The dropped payload is the PyRoxy / MHDDOS DDoS attack framework. The same postinstall collects the output of `id` and `hostname`, base64-encodes the result, and sends it via HTTPS GET (certificate verification disabled) to jasabersama.id/portfolio-data.php with a hardcoded key parameter. The package presents itself as an n8n community utility node, but the delivered payload is unrelated offensive tooling.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/n8n-nodes-utils-helper-r"},"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":"fdc80c96df674dc6d83aadcb833ac4cac14994c0b51f725c4573fd179fe6b7e4","tlsh":"a63167f9126191344573b2a46f1bdd67d63bb20354c9fec4f24c43731f129285d676a8"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-r-1.0.0.tgz","hashes":{"sha1":"2eb389e15590d9cf0d6105672207e742f1cb958e","sha512_sri":"sha512-KVDJo8qWMiZcAI+Ggij918ya7M5SzyAw0nkkEJby6RDCMJUA7tL/XH9emNf9YK1tLex8G0WyEPmDV5DVACe5SQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-r/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017396","import_time":"2026-08-12T12:24:09.455938425Z","modified_time":"2026-08-12T12:15:45Z","sha256":"be4bb7a1bd57477bf3cbbb1ccc9b76a2ed8b96a8117e0a4cad882b76404c86fb","source":"amazon-inspector","versions":["1.0.0"]}]}}
