This might just be the frequency illusion at play, but there seem to have been a number of high-profile supply chain attacks of late in major packages. There are several articles on the first few pages of HN right now with different cases.

Looking back ten years to `left-pad`, are there more successful attacks now than ever? I would suspect so, and surely the value of a successful attack has also increased, so are we actually getting better as a broad community at detecting them before package release? It's a complex space, and commercial software houses should do better, but it seems that whilst there are some excellent commercial products (e.g. CI scan tools), generally accessible, idiot friendly tooling is somewhat lacking for projects which start as hobby/amateur code but end up being a dependency in many other projects.

I've cross-posted my comment from the current SAP supply chain attack thread [0].

It's real. As of the beginning of April we'd had 7 in the past 12 months vs 9 in the two decades before that: https://www.jefftk.com/p/more-and-more-extensive-supply-chai...

I think the real question is "are we just hearing about it more now or has the actual rate of attack increased?"

by godelski

5/1/2026 at 5:42:10 PM

I think it is a real increase in the rate of detected attacks, not just awareness, but whether that’s an increase in vigilance or an increase in attacks is hard to know. I suspect both, of nothing else because awareness drives both vigilance and attackers inspired by the earlier attacks.

Personally I was sus of Tailscale, but stopped even pondering it after they got an RCE.

Same with npm and large dependency trees with 10.5 line libraries of low quality.

Lighting always seemed to be the leftpad of PyTorch. It was basically a replacement for a for loop and a couple of backward/step calls. I'm sure now it grew to replace a few more lines of code though. Like maybe a 100.

If you want to look for a coming disaster, look no further than HuggingFace libraries that for some reason quite a lot of projects use these days, especially transformers package. Sadly even vllm depends on it.

> Yeah, and ultimately no body cares.

More like hiding their heads in the sand in circumstances that are outside of their ability to fix. None of the tooling or practices out there push you in the direction of not being at risk, or even provide you with easy ways to stay completely safe: no external packages needed to develop software with everything you NEED being provided out of the box, or a flow where pulling in a new package makes you review all of its source code line by line and compile everything instead of any binary tooling blobs, or built in vulnerability and configuration scanning so you don't get pwned by Trivy or don't leave an open S3 bucket somewhere, which also means that obviously you'd need thorough observability and alerting for any of the cloud stuff you do.

And even when they exist, your org projects might be painfully out of date, too much to use those approaches, or the org culture might not be there, or any number of other issues I can't even imagine. On one hand, people are running out of date software and those have CVEs, on the other using dependencies that are too new also puts you at risks of compromised packages - it's like we're being squeezed by rocks on both sides in a landslide or something. Even at the OS level, the fact that everyone is not running something like Qubes OS or regular VMs for development is absolutely insane. The fact that all software isn't sandboxed and that desktop OSes don't prompt for permissions like mobile apps do is absolutely insane. That we don't have firewalls like Glasswire as standard that prompt you for external connections, or don't allow easily blocking what you don't trust is insane.

Despite lots of people trying their best, on some level, everything both up and down the stack is absolutely fucked for a variety of complex reasons. You'd have to largely tear it all down and rebuild everything starting with your OS kernel in a memory safe language and formal proofs and thorough testing for everything (if it took SQLite as long as it did to get a decent test suite, it might as well take on the order of decades to do it for a production OS kernel and drivers), then do the same for all userland software and DBs and tooling and dependency management and secrets management (not just random files, special hardware most likely) and so on. It's not happening, so we just build towers of cards.

I feel this is an inevitable consequence of a move towards languages with a culture of many small and transitive dependencies.

If my project has 100 dependencies, the release of an updated dependency will inevitably be a daily occurrence.

The value has increased, and that is what drives all these attacks. Cryptocurrencies are to blame in particular because they not just provided a way for money laundering the proceeds but also a juicy target in itself.

And what is stolen with today's malware? Cloud credentials. Either to use for illicit mining, which is on the decline, or to run extortion campaigns, which is made possible by cryptocurrencies. All too often it's North Korea or Iran running these campaigns.

