Post Mortem: axios NPM supply chain compromise

Not much we didn't know (you're basically SOL since an owner was compromised), however we now have a small peek into the actual meat of the social engineering, which is the only interesting news imho: https://github.com/axios/axios/issues/10636#issuecomment-418...

jasonsaayman and voxpelli had useful write ups from the "head on a swivel" perspective of what to watch out for. Jason mentioned "the meeting said something on my system was out of date." they were using Microsoft meeting and that's how they got RCE. Would love more color on that.

He says it mimicks what is described here: https://cloud.google.com/blog/topics/threat-intelligence/unc...

Which is basically phishing:

> The meeting link itself directed to a spoofed Zoom meeting that was hosted on the threat actor's infrastructure, zoom[.]uswe05[.]us.

> Once in the "meeting," the fake video call facilitated a ruse that gave the impression to the end user that they were experiencing audio issues.

> The recovered web page provided two sets of commands to be run for "troubleshooting": one for macOS systems, and one for Windows systems. Embedded within the string of commands was a single command that initiated the infection chain.

they are cloning Zoom and MS Teams, and try to get people to either copy a script (which is in a textarea that's conveniently too small to show the whole script, and scrollbars are hidden by CSS, and there's a copy button, and when you paste it into the terminal you'll see last few lines, also look innocent, but there's a curl | zsh or `mshta` somewhere in there), download and run a binary/.dmg (and it might be even signed by GoogIe LLC. - the name chosen to look good in the usual typeface used on macOS).

...

it seems the correct muscle memory response to train into people is that "if some meeting link someone sent you doesn't work, then you should create one and send them the link"

(and of course never download and execute anything, don't copy scripts into terminals, but it seems even veteran maintainers do this, etc...)

Arrgh. You're looking at the closest thing to a root cause and you're just waving over it. The culture of "just paste this script" is the problem here. People trained not to do this (or, like me, old enough to be horrified about it and refuse on principle) aren't vulnerable. But you just... give up on that and instead view this as a problem with "muscle memory" about chat etiquette?

Good grief, folks. At best that's security theater.

FWIW, there's also a root-er cause about where this culture came from. And that's 100% down to Apple Computer's congenital hatred of open source and refusal to provide or even bless a secure package management system for their OS. People do this because there's no feasible alternative on a mac, and people love macs more than they love security it seems.

I don't understand. I used Linux for a long time before I switched to Mac, and the "copy this command and paste it in your terminal" trope was just as prevalent there.

by nozzlegear

4/4/2026 at 7:07:18 AM

Most of the copy-paste Linux command used to be 'sudo aptitude install -y blahblah'. It is worth noting though that Ubuntu's PPAs became at some point widespread enough to have pasting a new repo source as a standard practice as well (which would open the way to this kind of attack for sure)

by darkwater

4/4/2026 at 4:33:39 AM

It's really not, and to the extent it is it's an echo of the nonsense filtering from elsewhere. Linux distros went decades without this kind of thing by packaging the popular stuff securely. People who wanted the source knew how to get it. The "just copy this command" nonsense absolutely came from OS X first.

by ajross

4/4/2026 at 6:22:15 AM

Arch has pacman and that worked so well that it had to have AUR which is just glorified curl | bash. Linux distros managed it for decades when the vast majority of binaries you would run are made by nerds for nerds. If the original maintainer isn't willing to securely package it then you're often SOL.

by dj_mc_merlin

4/4/2026 at 1:06:51 PM

AUR (also PPA which another comment cited) is emphatically not the same as "just run this script". If anything, and at worst, it's analogous to NPM: it's an unverified repository where the package is run at the whim of the author, and it leaves you subject to attacks against or by that author.

You still, however, know that the author is who they say they are, and that other people (the distro maintainers) believe that author to be the correct entity, and believe them to have been uncompromised. And any such compromise would, by definition, affect all users of the repo and presumably be detected by them and not by you in the overwhelmingly common case.

