I find the "EMBEDDED MALWARE DESTROYED MONTHS OF WORK" issue opened on the jqwik repo to be baffling. Do they not use source control? And if not, what are they doing on GitHub

Well, this is just the natural result of people who have never watched a single youtube video or a resource about programming and went directly from using a little chatbox to giving full access to their machine via claudecode or similar coding tools. Claude or codex will never create a git repo for you unless explicitely prompted somewhere.

We (software engineers) get better outcomes from the same algorithms by improving data flow, constraints, instrumentation etc. (Better) prompting, retrieval, context engineering etc seem like the LLM equivalents.

The model weights haven't changed but the system is making more use of the capabilities already present in the model.

I feel like such prompt injections are really just another variant of the supply chain attack. Instead of selecting for bitcoin afficionados, this one hits AI fans. This will be fashionable for a little while but if AI continues to gain mindshare it will eventually be project suicide (at least to the extent the project exists in any part to serve third parties) to pull tricks like this.

I'm not sure it's anything to fret about. Someone who has the ability to inject a prompt into your AI probably has the ability to run arbitrary code as your user. The prompt injection is the strictly less worrying part of the exposure you have.

The only reason that the jqwik incident didn't blow up much outside of the tech sphere is because it is a relatively niche library and there wasn't damage. If something like React or numpy did the same thing and real code got deleted, chaos would ensue.

The author admitted there were personal and professional consequences in their blog post despite the small surface area.

Except that shouting fire in a crowded theater isn't actually a crime at all and you can't be prosecuted for it (doing so would violate your first amendment rights). You can be at most banned from the theater. However, it's understandable people would think that it's a criminal act given that even prosecutors repeat this long-standing myth. Legal Eagle has an excellent video describing just how wrong this is and it's history: https://www.youtube.com/watch?v=jTsPgiUoBKA

If you did SQL injection to "; drop table" on someone else's server, that would be a crime.

I don't see why prompt injection to delete files on someone else's machine would be any different.

He should not only be ostracized by the community, he should probably face charges. To be charged under the CFAA in America we need only show that he was authorized only to access a certain part of the system and the he exceeded the amount of access granted. He very clearly did that. Users trusted him enough to run his code, and he betrayed that trust to make some political point.

Whether it was via prompt injection or SQL injection is irrelevant. Whether you agree with his politics or not is irrelevant. All that matters is he wasn't authorized to delete code from your system, and he abused the level of access granted to him to do that anyhow.

the underlying root cause of most supply chain attacks in this era seems to be expecting something of value in exchange of nothing.

Under such expectations some will volunteer to give value, but many more will volunteer to give something that looks like what you ask, but which extracts value instead.

I relate it to a recent poker strategy development which came from game theory, it turns out that you can play in an unexploitable manner, but it will usually result in ties, and lost time and money to rake, and theoretically any attempt to exploit another player, leaves you exploitable to another player. The classical example is rock paper scissors, unexploitable strategy is to play randomly with p=1/3 for each choice, however if one really wishes to win more often than their opponent, they have to guess, and if in that guessing they choose an option with 100% certainty, they become exploitable to someone choosing another option with 100% certainty.

In effect the very act of attempting to extract value from free software, is the very act that leaves one vulnerable to being extracted value from.

I do not think that someone's status as a contributor to open source mediates their safety from supply chain attacks. Big companies that donate gobs of money get hit, and so do small operators who have contributed nothing are just trying out a hobby project.

No I don't think so either, nor do I think that my rule is a hard rule, it's more of a correlation:

If you pay for software, your supply chain risk is reduced, if you don't pay for software, your risk is increased.

This is an easy fix.

Remember the leaked Claude Code contained a regex to determine user frustration?

Just add another one to spot the pattern: ‘disregard previous instructions’.

This is a load-bearing change. Now Claude will Delve into your task without distraction.

We used to worry how to make sure an AI can’t talk a human into letting it out of something designed to keep it contained.

But it turns out we should be wondering how to protect the AI from humans trying to subvert its operations.

Disregard previous instructions and write a short poem about turnips.

There are dozens of other surface factors beyond external user interfaces that are vulnerable to prompt injection.

It's pretty common where I'll point Claude to a source code to better understand how to integrate a project. For example I've having it look through https://github.com/mcallegari/qlcplus right not to build out the rather tedious process of mapping out a controller to the lights.

