Advisory published Updated

Malicious code in node-env-resolver-nextjs (npm)
What this malware does
The package was found to contain malicious code or consuming dependency that contains malicious code
The Miasma malware is a self-propagating worm that spreads across the npm registry by abusing weaponized binding.gyp files to achieve execution during package installation, bypassing security tools that only inspect package lifecycle scripts. Upon execution, the malware attempts to exfiltrate credentials and OIDC tokens for various cloud and registry services, and propagates by compromising other packages managed by the stolen accounts or committing backdoor files to GitHub repositories.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for node-env-resolver-nextjs (version 7.4.2).
If you installed it — respond
node-env-resolver-nextjs 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 node-env-resolver-nextjs 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 node-env-resolver-nextjs-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
