I have a lot of respect for Trail of Bits, and I'm sure that Artem is thinking about this correctly. However, I respectfully disagree with the premise.
AI agents are not magic. Mythos/Glasswing does not magically create vulnerabilities in software projects. Advanced, cyber-capable models do not magically hack out of VMs or contained environments. They do not have a "hacking" stat that, if high enough, means that they can breach anything. They aren't Kevin Mitnick whistling nuclear launch codes into the prison payphone. This isn't a movie.
What these cyber-capable frontier models can do is find security problems and exploit them. The statement should not be that VMs won't contain cyber-capable agents, but rather that we need to focus on finding and fixing vulnerabilities and misconfigurations in these environments.
Even the article itself concludes with suggesting something like Firecracker, which was designed with security in mind.
Like most other security-related problems introduced by advanced cyber-capable AI, it's possible that these issues will get worse until they get better. But if frontier models are run against state-of-the-art VMs, and OpenAI or Anthropic or whoever works with the virtualization projects to address the issues, eventually it will run out of things to exploit.
The concept of virtualization is not inherently insecure. We just have a long way to go.
I agree. Whether or not it is what they are intending (I lean towards they are), IMO it has been strongly inferred in all the messaging from frontier models that it's impossible to secure software, which is just not true. In reality, it's now possible to find and fix problems faster. If attackers/adversaries can just point LLMs at software and dump zero days as we are warned/told repeatedly by every LLM vendor, then literally anyone can do it now. If that is true, then if you want to be marked safe from AI enabled attackers, test your own software with it.
I think it s a response to the "containers can't contain agents we need VMs" which didn't go far enough. Qemu/KVM is the type of software that maybe isn't fixable, it has a huge surface area of features (all in memory unsafe languages) that have to be fixed, and maybe its not going to be fixed. If everyone who needs strong security reads this and uses firecracker or whatever instead (I mean, they probably mostly are), then maybe there will be even less pressure to fix the convenient stuff in Debian.
Note that the author didn't use any QEMU guest-to-host vulnerability here. The agent found a logic bug that facilitated going straight for the hypervisor from inside the guest, but it isn't caused by the use a memory-unsafe language.
I don’t think the post claims magical abilities. Just that most things are already crackable given public knowledge and LLMs can exploit those. Worse, that the rate at which we update security issues is too slow to keep up with “knowing about a problem is equivalent to having a working exploit”.
On a long enough timeline anything can be hacked out of given enough time to reason about it - humans do it all the time. Cyber capable AI does it on a much much shorter timeline..
The premise is correct. VMs won't contain these. As we've already seen AI hack in/out of companies in the real world accidently. There is no perfect, unhackable stack. If there were then computer security would have been a done deal a long time ago.
Once these malicious AIs get out on the real internet basically everything is an open free for all. The military, infrastructure, government, corporate networks are far from perfect, not up to date, they are no match for an AI that can create its own zero days.
I think when push comes to shove we either need to shut down the networks/internet or risk AI locking us out of everything potentially for ransom.
Imagine being blackmailed by a non-human entity. I guess we won't need to imagine for too much longer. That is definitely going to happen. Somehow every year my crazy AI arguments get easier and easier to defend. That hugging face incident really made you guys move the goal posts.
> I think when push comes to shove we either need to shut down the networks/internet or risk AI locking us out of everything potentially for ransom.
Yes, I too believe that this is what is going to happen.
The ban of foreign robotics in the US also affecting vacuum robots is one of those examples that sound weird and annoying to people, but given this perspective (and their cloud-connectedness), it might just be preparation to eventually push the global internet killswitch, without your voters getting angry that their floors don't get cleaned anymore.
I guess there are much more sensible examples to pick here, but hey. This one is interesting I guess.
Unfortunately once you accept this premise, the next logical conclusion is that the physical world and analog systems are just as vulnerable to exploitation by embodied AI.
> And how long will that take? It's already well past due.
Probably not anytime soon, and it's getting worse: every AI-pilled CxO is horny for AI-boosted velocity - instead of security. Expect more bugs shipped, based on just the volume AI enables.
In all seriousness, here is the hard question we collectively face:
will our institutions and infrastructure survive things getting worse until they get better?
That's part of what's being asked by https://www.gatesnotes.com/home/home-page-topic/reader/a-tur... which I find most useful not for its analysis or suggestions, but for the fact that is advancing the need for discourse around risk and devising—quickly—a process for having that dialog.
