The file uses a hardcoded hostname target, executes shell commands to gather system data, and transmits it over HTTP without any relation to the package's advertised data-transformation purpose. The package name mimics the n8n community-node naming convention, providing a lure for users seeking legitimate n8n utilities. Installing the package on default settings triggers immediate host reconnaissance and outbound exfiltration to an attacker-controlled destination.\n","affected":[{"package":{"ecosystem":"npm","name":"n8n-nodes-data-transformer-utils"},"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":"postinstall.js","sha256":"1c63ac3ce59025a1cefe6fbc70eb1b38138aa589725963372e02db63d1e0b5e7","tlsh":"f1c183c5a9f59c317ebfe469b16b901f2923a0072645fc04b35959210f0fa5ce2ba3f9"}],"package_integrity":[{"filename":"n8n-nodes-data-transformer-utils-1.0.0.tgz","hashes":{"sha1":"a3b8436b5831959d5738d8dea19f83176749c217","sha512_sri":"sha512-X/S1N/kJhO1DWeAEAlDqYSR4sHwkq+G0lgomxb8ijLQkcETAdhncW2nRbh+UxDBaRB7gzAPMV40oYVxax0Y/Cw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/n8n-nodes-data-transformer-utils/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-020315","import_time":"2026-09-22T22:16:11.740888974Z","modified_time":"2026-09-22T21:52:37Z","sha256":"77b996187dc49e5591ddf3cef428be3a9309e7f5bab48bd4698aed2be0c3dfb0","source":"amazon-inspector","versions":["1.0.0"]}]}}
