If your first party tooling contains all the functionality you typically need, it's possible you can be productive with zero 3rd party dependencies. In practice you will tend to have a few, but you won't be vendoring out critical things like HTTP, TCP, JSON, string sanitation, cryptography. These are beacons for attackers. Everything depends on this stuff so the motivation for attacking these common surfaces is high.

I can literally count on one hand the number of 3rd party dependencies I've used in the last year. Dapper is the only regular thing I can come up with. Sometimes ScottPlot. Both of my SQL providers (MSSQL and SQLite) are first party as well. This is a major reason why they're the only sql providers I use.

Maybe I am just so traumatized from compliance and auditing in regulated software business, but this feels like a happier way to build software too. My tools tend to stay right where I left them the previous day. I don't have to worry about my hammer or screw drivers stealing all my bitcoin in the middle of the night.

Also from the report:

> Neither malicious version contains a single line of malicious code inside axios itself. Instead, both inject a fake dependency, plain-crypto-js@4.2.1, a package that is never imported anywhere in the axios source, whose only purpose is to run a postinstall script that deploys a cross-platform remote access trojan (RAT)

Good news for pnpm/bun users who have to manually approve postinstall scripts.

I also have `ignore-scripts=true` in my ~/.npmrc. Based on the analysis, that alone would have mitigated the vulnerability. bun and pnpm do not execute lifecycle scripts by default.

Here's how to set global configs to set min release age to 7 days:

  ~/.config/uv/uv.toml
  exclude-newer = "7 days"

  ~/.npmrc
  min-release-age=7 # days
  ignore-scripts=true
  
  ~/Library/Preferences/pnpm/rc
  minimum-release-age=10080 # minutes
  
  ~/.bunfig.toml
  [install]
  minimumReleaseAge = 604800 # seconds

If you're developing with LLM agents, you should also update your AGENTS.md/CLAUDE.md file with some guidance on how to handle failures stemming from this config as they will cause the agent to unproductively spin its wheels.

find . -name "package.json" -exec sh -c ' dir=$(dirname "{}") echo "==== $dir ====" cd "$dir" npm list axios 2>/dev/null | grep -E "1\.14\.1|0\.30\.4" grep -A1 "\"axios\"" package-lock.json 2>/dev/null | grep -E "1\.14\.1|0\.30\.4" [ -d node_modules/plain-crypto-js ] && echo "POTENTIALLY AFFECTED" ' \;

The solution to this is twofold, and is already implemented in the primary ecosystems being targeted (Python and JS): packagers should use Trusted Publishing to eliminate the need for long lived release credentials, and downstreams should use cooldowns to give security researchers time to identify and quarantine attacks.

(Security is a moving target, and neither of these techniques is going to work indefinitely without new techniques added to the mix. But they would be effective against the current problems we’re seeing.)

Unfortunately npm is friggen awful at this...

You can use --ignore-scripts=true to disable all scripts, but inevitably, some packages will absolutely need to run scripts. There's no way to allowlist specific scripts to run, while blocking all others.

There are third-party npm packages that you can install, like @lavamoat/allow-scripts, but to use these you need to use an entirely different command like `npm setup` instead of the `npm install` everyone is familiar with.

This is just awful in so many ways, and it'd be so easy for npm to fix.

I have bwrap configured to override: npm, pip, cargo, mvn, gradle, everything you can think of and I only give it the access it needs, strip anything that is useless to it anyway, deny dbus, sockets, everything. SSH is forwarded via socket (ssh-add).

This limits the blast radius to your CWD and package manager caches and often won't even work since the malware usually expects some things to be available which are not in a permissionless sandbox.

You can think of it as running a docker container, but without the requirement of having to have an image. It is the same thing flatpak is based on.

As for server deployments, container hardening is your friend. Most supply chain attacks target build scripts so as long as you treat your CI/CD as an untrusted environment you should be good - there's quite a few resources on this so won't go into detail.

Bonus points: use the same sandbox for AI.

Stay safe out there.

It’s things like this that make me want to swap to Qubes permanently, simply as to not have my password manager in the same context as compiling software ever.

I just wish it had more human interaction rather than have a GenAI spit out the blog post. It's very repetitive and includes several EM dashes.

— Run Yarn in zero-installs mode (or equivalent for your package manager). Every new or changed dependency gets checked in.

— Disable post-install scripts. If you don’t, at least make sure your package manager prompts for scripts during install, in which case you stop and look at what it’s going to run.