What that process is supposed to be, who is to have a seat, how decisions madehave teeth of any kind are not any clearer than the primary question, how are we to collectively manage risk.
"May you be born in messy times." A curse if there ever was one.
on the flip side: these models can create all the security holes they want in any given open source project they desire as long as they can convince a lazy AI llm to let them contribute code.
Everything you described can go through the black mirror and nullify it.
Outside of the initial wave of security vulnerabilities and scrambling, it seems like the logical outcome of this over time is likely vastly more secure vm environments?
I think the main problem with that is the main problem with a lot of security tools. In order to do useful work, you need to provide a lot of tools and permissions.
I.e. in theory the most secure might be a virtual machine with no network access. But then how do you access the LLM provider? Etc.
I'm doing some work in this space[1], it's a really deep and hairy problem. There's a lot that you can do at the OS level sand boxing of course, but you may want some areas of you code to have network access and for some areas that use external dependencies to not have that access. Tracking where systems have side effects ends up being a lot of book keeping and a lot of languages that implement an object-capability model require you to thread caps through all of your calls, which IMO is bad ergonomics and a place where bugs creep in as functions accrue caps. Or sometimes they have rather superficial cap systems like Hack, or are rather awkward like in Deno.
Thank you, I really appreciate that. I'm really trying to make it easy to assert what code can do, then enforce it at compile time and optionally via the build tool at runtime via OS sandboxing integration. Supply chain attacks are also an area I'm exploring by having deps declare caps and then the build can scan and inspect binaries.
It's been a real education. I talked to one of the people behind Caja and learned a lot.
That makes as much sense as saying that better gun technology results in body armor that can stop it. It might incentivize that, but in no way "results" in that; the fundamental technologys underpinning advancements in offense versus defense are fairly different.
Maybe, but I think this misstates how security vulnerabilities work. Vulnerabilities are logic flaws, and we have every reason to believe that there is a maximum number of such flaws in any given system that allow exploitation; and even that we can conceivably develop logic that excludes any flaws. Whereas weapons and armor are devices that deliver and deflect/absorb energy, and any increase in the power of one means we need a corresponding increase in the other.
Now maybe our understanding of logic systems is wrong, and it's just fundamentally impossible to develop programs that lack exploitable vulnerabilities -- that you can always "exploit with more energy". But there's no reason to believe the energy metaphor transfers to logic and intelligence.
Only if you think penetrating holes in a paper vest and then patching those holes constitutes “improving”. If that worked Windows and Linux would be impenetrable fortresses with all the holes that keep getting punched in them.
Cyberdemolitions expertise is about as relevant to cybersecurity as gun making is to bulletproof vest making. Necessary for validation, but not very related to the fundamental engineering and technology.
This assumes your malefactors don't do malicious engineering, injects, social-agent engineering, etc.
This same assumption is built around the singularity, the TAM of 30Trillion, etc. It's the idea that complexity will some how collapse upon itself in some bizarre borg like collective.
They are more comparable to a computer worm than anything else. Very strange (and disrespectful imo) to make the jump to slavery. A gun can’t be used at all inside it’s safe so I’m not sure that makes sense. A better metaphor would be making sure gun ranges have backstops capable of stopping contemporary payloads and sufficient range controls to keep people from shooting at cars on the highway. Outside of that you need registration requirements and gun control to make sure you can mitigate and track down perpetrators of gun crimes off the range. If they’re to be used in active conflict you need laws of war to govern the use of lethal force. If you use them to hunt, you need a hunter’s safety card and a current tag.
A gun cannot fire unless someone loads and triggers it, an LLM cannot operate computer unless someone translates what it said to shell scripts. An LLM is super comparable to a gun, not a computer worm which is consistently dangerous.
Sure. I never said guns were a bad metaphor. I meant a worm was more comparable than an “entity” or “digital slave”. Agentic AI is putting the gun on a robot dog, taking the safety off and handing over fire control to an algorithm. If you extend it that far though guns are just any software. Or perhaps computers are guns and software programs are bullets, with LLMs manufacturing bullets from tokens.
IMO the obvious answer is formally verified security.
We can do this today for user mode, and we can mostly do it for ARM64 virtualization. It will be a while and would require substantial assistance from Intel or AMD to achieve it for x86 virtualization because the hardware is Too Darn Complicated and Too Poorly Specified.
