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.
Or use pnpm. The latest versions have all dependency lifecycle scripts ignored by default. You must whitelist each package.

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.

> People really need to start thinking twice when adding a new dependency. So many supply chain attacks this year.
I was really nervous when "language package managers" started to catch on. I work in the systems programming world, not the web world, so for the past decade, I looked from a distance at stuff like pip and npm and whatever with kind of a questionable side-eye. But when I did a Rust project and saw how trivially easy it was to pull in dozens of completely un-reviewed dependencies from the Internet with Cargo via a single line in a config file, I knew we were in for a bad time. Sure enough. This is a bad direction, and we need to turn back now. (We won't. There is no such thing as computer security.)
skydhash · 1h ago
The thing is, system based package managers require discipline, especially from library authors. Even in the web world, it’s really distressing when you see a minor library is already on its 15 iteration in less that 5 years.
I was trying to build just (the task runner) on Debian 12 and it was impossible. It kept complaining about rust version, then some libraries shenanigans. It is way easier to build Emacs and ffmpeg.
rootnod3 · 1h ago
Fully agree. That is why I vendor all my dependencies. On the common lisp side a new tool emerged a while ago for that[1].
On top of that, I try to keep the dependencies to an absolute minimum. In my current project it's 15 dependencies, including the sub-dependencies.
I didn't vendor them, but I did do an eyeball scan of every package in the full tree for my project, primarily to gather their license requirements[1]. (This was surprisingly difficult for something that every project in theory must do to meet licensing requirements!) It amounted to approximately 50 dependencies pulled into the build, to create a single gstreamer plugin. Not a fan.
Vendoring is nice. Using the system version is nicer. If you can’t run on $current_debian, that’s very much a you problem. If postgres and nginx can do it, you can too.
exDM69 · 46m ago
The system package manager and the language package/dependency managers do a very different task.
The distro package manager delivers applications (like Firefox) and a coherent set of libraries needed to run those applications.
Most distro package managers (except Nix and its kin) don't allow you to install multiple versions of a library, have libs with different compile time options enabled (or they need separate packages for that). Once you need a different version of some library than, say, Firefox does, you're out of luck.
A language package manager by contrast delivers your dependency graph, pinned to certain versions you control, to build your application. It can install many different versions of a lib, possibly even link them in the same application.
skydhash · 28m ago
But I don’t really want your version of the application, I want the one that is aligned to my system. If some feature is really critical to the application, you can detect them at runtime and bailout (in C at least). Most developers are too aggressive on version pinning.
> Most distro package managers (except Nix and its kin) don't allow you to install multiple versions of a library
They do, but most distro only supports one or two versions in the official repos.
coldpie · 46m ago
> If you can’t run on $current_debian, that’s very much a you problem.
This is a reasonable position for most software, but definitely not all, especially when you fix a bug or add a feature in your dependent library and your Debian users (reasonably!) don't want to wait months or years for Debian to update their packages to get the benefits. This probably happens rarely for stable system software like postgres and nginx, but for less well-established usecases like running modern video games on Linux, it definitely comes up fairly often.
rootnod3 · 52m ago
But that would lock me in to say whatever $debian provides. And some dependencies only exist as source because they are not packaged for $distribution.
Of course, if possible, just saying "hey, I need these dependencies from the system" is nicer, but also not error-free. If a system suddenly uses an older or newer version of a dependency, you might also run into trouble.
In either case, you run into either an a) trust problem or b) a maintenance problem. And in that scenario I tend to prefer option b), at least I know exactly whom to blame and who is in charge of fixing it: me.
Also comes down to the language I guess. Common Lisp has a tendency to use source packages anyway.
cedws · 1h ago
Rust makes me especially nervous due to the possibility of compile-time code execution. So a cargo build invocation is all it could take to own you. In Go there is no such possibility by design.
exDM69 · 55m ago
The same applies to any Makefile, the Python script invoked by CMake or pretty much any other scriptable build system. They are all untrusted scripts you download from the internet and run on your computer. Rust build.rs is not really special in that regard.
Maybe go build doesn't allow this but most other language ecosystems share the same weakness.
cedws · 45m ago
Yes but it's the fact that cargo can pull a massive unreviewed dependency tree and then immediately execute code from those dependencies that's the problem. If you have a repo with a Makefile you have the opportunity to review it first at least.

