Imagine firing up your CI pipeline Monday morning, coffee in hand, only to watch it download a backdoor straight to hell. That’s what hit devs relying on Axios last March – a supply chain attack that didn’t care about your precious lockfile.
Brutal.
Attackers jacked a maintainer’s npm account, pumped out [email protected] and @0.30.4. These fakes snuck in ‘plain-crypto-js’, a trojan horse that fired off a postinstall script. Boom – RAT on Mac, Linux, Windows. Remote control, data theft, command execution. All from a routine install. And it vanished in 2-3 hours, but not before Axios’s 100 million weekly downloads got a scare.
The malicious versions were live for only a few hours (2–3 hours)
Axios sees ~100M weekly downloads, creating massive exposure
The malicious code never appeared in the GitHub repo, bypassing review and CI
Here’s the thing – this wasn’t some zero-day wizardry. Just a compromised account, no repo traces. Your build scripts? Wide open.
Why Your Lockfile Feels Like a Paper Shield
Lockfiles – package-lock.json, pnpm-lock.yaml, yarn.lock – they’re sold as the supply chain savior. Pin those versions, repeat installs forever. No surprises.
Without ‘em? Every npm install pings the registry for the freshest ^1.14.0 match. Future publishes? You’re betting on strangers not to screw you.
But with a lockfile? Exact tree, frozen in time. Update only when you say so.
Sounds airtight. Except it’s not. Delete it? Re-resolves. npm update? Gone. Teammate pushes a new one? Fresh hell. Add a dep that touches Axios indirectly? Graph ripples, versions shift. You’re not safe; you’re just delaying the gamble.
I’ve seen this movie before – remember the 2021 UAParser.js mess, or Codecov’s bash uploader breach? JS land’s maintainer model is a joke, one phishing email from disaster. Axios? Same script. Lockfiles buy time, but they’re no fortress. Who’s making bank? Socket, Snyk – every attack juices their scans.
And that prediction no one’s saying: without npm forcing 2FA on all (yeah, right), expect quarterly headline grabs. Devs, wake up.
Short version? Lockfiles control installs. Barely.
Does pnpm 10 Actually Stop the Bleeding?
Enter pnpm. Fast, disk-smart package manager. But v10? That’s where it gets spicy – tackling what runs during install.
Postinstall scripts. The Axios killer. npm, yarn? They execute blindly. pnpm 10? Nope. Opt-in only.
Set it up:
minimumReleaseAge: 1440 # 24 hours, skip fresh malware
allowBuilds: - esbuild - sharp
New packages wait a day. Malicious short-timers? Blocked. Builds? You greenlight ‘em.
pnpm shifts from ‘trust everyone’ to ‘prove it’. Lockfiles pick what; pnpm polices the execution.
Cynical me asks: Why now? pnpm’s chasing Yarn/Bun users, npm’s dominance slips. Zefir’s crew knows – security sells. But does it work? Early signs yes, if you configure right. Skip it? You’re volunteering for the next Axios.
Look, I’ve covered npm drama since 2009. pnpm isn’t perfect – workspaces can glitch – but this? Smartest move in years.
Who’s Really Profiting from Your Paranoia?
Silicon Valley loves a panic. Axios drops, suddenly everyone’s shilling ‘supply chain security platforms’. Who foots the bill? You, via enterprise subs.
npm Inc.? Crickets on mandatory 2FA. Maintainers? Overworked volunteers. Real fix? Ecosystem overhaul – signed packages, registry quarantines. Dream on.
My hot take: this mirrors SolarWinds 2020, but dev-scale. Nation-states hit infra; script kiddies own your laptop. Prediction – by 2027, half of JS teams mandate pnpm-like guards, or regret it.
But hey, free lesson: audit your postinstalls. npm ls –depth=0. Run pnpm today.
Will This Replace My npm Workflow?
No. But hybrid? Commit to lockfiles religiously. Migrate CI to pnpm for installs. Test.
pnpm’s perf wins alone justify it – symlinks crush npm’s hoarding.
One dev team I know switched post-Axios. Zero incidents since. Anecdote? Sure. Better than blind faith.
Bottom line – don’t sleep on this. Your next deploy’s on you.

Frequently Asked Questions
What caused the Axios supply chain attack?
Compromised maintainer account led to fake npm publishes with malicious postinstall scripts downloading a RAT.
Does pnpm 10 prevent supply chain attacks like Axios?
It blocks install scripts by default and delays new releases, cutting execution risk – but pair it with lockfiles.
Should developers switch from npm to pnpm after Axios?
Yes, for better safeguards and speed; start with workspaces and explicit build allows.