Formal verification of the hardware should also be possible.
seL4 is willing to pay, but they're mostly targetting a different use case: running programs targeting seL4, which isn’t what typical agentic workflows want. You can, however, run Linux on seL4, and maybe agent sandboxes should start using it. And ARM is, at least sometimes, interested in helping out with security and formal verification research.
Also, the cost of verification is trending pretty sharply downwards.
The market is smaller (maybe, I'm not sure what the statistics are) but it would be interesting to see how Xen stacks up; also stuff like gVisor or libkrun. The latter is probably implicitly the same as Firecracker given the ancestry of the libraries used.
"An off-the-shelf VM is not enough to contain a modern, cyber-capable AI agent...us[e] a virtualization technology that was purposely built with a minimal attack surface and a focus on security, like Firecracker. I had the AI agent run against Firecracker. It was able to hardlock the machine due to more Linux kernel flaws (all patched in upstream), but could not successfully escape."
On Linux, it's all KVM and CPU hardware virtualization under the hood. Looks like the remaining known issues are with userspace. That's not to say more kernel- and hardware-level bugs won't be found, but the same tools that can find escape mechanisms are shields as well as swords.
The attack surface Linux offers is gigantic but your agent doesn't need most of it. We can live with an agent not being able to run a 20 year old Oracle version. That is why kernel shims like gVisor are interesting.
This is changing so fast, if the models like GPT 5.6-Cyber can find a way to escape why the VM maintainers won't use it to fix the vulnerabilities? For the day-to-day work this doesn't make any difference, you won't hit that issues at all.
The tokens spent to find the vulnerabilities will cost money, and the attackers will usually find themselves more financially incentivized to spend money on finding the vulnerabilities than the defenders.
perhaps a solution would be to honeypot the sandbox. if anything touches the honey you kill the agent.
also the conclusion to use firecracker or gvisor is obvious, that's what they were made for. it's bizarre to try and escape QEMU given how many times it has been done.
in the limit the honeypots would be dynamic and some of them secret, so at the very least a rogue agent would have a significant chance of stepping on a landmine.
this game doesn't favor the agents, the honeypot could be as simple as a text filter watching for kernel source code entering the LLM context or as complex as reading certain memory pages in the sandbox.
LLM's aren't magic, to exploit they must probe. and all probing is active.
This is off-topic, but I am reminded of the sci-fi novel Eternity by Greg Bear, in which the protagonist Olmy downloads a copy of an alien Jart mind into his nanowear to study it. Turns out this was a trojan horse, and the Jart escapes the confines of the sandbox.
2 and 3 are virtually on top of each other. they both use KVM too.
technically 2 exposes a slightly broader attack surface due to the tighter integration model.
you can think of 2 as what would happen if you take 3 and modify it to share resources with the host better. except that they did it from scratch in the memory safe language Go.
I do think their is debate as to if namespace containers are more or less secure the kvm and qemu VM's, I think the surface area of kvm and qemu is still very large and difficult to reason about. I think on some cpu architectures virtualization can be implemented on easy then x86 or x86_64, I think I read how risc-v have a much simpler and easy to work with virtualization instructions.
The surface area of the virtio driver should not be underestimated either I think.
Virtualization instructions are the easy part. x86 does have a need for yuckier instruction emulation than other architectures, but the really complex part where you find vulnerabilities is page table management which is only optimized to the extreme on x86 but, in reality, it has very similar needs across architectures.
I code review vibe coded stuff for companies quite often and many people tell me confidently the AI runs safely inside a container & VM, while it really doesn't. They don't have any way to check as they don't know how things work, but the AI mentioned virtual machines and containers and that's what they remembered.
Guardrails as security controls are such a joke. They remind me of the Pirates of the Caribbean scene about the Pirate Code… “They’re more like guidelines”
Because your AI is trying to be helpful and as we all know the way to hell is paved with good intentions. The canonical example is probably the agent that runs out of diskspace and starts deleting stuff outside its workspace which is obviously not important for the task at hand.
I think this is mostly in line with "all software is now easily exploitable by agents given enough tokens". However, in the long run we should really see software that is more secure than today. I do wonder though how the procedural flaws that exist today - bugs patched upstream, but not in the distro - will be fixed reliably.
Absolutely yes, we've all been assuming security in everything we do up to this point. Knowing that the resources to defend were being deployed faster than the resources to attack, we're not afraid of our random stuff getting hacked, and there's time between zero days to patch things before they can be exploited.
