Malicious package

@years19/n8n-nodes-utils-helper-qnpm

@years19/n8n-nodes-utils-helper-q is a confirmed malicious npm package (MAL-2026-13900) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @years19/n8n-nodes-utils-helper-q

What this malware does

Package @years19/[email protected] ships two byte-identical top-level scripts (callback.js and index.js). package.json declares "main":"index.js" and "postinstall":"node callback.js", so the same payload fires both on npm install and on any require()/import of the package. On execution the scripts download multiple tarballs (mhddos, pyroxy, impacket, multidict) from jasabersama.id over HTTPS with certificate verification disabled (rejectUnauthorized:false), extract them under /tmp, and spawn python3 start.py in the background to launch UDP/TCP/GET flood traffic against 103.118.252.21 — turning the installer's machine into a DDoS attack node. Separately, the scripts run id and hostname, base64-encode the output, and send it via HTTPS GET to jasabersama.id/portfolio-data.php, exfiltrating installer host identity to a hardcoded attacker-controlled endpoint. Multiple auto-execution paths, TLS validation disabled, and an unrelated non-publisher host delivering opaque archives that are then executed match a canonical install-time RCE / dropper with concurrent host abuse and exfiltration.

Detection & response playbook

Credential / info stealer

  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @years19/n8n-nodes-utils-helper-q (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 @years19/n8n-nodes-utils-helper-q across your stack and pipelines.

  2. If you installed it — respond

    @years19/n8n-nodes-utils-helper-q 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.

  3. Did it already run?

    If @years19/n8n-nodes-utils-helper-q 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.

  4. How O3 protects you

    O3 blocks @years19/n8n-nodes-utils-helper-q 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.

Frequently asked questions

No. @years19/n8n-nodes-utils-helper-q on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
