AI includes uploaded documents in the search feature: they just need to trick someone in that org into uploading a document that includes malicious instructions in hidden text.

yeah so the same company. and given the type of attack have to have a lot of knowledge about usernames and what they may have potentially shared in some random private slack channel. I can understand why slack is not alarmed with this. would like to see their official response though

but the article does not demonstrate that that would work in practice...

Earlier quoted context omitted.

Can’t upvote you enough on this point. It’s like everyone lost their collective mind and forgot the lessons of the past twenty years.

This presents an incredible opportunity. The problems are known. The solutions somewhat. Now make a business selling the solution.

This is the fantasy of brownfield redevelopment. The reality is that remediation is always expensive even when it doesn’t depend on novel innovations.

The article says this: “Although we did not test for this functionality explicitly as the testing was conducted prior to August 14th, we believe this attack scenario is highly likely given the functionality observed prior to August 14th.”