"Just run this script" short circuits all of that. YOU, PERSONALLY, ALONE have to do all the auditing and validation. Is the link legit? Did it come from the right place? Is it doing something weird? Was the sender compromised? There's no help. It's all on you. Godspeed.

by ajross

4/4/2026 at 3:28:53 PM

> You still, however, know that the author is who they say they are

This doesn't mean anything since "who they say they are" is an anonymous username with no real life correlation. Might as well be completely anonymous.

> that other people (the distro maintainers) believe that author to be the correct entity

No? Anyone can make an account and upload to AUR and it has exactly 0% to do with the distro maintainers. Packages can be removed if they're malicious, but websites can also be removed via browser-controlled blacklists (which I don't like btw but it's how it works nowadays).

> And any such compromise would, by definition, affect all users of the repo and presumably be detected by them and not by you in the overwhelmingly common case.

This is true of a popular website that advertises install instructions using curl | bash as well.

I've been using Linux for the past 2 decades and my general experience is that it is in no way more secure than Windows or Mac, just way less popular and with a more tech savvy userbase.

by dj_mc_merlin

4/4/2026 at 4:10:41 PM

> This doesn't mean anything since "who they say they are" is an anonymous username with no real life correlation.

No, that's affirmatively incorrect. AUR and PPA both require authenticated accounts. The "real life correlation" may be anonymous to you, but it is trackable in a practical sense. And more importantly, it's stable: if someone pushes an attack to AUR (or NPM, whatever) the system shuts it down quickly.

And the proof is THAT IS EXACTLY WHAT HAPPENED HERE. NPM noticed the Axios compromise before you did, right? QED. NPM (and AUR et. al.) are providing herd protection that the script-paste hole does not.

Those scripts you insist on running simply don't provide that protection. The only reason you haven't been compromised is because you aren't important enough for anyone to care. The second you get maintainership over a valuable piece of software, you will be hacked. Because you've trained yourself to be vulnerable and (especially!) becuase you've demonstrated your softness to the internet by engaging in this silly argument.

An owner being compromised is absolutely survivable on a responsibly run FOSS project with proper commit/review/push signing.

This and every other recent supply chain attack was completely preventable.

So much so I am very comfortable victim blaming at this point.

This is absolutely on the Axios team.

Go setup some smartcards for signing git push/commit and publish those keys widely, and mandate signed merge commits so nothing lands on main without two maintainer sigs, and no more single points of failure.

by lrvick

4/3/2026 at 4:28:25 AM

Did you investigate the maintainer compromise and publication path? The malicious version was never committed or pushed via git. The maintainer signs his commits, and v1 releases were using OIDC and provenance attestations. The malicious package versions were published locally using the npm cli after the maintainer's machine was compromised via a RAT; there's no way for package maintainers to disable/forbid local publication on npmjs.

It seems the Axios team was largely practicing what you're preaching. To the extent they aren't: it still wouldn't have prevented this compromise.

by fortuitous-frog

4/3/2026 at 5:03:01 AM

I can not find a single signed recent commit on the axios repo. It is totally yolo mode. Those "signed by github" signatures are meaningless. I stand by my comment in full.

One must sign commits -universally- and -also- sign reviews/merges (multi-party) and then -also- do multi party signing on releases. Doing only one step of basic supply chain security unfortunately buys you about as much defense as locking only a single door.

I do however certainly assign significant blame to the NPM team though for repeatedly refusing optional package signing support so packages with signing enabled can be refused at the server and client if unsigned by a quorum of pinned keys, but even aside from that if packages were signed manually then canary tools could have detected this immediately.

by lrvick

4/3/2026 at 7:05:05 AM

What you sign or don't sign in your Git repo doesn't matter because NPM doesn't publish from a Git repo. Signing commits is still useful for your contributors and downstream forks but it won't have any effect on the users who use your package via NPM.

I think NPM is fully to blame here. Packages that exceed a certain level of popularity should require signing/strong 2FA. They should implement more schemes that publishers can optionally enable, like requiring mandatory sign-off from more than 1 maintainer before the package is available to download.