— If third-party code runs in development, including post-install scripts, try your best to make sure it happens in a VM/container.

— Vet every package you add. Popularity is a plus, recent commit time is a minus: if you have this but not that, keep your eyes peeled. Skim through the code on NPM (they will probably never stop labelling it as “beta”), commit history and changelog.

— Vet its dependency tree. Dependencies is a vector for attack on you and your users, and any new developer in the tree is another person you’re trusting to not be malicious and to take all of the above measures, too.

There are pretty much exactly 3000 deleted issues, with the range starting at https://github.com/axios/axios/issues/7547 (7547) and ending at https://github.com/axios/axios/issues/10546 (10546 which is 7547+2999)

Maybe just a coincidence but they have cubic-dev-ai edit every single PR with a summary. And that bot edits PR descriptions even for outside contributors.

You should probably set your default to not run those scripts. They are mostly unnecessary.

  ~/.npmrc :
  ignore-scripts=true

We have libraries like SQLite, which is a single .c file that you drag into your project and it immediately does a ton of incredibly useful, non-trivial work for you, while barely increasing your executable's size.

The issue is not dependencies themselves, it's transitive ones. Nobody installs left-pad or is-even-number directly, and "libraries" like these are the vast majority of the attack surface. If you get rid of transitive dependencies, you get rid of the need of a package manager, as installing a package becomes unzipping a few files into a vendor/ folder.

There's so many C libraries like this. Off the top of my head, SQLite, FreeType, OpenSSL, libcurl, libpng/jpeg, stb everything, zlib, lua, SDL, GLFW... I do game development so I'm most familiar with the ones commonly used in game engines, but I'm sure other fields have similarly high quality C libraries.

They also bindings for every language under the sun. Rust libraries are very rarely used outside of Rust, and C#/Java/JS/Python libraries are never used outside their respective language (aside form Java ones in other JVM langs).

This needs to be done (as we've seen from these recent attacks) in your devenv, ci/cd and prod environments. Not one, or two, but all of these environments.

The easiest way is via using something like kubernetes network policies + a squid proxy to allow limited trusted domains through, and those domains must not be publicly controllable by attackers. ie. github.com is not safe to allow, but raw.githubusercontent.com would be as it doesn't allow data to be submitted to it.

Network firewalls that perform SSL interception and restrict DNS queries are an option also, though more complicated or expensive than the above.

This stops both DNS exfil and HTTP exfil. For your devenv, software like Little Snitch may protect your from these (I'm not 100% on DNS exfil here though). Otherwise run your devenv (ie vscode) as a web server, or containerised + vnc, a VM, etc, with the same restrictions.

Dealing with dependencies is another question; if it's stupid stuff like leftpad then it should be either vendored in or promoted to be a language feature anyway (as it has been).

I've been working on Proof of Resilience, a set of 4 metrics for OSS, and using that as a scoring oracle for what to fund.

Popularity metrics like downloads, stars, etc are easy to fake today with ai agents. An interesting property is that gaming these metrics produces better code, not worse.

These are the 4 metrics:

1. Build determinism - does the published artifact match a reproducible build from source?

2. Fuzzing survival - does the package survive fuzz testing?

3. Downstream stability - does it break any repos dependent on this project when pushing a release?

4. Patch velocity - how fast are fixes merged?

Here's a link to the post, still early but would appreciate any feedback.

All it takes is an `npm config set` to switch registries anyways. The hard part is having a central party that is able to convince all the various security companies to collaborate rather than having dozens of different registries each from each company.

Rather than just a hard-coded delay, I think having policies on what checks must pass first makes sense with overrides for when CVEs show up.

(WIP)

Wouldn’t that just encourage the bad actors to delay the activation of their payloads a few days or even remotely activated on a switch?

I wrongly thought that the verified provenance UI showed a package has a trusted publishing pipeline, but seems it’s orthogonal.

NPM really needs to move away from these secrets that can be stolen.

What a great time to be alive! Now, that's exactly why I enjoy writing software with minimal dependencies for myself (and sometimes for my family and friends) in my spare time - first, it's fun, and second, turns out it's more secure.

I'm not dogmatic about the whole "JS for the backend is sin" from backend folks, but it seems like it was the right call. You should stick to large org backed packages, or languages with good enough standard libraries, like Go, Java, Python, C#.

The anti-forensics here are much more complicated that I had imagined. Sahring after getting my hands burned.

