Honest to goodness, I do most of my coding in a VM now. I don't see how the security profile of these things are tolerable. The level of potential hostility from agents as a malware vector is really off the charts. We're entering an era where they can scan for opportunities worth >$1,000 in hostaged data, crypto keys, passwords, blackmail material or financial records without even knowing what they're looking for when they breach a box.

    How does it avoid the sharing headaches that make the ergonomics of snaps so bad?
    - fsflover 1y ago
      I never used snaps, so I don't understand what you mean here. Here's a couple of typical Qubes usage patterns: https://www.qubes-os.org/news/2022/10/28/how-to-organize-your-qubes/ https://www.qubes-os.org/news/2022/10/28/how-to-organize-you..., https://blog.invisiblethings.org/2011/03/13/partitioning-my-digital-life-into.html https://blog.invisiblethings.org/2011/03/13/partitioning-my-...

        One of the biggest ones is around access to the home directory, ~/.whatever, that kind of thing. Like a browser downloads something, a text editor opens it, it gets run from the terminal and creates a new executable, that new executable is run and mutates something else that the text editor also had open, etc etc. If all the apps have access to ~ then it's https://xkcd.com/1200/ https://xkcd.com/1200/ and there's basically no point in the isolation, but if they each have their own ~ then sharing files between apps is a user-hostile headache. From that article, it looks like perhaps the difference is that snaps are isolated at the app level, whereas qubes is a layer down, where each qube is a kind of workspace with multiple apps potentially installed in it. That seems reasonable enough, though you do have to be willing to pay the disk and mental overhead cost associated with setting up the same tools multiple times, or maintain playbooks/whatever to automate that, or am I going to figure out how to get my one VSCode instance access to the different isolated environments where I need an editor, and if I do that have I basically compromised the whole system model.
        orblivion 1y ago
        The "Admin" of QubesOS (dom0) is in its own VM, and it doesn't have Internet access. Nothing you download from a browser in another VM can touch dom0 without a VM break. Each VM has its own file system. Even if you wanted to copy a downloaded file to dom0, Qubes makes you jump through hoops to do it.
        orblivion 1y ago
        As for setting things up multiple times - you can install stuff in the "Template VM" which is where the OS goes. Every "App VM" mostly just has files in their own ~/. Any changes an App VM makes to its system files won't affect other VMs, or even survive a restart. There are "playbooks" with Salt but I never figured that stuff out. If you pass around some setup scripts instead, that's an attack vector, but I don't think drive-by attacks like the OP would target something sophisticated like that yet.
  - orblivion 1y ago
    Yeah I use Qubes for my "serious" computing these days. It comes with performance headaches, though my laptop isn't the best. I wonder about something like https://secureblue.dev/ https://secureblue.dev/ though. I'm not comfortable with Fedora and last I heard it wasn't out of Beta or whatever yet. But it uses containers rather than VMs. I'm not a targeted person so I may be happy to have "good enough" security for some performance back.
    - secureblue 1y ago
      secureblue creator here :) some corrections: > last I heard it wasn't out of Beta or whatever yet It is > But it uses containers rather than VMs It doesn't use plain containers for app isolation. We ship the OS itself as a bootable container (https://github.com/bootc-dev/bootc https://github.com/bootc-dev/bootc). That doesn't mean we use or recommend using containers for application isolation. Container support is actually disabled by default via our selinux policy restricting userns usage (this can be toggled though, of course). Containers on their own don't provide sandboxing. The syscall filtering for them is extremely weak. Flatpak (which sandboxes via bubblewrap: https://github.com/containers/bubblewrap https://github.com/containers/bubblewrap) can be configured to be reasonably good, but we still encourage the use of VMs if needed. We provide one-click tooling for easily installing virt-manager (https://en.wikipedia.org/wiki/Virt-manager https://en.wikipedia.org/wiki/Virt-manager) if desired. In short though, secureblue and Qubes aren't really analogous. We have different goals and target use cases. There is even an open issue on Qubes to add a template to use secureblue as a guest: https://github.com/QubesOS/qubes-issues/issues/9755 https://github.com/QubesOS/qubes-issues/issues/9755
      - orblivion 1y ago
        I keep hearing different things about how well containers can isolate. I guess the "on their own" caveat is the important one. I don't really know how they work. Hearing not to rely on it from the developer of secureblue is pretty strong case. Thanks.