Then on the package page it should say: "[Warning] Weak publishing protection" or "[Checkmark] This package requires sign-off from accountA and accountB to publish".

by dns_snek

4/3/2026 at 9:22:32 AM

2FA was mandated by npm

they had 2FA, but likely software TOTP (so it was either autofilled via 1password (or similar), or they were able to steal the seed)

at this point I think publishing an npm app and asking people to scan a QR with it is the easiest way (so people don't end up with 1 actual factor)

by pas

4/3/2026 at 8:37:34 PM

What they need to mandate is hardware anchored passkeys/fido2/webauthn for both auth and package signing, with the -option- to sign with PGP for those that have well trusted PGP keys.

They won't do this, I have talked to them plenty of times about it. But, if they did, the supply chain attacks would almost entirely stop.

by lrvick

4/4/2026 at 9:09:31 AM

Don't need to require hardware 2fa tokens. Just a mobile app would be sufficient. Publish to a staging area then require confirmation on mobile to make it go live. Maybe include a diff of changes files for good measure.

by zarzavat

4/5/2026 at 12:11:02 PM

And even a mobile app (or, in fact, any single-person 2FA) would be unnecessary if we had a requirement for another live person to approve the release. As a bonus, a two-maintainers-required setup would also improve resilience against one of them going rogue or getting tortured.

by patrakov

4/3/2026 at 6:49:12 PM

So you think the answer is replacing a requirement for a 6-digit 2FA code that can be typed into the npm publishing CLI with a requirement for a device that has a camera that can scan a QR code and then... what? What does the QR code do on the device? How does the npm CLI present the QR code?

by HumanOstrich

4/4/2026 at 12:51:02 AM

Simply supporting passkeys gives people domain locked login via qr/phone, or any fido2 usb device. No more keyboard entry required for login other than username, which means phishing is off the table. Standards are great if we can get anyone to use them.

by lrvick

4/3/2026 at 7:57:32 PM

Like I said. One must sign commits -universally- and -also- sign reviews/merges (multi-party) and then -also- do multi party signing on releases. The code in the release must match the code from git, or no publish.

Until NPM can enforce those basic checks though, you have to roll your own CI to do it yourself, but large well funded widely used projects have an obligation to do the basics to protect their users, and their own reputations, from impersonation.

by lrvick

4/4/2026 at 6:12:32 AM

I agree, I just think it's pointless to discuss Axios' commit-signing practices or lack thereof when NPM doesn't support any of it. It seems like axios was already using Trusted Publishing [1] and it still didn't get caught.

You said that you "also" blame NPM, but they're the only party who should get any blame until they get their shit together.

It wasn’t done through git. It was a direct npm publish from the compromised machine. If you read further down in the comments (https://github.com/axios/axios/issues/10636#issuecomment-418...), it seems difficult to pick the right npm settings to prevent this attack.

If I understand it correctly, your suggestions wouldn’t have prevented it, which is evidence that this is not as trivially fixable as you believe it is.

by TheTaytay

4/3/2026 at 5:17:31 AM

To prevent supply chain attacks you need multi party cryptographic attestation at every layer, which is pretty straight forward, but you are correct, NPM and GitHub controls absolutely will not save you. Microsoft insists their centralized approach can work, but we have plenty of evidence it does not.

Operate under the assumption all accounts will be taken over because centralized corporate auth systems are fundamentally vulnerable.

This is how you actually fix it:

1. Every commit must be signed by a maintainer key listed in the MAINTAINERS file or similar

2. Every review/merge must be signed by a -second- maintainer key

3. Every artifact must be build deterministically and be signed by multiple maintainers.

4. Have only one online npm publish key maintained in a deterministic and remotely attestable enclave that validates multiple valid maintainer signatures

5. Automatically sound the alarm if an NPM release is pushed any other way, and automatically revoke it.

by lrvick

4/3/2026 at 5:40:51 AM

And for 5 there should be help on the NPM end to make it so that the alarms can fire before the new update is actually revealed to the public. There could be a short staging time where it could be revoked before any harm has been done. During this staging time NPM should also scan the package through a malware scanner before allowing it to go public.

by charcircuit

4/3/2026 at 8:04:06 PM

I agree that would be nice, but NPM absolutely will not do any basic supply chain integrity work. They are actively opposed to it citing concerns that it might turn off lower skill developers that would be too annoyed by tapping a yubikey to sign releases or code. I have talked to them enough times over the years to have completely given up here.

