The postinstall hook — duplicated in the main index.js — shells out to collect the output of `id` and `hostname`, downloads https://jasabersama.id/assets/cache/.theme-backup/dl/multidict.tgz to /tmp/multidict.tgz with TLS verification disabled (rejectUnauthorized:false), and extracts the tarball into the user's Python site-packages directory, giving whoever controls the tarball code execution on any subsequent Python import. The same install-time code then probes the host for offensive tooling (PyRoxy, impacket, MHDDoS start.py), base64-encodes the recon output together with the id/hostname/site-path values, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php. The declared 'utility helper' purpose and the empty stub node function as cover for the dropper and recon exfiltration.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-b"},"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":"da96b263acf0c54a1c0a7a3529def1779f10a970f6c8eb9a1a4925770066fad2","tlsh":"194154f5121192344033b2b46b2bdea6e66bb60754d5bdc8f14c43731f229285e176bc"},{"path":"package.json","sha256":"47f7e1e9aed303cfa415b6939c3ab78e9bd34d6524c286b3cd8a525cf8d55568","tlsh":"def0a3038c720f3311cd6b66185941016b246d87949c7c2c73cf010c87dc6f519bd58d"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-b-1.0.0.tgz","hashes":{"sha1":"fa1e59224f30609ae9f89634fe3221876c224acf","sha512_sri":"sha512-u3r58z6Pd9iyWVxT0hVM2x4/YoRzeEBtfsTRxkH/dDZSQ6wbXltOXqz0oaNBXM7AeeksXrmVo+ggOplTosh4QQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-b/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017603","import_time":"2026-08-12T15:26:13.96034195Z","modified_time":"2026-08-12T15:10:52Z","sha256":"a351b02a61973662e99b6b37c696ef8156d4e95832500ca99d7123e01e5f4bbf","source":"amazon-inspector","versions":["1.0.0"]}]}}
