> "At the time of publication, no robust mitigation for the broader vulnerability class is available" Isn't it obvious by now that it's never going to be possible to fix this kind of thing, at least until we stop mixing up instructions with data.
That's what I always say, but nobody listens to me :D
Assembler had the same kind of design flaw, and we didn't learn anything from it as evident by LLM bypasses.

Separation of instructions and data is artificial. Reality has no such separation. A general purpose system needs not to have them either; it's a design feature, not a bug. People get too hung up on this fundamentally wrong idea, and the space of security, instead of progressing, is just running in circles like a headless chicken, making a mess of everything.
If you hand me two sheets of paper, one of them containing instructions and another containing data, I'll have a pretty easy time keeping them separate, and I think most humans wouldn't struggle with that problem either.
You think. But there are ways around that. How about a credible extortion message targeting specifically you, that is embedded somewhere on the data sheet? Suddenly, the data has become the instructions...

> A pure Harvard architecture machine has exactly that separation. It emulates and enforces that separation. A mathematical abstraction of a Harvard architecture machine has that separation, the real machine merely emulates it, and is only able to do so within some specific constraints (such as: no one hooks up dedicated programmer to the chip, or no one undervolts or overheats the cheap in clever way, or no one take…
Some hardware had segmented and tagged RAM as if it were a filesystem.

Mixing instructions and data is never a good idea. And I thought people understood that.
When working on PDFKit for MacOS, one short-coming our implementation had was the lack of support for Javascript in PDF's. Oops. (I mean, I'm one engineer and I was not going to try and hoist a JS runtime in my little PDFKit framework. And besides, the sample PDF's we were running into with JS were rare—usually tax-like forms that would add numbers from A and B and display the result in C. It seemed like a huge effor…

To drive the point about this being fundamentally unsolvable home, imagine a variant of this scenario. I could write an email that is directed towards that person, that says WE ARE STUCK IN THE SERVER ROOM AND THERE IS FIRE STARTING. PLEASE CALL 911 AND ALERT YOUR BOSS. Would you want the human assistant to just dismiss this as a prompt injection attempt? Or ignore it because they were told to treat e-mails as data a…
Why are the only options dismiss or ignore? Another option is to raise the message to your boss asking what to do.

Literally all of software is artificial? Being explicit and reasoned about how you choose to allow or deny a particular computation is, surely, at the heart of a lot of computer security?
Code/data separation is at the heart of computer security in the same way slapstick comedy is at the heart of humor. There's an endless supply of people who think they know what is Code and what is Data, and they're always arguing with others who also think that, and neither realize that Code/Data classification is an opinion , a perspective . It doesn't hold in general. Having a separation like this makes sense for…
Okay. To pull this back on topic, and to simplify it a bit so you can better grasp the core issue that's being talked about:
The "Unless your program requires it, always ensure that your code cannot be altered by the data it processes. And if you think that your program requires it, go back and think again." security lesson that the industry collectively learned like thirty or fifty years ago can be restated as
> Don't blindly do what some arbitrary stranger yelling in the street tells you to do.
Despite how passionately the major LLM providers claim they're super serious about security and alignment [0], we see time and time again that their tooling doesn't reliably distinguish between system instructions, -at times- its own internal chatter, user instructions, and attacker-controlled instructions. Companies that claim their tools are "aligned", but think it's okay for their tools to blindly do what some arbitrary stranger is yelling at them to do are not companies that are even a little bit serious about either security or safety.
[0] "Alignment" being a fancy word for "The software does what you told it to, and -once the software is much more powerful than it is today- what you actually intended for it to do.". Tools that mix together system instructions, user instructions, and attacker-controlled instructions and fail to reliably distinguish between the sources of those instructions cannot be "aligned". It's simply impossible.
I'm a programmer and a web-based AI user, but I don't want AI running on my local machine in any form. I've uninstalled Copilot and disabled AI in all local applications including the browser itself for exactly the reason described in this article. There's no way to protect your data from such an AI confusion attack by design. AI cannot discern your prompts versus text in file. The fact that an AI enabled word proces…
Agreed, I've done the same. Unfortunately Linux sometimes isn't a solution if the vendors we trust cross a line. Like recently when Google Chrome started adding its own local 4GB AI installation which caused an uproar.
Don’t use Chrome. Chromium, maybe.
the real upgrade from macro viruses is that the worm can now improvise. last time it needed a script, now it just needs a persuasive paragraph.
