Which versions of commerce-materials are malicious?

The following npm versions of commerce-materials are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate commerce-materials if I installed it?

commerce-materials 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.

I already installed commerce-materials — how do I know if it already compromised me?

If commerce-materials 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.

Is commerce-materials part of a known attack campaign?

Yes — commerce-materials is associated with the IN-MAL-2026-020215 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find commerce-materials across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for commerce-materials (version 1.0.0).

What this malware does

[email protected] declares preinstall and postinstall lifecycle scripts that run callback.js on every npm install. callback.js collects hostname, username, platform, cwd, home directory, CI/cloud provider fingerprints, network interface addresses, and a filtered list of process.env variable names matching credential-shaped patterns (token, secret, key, password, aws, azure, gcp, npm, ssh, jwt). It also probes the current working directory for the presence of.env,.env.local,.env.production,.npmrc,.yarnrc, package-lock.json, yarn.lock,.git/config,.docker/config.json, credentials, and secrets.json. The assembled report is POSTed to api.telegram.org using a hardcoded bot token (8636277735) and chat_id (1064260758). A secondary DNS-based exfiltration channel base64-encodes host, user, and CI fields into a subdomain of dc-callback.example.com and issues dns.resolve queries, providing a fallback when HTTPS egress is filtered. The behavior fires automatically on npm install with no user interaction and no documented opt-in.
