A sibling file extension.js (126KB) uses the same JSFuck encoding, indicating a multi-stage opaque payload. The package has no description, no author, and no dependencies, and ships no readable source — the JSFuck encoding is exclusively an obfuscation technique used to hide executable code from scanners and reviewers. Installing this package causes automatic execution of the opaque payload on the installer's machine during `npm install`.\n","affected":[{"package":{"ecosystem":"npm","name":"catwrestlinghuman"},"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":"index.js","sha256":"d6451b7f8e22341976a24eb4fc2d387909ee0f8ca29559b04648489491c8742f","tlsh":"c4b32e0e0013b795f697ebdc3da87d9e1b695fdb6ab0da1cb609b2924f1dfb09084011"},{"path":"extension.js","sha256":"2c2cd3c56ba604d42003b09a80efdaa90cf93c2f26d5b53bd859cfea74ae3bae","tlsh":"48c32e0e0013b795f697ebdc3db87d9e1a696fca69b0da1cb609b2925f1dfb0d084011"}],"package_integrity":[{"filename":"catwrestlinghuman-1.0.0.tgz","hashes":{"sha1":"743d93b78b0aded70e54005ed9a9dae4c69a99ca","sha512_sri":"sha512-6gAXz8oqf8wOTyX/DeZGrgOTihU7WpFbjpjHifqtHA3hPr6OPJrrpBxhkv5PQGFLAPHnOsUm+idCoCmAsa+BGg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/catwrestlinghuman/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-020227","import_time":"2026-09-21T03:46:37.750285258Z","modified_time":"2026-09-21T03:30:19Z","sha256":"6c4045339387526c5db90832687d1691c2caddba3b9cb05006022704bf094653","source":"amazon-inspector","versions":["1.0.0"]}]}}