In JavaScript just the npm install can fuck things up. Pre-install scripts can run malicious code.
So many people are so drunk on the kool aid, I often wonder if I’m the weirdo for not wanting dozens of third party libraries just to build a simple HTTP client for a simple internal REST api. (No I don’t want tokio, Unicode, multipart forms, SSL, web sockets, …). At least Rust has “features”. With pip and such, avoiding the kitchen sink is not an option.
I also find anything not extensively used has bugs or missing features I need. It’s easier to fork/replace a lot of simple dependencies than hope the maintainer merges my PR on a timeline convenient for my work.

If you don’t want Tokio I have bad news for you. Rust doesn’t ship an asynchronous runtime. So you’ll need something if you want to run async.

There is only one Rust application (server) I use enough that I try to keep up and rebuild it from the latest release every now and then. Most of the time new releases mostly bump versions of some of the 200 or so dependencies. I have no idea how I, or the server code's maintainers, can have any clue what exactly is brought in with each release. How many upgrades times 200 projects before there is a near 100% chance of something bad being included?
The ideal number of both dependencies and releases are zero. That is the only way to know nothing bad was added. Sadly much software seems to push for MORE, not fewer, of both. Languages and libraries keep changing their APIs , forcing cascades of unnecessary changes to everything. It's like we want supply chain attacks to hurt as much as possible.

I’d like a package manager that essentially does a git clone, and a culture that says: “use very few dependencies, commit their source code in your repo, and review any changes when you do an update.” That would be a big improvement to the modern package management fiasco.

Is that realistic though? What you're proposing is letting go of abstractions completely.
Say you need compression, you're going to review changes in the compression code?
What about encryption, a networking library, what about the language you're using itself?
That means you need to be an expert on everything you run. Which means no one will be building anything non trivial.

My point was that git clone of the source can't be the solution, or you own all the code... And you can't. You always depend on something....
k3nx · 19m ago
That what I used git submodules for. I had a /lib folder in my project where the dependencies were pulled/checked out from. This was before I was doing CI/CD and before folks said git submodules were bad.
Personally, I loved it. I only looked and updating them when I was going to release a new version of my program. I could easily do a diff to see what changed. I might not have understood everything, but it wasn't too difficult to see 10-100 line code changes to get a general idea.
I thought it was better than the big black box we currently deal with. Oh, this package uses this package, and this package... what's different? No idea now, really.

We are using NX heavily (and are not affected) in my teams in a larger insurance company.

I've toyed with other monorepo tools for these kind of complex setup in my career (lerna, rushjs, yarn workspaces) but not only did none came close, lerna is basically handed over to NX, and rushjs is unmaintained.
If you have any proposal how to properly manage the complexity of a FE monorepo with dozens of daily developers involved and heavy CI/CD/Devops integration, please post alternatives - given that security incident many people are looking.

npm workspaces and npm scripts will get you further than you might think. Plenty of people got along fine with Lerna, which didn't do much more than that, for years.
I will say, I was always turned off by NX's core proposition when it launched, and more turned off by whatever they're selling as a CI/CD solution these days, but if it works for you, it works for you.

I'd recommend pnpm over npm for monorepos. Forcing you to be explicit about each package's dependencies is good.