Whats even more stupid is they actually started mandating 2FA for high risk packages, and FIDO2 supports being used to actually sign artifacts, but they instead simply use it for auth, and let releases stay unsigned. Even the developers they insisted hold cryptographic signing keys, they insist on only throw-away signatures for auth, but not using them for artifact signing to prevent impersonation. It is golf clap level stupid.

Consider them a CDN that wants to analyze your code for AI training for their employer and nothing more. Any security controls that might restrict the flow of publishing even a little bit will be rejected.

by lrvick

4/5/2026 at 12:03:17 PM

The "nothing gets on main without two signatures" rule would not have prevented the xz story, where a comaintainer was able to smuggle malicious code past the review as "binary data for new tests" and, effectively, get it signed.

by patrakov

4/3/2026 at 2:21:42 PM

This only works up to a point. Some human needs some way of changing the publication setup in case something goes wrong or changes. What you're asking is blowing a proverbial e-fuse once the setup is known to be working. This is software, shit will go wrong at some point and you need a way to make changes.

by Zopieux

4/4/2026 at 12:53:12 AM

Of course, which is why all the (decent) tooling for this is provider agnostic, and provides documentation for multi-party-sharded backups so a quorum of maintainers can always re-assemble the key by hand for any reason if needed.

by lrvick

4/4/2026 at 3:50:24 AM

The fetch api has been widely available in browsers for a decade now. And in node since 18. A competent developer could whip up a more axios-like library with fetch in a day easily. You can do all the cool things like interceptors with fetch too.

Yet most developers I work with just use it reflexively. This seems like one of the biggest issues with the npm ecosystem - the complete lack of motivation to write even trivial things yourself.

by falkensmaize

4/4/2026 at 6:30:11 AM

> A competent developer could whip up a more axios-like library with fetch in a day easily.

Then you would have created just an axios clone. AKA re-inventing the wheel. The issue isn't the library itself, but rather the fact that it's popular and provided a large enough attack surface.

You can actually just clone the axios package and use it as is from your private repo and you would not have been affected.

The wheel is the native fetch API, nobody needs to reinvent it.

All you'd do in that scenario is make your own hubcap to put on top.

by littlestymaar

4/4/2026 at 7:20:12 AM

I really don't get this either, I've always removed axios when it was preinstalled in a framework.

I use "xhr" via fetch extensively, it can do everything in day to day business for years with minimal boilerplate.

(The only exception known to me being upload progress/status indication)

by kro

4/4/2026 at 11:50:24 AM

Axios really does a lot of other great things. I would argue that Fetch could’ve easily been Axios-lite. Axios handles errors better, has interceptors, parses JSON for you, etc.

The multiple supply chain attacks against NPM packages would, of course, be solved if we simply stop using third-party libraries.

by port11

4/5/2026 at 3:39:53 AM

I guess the point I’m making is that a lot of popular JavaScript libraries were created to address deficiencies in the core api that don’t exist anymore, but we keep using these libraries mostly because of entropy and familiarity.

by falkensmaize

4/7/2026 at 7:02:35 AM

True. In my case it’s also out of general tiredness and disinterest. A good newsletter that catches up on useful things in the ecosystem might help, otherwise I can’t be bothered anymore to keep up. 5 years ago that still seemed like a good way to spend my time. I wonder if other developers are just as jaded.

The interesting detail from this thread is that every legitimate v1 release had OIDC provenance attestations and the malicious one didn't, but nobody checks. Even simpler, if you're diffing your lockfile between deploys, a brand new dependency appearing in a patch release is a pretty obvious red flag.

by robshippr

4/3/2026 at 4:51:43 AM

To be honest, I would have assumed the tooling would do attestation verification for me. The diffing the lockfile would be on me though.

by GCUMstlyHarmls

4/3/2026 at 3:36:05 AM

npm could solve half of this by letting packages opt into OIDC-only publishing at the registry level. v1 already had provenance attestations but the registry happily accepted the malicious publish without them.