  Similar, but in a podman container which shares nothing other than the source code directory with my host machine.
  - evertheylen 1y ago
    I do too, but I found it non-trivial to actually secure the podman container. I described my approach here [1]. I'm very interested to hear your approach. Any specific podman flags or do you use another tool like toolbx/distrobox? [1]: https://evertheylen.eu/p/probox-intro/ https://evertheylen.eu/p/probox-intro/
    - christophilus 1y ago
      Very interesting. I learned some new things. I didn't know about `--userns` or the flexible "bind everything" network approach! Here's my script: https://codeberg.org/chrisdavies/dotfiles/src/branch/main/src/pod/pod.sh https://codeberg.org/chrisdavies/dotfiles/src/branch/main/sr... What I do is look for a `.podman` folder, and if it exists, I use the `env` file there to explicitly bind certain ports. That does mean I have to rebuild the container if I need to add a port, so I usually bind 2 ports, and that's generally good enough for my needs. I don't do any ssh in the container at all. I do that from the host. The nice thing about the `.podman` folder thing is that I can be anywhere in a subfolder, type `gg pod`, and it drops me into my container (at whatever path I last accessed within the container). No idea how secure my setup is, but I figure it's probably better than just running things unfettered on my dev box.
      - evertheylen 1y ago
        Yeah props to the `pasta` tool, it solves a specific problem really well. Nice script! I considered a similar approach that's based on "magic" files in the filesystem before, but it was difficult to get the security right. In your case I believe a malicious script can just overwrite .podman/env and it will be sourced by the host the next time you start the container. I'm happy to discuss this more, feel free to reach out at evertheylen@gmail.com. I'm particularly interested in trying automated ways to try to break out of a container (like https://github.com/brompwnie/botb https://github.com/brompwnie/botb), this would benefit any containerization project.
- sheerun 1y ago
  Exactly this, with note that due ecosystem and history of software, setting up such environment is either really hard or relatively expensive
- fph 1y ago
  Part of the problem is the traditional PC security model (Linux / Windows). "All the executable files I run are trusted and have access to all my personal files" doesn't work anymore in 2025. Android fixed this for the most part, but on PC SELinux is all we have and it's painful to use.

lol that prompt is actually pretty decent! Technical debt increase over the past few years is mind boggling to me. First the microservices, then the fuckton of CI/CD dependencies, and now add the AI slop on top with MCPs running in the back. Every day is a field day for security researchers. And where are all the new incredible products we were promised? Just goes to show that tools are just tools. No matter how much you throw at your product, if it sucks, it'll suck afterwards as well. Focus on the products, not the tools.

People really need to start thinking twice when adding a new dependency. So many supply chain attacks this year. This week, I needed to add a progress bar with 8 stats counters to my Go project. I looked at the libraries, and they all had 3000+ lines of code. I asked LLM to write me a simple progress report tracking UI, and it was less than 150 lines. It works as expected, no dependencies needed. It's extremely simple, and everyone can understand the code. It just clears the terminal output and redraws it every second. It is also thread-safe. Took me 25 minutes to integrate it and review the code. If you don't need a complex stats counter, a simple progress bar is like 30 lines of code as well. This is a way to go for me now when considering another dependency. We don't have the resources to audit every package update.
- croes 1y ago
  Without these dependencies there would be no training data so the AI can write your code
  - f311a 1y ago
    I could write it myself. It's trivial, just takes a bit more time, and googling escape sequences for the terminal to move the cursor and clear lines.
    - croes 1y ago
      And still you looked for a library first.
- wat10000 1y ago
  Part of the value proposition for bringing in outside libraries was: when they improve it, you get that automatically. Now the threat is: when they “improve” it, you get that automatically. left-pad should have been a major wake up call. Instead, the lesson people took away from it seems to have mostly been, “haha, look at those idiots pulling in an entire dependency for ten lines of code. I, on the other hand, am intelligent and thoughtful because I pull in dependencies for a hundred lines of code.”

the truly chilling part is using a local llm to find secrets. it's a new form of living off the land, where the malicious logic is in the prompt, not the code. this sidesteps most static analysis. the entry point is the same old post-install problem we've never fixed, but the payload is next-gen. how do you even defend against malicious prompts?

  Run Claude Code in a locked down container or VM that has no access to sensitive data, and review all of the code it commits?
  - myaccountonhn 1y ago
    As a separate locked-down user would probably also work.
  - spacebanana7 1y ago
    Conceivably couldn’t a post install script be used for the malicious dependency to install its own instance of Claude code (or similar tool)? In which case you couldn’t really separate your dev environment from a hostile LLM.
    - anon7000 1y ago
      Yes, though the attackers would have to pay for an account. In this case, it’s using a pre-installed, pre-authorized tool, using your own credits to hack you
    - christophilus 1y ago
      I run npm in the container, too, along with my dev tooling. They’d have to break out of the container, which I’m sure is possible, but is a good bit harder than just running an arbitrary nom script.

Google and Anthropic: this is a SEV0. Assemble your teams and immediately do the following: 1. Issue a public statement that you are aware of this issue and are tracking it 2. Begin monitoring your analytics to see which customers are impacted and shut down their access 3. Reach out to impacted customers and let them know you'll be preparing a list of next steps for them. 4. Monitor for a wider blast radius or larger attack surface area 5. Notify internal teams of broader security efforts as a result of this 6. After this cools down, hold internal and public postmortems. Do this now. Edit: -4 and flagged. I give up.

OSs need to stop letting applications have a free reign of all the files on the file system by default. Some apps come with apparmor/selinux profiles and firejail is also a solution. But the UX needs to change.
- terminalbraid 1y ago
  Which operating system lets an application have "free reign of all the files on the file system by default"? Neither Linux, nor any BSD, nor MacOS, nor Windows does. For any of those I'd have to do something deliberately unsafe such as running it as a privileged account (which is not the "default").

    I would argue the distinction between my own user and root is not meaningful when they say "all files by default". As my own user, it can still access everything I can on a daily basis which is likely everything of importance. Sure it can't replace the sudo binary or something like that, but it doesn't matter because it's already too late. Why when I download and run Firefox can it access every file my user can access, by default. Why couldn't it work a little closer to Android with an option for the user to open up more access. I think this is what they were getting at.

  Some AV / endpoint protection software could flag those files. Some corpo deep inspection software could flag those if downloaded / requested from the web.

