On npm install the postinstall script collects host identity (`id`, hostname) via callback.js, base64-encodes the result, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized:false). The same postinstall path installs the impacket network-attack library via `pip install --break-system-packages`, probes PyRoxy, and attempts to execute /tmp/mhddos/start.py (MHDDoS). Installing this package auto-runs reconnaissance, exfiltrates installer host identifiers to a hardcoded third-party endpoint, and stages offensive DDoS/network-attack tooling on the installer's machine.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/n8n-nodes-utils-helper-v"},"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":"4e3b8c5eb59ae45053e07d90e2e09f4a5d16670876330c8dd3f152ccc3527bd4","tlsh":"5521f0f51201e1348572f0a4ba6bde56f86ff70310dab5c8f10e86b34b125596b135a8"},{"path":"package.json","sha256":"3e89ebb860703c85d6f294b1157471570f77215fcafbe123f33950b3ba7c4bbd","tlsh":"1af0e5128db24f3321cd6b66589e8141aa246e9b949c7c2873cf010d87986b52abe699"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-v-1.0.0.tgz","hashes":{"sha1":"a2b826616f6a5f7f2ac5553f8833763ef82d9136","sha512_sri":"sha512-alKk+yEoetbMsLJ2N26GF3pejTbX9V35Uo03K9mkWrlTYF1hVDyJENYnYl22vfVaawkJmy/q48jJSn2+Q+FLCA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-v/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017391","import_time":"2026-08-12T12:24:08.926624149Z","modified_time":"2026-08-12T12:15:05Z","sha256":"9923595138c727382a8b1e870530f6d55ded8a052ee374569ad8b87b1560c07f","source":"amazon-inspector","versions":["1.0.0"]}]}}