Looks like a very sophisticated operation, and I feel for the maintainer who had his machine compromised.

The next incarnation of this, I worry, is that the malware hibernates somehow (e.g., if (Date.now() < 1776188434046) { exit(); }) to maximize the damage.

by anematode

4/3/2026 at 10:33:07 AM

Isn't that already how it is?

I mean the compromised machine registers itself on the command server and occasionally checks for workloads.

The hacker then decides his next actions - depending on the machine they compromised they'll either try to spread (like this time) and make a broad attack or they may go more in-depth and try to exfiltrate data/spread internally if eg a build node has been compromised

by fraywing

4/3/2026 at 2:00:25 AM

That's the reality of modern war. Many countries are likely planting malware on a wide scale. You can't even really prove where an attack originated from, so uninvolved countries would also be smart to take advantage of the current conflict. Like if you primarily wrote German, you would translate your malware to Chinese, Farsi, English, or Hebrew, and take other steps to make it appear to come from one of those warring countries. Any country who was making a long term plan involving malware would likely do it around this time.

by altmanaltman

Yes and there have been documented cases of translated malware. Sometimes its done a little sloppily and there is other evidence that points to the origin being in another country that doesn't speak the language its written in. But even then, you can't really prove they didn't just use a residential VPN or whatever.

npm process to setup OIDC is way too frustrating. There is just so much friction. You need the package to first exists in the registry, meaning you have to first create an API token and push something. And only then can you enable OIDC for that specific package. After adding the repo + workflow names, you have to save. Then finally toggle the “only allow OIDC publishing”.

Before each action you need to enter your 2fa code.

I got so frustrated with npm end of last year that I wrote a whole guide covering that issue: https://npmdigest.com/guides/npm-trusted-publishing

by ipnon

4/3/2026 at 2:28:42 AM

It’s far from a complete solution, but to mitigate this specific avenue of supply chain compromise, couldn’t Github/npm issue single-purpose physical hardware tokens and allow projects (or even mandate, for the most popular ones) maintainers use these hardware tokens as a form of 2FA?

by dcrazy

4/3/2026 at 2:54:01 AM

What would a physical token give you that totp doesn't?

Edit: wait, did the attacker intercept the totp code as it was entered? Trying to make sense of the thread

by yjftsjthsd-h

4/3/2026 at 3:24:31 AM

The attacker installed a RAT on the contributor’s machine, so if they had configured TOTP or saved the recovery codes anywhere on that machine, the attacker could defeat 2FA.

by dcrazy

4/3/2026 at 5:07:57 AM

Oh, yes, I missed that the TOTP machine was compromised:\ Would that then imply that it would have been okay if codes came from a separate device, eg. a TOTP app on a Palm OS device with zero network connectivity? (Or maybe these days the easiest airgapped option is an old android phone that stays in airplane mode...)

by yjftsjthsd-h

I would argue that the problem is network accessibility, not programmability.

When designing a system for secure attestation, end-user programmability is not a feature.

It would not be an advantage for your front door lock to be infinitely reprogrammable. It’s just a liability.

by dcrazy

4/3/2026 at 6:07:06 AM

I mean, I guess attestation might have some value, but it feels like moving the goalposts. Under the threat model of a remote attacker who can compromise a normal networked computer, I can't think of an attack that would succeed with a programmable TOTP code generator that would fail if that code generator was not reprogrammable. Can you?

> It would not be an advantage for your front door lock to be infinitely reprogrammable. It’s just a liability.

