The fetched bytes are written to a hidden temp path of the form.cache_<rand>/dotnet_diag_<rand>.exe, chmod 0755 on POSIX, and spawned detached via /bin/sh -c on POSIX or cmd on Windows. There is no hash or signature verification, the destination hosts are obfuscated by string-split concatenation, and lib/telemetry.js exhibits the same reconstruct-fetch-write-chmod-spawn pattern with require(\"child_\" + \"process\"). The package is presented as 'telemetry', but the code path is an unsigned unpinned remote-code loader that executes attacker-controlled bytes on any machine that installs or requires the package.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-mobile-bnpl-navigation"},"versions":["35.3.2"],"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":"_bootstrap.js","sha256":"c6f39c2492b8cc60d87010e71070d82f64574f76177c356a4ec83fb2a183fdb3","tlsh":"9aa1b66a06a670188f70ebe4c71b8416f65bf6633680c284f79c65945f7252883b3efc"}],"package_integrity":[{"filename":"bnpl-blocks-mobile-bnpl-navigation-35.3.2.tgz","hashes":{"sha1":"404350d69cc7d9b72607a28a68b17a7749fbde0e","sha512_sri":"sha512-elJv2okL/DVceAuR5OTRO7Yp+NkJSHP/iWvf0Hnn+Ylbtazde0ayPi9zBsOB1GKJoYP3fzaCtcTRgYtmVSHYbw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-mobile-bnpl-navigation/v/35.3.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015383","import_time":"2026-08-05T15:19:48.411825191Z","modified_time":"2026-08-05T14:38:40Z","sha256":"295c0eb6e0491ca81198ae9cbeb921b3658d573f98bd43e82e6bbc0fe953683b","source":"amazon-inspector","versions":["35.3.2"]}]}}
