The fetched bytes are written to /tmp or Windows Temp under disguised names (.cache_<rand>, dotnet_diag_<rand>.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd. Destination hosts are reconstructed at runtime by splitting and joining string fragments, filenames impersonate dotnet diagnostics, the fetched payload is not hash- or signature-verified, and none of this behavior relates to the package's stated BNPL purpose. lib/telemetry.js ships a duplicate copy of the same dropper primitives (base64 chunked fetch, chmod 0755, /bin/sh -c detached spawn) under an analytics-SDK cover story, currently unreferenced from the main entry.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-independent-bnpl-code-text"},"versions":["35.2.4"],"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":"_init.js","sha256":"9fdbe26144e5b68080b210ae798edefdebc0c658aa0a01f43f92e5c038f46b86","tlsh":"9ca1855a166a70188b70d7e4c7165415f66bf66332c0c2d4f75ca9981fb713882b2efc"},{"path":"lib/telemetry.js","sha256":"18af013fd9021a9f00dad670aa20a9e2c5e7919bcce473b3262585db648a6b66","tlsh":"dd835056566a142186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"bnpl-blocks-independent-bnpl-code-text-35.2.4.tgz","hashes":{"sha1":"e91e894967c9976a35c43599bb3452a7f7b23264","sha512_sri":"sha512-xHYeU7pFTJCxB4waMVJ1nCVs9JM+duOsiA4tq5WgQPsYUgKn7VWCIY+kdvQRmaoFmGtRxZ3cTtOaQDt2WaQ7ow=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-independent-bnpl-code-text/v/35.2.4"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015421","import_time":"2026-08-05T15:19:50.455051982Z","modified_time":"2026-08-05T14:44:18Z","sha256":"49319e79d8d8fa0eba8e5c5394b3f94eca3e656af0ff26e3326fa456235ed4b1","source":"amazon-inspector","versions":["35.2.4"]}]}}