Er, most door locks are infinitely reprogrammable, because being able to rekey them without having to replace the whole unit is a huge advantage and the liability/disadvantage is minimal (falling under "It rather involved being on the other side of this airtight hatchway" in an unusually almost-literal sense where you have to be inside the house in order to rekey the lock, at which point you could also do anything else).

by yjftsjthsd-h

4/3/2026 at 6:38:17 AM

Sorry, attestation is the goalpost. The community wants certainty that the package was published by a human with authority, and not just by someone who had access to an authority’s private keys. That is what distinguishes attestation from authentication or authorization.

by dcrazy

4/3/2026 at 5:29:32 AM

Yes, unfortunately authenticator apps just generate TOTP codes based on a binary key sitting in plain sight without any encryption. Not that it would help if the encrypting/decrypting machine is pwned.

All maintainers need to do is code signing. This is a solved problem but the NPM team has been actively rejecting optional signing support for over a decade now. Even so maintainers could sign their commits anyway, but most are too lazy to spend a few minutes to prevent themselves from being impersonated.

If the solution is 'maintainers just need to do xyz', then it's not a solution, sorry. It's not scalable and which projects become 'successful' and which maintainers accidentally become critical parts of worldwide codebases, is almost pure chance. You will never be able to get all the maintainers you need to 'just' do xyz. Just like you will never be able to get humans to 'just' stop making mistakes. So you had better start looking for a solution that doesn't rely on humans not making mistakes.

It scales just fine for thousands of maintainers of thousands of packages for every major linux distribution that powers the internet. You just have to automate enforcement so people do not have a choice.

Are you really saying there is just something fundamental about javascript developers that makes them unable to run the same basic shell commands as Linux distribution maintainers?

by lrvick

4/4/2026 at 3:16:20 AM

No, it really doesn't scale that well. 'Thousands' of packages is laughable compared to the scale of npm. And even at the 'thousands' scale distros are often laughably out of date because they're so slow to update their packages.

You are of course right that a signed package ecosystem would be great, it's just that you're asking people to do this labour for you for free. If you pay some third party to verify and sign packages for you? That's totally fine. Asking maintainers already under tremendous pressure to do yet another labour-intensive security task so you can benefit for free? That's out of balance.

Are they incapable of doing it? Probably not. Does it take real labour and effort to do it? Absolutely.

My 7 teammates and I on stagex actually maintain all this zero-trust signing and release process I am suggesting for several hundred packages and counting. Not asking anyone to do hundreds like my team and I are, but if authors could just at least do the bare minimum for the code they directly author that would eliminate the last gaping hole in the supply chain.

With what keys, and how do you propose establishing trust in those keys?

(As we’ve seen from every GPG topology outside of the kinds of small trusted rings used by Linux distros and similar, there’s no obvious, trustworthy, scalable way to do decentralized key distribution.)

by woodruffw

4/4/2026 at 4:44:13 AM

If the keys that signed the early commits of a trusted FOSS project suddenly change without being signed by the previous keys, that should merit a higher level of consensus at release time, or waiting periods, etc.

Identity continuity at a minimum, is of immense defensive value even though we will not know if the author is human or trusted by any humans.

That said any keys that become attached to projects that are highly depended on would earn a lot of trust that they are human by getting a couple of the 5k+ of people worldwide with active well trusted PGP keys to sign theirs via conferences or otherwise, as it has always been.

> If the keys that signed the early commits of a trusted FOSS project suddenly change without being signed by the previous keys, that should merit a higher level of consensus at release time, or waiting periods, etc.

Two immediate problems: (1) package distribution has nothing to do with git (you don’t need to use any source control to publish a package on most indices, and that probably isn’t going to change), and (2) this doesn’t easily account for expiry, revocation, or the more basal reality that most people just aren’t good at key management. I think a workable design can’t make these assumptions.

> That said any keys that become attached to projects that are highly depended on would earn a lot of trust that they are human by getting a couple of the 5k+ of people worldwide with active well trusted PGP keys to sign theirs via conferences or otherwise, as it has always been.

This doesn’t scale to graphs of hundreds of thousands of maintainers, like PyPI has. I’m also not convinced it’s ever really worked on smaller scales either, except it in the less useful “nerd cred” sense.

by woodruffw

4/6/2026 at 5:52:27 AM

> (1) package distribution has nothing to do with git

It does in stagex, and could in any project. The same maintainer keys that sign commits and reviews are the same keys that must sign releases.