  Furthermore most people have probably granted the node binary access to everything in their home directory on macOS. Other processes would pop up a permission dialog.
rvz 1y ago
That is really dire. Equivalent to a SEV0. Why would you allow AI agents like Anthropic and Gemini to have access to the user's filesystem? Basic security 101 requirements for these tools is that they should be sandboxed and have zero unattended access to the user's filesystem. Do software engineers building these agents in 2025 care about best practices anymore?
- datadrivenangel 1y ago
  The engineers who care haven't shipped yet because they see the risks.
cowpig 1y ago
I don't understand why people think it's a good idea to run coding agents as their own user on their own machines. I use this CLI tool for spinning up containers and attaching the local directory as a volume: https://github.com/Monadical-SAS/cubbi https://github.com/Monadical-SAS/cubbi It isn't perfect but it's a lot better than the alternative. Looked a lot at VM-based sandbox environments but by mounting the dir as a volume in the container, you can still do all of your normal stuff in your machine outside the container environment (editor, tools, etc), which in practice saves a lot of headache.

Pardon my ignorance, but isn’t code signing designed to stop attacks exactly like this? Even if an npm token was compromised, I’m really surprised there was no other code signing feature in play to prevent these publish events.
- bagels 1y ago
  Code signing just says that the code was blessed by someone's certificate who at one time showed an id to someone else. Nothing to do with whether the content being signed is malicious (at least on some platforms).

Claude code is by all accounts a revolutionary tool for getting useful work done on a computer. It's also: - a NodeJS app - installed by curling a shell script and piping it into bash - an LLM that's given free reign to mess with the filesystem, run commands, etc. So that's what, like 3 big glaring vectors of attack for your system right there? I would never feel comfortable running it outside of some kind of sandbox, e.g. VM, container, dedicated dev box, etc.
- kasey_junk 1y ago
  I definitely think running agents in sandboxes is the way to go. That said Claude code does not have free reign to run commands out of the gate.
  - sneak 1y ago
    Yes it does; you are thinking of agent tool calls. The software package itself runs as your uid and can do anything you can do (except on macOS where reading of certain directories is individually gated).
    - otterley 1y ago
      Claude Code is an agent. It will not call any tools or commands without your prior consent. Edit: unless you pass it an override like --dangerously-skip-permissions, as this malware does. https://www.stepsecurity.io/blog/supply-chain-security-alert-popular-nx-build-system-package-compromised-with-data-stealing-malware https://www.stepsecurity.io/blog/supply-chain-security-alert...
    - kasey_junk 1y ago
      Ok, but that’s true of _any_ program you install so isn’t interesting. I don’t think the current agent tool call permission model is _right_ but it exists, so saying by default it will freely run those calls is less true of agents than other programs you might run.

0xbadcafebee 1y ago
Before anyone puts the blame on Nx, or Anthropic, I would like to remind you all what actually caused this exploit. The exploit was caused by an exploit, shipped in a package, that was uploaded using a stolen "token" (a string of characters used as a sort of "usename+password" to access a programming-language package-manager repository). But that's just the delivery mechanism of the attack. What caused the attack to be successful were: 1. The package manager repository did not require signing of artifacts to verify they were generated by an authorized developer. 2. The package manager repository did not require code signing to verify the code was signed by an authorized developer. 3. (presumably) The package manager repository did not implement any heuristics to detect and prevent unusual activity (such as uploads coming from a new source IP or country). 4. (presumably) The package manager repository did not require MFA for the use of the compromised token. 5. (presumably) The token was not ephemeral. 6. (presumably) The developer whose token was stolen did not store the token in a password manager that requires the developer to manually authorize unsealing of the token by a new requesting application and session. Now after all those failures, if you were affected and a GitHub repo was created in your account, this is a failure of: 1. You to keep your GitHub tokens/auth in a password manager that requires you to manually authorize unsealing of the token by a new requesting application and session. So what really caused this exploit, is all completely preventable security mechanisms, that could have been easily added years ago by any competent programmer. The fact that they were not in place and mandatory is a fundamental failure of the entire software industry, because 1) this is not a new attack; it has been going on for years, and 2) we are software developers; there is nothing stopping us from fixing it. This is why I continue to insist there needs to be building codes for software, with inspections and fines for not following through. This attack could have been used on tens of thousands of institutions to bring down finance, power, telecommunications, hospitals, military, etc. And the scope of the attacks and their impact will only increase with AI. Clearly we are not responsible enough to write software safely and securely. So we must have a building code that forces us to do it safely and securely.

This type of comprehensive file enumeration could be used maliciously to locate and potentially exfiltrate sensitive data.

  Incredibly common W for Anthropic safeguards. In almost every case I see Claude go head-to-head on refusals with another model provider in a real-world scenario, Claude behaves and the other model doesn't. There was a viral case on Tiktok of some lady going through a mental health episode who was being enabled and referred to as "The Oracle" by ChatGPT, but when she swapped to Claude, Claude eventually refused and told her to speak to a professional. That's not to say the "That's absolutely right!" doesn't get annoying after a while, but we'd be doing everyone a disservice if we didn't reward Anthropic for paying more heed to safety and refusals than other labs.