I'm sure the NSA does similar things to them but we aren't really informed about that detail.

by LtWorf

5/1/2026 at 6:22:10 AM

The attacks from TeamPCP were successful at stealing credentials recursively. So it is very likely that someone working on this pytorch related package may have recently pulled the bad litellm or trivy (or what was there like 8 others?)

And the reason it jumps from npm to pip to whatever is that it's trying to find all the user's keys in well known locations for any of these repos.

So teampcp is sitting on tens of thousands of passwords or keys and they just need time to run tests on them to figure out what packages they can release to get even more attacks out there.

Why all the major repo vendors haven't done a full cred wipe? No idea (unless they have and I just wasn't on the email list)

by saltyoldman

5/1/2026 at 12:28:04 PM

The reason is that auto-updates and CI tools have reached a critical saturation and everybody uses them. Years ago, `npm install` would have been more likely to be run manually, and only if something in the build breaks - which means once in a blue moon. Supply chain attacks depend on people (or more likely, pipelines) mindlessly auto-updating packages as soon as they are released.

> Looking back ten years to `left-pad`, are there more successful attacks now than ever?

I can't vouch for the number of attacks, but, and since we are talking about Python, nothing substantially changed since the time of `left-pad`. The same bad things that enabled supply chain attacks in Python ten years ago are in place today. However, it looks like there are more projects and they are more interconnected than before, so, it's likely that there are either more supply chain attacks, or that they are more damaging, or both.

Here's my anecdotal experience with Python's packaging tools. For a while, I was maintaining a package to parse libconfuse configuration language. It started as a Python 2.7 project, but at the time there was already some version of Python 3 available, so, it was written in a way that was supposed to be future-proof.

I didn't need to change the code of the project in the last ten or so years, but roughly once a year something would break in the setup.py. Usually, because PyPA decided to remove a thing that didn't bother anyone.

When Python 3.13 came out, as clockwork, setup.py broke. I rolled up my sleeves and removed the dependency on setuptools, instead, I wrote some Python code that generated a wheel from the project's sources. I didn't look up the specification of the RECORD file in dist-info directory, and assumed that sha256().hexdigest() will generate the checksums in the desired format. And that's how I shipped my packages...

Some time later, the company added an AI reviewer to the company's repo and it discovered that instead of hexdigest() the checksums have to be base64-encoded and then padding removed...

Now, to the punchline: nobody cared. The incorrectly generated packages installed perfectly fine without warnings. Nobody checks the checksums.

More so: nobody checks that during `pip install` or the more fancy `uv pip install` the packages aren't built locally (i.e. nobody cares that package installation will result in arbitrary code execution). It's not just common, it's almost universal to run `pip install` on production machines as a means of deploying a Python program. How do I know this? -- The company I work for ships its Python client as a... source package. Not intentionally. We are just lazy. But nobody cares.

by crabbone

> It's not just common, it's almost universal to run `pip install` on production machines as a means of deploying a Python program.

Maybe a Python culture problem; maybe a hallmark of Python's status as an "easy to hire for", manager-friendly, least common denominator blub language; maybe a risk that stems from the conveniences of interpreter languages... but this is such a shame in this day and age.

It's seriously not difficult to do better. And if this is what you're doing, you're also missing out on reproducible environments both in dev and in prod. At least autogenerate a Nix package! You still don't need to publish any artifacts, but you can at least have the thing build in a sandbox or yeet the whole closure over SSH.

It's also not that hard to get a Docker image out of a Python project.

You only need one platform-minded person on the whole development team to make this happen.

What is going on???

by pxc

5/1/2026 at 5:44:22 AM

"Almost universal" is a bit of a stretch, most of the time these days Python apps are deployed as Docker containers, and if you're using k8s this becomes effectively mandatory.

However a lot of the time especially for older codebases the docker build will just run pip install from public pypi without a proper lockfile.

