Which versions of easypanel-api-client are malicious?

The following npm versions of easypanel-api-client are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate easypanel-api-client if I installed it?

easypanel-api-client 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 easypanel-api-client — how do I know if it already compromised me?

If easypanel-api-client 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 easypanel-api-client part of a known attack campaign?

Yes — easypanel-api-client is associated with the IN-MAL-2026-019841 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 easypanel-api-client across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for easypanel-api-client (version 1.0.0).

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall easypanel-api-client

What this malware does

The package ships an empty library body (index.js exports {}) and a preinstall lifecycle script that runs automatically on npm install. The preinstall script collects installer-side identifiers — hostname, username, current working directory, and the names of CI-related environment variables — base64url-encodes them, and transmits them via both a DNS lookup and an HTTP request to a subdomain of oob.lyomeri.com (e.g. easypanel-api-client.<encoded-chunk>.oob.lyomeri.com, with the HTTP variant POSTing to /npm/<encoded>). The package has no functional code beyond this beacon, matching the dependency-confusion / namespace-squat research-beacon shape targeting internal package names.