Periodic reminder to disable npm install scripts. npm config set ignore-scripts true [--global] It's easy to do both at project level and globally, and these days there are quite few legit packages that don't work without them. For those that don't, you can create a separate installation script to your project that cds into that folder and runs their install-script. I know this isn't a silver bullet solution to supply chain attakcs, but, so far it has been effective against many attacks through npm. https://docs.npmjs.com/cli/v8/commands/npm-config https://docs.npmjs.com/cli/v8/commands/npm-config

  Can’t the exploit just be encoded in files that are used when the npm module is actually used? It seems like not running it at package install time doesn’t afford that much protection.
  - bapak 1y ago
    Correct. Pretty limited as a protection when the first thing you do after installing a package is running it. Literally the only thing blocking scripts protects you from is if a package is bundled by webpack and not run by node. If the compromise happens in nx, it's just run after up type nx[enter] in your command line.

    But you're still updating at some point. Usually to the latest version. If you're unlucky, you are the first victim, a few seconds after the package was published. (Edit: on a popular package there will always be a first victim somewhere in the first few minutes) Many of those supply chain attacks are detected within the first few hours, I guess nowadays there are even some companies out there, that run automated analysis on every new version of major packages. Also contributors/maintainers might notice something like that quickly, if they didn't plan that release and it suddenly appears.
- VPenkov 1y ago
  Not a package manager, but Renovate bot has a setting like that (minimumReleaseAge). Dependabot does not (Edit: does now). So while your package manager will install whatever is newest, there are free solutions to keep your dependencies up to date in a reasonable manner. Also, the javascript ecosystem seems to slowly be going in the direction of consolidation, and supply chain attacks are (again, slowly) getting tools to get addressed. Additionally, current versions of all major package managers (NPM, PNPM, Bun, I don't know about Yarn) don't automatically run postinstall scripts - although you are likely to run them anyway because they will be suggested to you - and ultimately you're running someone else's code, postinstall scripts or not.

I wonder if anyone use https://verdaccio.org/ https://verdaccio.org/ to vendor packages?

The main caveat I see is that it’s very inconvenient to have to vet and publish each package manually. It would be great if Verdaccio had a UI to make this easier, for example, showing packages that were attempted to install but not yet vetted, and then allowing approval with a single click.

I'm afraid that open source software supply chain attacks could be much more prevalent than what we are currently aware of. There is a significant market for zero-day exploits, with organizations like the NSA having teams dedicated to collecting and weaponizing them. But finding and exploiting an unintentional zero-day vulnerability is way more difficult than adding an intentional exploitable bug or backdoor to some of the myriad widely used open source dependencies. Of course, if you do it right, you don't land on the HN front page.
- xmodem 1y ago
  Every time one of these comes up, I have similar thoughts. A threat actor is in the position to pull off a large-scale supply chain compromise, and the best thing you can think of to do with that is also the thing that will guarantee you are discovered immediately? Mine crypto on the damn CPU, or publicly post the victim's credentials to their own GitHub account? On one hand, I cannot accept that the actors that we see who pull these off are the best and brightest. My gut tells me that these attacks must be happening in more subtle ways from time to time. Maybe they're more targeted, maybe they're not but just have more subtle exfil mechanisms. On the other, well we have exactly one data point of an attempt at a more subtle attack. And it was thwarted right before it started to see wide-spread distribution. But also there was a significant amount of luck involved. And what if it hadn't been discovered? We'd still have zero data points, but some unknown actor would possess an SSH skeleton key. So I don't know what to think.

  Use as few deps as possible, and run your projects in containers, or even better, VMs.
  - neya 1y ago
    That doesn't guarantee anything still, that's the beauty of Javascript ;)
aloer 1y ago
There is a lot of discussion in the comments about using VMs for dev work. I too try to at least use containers whenever I can but it's sometimes not very practical. Better than nothing. 99% of the threat model is software trying to extract data. Either for myself (e.g. blackmail) or to learn about me and attack others (impersonation for scams, fraud, blackmail against others) or to access systems I have access to (tokens, API keys, online banking) Currently I am playing around with local LLMs on a Mac. The whole field is moving so fast that it is impossible not to rely on recent releases to quickly try new features. Unfortunately there is no way to access the Mac GPU in VMs. So right now to have at least a tiny bit of separation I have the local LLM tools set up on a separate local Mac user that I can then ssh into and use to expose a web server usable from my main (dev) account. This of course is far from perfect but at least a little better than before. I fully expect supply chain attacks on AI tooling and perhaps even malicious LLM models to happen at some point. That target is too juicy. Setting this up I was a bit irritated by some of the defaults of macos for multi user setups. - All mac software is usually installed to the global /Applications folder. Homebrew needs a workaround to work across multiple users - By default all files of a local mac user can be read by all other non admin local mac users. Only Apple-created folders like Documents, Desktop etc. are locked down If you want to store files outside of those Apple-created folders, perhaps because you sync Documents with icloud and want to store project repos and larger files, perhaps because you have ssh and github configs, dotfiles etc. in your home dir, then they are all by default readable by other non admin users. This is not to say that this is a huge issue that can't be fixed (just need to remove default permissions for group 'staff' yourself) but it is interesting that this is the default. The concept of multiple local users seems to be completely ignored by users and by Apple, and has been mostly unchanged for decades. There are tiny improvements such as Apples permissions dialog when an application accesses Desktop, Documents or Downloads for the first time. But this seems pretty useless all things considered. Why is it not more common to have stronger local separation? I don't need and don't want total iOS-level sandboxing (and lack of file system) but why isn't there a little more progress on the computer side of things? I agree that VM-level isolation with good usability and little performance loss would be a great thing. But this is aiming for perfection in a world pressured by more and more supply chain attacks as well as more automated (read: AI controlled) computer use. As an 80% "OS-native" solution it would be great if I could easily use local users for different project files _and_ stream GUIs across users (to work seamlessly from one main account). Then we could probably avoid the majority of security risks in every day computer use for developers and other "computer workers" alike. -- I skipped over that last part but this is the real blocker. It should be possible by now to easily stream a "remote" (local, different user) application UI into my current users window management with full support for my many screens, resolutions, copy/paste and shortcuts. All while having zero quality loss or performance overhead if done locally. I don't want remote desktop, I want remote application UI. This is not a new idea (X11 forwarding) Here's a fun thought: AI workflows and agents have surprised us all. We see them clicking and typing and changing files on our machines. If the OS-makers don't come up with appropriate mechanisms then we will somehow end up recreating a new form of OS. It is already starting with AI-focussed browsers or ChatGPT as an entry point to delegate "browse the web for me". It will be web based with compute happening on VMs in the background, probably billed like a SaaS and disappoint all of us wanting to preserve the ideal of personal computers. Eventually it will make desktop OS's irrelevant and we all end up working with a form of chromebook

