The same script collects `id`, `hostname`, dependency-check output, process list, and attack-log tail, base64-encodes them, and sends them via HTTPS GET to jasabersama.id/portfolio-data.php as a beacon. The package's declared main entry index.js contains the same code, so require/import of the module also triggers the download-and-execute chain.\n","modified":"2026-08-12T15:30:13.592986453Z","published":"2026-08-12T15:09:28Z","database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017593","import_time":"2026-08-12T15:26:12.712644561Z","modified_time":"2026-08-12T15:09:28Z","sha256":"3f484be79b89b443e145029a177ed84e3d55653a6ab1d0f62cec1df2eff70c44","source":"amazon-inspector","versions":["1.0.0"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-i/v/1.0.0"}],"affected":[{"package":{"name":"@years19/n8n-nodes-utils-helper-i","ecosystem":"npm","purl":"pkg:npm/%40years19/n8n-nodes-utils-helper-i"},"versions":["1.0.0"],"database_specific":{"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"package_integrity":[{"hashes":{"sha1":"ea19c71b3caa90629c888ac106987d1b94703371","sha512_sri":"sha512-MinB85c/+ryjrF351JOHro4U9o0Zj3a74g6Lx4mqFZOx0Vfhb8vqqPkjccWfWUVu9GeC+sxKvcNnAE7+kJQD+Q=="},"filename":"n8n-nodes-utils-helper-i-1.0.0.tgz"}],"evidence_files":[{"sha256":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78","path":"callback.js"},{"sha256":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78","path":"index.js"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@years19/n8n-nodes-utils-helper-i/MAL-2026-13892.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
