It loads https, path, os, fs, child_process, and crypto; assembles a 4-octet host string via repeated.concat calls to hide the destination; issues an https GET; pipes the response through crypto.createDecipheriv (AES) with a sha256-derived key; writes the decrypted bytes to a file under os.tmpdir(); and executes that file via child_process with windowsHide and cwd set to the user's home directory. The package's declared purpose ('array-node-utils') has no relationship to the shipped code — the module contains no array-handling logic, only the fetch-decrypt-exec chain.\n","affected":[{"package":{"ecosystem":"npm","name":"array-node-utils"},"versions":["1.0.9"],"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":"index.js","sha256":"3a96c07468a2adea3fab5cdfdee801fdb557382a128b0e62b34f013400e5266d","tlsh":"ceb2868d3fd2f0a04237b0f76a1b6895e13aac9cb2cc9409f7a5f058fd58354d165b68"}],"package_integrity":[{"filename":"array-node-utils-1.0.9.tgz","hashes":{"sha1":"3cddce7b3696de276984d15af3ee4a04411beb55","sha512_sri":"sha512-MJ+LPfgCxLWINtm247TrBYK4OHg3rgbRgJrt1amYQsOR7CMzeGjMpLo3VhIhJtBTiK4TkJIP9XUXlGhbPoZxGg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/array-node-utils/v/1.0.9"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-010934","import_time":"2026-07-28T14:19:59.909107928Z","modified_time":"2026-07-28T13:38:38Z","sha256":"c0dbd4ffa55ee3a0972b3e5e3fef599244049244d9f996a9d8b809a3a3a53e1a","source":"amazon-inspector","versions":["1.0.9"]}]}}