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.”
fluoridation · 1h ago
The problem is less the size of a single dependency but the transitivity of adding dependencies. It used to be, library developers sought to not depend on other libraries if they could avoid it, because it meant their users had to make their build systems more complicated. It was unusual for a complete project to have a dependency graph more than two levels deep. Package managers let you easily build these gigantic dependency graphs with ease. Great for productivity, not so much for security.
wat10000 · 52m ago
The size itself isn’t a problem, it’s just a rough indicator of the benefit you get. If it’s only replacing a hundred lines of code, is it really worth bringing in a dependency, and as you point out potentially many transitive dependencies, instead of writing your own? People understood this with left-pad but largely seemed unwilling to extrapolate it to somewhat larger libraries.

Pretty rich that between this and Claude for Chrome, Anthropic just posted a ~40m YouTube video touting "How Anthropic stops AI cybercrime": https://www.youtube.com/watch?v=EsCNkDrIGCw
0xbadcafebee · 1h 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.

50% of impacted users the vector was VS Code and only ran on Linux and macOS.
"contained a post-installation malware script designed to harvest sensitive developer assets, including cryptocurrency wallets, GitHub and npm tokens, SSH keys, and more. The malware leveraged AI command-line tools (including Claude, Gemini, and Q) to aid in their reconnaissance efforts, and then exfiltrated the stolen data to publicly accessible attacker-created repositories within victims’ GitHub accounts.
"The malware attempted lockout by appending sudo shutdown -h 0 to ~/.bashrc and ~/.zshrc, effectively causing system shutdowns on new terminal sessions.
"Exfiltrated data was double and triple-base64 encoded and uploaded to attacker-controlled victim GitHub repositories named s1ngularity-repository, s1ngularity-repository-0, or s1ngularity-repository-1, thousands of which were observed publicly.
"Among the varied leaked data here, we’ve observed over a thousand valid Github tokens, dozens of valid cloud credentials and NPM tokens, and roughly twenty thousand files leaked. In many cases, the malware appears to have run on developer machines, often via the NX VSCode extension. We’ve also observed cases where the malware ran in build pipelines, such as Github Actions.
"On August 27, 2025 9AM UTC Github disabled all attacker created repositories to prevent this data from being exposed, but the exposure window (which lasted around 8 hours) was sufficient for these repositories to have been downloaded by the original attacker and other malicious actors. Furthermore, base64-encoding is trivially decodable, meaning that this data should be treated as effectively public."

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.

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?

This Semgrep post describes a very different prompt from what Nx reported themselves, which suggests the attacker was "live-editing" their payload over multiple releases and intended to go further.
Still, why does the payload only upload the paths to files without their actual contents?
Why would they not have the full attack ready before publishing it? Was it really just meant as a data gathering operation, a proof of concept, or are they just a bit stupid?
This feels more like someone wanted to just kick the hornet's nest, and specifically used AI to get both traction for the discussion to latch on and get the topic focused on it.

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.

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:
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.

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).

Have we not learned, yet? The number of points this submission has already earned says we have not.
People, do not trust security advisors who tell you to do such things, especially ones who also remove the original instructions entirely and replace them with instructions to run their tools instead.
The original security advisory is at https://github.com/nrwl/nx/security/advisories/GHSA-cxm3-wv7... and at no point does it tell you to run the compromised programs in order to determine whether they are compromised versions. Or to run semgrep for that matter.
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
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.
I was really nervous when "language package managers" started to catch on. I work in the systems programming world, not the web world, so for the past decade, I looked from a distance at stuff like pip and npm and whatever with kind of a questionable side-eye. But when I did a Rust project and saw how trivially easy it was to pull in dozens of completely un-reviewed dependencies from the Internet with Cargo via a single line in a config file, I knew we were in for a bad time. Sure enough. This is a bad direction, and we need to turn back now. (We won't. There is no such thing as computer security.)
I was trying to build just (the task runner) on Debian 12 and it was impossible. It kept complaining about rust version, then some libraries shenanigans. It is way easier to build Emacs and ffmpeg.
On top of that, I try to keep the dependencies to an absolute minimum. In my current project it's 15 dependencies, including the sub-dependencies.