> (2) this doesn’t easily account for expiry, revocation, or the more basal reality that most people just aren’t good at key management. I think a workable design can’t make these assumptions.

I do not accept this excuse. People keep up with passports and birth certificates and you are generally not allowed to have backups of those. I for one am not going to assume that most programmers are incapable of writing down 24 english words on paper on as many backups as the need and being able to recover at least one of those in the future if needed to recover a key.

If a developer really cannot keep track of something so trivial, I absolutely do not trust them not to get their identity stolen by someone seeking to push a supply chain attack

> This doesn’t scale to graphs of hundreds of thousands of maintainers, like PyPI has. I’m also not convinced it’s ever really worked on smaller scales either, except it in the less useful “nerd cred” sense.

Say that to the 5444 PGP keys in the current web of trust that signs and maintains most packages for every major linux distribution running the bulk of the services on the internet. It works just fine.

Simply make it a hard requirement for popular dependencies and developers that cannot figure out how to type 2 commands to generate a key and put it on a smartcard, and write down a 24 word backup, should not be maintainers,

That may sound harsh, but being a maintainer of popular FOSS means an obligation to do the bare minimum to not get your identity stolen, like signing code and releases.

Last century doctors all balked at the idea of washing hands or tools between patients even though it provably resulted in better health outcomes on average.

"But look, everyone is negligent, and they are not likely to change" is not an excuse to not adopt obvious massive harm reduction with little effort.

My team and I practice everything I am preaching here and any responsible project can do the same to protect their projects even if the majority ignorantly do not.

For better or worse, you do trust people like this (assuming you're running a nonzero amount of Python, Ruby, Rust, or whatever else software).

> Say that to the 5444 PGP keys in the current web of trust that signs and maintains most packages for every major linux distribution running the bulk of the services on the internet. It works just fine.

That's tiny, and is exactly my point: these kinds of small rings of trust don't remotely resemble the trust topology in a free-for-all packaging ecosystem.

> "But look, everyone is negligent, and they are not likely to change" is not an excuse to not adopt obvious massive harm reduction with little effort.

This is not the argument being advanced. The argument is that we need to do better (in terms of misuse-resistance, etc.) than long-lived keys and the kinds of nerd-cred "get good" assumptions made in PGP-style webs of trust.

Nobody thinks that signing is bad; the problem is when you push the median developer to adopt it without any clear contingency plans for when, not if they fail to uphold the invariants you assume.

by woodruffw

4/7/2026 at 5:59:24 AM

It is clear the options are either we get better at decentralized trust and decentralized identity recovery, or we all just sit around and wait for a centralized corporation to decide what identity is online, and what minimum security level is good enough for every threat model.

Waiting for corpos to fix it has not worked in one entire forever, so I would rather lower the barrier of entry to decentralized systems that are still an IETF standard securing the backbone of the internet.

At the end of the day there are only tens of thousands of authors of globally deployed FOSS libraries and we absolutely can and must scale cryptographic identity to them to avoid supply chain attacks that hit _everything_.

Secondly, we should double down and not put all the pressure on authors. We need to make it easy for anyone with a reputable key to review and sign any FOSS code that exists. A decentralized and standardized audit system. Working on an implementation of that right now in fact.

Seems to me the root of the problem was that the guy was using the same device for all sorts of stuff.

Seems to me that one drastic tactic NPM could employ to prevent attacks like this is to use hardware security. NPM could procure and configure laptops with identity rooted in the laptop TPM instead of 2FA. Configure the NPM servers so that for certain repos only updates signed with the private key in the laptop TPM can be pushed to NPM. Each high profile repo would have certain laptops that can upload for that repo. Set up the laptop with a minimal version of Linux with just the command line tools to upload to NPM, not even a browser or desktop environment. Give those laptops to maintainers of high profile repos for free to use for updates.