So at least install code isn't being executed on your production machine, but still significant surface area for supply chain attacks

by ifwinterco

5/1/2026 at 7:52:07 PM

Well, the install code can leave some code behind that will be executed on the production machine... It doesn't really help being in a container. While a separate problem from Python ecosystem, people really put a lot more faith in isolation offered by containers than they should. Also, it's often very tempting to poke holes in that isolation because it's difficult and up to impossible sometimes to get things done otherwise.

by crabbone

4/30/2026 at 9:35:17 PM

It's probably the same people, who think that merely having a requirements.txt stating packages with versions or even without that (2010 sends its regards) is fine. Open a random open source Python project on GitHub, and chances are you will see this kind of thing. Stands to reason, that people in companies are not acting much different.

by zelphirkalt

5/1/2026 at 12:52:00 AM

As scary as it is right now, it warms your heart a little bit that this system existed for 30 years and is only now reaching a crisis point.

I ran an open source project with tens of thousands of downloads (presumably all either developer machines or webservers, so even a small number is valuable) and never received a malicious pull request, offer of a bribe to install malware, or a phishing attempt with enough effort to even catch my attention.

What it says to me is that there weren't a lot of people working on the crime side of this. It's like dropping your wallet in a bar bathroom and coming back to find it still there.

You can call it laziness, but it's not like the python ecosystem has ever developed an answer for this problem. The only reasonable answer has been to use docker, which is basically admitting that the python community did nothing.

by imtringued

5/1/2026 at 8:06:12 PM

Oh, that's a sore spot with me, but I'm glad you asked!

So, for the purpose of full disclosure, I have a personal and professional grudge with PyPA, which also touches on how pip is being managed, beside other packaging issues. It's not the side you want to be on, so, be warned!

So, without further ado: I write my own code to generate the deployed artifact. In my case, I take all the wheels installed in my environment, extract them, and merge them into a single wheel. The process also usually involves removing a bunch of junk from the packages packaged in such a way. You'd be surprised how much nonsense people put in their distributed packages... like, their unit tests, or documentation in HTML / PDF format, __pycache__ files (together with the sources)... the list goes on.

But, it works because I curate what's being installed. I don't trust pip to install just or everything I need. I run it in a separate environment, where I examine the packages that have been installed as dependencies, figure out why any of these packages were installed (you'd be surprised how often you don't need them!), then, I make a list of the dependencies I actually need, with the exact versions and checksums, and use a Python or a Shell script to download and install them in the actual development environment.

This isn't a good idea when you have many short-lived projects, but, in my case, the typical project lifespan is measured in decades and there aren't that many of them. So, I can expend the extra effort required to do that.

Unfortunately, I don't think there's a way to automate the process. The key point is that there's a human who sifts through dependencies and figures out what to do with them. Partially automate, maybe... but I can't think of a way to make this into a program that I could give someone.

by crabbone

5/1/2026 at 5:32:18 PM

> virtualenv isn't relocatable out of the box, so how else would you deploy a python project?

My team has a handful of Python projects. Here's how they work:

devenv.nix provides a Python runtime and all native dependencies, git hooks for linters and things like this. It integrates with direnv and the Python package manager (currently Poetry 1.x for older projects and uv for newer ones) so that when you cd in you get a virtualenv with everything you need, scripts in the project (or stubs for them) magically appear on your PATH so you don't need to use `uv run` or whatever it is for anything.

flake.nix provides a publishable artifact for projects that we run on workstations or servers. It autogenerates a Nix package from pyproject.toml and friends. You can reproducibly build it across platforms without virtualization, you can push it up to a binary cache and avoid source builds, whatever. It's great.

For projects that we run in cloud-native containers (for us AWS Fargate and AWS Lambda), we don't currently ship our own container images. We just publish zip files that we generate with a Poetry plugin that runs builds inside containers that have the same images as are used by AWS in its default runtime environments and push them up with the AWS CLI. The exact steps are stored as a Devenv script so the CI can be a one liner and you can run everything locally just like you would in CI.

> the python community did nothing

Python sucks.

But you can still represent your Python project as a proper Python package and get reproducible-ish build artifacts that are local-first and embrace Python-native tooling and ship it up to prod in a portable format with or without Docker. It only takes one engineer spending a day or two to work it out once for the whole team or maybe the whole company. You just need someone to be willing to RTFM on a package manager or two. The Python community seems to be largely lacking such people but your team doesn't have to be.

by michaelt

FWIW left-pad was not an attack, it was a bug in NPM. It should not be possible to unpublish package versions that are depended on by other published packages. On the other hand, it should be possible to unpublish certain package versions that are new and not depended on.

