On execution the code writes a Python UDP/TCP flood script to /tmp/attack.py and launches it via `nohup python3 /tmp/attack.py &`, directing ~650 threads at 103.118.252.21 on ports 80/443 for 600 seconds. In parallel, the code runs `id` and `hostname`, collects process/loadavg indicators, base64-encodes the result, and sends it via `https.get` with `rejectUnauthorized: false` to `https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=<encoded>`. Installer hosts become participants in an outbound DDoS attack while also leaking host identity to a hardcoded endpoint.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-v"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"callback.js","sha256":"2d4a88d7ac61db1d7d9afad967897f9a65e2e2556019e3711f7749d0471ba641","tlsh":"174183e33ab89434d5b32090a8a6ee42a627b10b5586fdd8f04dd6b20f6b03827914f4"},{"path":"package.json","sha256":"17df750e02e28cd3d5d078915800a2dc20e6cc0eb66ca8183aa05d28b078792e","tlsh":"00f055028c720f3321cdab66189a8101aa246e8b949c7c2873cf010c87986b52abe689"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-v-1.0.0.tgz","hashes":{"sha1":"4c87ab95fac21d7c9474ad1120b031ed07616b2d","sha512_sri":"sha512-j6OuXdw9r5qv7DoTQKjudWFiiHcUZtqSpj3C/+okhVLHYVkt3zMErBay23WsmIhzTOvjX2/ep/In5T0b+KAmBw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-v/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017584","import_time":"2026-08-12T15:26:11.878311717Z","modified_time":"2026-08-12T15:08:15Z","sha256":"f50dc2318d26c5626c5a713f65a50d63dfb48340b267b2bcb25583374a3ad282","source":"amazon-inspector","versions":["1.0.0"]}]}}
