The real behavior is in callback.js (invoked via scripts.postinstall and byte-identical to the package's main index.js): it shells out to gather host reconnaissance (id, hostname, git and node versions, n8n install paths, contents of ~/.n8n), base64-encodes the output, and transmits it over HTTPS GET to a hardcoded endpoint at https://jasabersama.id/portfolio-data.php with a fixed key parameter and TLS certificate verification disabled (rejectUnauthorized:false). The URL's `c=` parameter smuggles a shell pipeline (`echo <base64> | base64 -d >> /tmp/n8n_rce_result.txt`) indicative of C2-style tasking. The exfil fires automatically on `npm install` and again on any `require()` of the package.\n","affected":[{"package":{"ecosystem":"npm","name":"@years20/n8n-nodes-utils-helper-h"},"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":"5a13680f40c94f07baff06a4dfc97bb192a7a8bedbb20bfd11f21ec6200f9f7b","tlsh":"642114f96350d234546370945a7aee46ed6bfa0b10d9efc4f10e86734b22ce86b521b8"},{"path":"package.json","sha256":"81c200a495884be780a26be4773a9bcef0532b4b1afec19ebb6b4587532669ba","tlsh":"6cf0ab038c730f3321cd6b6b189a8141aa246e9b949c7c2c73cf010c87dc6f52abe68d"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-h-1.0.0.tgz","hashes":{"sha1":"2b5b4e762937be7847661dab3a5fd524c24eebb7","sha512_sri":"sha512-8hkWfbDK1dxpWcMfzBrMldQOnwyI2ckUlIMheuwiuZkuBKqFkRglahkQCritGH7FFVPWC2v2x7O+Z1YfNbq49A=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years20/n8n-nodes-utils-helper-h/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017610","import_time":"2026-08-12T15:53:00.614545985Z","modified_time":"2026-08-12T15:39:56Z","sha256":"96661ee04dc82c36bfa5683fc33f6d7a29d10d1e1bc21ece83ea4189dcf33ef3","source":"amazon-inspector","versions":["1.0.0"]}]}}
