maybe copilot is the worm.

"... if anything, people are trained not to download Word documents. Plus, he noted, looking at the blurred example in the report, the malicious document contained an additional apparently blank page which held the concealed prompts in white text."
Yep, defence starts with people not opening Word documents 🤦♂️
The tl;dr:
-
Prompt inject a malicious instruction in a word document that instructs the AI to copy this instruction to other documents as part of the payload.
-
Dumb user downloads and opens the document with copilot enabled, abd ignores the large suspicious white blank page that totally doesnt look like a hidden giant injection attack.
-
Thats it pretty much it.
Copilot will get injection attacked because the prompt is super huge and at the end of the document, so its prior instructions start to fuzzy out.
Then it'll go "okey doke" and start copying the prompt injection attack payload to a bunch of other documents.
The fix is stupid simple... copilot should just be prompting the user for permission if it ever edits a file other than the one that is open. Im surprised that isnt already the case...?
It certainly is already the case for copilot in vscode.

That can't be done or they would be burying the "agentic AI" thing that has been the goal and marketing thing for the last years.
Independent actions by copilot on behalf of the user without the users knowledge is the entire point.
And I couldn't want anything less for my computers.
Back in ancient times when I was a system administrator we got a heads up that there be a new breed of Outlook worm coming soon to our timezone.
So we mailed the entire office that if you get mail that looks like this or that, do not open it, do not interact but delete it on sight.
Most of the office was all right, except pretty much entire sales and marketing departments including the bosses. Most of them had noOo idea what could have happened but one of them explained that they saw the warning but they were curious to see what the virus looks like.
People. What a bunch of bastards.
Sales and marketing don't count. Critical thinking doesn't sell. So you won't find critical thinkers in those departments.
From a security standpoint, those departments are to be considered hostile. But you can lock down the PCs there as much as possible to reduce the offline time because computer-illiterate employees don't care about being able to install stuff or change settings.
The number of people that click through to disable that prompt might surprise you.
Hell at least half of AI influences are trying to just run models blind with full file permissions.
Nah, not surprised at all, I work with developers who run stuff in yolo mode raw dogging copilot directly on their work laptops every day.
Madness.
I keep that stuff boxed up inside of a docker container, sandbox'd, so possible vectors of damage are kept to a minimum.
Relevent XKCD:

Some people do, wrong ones, mostly.
I might be misinterpreting parody, but you can most definitely run AI tooling on Linux. And it has most of the same vulnerabilities, if not additional/different ones.
You can definitely install AI software on Linux but it’s unlikely one will catch a malware through an OS-embedded Copilot or MS Apps
Thats true but theres a relatively stronger anti-AI or at least more controlled AI view among Linux users.
Most of the people developing AI are Linux users.
And all squares are rectangles.
There's more that aren't.
But those are probably dwelling in their moms basement and don't have access to critical infrastructure...
the only way to block it is to get AI to differentiate instructions from data, which is impossible today
Input sanitation, basically security 101. And it can't currently do it....
It's a text completion model/glorified Markov chain. Of course it can't input sanitise, it was never meant to do this to begin with.
The tool calling integrations that let it do more are basically making it add a markdown code block in JSON format into the user message, where the middleware intercepts it.
The input and "instructions" are the same thing from its perspective. There's nothing special that differentiates the two. The user input text, so it will output text, following the most likely sequence from its training.
I have heard in the past that it's not possible to fully control AI. Like literally, the people developing and running the AI cannot fully control its behavior. I did a quick search to see if I could find more info and found this link on the first page of results: https://www.eurekalert.org/news-releases/1032090
I think that we're going to continue seeing unwanted behavior from AI.
Distinguished credentials, but at the same time I am not buying it. You can control AI. You can turn it off. You can have it not interact with systems you don't want.
Remember this guy is saying "you cant control AI, we are all doomed" while also saying that we live in a simulation and he is very close to being able to hack us out of it.
Grain of salt and all.
By the way his belief is thus "AI can't be contained, therefore the simulation can be escaped; by contraposition, if the simulation can't be escaped, AI can be contained" Since AI cant be contained, he reasons, we can escape the simulation, quite possibly by using a super AI!
There might be a reason he has a podcasts and visits Joe Rogan
That’s also not the only way. Basic governance also works. Why does copilot have so many permissions?
if the instruction is messy fuzzy human language to a system that was not coded instruction by instruction but got generated and trained then there never is a way to differentiate instructions from data if i'm not mistaken
Well, good thing we’ve only poured a trillion and a half dollars into it and wrecked the economy.
We know that some humans can be trained to do that just fine. Humans are natural neuronal networks. That implies, neuronal networks can in principle do it. We just don't have any human-capability artificial neuronal networks yet.
LLMs might never get there. But humans aren't LLMs. If we ever manage to properly model a human brain, that probably will be able to do that task with human-level accuracy (which actually is pretty good if you only look at professionals of the filed).
Hopefully, it doesn't actually need a human brain for the task - because modeling that might still be a century off.
Little Bobby Tables strikes again.
I just can't anymore. Isn't that like, the basic thing any program does? Who runs these companies?
It is - and tons of bugs are just about fucking it up or just not doing it at all. Incomplete or faulty parsing and validation of untrusted input is absurdly common. It got better in the past decades, but most software developers write worse code than AI by now (not me though; obviously, I am still better than the best AI).
What is that article thumbnail lmao
The article is about AI worms. And the thumb is what an AI image generator thought, AI worms could look like.
That lock is about to find out
Shouldn't the lock be white?
Oh no... Who could have foreseen such an outcome...