Supply chain attacks on developer tools are getting more sophisticated. This hits every project using these plugins. The scary part is how long malicious packages can sit undetected. Your CI/CD pipeline could be compromised for months before anyone notices. This is why I always say to scan all dependencies in your compliance checks - not just for known vulnerabilities, but for unexpected changes in package behavior. When a routine update starts making network calls it never made before, that's a red flag.

Honest to goodness, I do most of my coding in a VM now. I don't see how the security profile of these things are tolerable. The level of potential hostility from agents as a malware vector is really off the charts. We're entering an era where they can scan for opportunities worth >$1,000 in hostaged data, crypto keys, passwords, blackmail material or financial records without even knowing what they're looking for when they breach a box.

      One of the biggest ones is around access to the home directory, ~/.whatever, that kind of thing. Like a browser downloads something, a text editor opens it, it gets run from the terminal and creates a new executable, that new executable is run and mutates something else that the text editor also had open, etc etc. If all the apps have access to ~ then it's https://xkcd.com/1200/ https://xkcd.com/1200/ and there's basically no point in the isolation, but if they each have their own ~ then sharing files between apps is a user-hostile headache. From that article, it looks like perhaps the difference is that snaps are isolated at the app level, whereas qubes is a layer down, where each qube is a kind of workspace with multiple apps potentially installed in it. That seems reasonable enough, though you do have to be willing to pay the disk and mental overhead cost associated with setting up the same tools multiple times, or maintain playbooks/whatever to automate that, or am I going to figure out how to get my one VSCode instance access to the different isolated environments where I need an editor, and if I do that have I basically compromised the whole system model.
      - orblivion 1y ago
        The "Admin" of QubesOS (dom0) is in its own VM, and it doesn't have Internet access. Nothing you download from a browser in another VM can touch dom0 without a VM break. Each VM has its own file system. Even if you wanted to copy a downloaded file to dom0, Qubes makes you jump through hoops to do it.
      - orblivion 1y ago
        As for setting things up multiple times - you can install stuff in the "Template VM" which is where the OS goes. Every "App VM" mostly just has files in their own ~/. Any changes an App VM makes to its system files won't affect other VMs, or even survive a restart. There are "playbooks" with Salt but I never figured that stuff out. If you pass around some setup scripts instead, that's an attack vector, but I don't think drive-by attacks like the OP would target something sophisticated like that yet.
- orblivion 1y ago
  Yeah I use Qubes for my "serious" computing these days. It comes with performance headaches, though my laptop isn't the best. I wonder about something like https://secureblue.dev/ https://secureblue.dev/ though. I'm not comfortable with Fedora and last I heard it wasn't out of Beta or whatever yet. But it uses containers rather than VMs. I'm not a targeted person so I may be happy to have "good enough" security for some performance back.
  - secureblue 1y ago
    secureblue creator here :) some corrections: > last I heard it wasn't out of Beta or whatever yet It is > But it uses containers rather than VMs It doesn't use plain containers for app isolation. We ship the OS itself as a bootable container (https://github.com/bootc-dev/bootc https://github.com/bootc-dev/bootc). That doesn't mean we use or recommend using containers for application isolation. Container support is actually disabled by default via our selinux policy restricting userns usage (this can be toggled though, of course). Containers on their own don't provide sandboxing. The syscall filtering for them is extremely weak. Flatpak (which sandboxes via bubblewrap: https://github.com/containers/bubblewrap https://github.com/containers/bubblewrap) can be configured to be reasonably good, but we still encourage the use of VMs if needed. We provide one-click tooling for easily installing virt-manager (https://en.wikipedia.org/wiki/Virt-manager https://en.wikipedia.org/wiki/Virt-manager) if desired. In short though, secureblue and Qubes aren't really analogous. We have different goals and target use cases. There is even an open issue on Qubes to add a template to use secureblue as a guest: https://github.com/QubesOS/qubes-issues/issues/9755 https://github.com/QubesOS/qubes-issues/issues/9755
    - orblivion 1y ago
      I keep hearing different things about how well containers can isolate. I guess the "on their own" caveat is the important one. I don't really know how they work. Hearing not to rely on it from the developer of secureblue is pretty strong case. Thanks.

