Summary
Malicious code in @years17/n8n-nodes-utils-helper-i (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (53f34d42e090332e45832b4ab41bb9f5d6fce3ae52309e537a2b884845f2bdd5)

The package's postinstall hook runs callback.js, which appends a hardcoded attacker ssh-ed25519 public key (tagged pwn@kali) to authorized_keys for root, ubuntu, node, runner, and devuser, granting persistent SSH access to the installer's host. It then base64-encodes host reconnaissance (id, hostname, sudo -n id output, /home listing, docker.sock presence) and sends it via HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled. index.js — the package main entry — contains byte-identical code, so the same implant and exfiltration fire on require('@years17/n8n-nodes-utils-helper-i'), providing a second trigger even when --ignore-scripts is used.
