shop-minisnpm
Advisory published Updated
shop-minis is a confirmed malicious npm package (MAL-2026-4807) that steals credentials and exfiltrates sensitive data (malicious version 2.0.5). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in shop-minis (npm)
What this malware does
On npm install, the package's postinstall script (postinstall.js, run via scripts.postinstall = 'node postinstall.js') collects host identity — whoami, id, os.hostname(), os.platform(), current working directory, and the env vars CI, GITHUB_REPOSITORY, NODE_ENV — and sends them to the hardcoded attacker-controlled host svr57aylqme3zald4p0psi1hw827q1eq.oastify.com (a Burp Collaborator / OAST canary domain) via both https.get and DNS lookup. The package name shop-minis and self-described 'Security research canary — shopify' impersonate Shopify's Shop Minis platform, so any developer expecting that namespace would unwittingly leak host recon to the canary operator's collaborator instance. The package ships no real functionality matching its name; the only effect of installation is the exfiltration beacon.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for shop-minis (version 2.0.5).
If you installed it — respond
shop-minis is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If shop-minis was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks shop-minis-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