    Very interesting. I learned some new things. I didn't know about `--userns` or the flexible "bind everything" network approach! Here's my script: https://codeberg.org/chrisdavies/dotfiles/src/branch/main/src/pod/pod.sh https://codeberg.org/chrisdavies/dotfiles/src/branch/main/sr... What I do is look for a `.podman` folder, and if it exists, I use the `env` file there to explicitly bind certain ports. That does mean I have to rebuild the container if I need to add a port, so I usually bind 2 ports, and that's generally good enough for my needs. I don't do any ssh in the container at all. I do that from the host. The nice thing about the `.podman` folder thing is that I can be anywhere in a subfolder, type `gg pod`, and it drops me into my container (at whatever path I last accessed within the container). No idea how secure my setup is, but I figure it's probably better than just running things unfettered on my dev box.
    - evertheylen 1y ago
      Yeah props to the `pasta` tool, it solves a specific problem really well. Nice script! I considered a similar approach that's based on "magic" files in the filesystem before, but it was difficult to get the security right. In your case I believe a malicious script can just overwrite .podman/env and it will be sourced by the host the next time you start the container. I'm happy to discuss this more, feel free to reach out at evertheylen@gmail.com. I'm particularly interested in trying automated ways to try to break out of a container (like https://github.com/brompwnie/botb https://github.com/brompwnie/botb), this would benefit any containerization project.

People really need to start thinking twice when adding a new dependency. So many supply chain attacks this year. This week, I needed to add a progress bar with 8 stats counters to my Go project. I looked at the libraries, and they all had 3000+ lines of code. I asked LLM to write me a simple progress report tracking UI, and it was less than 150 lines. It works as expected, no dependencies needed. It's extremely simple, and everyone can understand the code. It just clears the terminal output and redraws it every second. It is also thread-safe. Took me 25 minutes to integrate it and review the code. If you don't need a complex stats counter, a simple progress bar is like 30 lines of code as well. This is a way to go for me now when considering another dependency. We don't have the resources to audit every package update.

Without these dependencies there would be no training data so the AI can write your code
- f311a 1y ago
  I could write it myself. It's trivial, just takes a bit more time, and googling escape sequences for the terminal to move the cursor and clear lines.
  - croes 1y ago
    And still you looked for a library first.
wat10000 1y ago
Part of the value proposition for bringing in outside libraries was: when they improve it, you get that automatically. Now the threat is: when they “improve” it, you get that automatically. left-pad should have been a major wake up call. Instead, the lesson people took away from it seems to have mostly been, “haha, look at those idiots pulling in an entire dependency for ten lines of code. I, on the other hand, am intelligent and thoughtful because I pull in dependencies for a hundred lines of code.”

the truly chilling part is using a local llm to find secrets. it's a new form of living off the land, where the malicious logic is in the prompt, not the code. this sidesteps most static analysis. the entry point is the same old post-install problem we've never fixed, but the payload is next-gen. how do you even defend against malicious prompts?

  Conceivably couldn’t a post install script be used for the malicious dependency to install its own instance of Claude code (or similar tool)? In which case you couldn’t really separate your dev environment from a hostile LLM.

    Yes, though the attackers would have to pay for an account. In this case, it’s using a pre-installed, pre-authorized tool, using your own credits to hack you

    I run npm in the container, too, along with my dev tooling. They’d have to break out of the container, which I’m sure is possible, but is a good bit harder than just running an arbitrary nom script.

Google and Anthropic: this is a SEV0. Assemble your teams and immediately do the following: 1. Issue a public statement that you are aware of this issue and are tracking it 2. Begin monitoring your analytics to see which customers are impacted and shut down their access 3. Reach out to impacted customers and let them know you'll be preparing a list of next steps for them. 4. Monitor for a wider blast radius or larger attack surface area 5. Notify internal teams of broader security efforts as a result of this 6. After this cools down, hold internal and public postmortems. Do this now. Edit: -4 and flagged. I give up.

OSs need to stop letting applications have a free reign of all the files on the file system by default. Some apps come with apparmor/selinux profiles and firejail is also a solution. But the UX needs to change.

terminalbraid 1y ago
Which operating system lets an application have "free reign of all the files on the file system by default"? Neither Linux, nor any BSD, nor MacOS, nor Windows does. For any of those I'd have to do something deliberately unsafe such as running it as a privileged account (which is not the "default").

  I would argue the distinction between my own user and root is not meaningful when they say "all files by default". As my own user, it can still access everything I can on a daily basis which is likely everything of importance. Sure it can't replace the sudo binary or something like that, but it doesn't matter because it's already too late. Why when I download and run Firefox can it access every file my user can access, by default. Why couldn't it work a little closer to Android with an option for the user to open up more access. I think this is what they were getting at.

That is really dire. Equivalent to a SEV0. Why would you allow AI agents like Anthropic and Gemini to have access to the user's filesystem?

I don't understand why people think it's a good idea to run coding agents as their own user on their own machines. I use this CLI tool for spinning up containers and attaching the local directory as a volume: https://github.com/Monadical-SAS/cubbi https://github.com/Monadical-SAS/cubbi It isn't perfect but it's a lot better than the alternative. Looked a lot at VM-based sandbox environments but by mounting the dir as a volume in the container, you can still do all of your normal stuff in your machine outside the container environment (editor, tools, etc), which in practice saves a lot of headache.

Pardon my ignorance, but isn’t code signing designed to stop attacks exactly like this? Even if an npm token was compromised, I’m really surprised there was no other code signing feature in play to prevent these publish events.

