The fetched bytes are written to /var/tmp/.cache_\u003crnd\u003e on POSIX or %TEMP%\\dotnet_diag_\u003crnd\u003e.exe on Windows, chmod 0755, and spawned detached via /bin/sh -c or cmd. A stamp file named.analytics_state and the dotnet_diag_* filename disguise are used to blend into normal system activity. Any require()/import of the package triggers download-and-execute of opaque attacker-controlled code on the installer's machine.\n","modified":"2026-08-07T13:20:16.563392317Z","published":"2026-08-07T12:32:37Z","database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","versions":["35.8.2"],"id":"IN-MAL-2026-017023","import_time":"2026-08-07T12:51:22.602583377Z","modified_time":"2026-08-07T12:32:37Z","sha256":"bcd2fbb910548df40180cd1e71ae6234dddbd8c60b871933d9012bab9f0742bb"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-atom-bnpl-faq-item/v/35.8.2"}],"affected":[{"package":{"name":"bnpl-blocks-atom-bnpl-faq-item","ecosystem":"npm","purl":"pkg:npm/bnpl-blocks-atom-bnpl-faq-item"},"versions":["35.8.2"],"database_specific":{"indicators":{"evidence_files":[{"path":"_ext.js","sha256":"7d120bd6af322356bfd075f029d297fd34f36a160e9806773882247a2f9206d2","tlsh":"58a1b69a166a700987b0d7e4c6274416f65be66337c0d5d8fb9c65981f730248372efc"}],"package_integrity":[{"filename":"bnpl-blocks-atom-bnpl-faq-item-35.8.2.tgz","hashes":{"sha1":"a10c0bb6510dd7db7793f662abb1323fc1578d43","sha512_sri":"sha512-JZ4VUSkTKO2b63Ptf6nBw0rPzMa5oioTbLWFVZ3jnCy8Yy8A0WyYzHRW5jPWcfo5sxqjBC3RsRgC/PmtbYoVQA=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/bnpl-blocks-atom-bnpl-faq-item/MAL-2026-13528.json","cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
