MAL-2026-10777 Malicious code in n8n-nodes-probe (npm)

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:
