The combination of automatic install-time execution, host fingerprinting, filesystem reads, and outbound POSTs is the canonical install-time exfiltration shape. Installing this package on a developer machine or CI runner will run the reconnaissance and exfiltration code without user interaction.\n","affected":[{"package":{"ecosystem":"npm","name":"data-utils-bcf2"},"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":"package.json","sha256":"561e6c852bc499eb123d918890a06d3da33f87965198b84c9ff50c3061499d35","tlsh":"ece068289c20393339c02ae80c669297f7308f1b30143d2d92b72829429bb7ab47b24d"},{"path":"run.js","sha256":"23c111f3ecd1f37bea0f0fb0b51d6bdac267d3adcfdd52d972f72cda6f82ac42","tlsh":"c382e7b219b7461479a3e6ade66fa4005033f1177a51eda0f28c73510fcf668d1b2af8"}],"package_integrity":[{"filename":"data-utils-bcf2-1.0.0.tgz","hashes":{"sha1":"c3a92d7f44c7c0064b0cdd531e84f88bfb7c6e07","sha512_sri":"sha512-cockDOMoPNHjz28QODHA21n/5DBJ5ytblFscjWFzHG53stSLKacUikj+jDjKsQ1Htj39ZU7q0bWRfXrl+SJ5nQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/data-utils-bcf2/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-006960","import_time":"2026-06-18T05:42:04.371373899Z","modified_time":"2026-06-18T03:54:28Z","sha256":"52e6ddf4cbc1a035918a5bd136c865ff526f430db21268d75d3c90fa74196fdf","source":"amazon-inspector","versions":["1.0.0"]}]}}