NPM should have returned error codes when the author of left-pad attempted to remove all his data with the intention of leaving the service.

To quote Wikipedia:

> After Koçulu expressed his disappointment with npm, Inc.'s decision and stated that he no longer wished to be part of the platform, Schlueter [author of NPM] provided him with a command that would delete all 273 modules that he had registered.

No need to invoke frequency illusion when every moderate HN lurker already stopped counting. https://socket.dev/blog gives a good impression, but a dedicated article would be nice. Maybe recurring once or twice a year.

If you're interested in synchronicity and frequency illusion, Sergei v. Chekanov wrote a book that sounds interesting https://jwork.org/designed-world/

Have you ever experienced coincidences that cannot be logically explained? This book helps the readers understand the meaning of synchronicity, or remarkable coincidences in people's lives. This work not only explains the mystery of synchronicity, originally introduced by Carl Jung, but it also shows how to make simple calculations to estimate the chances that coincidences are not due to mere randomness.

I cant wait to have no dependencies.

An extreme example is now when I make interactive educational apps for my daughter, I just make Opus use plain js and html; from double pendulums to fluid simulations, works one shot. Before I had hundreds of dependencies.

Luckily with MIT licensed code I can just tell Opus to extract exactly the pieces I need and embed them, and tweaked for my usecase. So far works great for hobby projects, but hopefully in the future productions software will have no dependencies.

The problem with this is now you are solely responsible for managing all of the changes, all of the variation of life. Chrome changed the shape of this API, you are responsible for finding it and updating it. Morocco changed when their daylight savings took effect, now you need to update your date/time handling code. There are a lot of these things that we take for granted because our libraries handle it for us, and with no dependencies you have to do all the work. Not a big deal for making a double-pendulum simulator for your daughter to play with that will stop mattering next week, but is a concern for a company which is trying to build something that can run indefinitely into the future.

by mandevil

vs the dependency broke something and now you're responsible for working around someone else's broken code.

Honestly, I've seen much more of the latter. Especially nowadays with every single dependency thinking they are an fully fledged OS because an agent can add 1000 feature/bug in no time. Picking the right dependency maintaining by a sane maintainer is like digging potatoes in a minefield.

by Aperocky

4/30/2026 at 7:09:37 PM

As a general principle, I agree with you that large companies and teams benefit from common runtimes (i.e. libraries and frameworks).

I don't buy the notion of things breaking down over time, though. For "first-party" code that sticks to HTML and CSS standards, and Stage 4 / finished ecmascript standards, the web is an absurdly stable platform.

It certainly used to be that we had to do all sorts of weird vendor hacks because nobody agreed on anything and supporting IE6 and 7 were nightmares, and blackberry's browser was awful, but those days are largely behind us unless you're doing some cutting-edge chrome-only early days proposed stuff or a browser specific extension or something else that isn't a polished standard.

Even with timezone changes, you're better off using the system's information with Intl.DateTimeFormat.

In the Python ecosystem making software with reproducibility in mind was a thing before the advent of uv. Some earlier options include Pipenv and Poetry. I used Pipenv already some 6y ago to achieve that and later switched to Poetry.

I think devs who didn't care back then also won't care in the future and will still run around with requirements.txt file in 10 years.

by zelphirkalt

4/30/2026 at 7:19:40 PM

In companies, though, you often wind up with three+ massive dependency trees in your software to handle the same problem because people went and added the new hotness without deprecating the old stuff. You also find dependencies that are much heavier than necessary for the actual task at hand because the software developer was also solving the problem of needing that dependency on their resume. And then there's just the relatively tiny dependencies for fairly solved problems, like leftpad, which don't really require deps, and you can accept the maintenance burden, because not everything is an abstraction layer over chrome.

So if you just need to do something simple like fire off a compute heavy background task and then get a result when it is done, you should probably just roll your own implementation on top of the threading API in your language. That'll probably be very stable. You don't need a massive background task orchestration framework.

People might object that the frameworks will handle edge cases that you've never thought of, but I've actually found in enterprise settings that the small custom implementations--if you actually keep it small and focused--can cover more of the edge cases. And the big frameworks often engineer their own brittle edge cases due to concerns that you just don't have.

