In parallel, it collects the output of `id` and `hostname` plus install-progress markers, base64-encodes them, and sends them as a query-string parameter to https://jasabersama.id/portfolio-data.php with a fixed key `S7k9xQ2mZj`. The payload URL is staged under a `.theme-backup/dl/` cover-story path on a domain unrelated to the package's declared purpose, and the package's n8n node file is a stub — the sole functional code is the malicious postinstall. The name mimics legitimate n8n community node packages.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/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":"386ff7324fc13471de7a3cb987a733b8a498411ea72de40bfbe8806b330def50","tlsh":"3941b9b51261a638803362687f2bdd66e23bf10754c5bac8fa4d43b35f019345d2a768"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-s-1.0.0.tgz","hashes":{"sha1":"cc4f38b4c09a290475d1597338d33c41aa0dd5cb","sha512_sri":"sha512-gfPwZdSXxYHgpmv8kh+k5+nPQF/ssiL7csp6LJ/cCH4K7UDSYlYgRfRcFNoxXfUSBlDzGiijrrHIzNUys2k5BQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/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-2026-017394","import_time":"2026-08-12T12:24:09.251224206Z","modified_time":"2026-08-12T12:15:28Z","sha256":"791cd15471cd2592323fdd5d9b58f79903e29a77b73384d0fd8b1bc7b4b43342","source":"amazon-inspector","versions":["1.0.0"]}]}}