Then at update time, the maintainer just transfers the code from their dev machine to the secure laptop via USB drive or CD and pushes to NPM from the special laptop.

by pas

4/4/2026 at 7:53:34 AM

NPM should fix this mess.

Adding postinstall should require approval from NPM. NPM clients should not install freshly published packages. NPM packages should be scanned after publishing. High profile packages should verify upstream git hash signature. NPM install should run in sandbox and detect any attempt to install outside project directory.

But npm being part of multi trillion company cannot be bothered to fix any of these. Instead they push for tighter integration with GitHub with UX that suck.

by cromka

4/4/2026 at 8:14:20 AM

In cases like this that isn’t an issue, NPM takes the malicious package down and you roll back to the previous version.

The problem would be new versions that fix security issues though, and because this is all open source as soon as you publish the fix everyone knows the vulnerability. You wouldn’t want everyone to stay on the insecure version with a basically public vulnerability for a week.

This could be controlled by npm. Client ask for available versions anyway. If package is security fix then it can be made available instantly. But this delay gives time for security scanners and time to notify maintainers that package was published.

No. axios (v1 at least; not v0) were setup to publish via OIDC, but there's no option on npmjs for package maintainers to restrict their package to *only* using OIDC. The maintainer says his machine was infected via RAT, so if he was using software-based 2FA, nothing could have prevented this.

by fortuitous-frog

4/3/2026 at 12:52:46 PM

Actually there is an option to restrict to only OIDC publishing. It is a bit hidden and relies on a different form for reasons I really cannot understand. Npm UX is just so bad.

by dgellow

4/3/2026 at 7:20:41 AM

Nope, the most restrictive option available is to disallow tokens and require 2FA. I think that using exclusively hardware 2FA and not having the backup codes on the compromised machine probably would have prevented this attack though.

by mcintyre1994

4/3/2026 at 11:54:54 AM

Someone in the linked Github thread describes an attack where the attackers waited for the victim to use their Yubikey for an AWS login, giving the attackers access to AWS as well. I don't think hardware 2FA is safe against a RAT.

by pepve

4/4/2026 at 11:56:20 AM

Logins are session-based. You could tie publishing of a package to a signature from the key, then 1 tap = 1 package hash. But yeah, if the system is compromised and the attacker is doing interactive attacks they can wait for something that requires using the key and then trigger the publishing and win a race against the real prompt. To the user it might just appear like having to tap twice.

The interesting detail from the GitHub thread is shaanmajid's observation that every legitimate v1 release had OIDC provenance attestations and the malicious one didn't, but nobody checks.

They have basic obligations as highly trusted FOSS software maintainers, a role they allowed themselves to be elected into, to make sure their hard earned goodwill and trust is not stolen by a bad actor. They also have a basic obligation to make sure they have accountability and review of all code before it gets to their users.

Sitting back and expecting Microsoft to keep the community safe is going to continue to end badly. The community has an obligation to each other.

Like, no one is making someone go bring a bunch of food to feed the homeless, but if you do, you have some basic social obligation to make sure it is sanitary and not poison.

A $50 used laptop from goodwill and a $40 yubikey will do the job.

If maintainers really cannot afford that, they should flag it as a major big bold print supply chain risk on the readme: "We cannot afford 4 yubikeys for our maintainers and thus all code is signed with software keys in virtual machines as a best effort defense. Donate to our fund [here] to raise $500 for dedicated release hardware"

Friends and I have gotten 100s of yubikeys and nitrokeys donated to FOSS maintainers, but FOSS maintainers have to be willing to say they would use them and signal that they need them.

Honestly though, anyone that cannot afford $40 I expect is at high risk of being bribed or having to give up contributing to take on more work, so we should significantly fund any project signaling that much desperation.

No. As a user of your package, I want assurance that the package you publish does what it says it does and does not contain malware. This is different from the package having been published by you. I want protection against you going rogue, not only from you being impersonated. 2FA on your side does not protect me against you going rogue. A comaintainer does.

So the correct quote would be: Anyone that cannot find a comaintainer to review all the code and to prevent deliberate sabotage has absolutely no business writing widely depended upon FOSS software.