Claude code is by all accounts a revolutionary tool for getting useful work done on a computer. It's also: - a NodeJS app - installed by curling a shell script and piping it into bash - an LLM that's given free reign to mess with the filesystem, run commands, etc. So that's what, like 3 big glaring vectors of attack for your system right there? I would never feel comfortable running it outside of some kind of sandbox, e.g. VM, container, dedicated dev box, etc.

kasey_junk 1y ago
I definitely think running agents in sandboxes is the way to go. That said Claude code does not have free reign to run commands out of the gate.

  Yes it does; you are thinking of agent tool calls. The software package itself runs as your uid and can do anything you can do (except on macOS where reading of certain directories is individually gated).
  - otterley 1y ago
    Claude Code is an agent. It will not call any tools or commands without your prior consent.

    Ok, but that’s true of _any_ program you install so isn’t interesting. I don’t think the current agent tool call permission model is _right_ but it exists, so saying by default it will freely run those calls is less true of agents than other programs you might run.

Before anyone puts the blame on Nx, or Anthropic, I would like to remind you all what actually caused this exploit. The exploit was caused by an exploit, shipped in a package, that was uploaded using a stolen "token" (a string of characters used as a sort of "usename+password" to access a programming-language package-manager repository). But that's just the delivery mechanism of the attack. What caused the attack to be successful were: 1. The package manager repository did not require signing of artifacts to verify they were generated by an authorized developer. 2. The package manager repository did not require code signing to verify the code was signed by an authorized developer. 3. (presumably) The package manager repository did not implement any heuristics to detect and prevent unusual activity (such as uploads coming from a new source IP or country). 4. (presumably) The package manager repository did not require MFA for the use of the compromised token. 5. (presumably) The token was not ephemeral. 6. (presumably) The developer whose token was stolen did not store the token in a password manager that requires the developer to manually authorize unsealing of the token by a new requesting application and session. Now after all those failures, if you were affected and a GitHub repo was created in your account, this is a failure of: 1. You to keep your GitHub tokens/auth in a password manager that requires you to manually authorize unsealing of the token by a new requesting application and session. So what really caused this exploit, is all completely preventable security mechanisms, that could have been easily added years ago by any competent programmer. The fact that they were not in place and mandatory is a fundamental failure of the entire software industry, because 1) this is not a new attack; it has been going on for years, and 2) we are software developers; there is nothing stopping us from fixing it. This is why I continue to insist there needs to be building codes for software, with inspections and fines for not following through. This attack could have been used on tens of thousands of institutions to bring down finance, power, telecommunications, hospitals, military, etc. And the scope of the attacks and their impact will only increase with AI. Clearly we are not responsible enough to write software safely and securely. So we must have a building code that forces us to do it safely and securely.

Incredibly common W for Anthropic safeguards. In almost every case I see Claude go head-to-head on refusals with another model provider in a real-world scenario, Claude behaves and the other model doesn't. There was a viral case on Tiktok of some lady going through a mental health episode who was being enabled and referred to as "The Oracle" by ChatGPT, but when she swapped to Claude, Claude eventually refused and told her to speak to a professional. That's not to say the "That's absolutely right!" doesn't get annoying after a while, but we'd be doing everyone a disservice if we didn't reward Anthropic for paying more heed to safety and refusals than other labs.

Periodic reminder to disable npm install scripts. npm config set ignore-scripts true [--global] It's easy to do both at project level and globally, and these days there are quite few legit packages that don't work without them. For those that don't, you can create a separate installation script to your project that cds into that folder and runs their install-script. I know this isn't a silver bullet solution to supply chain attakcs, but, so far it has been effective against many attacks through npm. https://docs.npmjs.com/cli/v8/commands/npm-config https://docs.npmjs.com/cli/v8/commands/npm-config

  Correct. Pretty limited as a protection when the first thing you do after installing a package is running it. Literally the only thing blocking scripts protects you from is if a package is bundled by webpack and not run by node.

  But you're still updating at some point. Usually to the latest version. If you're unlucky, you are the first victim, a few seconds after the package was published. (Edit: on a popular package there will always be a first victim somewhere in the first few minutes) Many of those supply chain attacks are detected within the first few hours, I guess nowadays there are even some companies out there, that run automated analysis on every new version of major packages. Also contributors/maintainers might notice something like that quickly, if they didn't plan that release and it suddenly appears.
VPenkov 1y ago
Not a package manager, but Renovate bot has a setting like that (minimumReleaseAge). Dependabot does not (Edit: does now). So while your package manager will install whatever is newest, there are free solutions to keep your dependencies up to date in a reasonable manner. Also, the javascript ecosystem seems to slowly be going in the direction of consolidation, and supply chain attacks are (again, slowly) getting tools to get addressed. Additionally, current versions of all major package managers (NPM, PNPM, Bun, I don't know about Yarn) don't automatically run postinstall scripts - although you are likely to run them anyway because they will be suggested to you - and ultimately you're running someone else's code, postinstall scripts or not.

The main caveat I see is that it’s very inconvenient to have to vet and publish each package manually.

