The same code path is present in index.js, which is declared as the package `main`, so require()ing the module re-triggers the dropper even when installation runs with --ignore-scripts. Both files also collect installer host identity (`id`, `hostname`, process listing, /proc/loadavg), base64-encode the data, and send it via HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized: false). The package presents itself as an n8n utility node but contains no such functionality; its only behavior is host reconnaissance exfiltration and using the installer's machine as a DDoS bot against a third-party target.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-s"},"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":"index.js","sha256":"2d4a88d7ac61db1d7d9afad967897f9a65e2e2556019e3711f7749d0471ba641","tlsh":"174183e33ab89434d5b32090a8a6ee42a627b10b5586fdd8f04dd6b20f6b03827914f4"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-s-1.0.0.tgz","hashes":{"sha1":"b4c88dbc58bb5550d768712177ba021630088222","sha512_sri":"sha512-PSssE+YnRr4BT/UmB+jsDwT8iqVTTTcmgdQDUZzR4LgBB7fbDi0wMySKrm0XHObAnJN++hG1U8AOb17rBl7lAg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-s/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017582","import_time":"2026-08-12T15:26:11.714642761Z","modified_time":"2026-08-12T15:07:57Z","sha256":"2955ed4843fe66495bbe53420b28e91530f48facae3aea0a9c3719676c30c0a5","source":"amazon-inspector","versions":["1.0.0"]}]}}
