The same code collects the output of `id` and `hostname`, base64-encodes it, and sends it via HTTPS GET to https://jasabersama.id/portfolio-data.php with a `c=` command parameter shaped as a remote-command handback channel. Because index.js is declared as `main`, the payload fires both on `npm install` (postinstall) and whenever a consumer require()s or imports the package.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-l"},"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":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78"},{"path":"index.js","sha256":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-l-1.0.0.tgz","hashes":{"sha1":"41ee1783d6b1ffa5a2b76c41ea1af0342370c0d2","sha512_sri":"sha512-Xr6U60wq0rndp2BiW9vC6VymO5mHiusFMePrXQW143EwmSXsDfCp1eRe3Yb1Z8up1QbMquRgAP1R31zZh5fzIg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-l/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017591","import_time":"2026-08-12T15:26:12.488077579Z","modified_time":"2026-08-12T15:09:13Z","sha256":"bead18d11dfd3ec4bd14bfa0e950bfa53a8bd30ed66225a3dec3b47b81e5aa16","source":"amazon-inspector","versions":["1.0.0"]}]}}