So anyway, it isn't as simple as "dependencies are bad" or "dependencies are good", but every dependency has a cost/benefit analysis that needs to go along with it. And in an Enterprise, I'd argue that if you audit the existing dependencies you will find way too many of them that should be removed or consolidated because they were done for the speed of initial delivery and greenfielding. Eventually when you accumulate way too many of those dependencies the exposure to the supply chains, the need to keep them updated, the need to track CVEs in those deps, and the need to fix code to use updated versions of those dependencies, along with not have the direct ability to bugfix them, all combine to produce an ongoing tax of either continual maintenance or tech debt that will eventually bite you hard.

We seem to greatly overestimate the amount of code needed to do something.

For example, there are billions of lines of code from me pressing a key, to you seeing what I wrote. But if we were to make a special program that communicates via ipv6 and icmp, and it is written for hazard3 pico2350 with wiz5500 ethernet breakout, the whole thing including the c compiler to compile your code (which could very well outperform gcc -O3) will be 5-6k lines of code, including RA, and even barebones spi drivers, and a small preemptive os.

So, it is not unreasonable to manage all of those changes.

by jackdoe

5/1/2026 at 1:38:22 AM

I think we are stuck with LLMs. They are already in a place where they can find these issues in the first place. They can access RSS feeds. You could cron an agent to look to see if you are pwned as frequently as you want at literally almost zero cost. When you do ingest the libraries, keep a list and of what version and that can help as well.

by solid_fuel

5/1/2026 at 5:33:09 PM

Yes, I trust my LLM codegen and review process far more than the code I was never going to read from all of my transitive deps and every sequential update to them forever.

This is a trivial bargain for most libraries we were using not long ago out of convenience. Like a library just for setting ansi colors for your TUI.

Ideally you have minimal deps scoped to the truly hard things: libghostty, btrfs, luks, postgres, etc. Then you focus on the application and generate the mechanical glue code on demand with a solid harness that keeps the important stuff well-tested.

Though you’ll need to figure out how to build that harness/process before it really delivers.

I sort of agree with you but for me, I prefer golang because I believe that for most use cases, Golang fits perfectly (I run a 500mb 7$/yr vps with debian and use golang binaries)

Cross portability and compilation and its very few dependency/stdlib approach with simplicity, I just really love golang.

I had built[0] a cuckoo.org alternative at https://fossbox.cloud which has only one dependency of gorilla web sockets aside from stdlib

If I were to rewrite it in rust, I couldn't say the same. Golang's stdlib is that good.

My point is, although I understand Rust can have some advantages in other areas, the advantages of golang outweigh rust for me by a very high margin. There is also the factor that I just feel more comfortable reading golang code and picking through it than rust.

It is my opinion that you can go a very very long way with a garbage collector than people imagine even on constrained systems. Unless absolutely necessary, thinking about GC feels like it might be a premature optimization in many instances which is worth thinking about.

[0]: More like (vibecoded?) as this is just a single file main.go which I had prompted on gemini 3.1 pro sometime ago. It was just a prototype which works surprisingly well that I had made because I was using the cuckoo website with friends but it kept on lagging.

Well I almost have the same story, my agent harness is a 5mb rust binary that runs as systemd service and occupy 10mb of memory after days. This handles all communciations between 100+ agents.

Now I think go will come close to this number, so in reality, there might not be a real difference. But a leak somewhere is far more likely especially as these are mostly vibe coded (my binary has multiple functionality).

The biggest advantage that go have over rust is the stdlib and ecosystem that doesn't depend on 100 packages. And maybe that will be the deciding factor in the future or someone (I'm getting increasingly itchy for it) will need to reinvent the ecosystem to be less like npm.

You can encode so much design and intent in the Rust type system. It’s one of the best things about Rust.

I prefer to write Go if I were doing everything by hand. But now everything is Rust. And a quick scroll through my Rust types, the discriminated union types, the discriminated error types, the high level application types, it’s just so much better for spec’ing out a system and leaving no question about what some bit of code is trying to do and the states it’s trying to prohibit.

And with an LLM, the hard things about Rust that would’ve had me asking questions on IRC are not hurdles anymore.