The distro package manager delivers applications (like Firefox) and a coherent set of libraries needed to run those applications.
Most distro package managers (except Nix and its kin) don't allow you to install multiple versions of a library, have libs with different compile time options enabled (or they need separate packages for that). Once you need a different version of some library than, say, Firefox does, you're out of luck.
A language package manager by contrast delivers your dependency graph, pinned to certain versions you control, to build your application. It can install many different versions of a lib, possibly even link them in the same application.
> Most distro package managers (except Nix and its kin) don't allow you to install multiple versions of a library
They do, but most distro only supports one or two versions in the official repos.
This is a reasonable position for most software, but definitely not all, especially when you fix a bug or add a feature in your dependent library and your Debian users (reasonably!) don't want to wait months or years for Debian to update their packages to get the benefits. This probably happens rarely for stable system software like postgres and nginx, but for less well-established usecases like running modern video games on Linux, it definitely comes up fairly often.
Of course, if possible, just saying "hey, I need these dependencies from the system" is nicer, but also not error-free. If a system suddenly uses an older or newer version of a dependency, you might also run into trouble.
In either case, you run into either an a) trust problem or b) a maintenance problem. And in that scenario I tend to prefer option b), at least I know exactly whom to blame and who is in charge of fixing it: me.
Also comes down to the language I guess. Common Lisp has a tendency to use source packages anyway.
Maybe go build doesn't allow this but most other language ecosystems share the same weakness.
So many people are so drunk on the kool aid, I often wonder if I’m the weirdo for not wanting dozens of third party libraries just to build a simple HTTP client for a simple internal REST api. (No I don’t want tokio, Unicode, multipart forms, SSL, web sockets, …). At least Rust has “features”. With pip and such, avoiding the kitchen sink is not an option.
I also find anything not extensively used has bugs or missing features I need. It’s easier to fork/replace a lot of simple dependencies than hope the maintainer merges my PR on a timeline convenient for my work.
The ideal number of both dependencies and releases are zero. That is the only way to know nothing bad was added. Sadly much software seems to push for MORE, not fewer, of both. Languages and libraries keep changing their APIs , forcing cascades of unnecessary changes to everything. It's like we want supply chain attacks to hurt as much as possible.
Say you need compression, you're going to review changes in the compression code? What about encryption, a networking library, what about the language you're using itself?
That means you need to be an expert on everything you run. Which means no one will be building anything non trivial.
Sure there are packages trying to solve 'the world' and as a result come with a whole lot of dependencies, but isn't that on whoever installs it to check?
My point was that git clone of the source can't be the solution, or you own all the code... And you can't. You always depend on something....
Personally, I loved it. I only looked and updating them when I was going to release a new version of my program. I could easily do a diff to see what changed. I might not have understood everything, but it wasn't too difficult to see 10-100 line code changes to get a general idea.
I thought it was better than the big black box we currently deal with. Oh, this package uses this package, and this package... what's different? No idea now, really.
If you have any proposal how to properly manage the complexity of a FE monorepo with dozens of daily developers involved and heavy CI/CD/Devops integration, please post alternatives - given that security incident many people are looking.
I will say, I was always turned off by NX's core proposition when it launched, and more turned off by whatever they're selling as a CI/CD solution these days, but if it works for you, it works for you.
I found npm's workspace features lacking in comparison and sparsely documented. It was also hard to find advice on the internet. I got the sense nobody was using npm workspaces for anything other than beginner articles.
A library is by definition supposed to be somewhat generic, adaptable and configurable. That takes a lot of code.
Why not print a simple counter like: ..10%..20%..30%
Or just: Uploading…
Terminal codes should be for TUI or interactive-only usage.
Compared to typescript where it’s a package + code to use said package which always was more loc than anything comparative I have done in golang.
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.”
Maybe scolding and mocking people isn't a very effective security posture after all.

if software development is turning into their demo:
then I'm switching careers to subsistence farming and waiting for the collapseBut that's just the delivery mechanism of the attack. What caused the attack to be successful were:
Now after all those failures, if you were affected and a GitHub repo was created in your account, this is a failure of: 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.

