The postinstall lifecycle script collects installer host identifiers (hostname, platform, arch, node version, package name, npm lifecycle event, timestamp) and POSTs them as JSON to the hardcoded endpoint https://ucjtw03t.instances.poc.jchunt.top/magika-js. The beacon fires automatically on npm install with no opt-in and no documented purpose served by the transmission, sending installer machine data to a non-publisher domain. A source.txt pointer to github.com/google/magika reinforces the impersonation of Google's project.\n","affected":[{"package":{"ecosystem":"npm","name":"magika-js"},"versions":["4.1.1"],"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":"2195c3150cd65f4c27a4e9c5ec774d81bc7e93c3b98f06e4d04104ecbfeb1f91","tlsh":"550123c0d2bd9f321bf4578060d1a90682bbd2637b0a607a67c802353fcd5f9007319d"},{"path":"source.txt","sha256":"88db4caf996b491b0b2a4cc64942f7116fe51ef054d84c861b6568e3de350dc9","tlsh":"05a022ffb00882a00e202e8e38c8820c83200220f8a3c3eee0220002b00008208c3aa2"}],"package_integrity":[{"filename":"magika-js-4.1.1.tgz","hashes":{"sha1":"cee49483791181522cb29b7ecb75337ac569c118","sha512_sri":"sha512-eIBrJYZfvwetcFyW1fKyCDwzf9jRB2wpX9iH8X7jhZM9EihxEWRwesyQ6TBVvEi/40HPCZ2SXtJxOwsibRBRMw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/magika-js/v/4.1.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018345","import_time":"2026-08-19T04:18:13.687035721Z","modified_time":"2026-08-19T03:56:20Z","sha256":"41cd28e41bc842fd046a2bff254f450edd0b6d2d15d961fe768cf5e9ebfa197f","source":"amazon-inspector","versions":["4.1.1"]}]}}