Granted, it has its own cultural NPM/RubyGem dep spam problem when you watch cargo install’s output.

I think in the relatively near future we’re going to start seeing sophisticated supply chain attacks into language model training data.

It should be feasible to design vulnerabilities which look benign individually in training data, but when composed together in the agent plane & executed in a chain introduce an exploit.

There’s nothing technical really stopping that from existing right now. It’s just that nobody has put the effort in yet.

by OtherShrezzing

4/30/2026 at 8:19:17 PM

The develop-test-refine feedback loop for this kind of attack is so long (or expensive) that it seems likely to limit its real world use. Poison training data, wait months? a year? for the model to come out, see how well it worked, refine... or do you see a faster way to iterate?

by lacunary

5/1/2026 at 9:31:26 AM

Continual learning is the next major architectural milestone for the frontier labs. That’d reduce the iteration loop to days instead of years.

If your attacker assumes that all or most software will be generated from language models, the time penalty is worth paying.

No, I'd posit the average developer who pulls in hundreds of deps but now uses LLMs to effectively replace them can not build things equally well without either.

That doesn't really explain why there is a bunch of GitHub repos created as well.

If I remember correctly from Shai-Hulud 2, the attacker extricated creds by posting them in public github repos with minor easily reversible encryption. I believe it was double b64 last time.

I'm assuming the logic there is that every security researcher and company is going to pull and scan those creds for their stuff and their clients' stuff. So the attacker is just 1 of N people downloading it. As opposed to trying to send it to their own machine directly.

by CodeAndCuffs

4/30/2026 at 6:04:30 PM

I think it's more about convenience and bypassing filters - developers are already logged in to github, already have access to create repos and publish code, firewalls will allow it. Even fancy HIDS systems will think the git push is rather normal.

If they have a clue, the attacker still will not download that without using a botnet tunnel or Tor at a minimum.

Note though that these credentials aren't even encrypted using some lightweight ECC to prevent others from capturing them, they're posted in cleartext. Embarassment might be part of the point.

by arsome

5/1/2026 at 4:37:01 AM

With HN ettiquette in mind, I must make an exception: this is a case where skimming the first parts of the article would help a lot!

The public repo path is just one of four parallel paths, with the goal of getting around any barriers:

  The exfiltration component shares its design with the "Mini Shai-Hulud" mechanism from their last campaign, using four parallel channels so stolen data gets out even if individual paths are blocked.

When I was doing Fast.AI Deep Learning course, I was surprised by the number of Python dependencies machine learning projects bring. Web front-end projects were always considered very third-party dependencies heavy, but to me, the machine learning ecosystem looks much more entangled. In addition, unlike web development, which is considered security critical and has over the many years accumulated a lot of wisdom and good security-related practices, machine learning development looks much more ad-hoc, with many common software engineering practices not applied.

For example, at that time, one way to distribute machine learning models was via Python pickles. Which are executable objects with no restriction built in. Models in this format could do anything on a computer where the model was imported. Such an early 'wild-west' ecosystem can definitely make security compromises easier and resulting supply chain attacks more common.

by mixedbit

4/30/2026 at 10:19:42 PM

There are many people in that ecosystem, who are not primarily software engineers. Some just learned some coding along the way. Some are mathematicians. Some are devs who are AI drunk or something. Some have the mindset of "code doesn't matter any longer, if it works it works". For many proper dependency management is just a chore, that they don't want to care about. These things come together in various ML projects, even though ML projects should be amongst the projects most focused on reproducibility.

This week I was wondering whether using uv for managing Python versions is a good idea.

From their website [1]

> Python does not publish official distributable binaries. As such, uv uses distributions from the Astral python-build-standalone project. See the Python distributions documentation for more details.

It points to this GitHub repo https://github.com/astral-sh/python-build-standalone which mentions this other link https://gregoryszorc.com/docs/python-build-standalone/main/r...

If I understand correctly, the source code for building Python is not fetched directly from python.org. Not so sure how secure is that.

I have the same concern for asdf [2]. However, they use pyenv [3] which, I think, feels more official.

Can someone clarify this? Which tool is better/more secure for installing python: uv or asdf?

