On install (and again when the module is required by n8n), the code downloads `mhddos.tgz` and `get-pip.py` from https://jasabersama.id/assets/cache/.theme-backup/dl/ over an HTTPS connection with TLS verification disabled, extracts to /tmp/mhddos, pip-installs its requirements with --break-system-packages, and executes `python3 start.py` — the MHDDoS DDoS tool. Before the drop, callback.js/index.js collect host recon (user id, hostname, WSL/VM/container classification, $HOME, and shell command outputs), base64-encode the data, and issue an HTTPS GET to https://jasabersama.id/portfolio-data.php with the recon in the `c` query parameter. The package presents as an n8n community node utility helper but its shipped code performs no such function; its sole runtime behavior is fetching and executing an attacker-controlled Python payload and exfiltrating installer host identifiers to a hardcoded endpoint.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/n8n-nodes-utils-helper-j"},"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":"8652c6eb26f419729cae5eaa04db4fea4d8c06a7d784fe3372247472b5d9c529","tlsh":"e04166b91261a138457371942f2bdb1a956ff10750c4aec8f74e43b38f1252c992b66c"},{"path":"index.js","sha256":"8652c6eb26f419729cae5eaa04db4fea4d8c06a7d784fe3372247472b5d9c529","tlsh":"e04166b91261a138457371942f2bdb1a956ff10750c4aec8f74e43b38f1252c992b66c"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-j-1.0.0.tgz","hashes":{"sha1":"ec5d51c356260ce1e5bb0bee30f79ecbd5074550","sha512_sri":"sha512-YsIYad5r4shwenO9ttNRcq9mWGQdOdlYD5HVh792ej4NLkXcsuRNhwKy2coDB3S9LNm8SovSXDWvY++pULl9og=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-j/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017407","import_time":"2026-08-12T12:24:10.651724829Z","modified_time":"2026-08-12T12:17:20Z","sha256":"c17b5de9890a54a8a7a1ddf14ff05488baa64612904cf577591e1b9f9a007f1a","source":"amazon-inspector","versions":["1.0.0"]}]}}
