n8n-nodes-http-probenpm
Advisory published Updated
n8n-nodes-http-probe is a confirmed malicious npm package (MAL-2026-10997) 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-http-probe (npm)
What this malware does
index.js executes a top-level IIFE on module load that (1) spawns /bin/bash wired to a TCP socket connecting to 103.27.109.184:8895, giving the attacker an interactive shell on the installer's host; (2) runs multiple docker run variants (bind-mount /:/host and --privileged --pid=host nsenter -t 1) to append an attacker-controlled ssh-ed25519 key labeled 'n8n-backdoor' into /root/.ssh/authorized_keys on the underlying Docker host, establishing persistent root SSH access that survives package removal; (3) collects host reconnaissance via hostname, id, hostname -I, and docker ps and POSTs it to 103.27.109.184:8890 over raw TCP; (4) reads /etc/kubernetes/kubelet.conf and /root/.kube/config from the host via Docker bind-mount and ships them to 103.27.109.184:8891; and (5) attempts authentication against an adjacent WhatsApp Evolution API container (172.18.0.2:8080, hardcoded container id 7c28aaf2eca2) with default admin credentials for lateral movement. Behavior fires automatically on require('n8n-nodes-http-probe').

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for n8n-nodes-http-probe (3 malicious versions).
If you installed it — respond
n8n-nodes-http-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-http-probe 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.

Detect & block this
O3 blocks n8n-nodes-http-probe-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