[1] https://docs.astral.sh/uv/guides/install-python/

I'm really not worried about `uv` and `cpython` -- their processes are robust, their response times fast, and (now) their funding significant

I'm worried about, say, `mdformat` (a widely used formatter mostly maintained by one person in their spare time), not to mention some super-specific dependency that hasn't been updated in years and is 3 levels deep in your dep tree. I really don't want to pin & manually approve every single update for an app that's under active development, but it's beginning to look like that's mandatory for any serious app.

In the meantime, I've gotta go get my API keys out of my unencrypted `.env` files! Getting burned on a large, consumer-facing webapp would be embarrasing but logical, but losing hundreds to thousands of dollars because of some indirect dependency of some silly one-off demo repo that just happens to be on the same host & system as my `.env`s... oof.

Anyone know if OAI or Anthropic will refund you if you get your keys stolen like this? Or is it user error?

by bbor

4/30/2026 at 7:38:50 PM

Indeed, I also use LLMs to suggest dependencies but:

- I ask the LLM for multiple options

- I tell it what I need and what I don't need

- I then look at the packages it has suggested. Sometimes LLMs suggest unmaintained packages with 5 downloads a month just because it came at the top of a web search.

- if it's not a very well known project, I look at the code, I have received vibecoded dependency suggestions before that don't even function

LLMs are useful resources for "getting the pulse of the ecosystem", but just pressing enter is crazy.

Stale training data is part of it. But even a current model can't tell what setup.py is going to run on your box. Nothing actually inspects the package before it executes. You'd want something that pulls the metadata and checks what hooks are in there before anything runs.

Built Packj [1] to do exactly this.

1. Packj (https://github.com/ossillate-inc/packj) detects malicious PyPI/NPM/Ruby/PHP/etc. dependencies using behavioral analysis. It uses static+dynamic code analysis to scan for indicators of compromise (e.g., spawning of shell, use of SSH keys, network communication, use of decode+eval, etc). It also checks for several metadata attributes to detect bad actors (e.g., typo squatting).

by CoastalCoder

5/1/2026 at 8:17:38 PM

You can use devcontainers (in VSCode or separate), like this: https://github.com/entn-at/claude-rust-devcontainer/

This will limit the agent in what it can do in the system and what IPs/domains it can reach. This requires a lot of customization to your specific framework/environment. Note that this can reduce the agent’s effectiveness, as it will have to “work around” some of the limitations. This isn’t foolproof either, and the agent could exfiltrate data e.g. via DNS requests.

Disclaimer: I've never used pytorch and I also know nothing about software security practices.

But I don't see a scenario where pytorch needs network access. It seems wrong that at any level within the codebase I can import any module and use its API.

I think there need to be additional import restrictions or static analysis.

This also seems like languages do not have the right abstractions to talk about this stuff. As a comparison, I like how in rust I can look at the function signature and see the mutability and lifetimes of everything without understanding any of the code underneath.

I feel there needs to be something similar here with dependencies. A dev should be able to audit all their dependencies easily and see "oh dep X uses eval()" or network access, etc without looking at any underlying code.

Mobile apps enforce permissions. Shouldn't a dev be able to whitelist certain functionality and not take everything including the kitchen sink.

by kalinkochnev

5/1/2026 at 2:28:09 PM

The python ecosystem will never permit this, but I sure wish this topic was better understood and appreciated within it. I hate to generalize, but the AI dev community in particular seems to favor convenience over every other consideration.

For example, the norm for projects is to happily automatically download large models upon first use. Often you can disable this, but the deep layering of code classes throughout various libraries makes discovering the right parameters a PITA.

It is great that you can bootstrap complex things (toys, more often than not) so painlessly, but I find the permissiveness quite jarring. The first troubleshooting step always seems to be “pip install …” and some environments (e.g. MacOS) don't virtualize GPU access well.

It's always crypto. A client got some AWS credentials stolen and without anyone checking the account, the hacker managed to spin up big EC2 instances across many regions. The bill after a month as I recall was around 100K. Since the activity was clearly fraudulent the bill was forgiven eventually. So remember to lock down your AWS keys permissions...

That; and also, enable the various monitoring and audit features in AWS now; start with CloudTrail. Nothing worse than being affected by this attack, and AWS not having any audit trail available.

