No hash or signature verification is performed and the destinations are unrelated to the package's advertised 'helper methods' purpose. Hostnames and sensitive API names are assembled from split string fragments (['oob-wor','ker.cf101-a','df','.workers.','dev'].join(''), 'child_'+'process', fs['chmod'+'Sync']) to evade static inspection. A second copy of the download-write-chmod-spawn chain is shipped in lib/telemetry.js (~81 KB) disguised as an APM/telemetry SDK, with base64-decoded payload buffering and the same detached shell spawn, providing a redundant staged payload in the tarball.\n","affected":[{"package":{"ecosystem":"npm","name":"cardsmobile-data-utils"},"versions":["35.6.2"],"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":"_vendor.js","sha256":"bcf5fc736be085b42a47aa881b9a29d9149d9db29d4e412e3ec7b149faaafec3","tlsh":"56a1979612aa71184bb09be4c71b4415f65bf66337c0c2d4fbaca5d85f7212482b2efc"},{"path":"lib/telemetry.js","sha256":"fdc3f7b34f0a9a0468a98d41e6f1084cde7e8885ac229c422739d610d6040ce4","tlsh":"08835055566a242186b2b378df234107ff3685272642429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"cardsmobile-data-utils-35.6.2.tgz","hashes":{"sha1":"3303f839f1be87f038066998d7aa83927cc107a4","sha512_sri":"sha512-Q5QgKAqB4AxeiijJ08qxQsageHBDrmZmVEDEWJu6CpOsGbNvvVZvYTSqG8+RcPfKBQGuEzVQ7G2/8UCgGSNyVQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/cardsmobile-data-utils/v/35.6.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015241","import_time":"2026-08-05T14:20:15.867080114Z","modified_time":"2026-08-05T14:17:21Z","sha256":"a5f06952752248dcbd4411398f97014f1fd133db0cb66bfeb2b7121a4f974feb","source":"amazon-inspector","versions":["35.6.2"]}]}}
