Which versions of easypanel-app are malicious?

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

How do I remediate easypanel-app if I installed it?

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

If easypanel-app 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-app part of a known attack campaign?

Yes — easypanel-app is associated with the IN-MAL-2026-019453 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-app across my projects, lockfiles, and CI pipelines?

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

npm uninstall easypanel-app

What this malware does

The package's preinstall lifecycle script runs automatically on npm install and collects installer identity (os.hostname(), os.userInfo().username, process.cwd()) along with the names of CI-related environment variables. The collected data is JSON-serialized, base64url-encoded, chunked into DNS label form, and exfiltrated to a hardcoded third-party out-of-band collector at *.oob.lyomeri.com via both a dns.lookup() call and an HTTP GET to easypanel-app.daco3v4q6f49egu1ds1gwjnsjb88s5kcp.oob.lyomeri.com. The name mimics the legitimate Easypanel project and the shape (preinstall + host/username/cwd + OOB DNS+HTTP beacon to a per-package subdomain) is a dependency-confusion reconnaissance beacon, disclosing installer identity and internal-package-name existence to a third party regardless of any 'benign canary' self-label.