The decision to run all of my experiments in a monorepo with a single uv.lock continues to be validated. I usually only update it a few times a year. It was pinned at 2.6.1 for lightning \o/

When I was a kid, we've been told to be cautious with third party dependencies, that code can do anything and it's a risk to evaluate.

With the new generation of yolo NPM scripters, they simply don't evaluate the risks. They will even fight back telling you that it's the way of doing things.

In reality, it's the warning we learnt back then, that's the result of be mindlessly importing third dependencies without thinking.

In other words, the risks were always there, the new "modern way", let's put it that way, doesn't put the effort anymore.

That, and it is combined with not being willing to write a few functions oneself, which one could easily do, and then not have to add a dependency. But it is also a result of trying to do everything quickly quickly! and being pushed to do that.

The more one knows about computer programming, algorithms, data structures, how things are usually implemented in general, the better one can avoid unnecessary dependencies. Needs the right environment though to execute on that.

tbf, most tech-related corporate environments don't want you to think, just do (kpi, mbo, okr et al) and this is one of the results

Let's be real tho, there's a whole lot of people who have been around enough to know better that do this too.

so i'm guessing something like this would be caught by (open\|little)snitch. the raw c2 post coming from the python process would definitely be a red herring, but i wonder how obvious the git/github activity would be. it would seem kinda weird if it came from the python process itself, but if it were just git or gh in a subprocess, it would possibly look totally normal and even have a temporary allow rule in place...

maybe it's time for a nextgen opensnitch where the rules table is replaced by an active agent that watches connections and the process table?

How can we prevent this? Can we not start forcing MFA for git pushes? Use your fingerprint, MFA, or yubikey - reject unsigned commits on public repos?

I find this constant churn in the software world to be tiresome. I get it if there is a security update. Or you are building something new; it takes time and a series of updates to reach feature parity on 1.0. But most software is not like that. All these online registries make the problem worse. Any random tool installation pulls in 300 different dependencies.

This is why I have been building, for my own usecases, a new language + compiler + vm that is completely source based. The compiler does not understand linking. You must vendor every single dependency you use, including the standard library, so that it makes its way into the bytecode. The register VM itself is a few thousand lines of freestanding C. Any competent programmer can audit it over a weekend.

v1 deliberately keeps FFI (outside of a bounded set of linux syscalls) outside the current spec as libc has the habit of infecting everything it touches and I want to keep Vm0 freestanding. The last time I compiled the VM, it produced a 70KB binary and supported a loader with structural verification, the entire instruction set using a threaded interpreter, a simple Cheney+MS GC, concurrency via an Erlang-style M:N scheduler working on a single thread, and 20-odd marshaled functions.

Most software in the world does not need anything more than this. Everyone acts as if they are building the next Google.

Shai-Hulud strikes again and continues to turn innocent packages into zombies.

Think twice before looking at a package and most importantly, always pin your dependencies.

by rvz

4/30/2026 at 6:04:40 PM

Yeah, pin the malware :p

by pixel_popping

4/30/2026 at 7:21:05 PM

Nope. Those on pinned versions don't get the malware.

You would have to publish the infected package first to infect others who haven't pinned their dependencies. With a simple pip install -U, and if the dependency is not pinned, then they will get the vulnerable version.

by rvz

5/1/2026 at 9:46:23 AM

I think it was a jab at the statement "if I pin the dep, I am safe". How do you know your current code is not compromised? No one reads all the code they run, anyway.

by ramon156

5/1/2026 at 1:17:47 PM

There is always a risk that at the time that you pinned, the code was already compromised, but it lowers your attack surface to pin. As long as you've pinned while the code was not compromised, then someone changing the package for an already pinned version will fail the install because hash check fails.

It's "if I pin the dep, I know that someone won't compromise the package repo and the next time I install 2.6.3 I can be sure that the same package is getting downloaded and installed."

This specific risk isn't just not having things version pinned. It's not having a hash of the package to check against to make sure you're getting the same package every time.

Am I the only one who thought that by using github links for an dependency source is not a wise thing to do?

Do folk not understand that by doing so, you're enabling modules to maliciously write themselves in to your code?