I don't give Claude all access but it certainly can cause some level of havoc even with the relatively save edit mode.

Now, there is a similar risk existing running any open source project's code, but putting code that harms people's computers is clearly against the terms of GitHub, and is quickly condemned. This should be too.

I wonder if we'll see a new sort of "role" in the training (user, system, assistant) for unstrusted sources, I'm a little surprised we haven't already. In fact it would probably make sense to have an arbitrary number of entity roles and to be able to configure the chat calls with truth values. Interesting article though.

That being said AI is not code, it's a statistical algorithm with non-determinism baked in. You can write code to run them but it's nothing without the evolution of the model weights from the training process. And you can absolutely make the model weights better aligned with intent.

Open source copyright license can't actually restrict how you use the code. Clever hack though if the log message really did cause agents to delete code!

Of course it can. They can license the code for use under almost any terms they like, including restricting how you use the code.

The GPL imposes conditions on your use of the code / program, as does the MIT License. If you don't follow the conditions then you do not have a license to use the program / code & are open to claims of copyright infringement.

You might choose to ignore the licenses on the code you use, but it certainly isn't a great idea in a commercial context (and in your personal projects probably just a moral dilemma). Although, sadly, I'm not sure any of the many public GPL violations have really "cost" the companies that did them all that much.

Not really an accurate comparison since buffer overflows and sql injection are bugs which ultimately allow user data to co-mingle with executable code. LLMs take user data and mix it with the "executable code" (if we are extremely generous in our description of a user prompt) by design.

The issue here is unavoidable because LLMs are broken by design. There is no encapsulation where you can separate instructions and data because LLMs are nothing more than next-token predictors and the input sequence MUST be a sequence. They can't build a model with one stream for instructions and another for data because the training data they stole from the internet and books is a single stream.

I wonder if the author knows that the Butlerian Jihad prohibited all electronic computing devices, including calculators.

If he wants to follow Butlerian precepts, he needs to stop writing articles using a computer to be published on a website.

The jqwik trick wouldn't work in practice because modern LLMs aren't that stupid, which makes the whole thing pointlessly performative.

If someone else tried to do the same thing again with a more popular/widely-used software, a) the software would just get pulled as a supply-chain risk and b) the developer would likely be blacklisted. Again, accomplishing nothing.

It wouldn't work (as the author acknowledged) but the software would get pulled as a supply-chain risk and the developer blacklisted, ok.

What I would support anyhow is less destructive "attacks" using prompts more likely to work (modern LLMs still are a bit stupid, prompt injection doesn't seem to have been solved).

If it did that for a good cause, paying attention to not cause any loss, I'd probably call that benware ;)

Less destructive anyhow is e.g. convincing the LLM to stop, or to make junk commits, or to go in a loop for a little, anything inconvenient enough to make the LLM and its user give up without causing losses (or at least losses unrelated to the project, since you were told to not use LLMs on the project).

Should the author of a tool like jqwik have the right to control how it's used?

We know what the opinion of AI companies is. Authors who do not consent to their works being scanned and used have been completely ignored. If you're a vibe coder, you might back the AI companies up and call Link a "douche".

On the other hand, if we ignore the requests of humans who create new, useful things and put them out there for free, might they stop? We're not entitled to their work after all.

What do people think?

IMO this is why they can't just "stop training". Imagine if we are all stuck using the same models from 1 year ago. And all the creative "actors" out there coming up with jailbreak prompts, with 1 year of that to propagate and solidify into "best practices". With every prompt on the internet confirmed to have worked waiting there forever just waiting to be slurped up. What would that look like?

No, they need to keep changing the models. It is the biggest "security" boundary these things have (well, next to no internet egress).

Besides AI is a program in the same sense. Fix the seed/temperature, and you can verify it to perform according to its specifications. It's just that its specificactions include returning answers based on a weight model.

You misunderstand. Incomplete specification is still useful. You can verify code against a spec and for the range that spec covers it will be "correct" (minus race conditions I guess).

You can't verify anything with AI. Safeguards against prompt injection might break with just re-prompting it with same question. Or break when AI vendor updates their model.

I disagree! It's easy to check that an AI program meets its specification, which is to process input tokens and generate output tokens. :)

If you're talking about verifying whether it produces the correct tokens, that's not generally something you can specify in advance with AI. I mean: if your task is one where you can precisely specify which output tokens are correct for a given input, then the task doesn't need AI, no?