After the RAT deploys, setup.js deletes itself and swaps package.json with a clean stub. Your node_modules looks fine. Only way to know is checking for artifacts: /Library/Caches/com.apple.act.mond on mac, %PROGRAMDATA%\wt.exe on windows, /tmp/ld.py on linux. Or grep network logs for sfrclak.com.

Somehow noboady is worried about how agentic coding tools run npm install autonomously. No human in the loop to notice a weird new transitive dep. That attack surface is just getting worsened day by day.

That way, I can at least limit the blast radius when (not if) I catch an infostealer.

   find / -path '*/node_modules/axios/package.json' -type f 2>/dev/null | while read -l f; set -l v (grep -oP '"version"\s*:\s\*"\K(1\.14\.1|0\.30\.4)' $f 2>/dev/null); if test -n "$v"; printf '\a\n\033[1;31m FOUND v%s\033[0m  \033[1;33m%s\033[0m\n' $v (string replace '/package.json' '' -- $f); else; printf '\r\033[2m scanning: %s\033[K\033[0m' (string sub -l 70 -- $f); end; end; printf '\r\033[K\n\033[1;32m scan complete\033[0m\n'

Zero deps. One file. Already detects the hijacked maintainer email on the current safe version.

This is why corporations doing it right don't allow installing the Internet into dev machines.

Yet everyone gets to throw their joke about PC virus, while having learnt nothing from it.

https://github.com/axios/axios/issues/10604

Project: https://point-wild.github.io/who-touched-my-packages/

Website: https://asfaload.com/

GitHub:https://github.com/asfaload/asfaload

Spec: https://github.com/asfaload/spec

Now, I tend to use Python, Rust and Julia. With Python I am constantly using few same packages like numpy and matplotlib. With Rust and Julia, I try as much as possible to not use any packages at all, because it always scares me when something that should be pretty simple downloads half of the Internet to my PC.

Julia is even worse than Rust in that regard - for even rudimentary stuff like static arrays or properly namespaced enums people download 3rd party packages.

Edit: bottom line is installs are gonna get SOOO much more complicated. You can already see the solution surface... Cooling periods, maintainer profiling, sandbox detonation, lockfile diffing, weird publish path checks. All adds up to one giant PITA for fast easy dev.

Doesn’t npm mandate 2FA as of some time last year? How was that bypassed?

Another obvious ChatGPT-ism. The fact that people are using AI to write these security posts doesn't surprise me, but the fact they use it to write a verbose article with spicy little snippets that LLMs seem to prefer does make it really hard to appreciate anything other than the simple facts in the article.

Yet another case in point for "do your own writing" (https://news.ycombinator.com/item?id=47573519)

Storing your sensitive data on a single bare-metal OS that constantly downloads and runs packages from unknown maintainers is like handing your house key out to a million people and hoping none of them misuse it.

So this and litellm one would’ve been preventable by proper config of OIDC Trusted Publishers.

It's a bit janky right now but I'd be interested to hear what people think about it.

Have a branch called testing, and packages stay in testing for few weeks, after which they go to stable. That is how many Linux distributions handle packages. It would have prevented many of these.

Advising every user of npm/pnpm to change their settings and set their own cooldown periods is not a real choice.

This might have taken a lot longer to discover, otherwise.

JavaScript, its entire ecosystem is just a pack of cards, I swear. What a fucking joke.

“I’m smart I use fetch instead of axios”. “I pin my versions” – sure but certainly one of your npx or Electron apps uses axios or another less notably compromised package.

Let’s

It won't stop all attacks but definitely would stop some of these

Looks like the maintainer wasn't just careless when reviewing PRs.

WTF!!!! gaslighting your victims into believing they are not victims. the ingenuity of this is truly mindblowing. I am shocked at such thing is even allowed. like packages should not be able to modify their contents while they are being instaleld.

Learn about 'guix import'.

Oh, and you can install Guix on any GNU/Linux distro.

Sure, its convenient to have so much code to use for basic functionality - but the technical debt of having to maintain these projects is just too damn high.

At this point I think that, if I am forced to use javascript or node for a project, I reconsider involvement in that project. Its ecosystem is just so bonkers I can't justify the effort much longer.

There has to be some kind of "code-review-as-a-service" that can be turned on here to catch these things. Its just so unproductive, every single time.

Stop downloading code from the internet unless it's a major strategic decision.

I think that jason might like if someone from github team can contact them as soon as possible.

Now we have a 20MB main.min.js problem

We have become numb to it.

One of my tools, bruno, was impacted but seems to be limited to cli via npm install [1]