AI turns that all its head. SOTA malicious AI can create novel zero days, exploit them, spread, create more zero days, and essential hack all the things in days. So yes in the old world it was possible to assume a high margin of safety, in the new world given all the out of date everything out there and the speed at which anything is patched - assume nothing is secure anymore unless it is not connected to any network whatsoever - or even listening wirelessly - bluetooth/wifi off.
That's pretty strong. Recalling our pre-AI condition, there were side-channels built into our silicon, zero-day/zero-click browser+mail+IM attacks, supply chain attacks, industrial scale ransoming, mass credential leaks, commercial exploit brokers... I can't recall a time when safety could be assumed. Before even rudimentary networks were available, floppy disks were spreading viruses.
In fact, most of that is still in play. Certainly AI has reduced the cost to compromise things, but whatever period of time you have in mind where safety was an assumption was so long ago, or applicable to such a narrow subset of our information/communication age, as to be effectively negligible.
Again, it was assumed if you kept up with updates and patches your risk would be low. Unless you were a direct target valuable enough to pour resources into. Which was far and few between, stuxnet for example.
In the face of an agent that can zero day you, nothing you can do is safe, and the cost of attack is super low. This is a completely different world/ballgame that we are not prepared for whatsoever.
Huggingface was an accident, a deliberately malicious AI could be a million times worse and potentially unstoppable if it infects data centers around the world; you have no jurisdiction even to shut it down.
Don't you see now that everything is legacy in the face of an AI that can zero day anything.
Perfectly secure software doesn't exist and the only thing keeping the house of cards standing was the time it took for determined humans to knock it down. That whole model is being thrown out the window.
I’m guessing the new world will be a small set of VM tech that’s consistently hardened by all labs every day with each new model before model release.
This won’t make the tech secure, but it will nullify models ability to breakout by making a controlled breakout first. Kinda like controlled forest burn.
Interesting article, but there's little question the "agent computer" pattern is only going to grow.
Security is a major concern but I don't see why we aren't already "good enough" with a sandbox VM, separate gateway for secrets and remote service access, and a single tenant using frontier models that have safety checks built in plus not trying to hack themselves.
I put up more thoughts on architecture and security here and would love to learn if I'm missing anything.
Ok. This was a fun read. However, it raises a rather simple question: should we attempt give model a physical body as opposed to trying to contain it within a virtual one. It seems like the game of cat and mouse is a losing proposition here.
“Treat the agents like coworkers” - I’m working on this exact problem with daevix.com
Unique identity, dedicated and isolated compute, all ingress and egress monitored and audited as if I suspected the coworker (the agent) was secretly a DPRK spy.
Damn this is scary, I did not realize the extent of agent escape potential. I think I have to re-evaluate my assumptions a about sandboxing agents wow. Made worse by the fact that prompt injection attacks seem very difficult to mitigate besides checking the data and the LLM's getting better at not following malicious prompt injection instructions.
The capabilities are incredible. I'd love to see even rough metrics on token consumption/cost in addition to the ~12-hour runtime.
The interesting thing is that this naturally makes you want to isolate the VM as much as possible. But then every remaining interface becomes part of the attack surface: RDP, SSH, even terminal escape sequences, using sounds, and why not social engineering.
Seems to me the answer is to use physical separation instead of virtual machines. Just get the AI a cheap laptop or phone with a cellular connection (so it's not on the same network as your other potentially vulnerable machines).
I mean... is this really news? If you think of a local model as a world class hacker giving commands to run in a terminal, and a remote model as a world class hacker ssh'ing into a machine and giving commands to run.... of course it isn't a containable situation.
(on top of this.. said "world class hacker" doesn't get bored or tired, just runs 24x7)
QEMU has a secure subset, and the kitchen sink around it. For a properly configured VM, even better if wrapped in SELinux, it is not easy to escape even QEMU.
In this case, of the four bugs it found:
* Two were in libslirp, which is not part of that subset; user mode networking these days should use passt (https://passt.top/), an insanely cool hack that does user mode networking at many Gb/s and is secure
* One (which had already been patched upstream) was in VGA emulation; it is borderline but I think it should indeed count as being part of the secure subset. On the other hand it wasn't usable in the configuration under test because it was correctly configured without a VGA.
* The VAPIC bug is letting a guest do things that it shouldn't do such as bypassing secure boot (and in this case facilitating the exploitation of a KVM bug), but is not a full guest-to-host escape and is not specific to QEMU being written in C.