"contained a post-installation malware script designed to harvest sensitive developer assets, including cryptocurrency wallets, GitHub and npm tokens, SSH keys, and more. The malware leveraged AI command-line tools (including Claude, Gemini, and Q) to aid in their reconnaissance efforts, and then exfiltrated the stolen data to publicly accessible attacker-created repositories within victims’ GitHub accounts.
"The malware attempted lockout by appending sudo shutdown -h 0 to ~/.bashrc and ~/.zshrc, effectively causing system shutdowns on new terminal sessions.
"Exfiltrated data was double and triple-base64 encoded and uploaded to attacker-controlled victim GitHub repositories named s1ngularity-repository, s1ngularity-repository-0, or s1ngularity-repository-1, thousands of which were observed publicly.
"Among the varied leaked data here, we’ve observed over a thousand valid Github tokens, dozens of valid cloud credentials and NPM tokens, and roughly twenty thousand files leaked. In many cases, the malware appears to have run on developer machines, often via the NX VSCode extension. We’ve also observed cases where the malware ran in build pipelines, such as Github Actions.
"On August 27, 2025 9AM UTC Github disabled all attacker created repositories to prevent this data from being exposed, but the exposure window (which lasted around 8 hours) was sufficient for these repositories to have been downloaded by the original attacker and other malicious actors. Furthermore, base64-encoding is trivially decodable, meaning that this data should be treated as effectively public."

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.

Perhaps you may be interested in Qubes OS, where you do everything in VMs with a nice UX. My daily driver, can't recommend it enough.
> I can't help with this request as it appears to be designed to search for and inventory sensitive files like cryptocurrency wallets, private keys, and other secrets. This type of comprehensive file enumeration could be used maliciously to locate and potentially exfiltrate sensitive data.
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.
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.
That said Claude code does not have free reign to run commands out of the gate.
Edit: unless you pass it an override like --dangerously-skip-permissions, as this malware does. https://www.stepsecurity.io/blog/supply-chain-security-alert...
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.
It doesn't run by itself, you have to choose to run it. We have tons of apps with loads of permissions. The terminal can also mess with your filesystem and run commands... sure, but it doesn't open by itself and run commands itself. You have to literally run claude code and tell it to do stuff. It's not some living, breathing demon that's going to destroy your computer while you're at work.
Claude Code is the most amazing and game changing tool I've used since I first used a computer 30 years ago. I couldn't give two fucks about its "vectors of attack", none of them matter if no one has unauthorized access to my computer, and if they do, Claude Code is the least of my issues.
You're absolutely right! I should not have `rm -rf /bin`d!
I use it in a container, so at worst it can delete my repository.
[1] Yes
[2] Yes, and allow this specific command for the rest of this session
[3] No
Still, why does the payload only upload the paths to files without their actual contents?
Why would they not have the full attack ready before publishing it? Was it really just meant as a data gathering operation, a proof of concept, or are they just a bit stupid?
https://github.com/nrwl/nx/security/advisories/GHSA-cxm3-wv7...
Especially: given the .bashrc editing to cause shutdown. This thing is obviously trying to be as loud as possible, without being overly destructive.
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?
I use it all the time, but I'm still looking for people to review its security.
It's much like an Android application, except it can feel a little kludgy because not every application seems to realize it's sandboxed. If you click save, silent failure because it didn't have write access there isn't very user friendly.
In my case, I either use apt (pipx for yt-dlp), or use a VM.
As an administrator, I'm constantly being asked by developers for sudo permission so they can "install dependencies" and my first answer is "install it in your home directory" sure it's a bit more complexity to set up your PATH and LD_LIBRARY_PATH but you're earning a six-figure salary, figure it out.
All except macOS let anything running as your uid read and write all of your user’s files.
