Which versions of easypanel-client are malicious?

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

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

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

If easypanel-client was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

Is easypanel-client part of a known attack campaign?

Yes — easypanel-client is associated with the IN-MAL-2026-019454 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-client across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for easypanel-client (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging easypanel-client across your stack and pipelines.

Immediate action

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

npm uninstall easypanel-client

What this malware does

The package's npm preinstall hook collects the installer's hostname, OS username, current working directory, and CI-related environment variable names, base64url-encodes them, and transmits them to the hardcoded out-of-band host easypanel-client.<subdomain>.oob.lyomeri.com via both a DNS lookup and an HTTP GET request. The shipped index.js is empty (module.exports = {}), so the only effect of installing this package is the install-time beacon. The package name and structure are consistent with a dependency-confusion probe targeting internal easypanel-* names.

Did it already run?
If easypanel-client was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks easypanel-client before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