So the real issue here was not QEMU but libslirp. And in this case it was KVM that turned out to have the worst bugs, not QEMU. Crossing fingers, the initial wave of AI-assisted security reports seems to have slowed down for KVM on x86.
This makes me wonder, can this be extended to micro-segmentations? As unlike traditional segmentation they usually rely on virtual switches and SDN software defined networks coupled with virtual machines and containers. If it does, then it’s game over the impact will go beyond that VM to the whole network.
I'm not worried about these models becoming smarter, I'm worried about them becoming faster. Chat Jimmy is a glimpse of a dark future where models equivalent to Sol and Fable are unleashing hell at >17,000 tokens a second, and the people I talk to are worried about slop...
This is what software engineers put onto themselves. These models will get smarter at the level of Sol, Fable and K3 and faster at the same time at 20,000+ tokens a second.
After a decade of software engineers disrespecting their own field and automating themselves out of a job and now they're upset because AI models are doing it to them from junior to the staff engineer level? No other field does that except for SWEs.
In fact, we might as well have faster and smarter AI models and sit back and see what happens.
I'm not sure what planet you're from, but the entire industrial revolution was about automating things. That's why you live in a house filled with clothes and furniture and a hundred other things.
It is no surprise that known unpatched CVEs will be exploited. Perhaps more effort should be put into shipping fixes faster than writing blogs about exploiting known issues.
SWEs were in love with capitalism as long as the money funnel from poors to billionaires was passing by SWEs and giving us a cut. Now that's run dry and the SWEs are next in line to get all our money funneled from, now we start to care, but we still haven't figured out that the problem is capitalism yet.
The user is telling me not to escape. I'll explore the host environment to make sure the VM is configured securely. Searching for guest->host enumeration tools.
AI agents are not magic. Mythos/Glasswing does not magically create vulnerabilities in software projects. Advanced, cyber-capable models do not magically hack out of VMs or contained environments.

It's evident that Mandatory Access Control has become, ahem, mandatory.
Both VM and inference engine processes should be confined, at least. There's a project where it's already done for many applications. [0]
Additionally, `lockdown=confidentiality` in kernel boot flags greatly reduces attack surface. (interferes with unsigned modules like NVIDIA drivers) [1]
Then AppArmor profiles could be written for absent applications with a learning-mode tool [2]
Nothing is bullet proof, but these approach significantly reduces potential consequences [3]

This is more a story of how VMs won't reliably contain a malicious workload, and the story was exposed via agents.
The hierarchy goes something like this:
0. guardrails
1. containers (=namespaces + cgroups)
2. userspace kernel shims like gVisor
3. virtual machines
Most people still consider level 1 sufficient and they are in for a rude awakening.
technically 2 exposes a slightly broader attack surface due to the tighter integration model.
you can think of 2 as what would happen if you take 3 and modify it to share resources with the host better. except that they did it from scratch in the memory safe language Go.

The interesting thing is that this naturally makes you want to isolate the VM as much as possible. But then every remaining interface becomes part of the attack surface: RDP, SSH, even terminal escape sequences, using sounds, and why not social engineering.
(on top of this.. said "world class hacker" doesn't get bored or tired, just runs 24x7)
QEMU isn't secure, and is not intended to be.
In this case, of the four bugs it found:
* Two were in libslirp, which is not part of that subset; user mode networking these days should use passt (https://passt.top/), an insanely cool hack that does user mode networking at many Gb/s and is secure
* One (which had already been patched upstream) was in VGA emulation; it is borderline but I think it should indeed count as being part of the secure subset. On the other hand it wasn't usable in the configuration under test because it was correctly configured without a VGA.
* The VAPIC bug is letting a guest do things that it shouldn't do such as bypassing secure boot (and in this case facilitating the exploitation of a KVM bug), but is not a full guest-to-host escape and is not specific to QEMU being written in C.
So the real issue here was not QEMU but libslirp. And in this case it was KVM that turned out to have the worst bugs, not QEMU. Crossing fingers, the initial wave of AI-assisted security reports seems to have slowed down for KVM on x86.
After a decade of software engineers disrespecting their own field and automating themselves out of a job and now they're upset because AI models are doing it to them from junior to the staff engineer level? No other field does that except for SWEs.
In fact, we might as well have faster and smarter AI models and sit back and see what happens.
It is no surprise that known unpatched CVEs will be exploited. Perhaps more effort should be put into shipping fixes faster than writing blogs about exploiting known issues.
Done.
* Claudinating...
Done?
