The script fires automatically on npm install, confirming installation on the installer's machine and providing a channel to exfiltrate host or environment values via the expanded shell expression. The shipped index.js is an empty stub, so the manifest's postinstall beacon is the package's entire effect. The destination is an anonymous ngrok-free.app tunnel with no relationship to any legitimate publisher, consistent with a dependency-confusion or install-confirmation probe.\n","affected":[{"package":{"ecosystem":"npm","name":"black-spindle-2"},"versions":["301.0.0","100.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"package.json","sha256":"23ed0ca25321dfb43a5d9ced2e644ec77ddcd0396c531171048b4f0d1a8c0a66","tlsh":"7ac0226249a1066330a087bee4f686037a020a2f21b04a8db0b360180a510371b09b2a"}],"package_integrity":[{"filename":"black-spindle-2-301.0.0.tgz","hashes":{"sha1":"d760479febfaa0c100b132588019f47f8bb0ca49","sha512_sri":"sha512-6HOhR1bBUj0FmPR7tBnZHN7oontvG1KasNxMP3ryP/8pzdRTRvV94kvKktiwdQ/YO558WcZV3xrD1fJPwVPbdw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/black-spindle-2/v/301.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/black-spindle-2/v/100.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-022416","import_time":"2026-10-29T15:13:34.018067481Z","modified_time":"2026-10-29T14:59:21Z","sha256":"433228fbed18f3104fed4cd1bce59bc5a76b8ea061d18c8fc9516c92b6b26e90","source":"amazon-inspector","versions":["301.0.0"]},{"id":"IN-MAL-2026-022417","import_time":"2026-10-29T15:13:34.16295529Z","modified_time":"2026-10-29T14:59:29Z","sha256":"f973afbbc02414b7152e990c158f7ede82cfc71a14c99ece0b714b57e50b2a55","source":"amazon-inspector","versions":["100.0.0"]}]}}