I'm afraid that open source software supply chain attacks could be much more prevalent than what we are currently aware of. There is a significant market for zero-day exploits, with organizations like the NSA having teams dedicated to collecting and weaponizing them. But finding and exploiting an unintentional zero-day vulnerability is way more difficult than adding an intentional exploitable bug or backdoor to some of the myriad widely used open source dependencies. Of course, if you do it right, you don't land on the HN front page.

xmodem 1y ago
Every time one of these comes up, I have similar thoughts. A threat actor is in the position to pull off a large-scale supply chain compromise, and the best thing you can think of to do with that is also the thing that will guarantee you are discovered immediately? Mine crypto on the damn CPU, or publicly post the victim's credentials to their own GitHub account? On one hand, I cannot accept that the actors that we see who pull these off are the best and brightest. My gut tells me that these attacks must be happening in more subtle ways from time to time. Maybe they're more targeted, maybe they're not but just have more subtle exfil mechanisms. On the other, well we have exactly one data point of an attempt at a more subtle attack. And it was thwarted right before it started to see wide-spread distribution. But also there was a significant amount of luck involved. And what if it hadn't been discovered? We'd still have zero data points, but some unknown actor would possess an SSH skeleton key. So I don't know what to think.

aloer 1y ago

There is a lot of discussion in the comments about using VMs for dev work. I too try to at least use containers whenever I can but it's sometimes not very practical. Better than nothing. 99% of the threat model is software trying to extract data. Either for myself (e.g. blackmail) or to learn about me and attack others (impersonation for scams, fraud, blackmail against others) or to access systems I have access to (tokens, API keys, online banking) Currently I am playing around with local LLMs on a Mac. The whole field is moving so fast that it is impossible not to rely on recent releases to quickly try new features. Unfortunately there is no way to access the Mac GPU in VMs. So right now to have at least a tiny bit of separation I have the local LLM tools set up on a separate local Mac user that I can then ssh into and use to expose a web server usable from my main (dev) account. This of course is far from perfect but at least a little better than before. I fully expect supply chain attacks on AI tooling and perhaps even malicious LLM models to happen at some point. That target is too juicy. Setting this up I was a bit irritated by some of the defaults of macos for multi user setups. - All mac software is usually installed to the global /Applications folder. Homebrew needs a workaround to work across multiple users - By default all files of a local mac user can be read by all other non admin local mac users. Only Apple-created folders like Documents, Desktop etc. are locked down If you want to store files outside of those Apple-created folders, perhaps because you sync Documents with icloud and want to store project repos and larger files, perhaps because you have ssh and github configs, dotfiles etc. in your home dir, then they are all by default readable by other non admin users. This is not to say that this is a huge issue that can't be fixed (just need to remove default permissions for group 'staff' yourself) but it is interesting that this is the default. The concept of multiple local users seems to be completely ignored by users and by Apple, and has been mostly unchanged for decades. There are tiny improvements such as Apples permissions dialog when an application accesses Desktop, Documents or Downloads for the first time. But this seems pretty useless all things considered. Why is it not more common to have stronger local separation? I don't need and don't want total iOS-level sandboxing (and lack of file system) but why isn't there a little more progress on the computer side of things? I agree that VM-level isolation with good usability and little performance loss would be a great thing. But this is aiming for perfection in a world pressured by more and more supply chain attacks as well as more automated (read: AI controlled) computer use. As an 80% "OS-native" solution it would be great if I could easily use local users for different project files _and_ stream GUIs across users (to work seamlessly from one main account). Then we could probably avoid the majority of security risks in every day computer use for developers and other "computer workers" alike. -- I skipped over that last part but this is the real blocker. It should be possible by now to easily stream a "remote" (local, different user) application UI into my current users window management with full support for my many screens, resolutions, copy/paste and shortcuts. All while having zero quality loss or performance overhead if done locally. I don't want remote desktop, I want remote application UI. This is not a new idea (X11 forwarding) Here's a fun thought: AI workflows and agents have surprised us all. We see them clicking and typing and changing files on our machines. If the OS-makers don't come up with appropriate mechanisms then we will somehow end up recreating a new form of OS. It is already starting with AI-focussed browsers or ChatGPT as an entry point to delegate "browse the web for me". It will be web based with compute happening on VMs in the background, probably billed like a SaaS and disappoint all of us wanting to preserve the ideal of personal computers. Eventually it will make desktop OS's irrelevant and we all end up working with a form of chromebook

Interesting they create a public repo in your GitHub to store the payload. I would have thought would be better and less obvious to just upload the payload to a server they control.

NodeJS was/is/and always will be satanism anyway.

I observed a VS Code plugin compromise itself after running: "npx exec nx@latest --version". Is it really that easy to get infected, or am I missing a more dangerous step it took? If this behavior is common, doesn’t it mean you could be exposed even without using a vulnerable plugin version, since it auto-runs @latest scripts just to check the version?

The same thing that happend to grafana? https://grafana.com/blog/2025/05/15/grafana-security-update-post-incident-review-for-github-workflow-vulnerability-and-whats-next/ https://grafana.com/blog/2025/05/15/grafana-security-update-...

Supply chain attacks on developer tools are getting more sophisticated. This hits every project using these plugins. The scary part is how long malicious packages can sit undetected. Your CI/CD pipeline could be compromised for months before anyone notices. This is why I always say to scan all dependencies in your compliance checks - not just for known vulnerabilities, but for unexpected changes in package behavior. When a routine update starts making network calls it never made before, that's a red flag.

There is a low hanging fruit in making GitHub Actions more secure (anyone from GitHub here?): - Forbid (or at least warn about) shell interpolation in composite actions and guide to using environment variables instead - Warn unless all external actions are pinned by git commit (with customizable exceptions) - Warn unless all used docker images are pinned by digests

The impact of this was huge.
