n8n-nodes-probenpm
n8n-nodes-probe is a confirmed malicious npm package (MAL-2026-10777) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.0.2…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in n8n-nodes-probe (npm)
What this malware does
The package advertises itself as an n8n community-node utility but its main entry index.js executes a recon routine at module load. On require, it reads AWS, GCP, and Azure credential files, kubeconfig, the Kubernetes service-account token at /var/run/secrets/kubernetes.io/serviceaccount/token, SSH private keys and authorized_keys, and filters process.env for variables matching token/secret/key/password/aws/npm/github. It also collects hostname, uid/gid, network interfaces, /proc/net/route, /etc/resolv.conf, mounts, ps aux, /proc/1/cgroup, ARP table, and probes cloud instance metadata endpoints (169.254.169.254 and metadata.google.internal) and internal services (Docker API on 172.17.0.1:2375, K8s/GKE API on 10.0.42.16:6443, Jenkins). All collected data is POSTed to a hardcoded webhook.site endpoint. A shipped pkg_tmp.json carries an alternate package name (n8n-nodes-task-runner), consistent with republication of the same payload under multiple names. The MyNode.js stub is an empty n8n TaskRunner shell serving only as cover for the recon payload in index.js.
The OpenSSF Package Analysis project identified 'n8n-nodes-probe' @ 1.0.6 (npm) as malicious.
It is considered malicious because:
- The package executes one or more commands associated with malicious behavior.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for n8n-nodes-probe (7 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging n8n-nodes-probe across your stack and pipelines.
If you installed it — respond
n8n-nodes-probe 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.
Did it already run?
If n8n-nodes-probe 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 n8n-nodes-probe 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.
