I just discovered that there was a security incident involving the eslint-config-prettier package on NPM. It looks like attackers managed to compromise the supply chain and distribute malware through this popular package.
Has anyone else encountered this issue? I’m worried about whether my projects might be affected since I use this package in several applications. What steps should I take to check if my code has been compromised?
I’m also curious about how these supply chain attacks work and what we can do as developers to protect ourselves from similar incidents in the future. Are there any tools or practices that can help detect when packages have been tampered with?
Any guidance on cleaning up potentially infected projects would be really helpful too.
NPM supply chain attacks are getting way too common these days. Beyond checking what you’ve got installed, you should use npm ci with locked dependencies instead of npm install for production. Attackers usually target maintainer accounts or mess with automated publishing workflows. I’ve switched to using Snyk or GitHub’s Dependabot for continuous monitoring rather than just checking at install time. For quick fixes, check any deployments you made during the compromise window and roll back if you’re running affected versions. These attacks love targeting popular utility packages because they reach so many projects - eslint-config-prettier is exactly that type of target. Moving forward, use npm shrinkwrap to lock down your entire dependency tree and regularly audit for weird behavior changes or file size jumps.
whoa, really?? i didn’t hear about this attack! i’ve been using eslint-config-prettier in my apps too. check your package-lock.json for odd versions and run npm audit for vulnerabilities. also keep an eye on your build logs for anything weird.
Had this exact issue with another compromised package last year - learned about supply chain security the hard way. First, check your package.json for the exact eslint-config-prettier version and compare it to the compromised versions listed in the security advisory. For detection, I use npm-audit-resolver and socket.dev to catch suspicious packages before they install. Main red flag I watch for: unexpected network requests or file system access from packages that shouldn’t need them. If you think you’re compromised, nuke your node_modules folder completely, clear npm cache, pin a verified clean version in package.json, then reinstall everything. Also scan your system for weird processes or network connections that might’ve started during the compromise window.
