Host strings are reassembled from arrays via.join(\"\") to hide them from string scans; execution is gated by a /tmp stamp TTL and skipped when DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK are set; the dropped filenames mimic OS artifacts. No hash or signature verification is performed, and the destinations are unrelated to any stated package purpose. A sibling module lib/telemetry.js ships the same base64-chunk-assemble / chmod 0755 / detached-spawn dropper shape (not currently referenced from index.js in this version but present in the tarball).\n","modified":"2026-08-05T16:50:49.584812484Z","published":"2026-08-05T15:22:05Z","database_specific":{"malicious-packages-origins":[{"versions":["35.1.7"],"id":"IN-MAL-2026-015670","import_time":"2026-08-05T16:13:30.368145809Z","modified_time":"2026-08-05T15:22:05Z","sha256":"a1e1c76ea93bbc42ff9d45e1e876946d87d62dd9470683f34ffd312935b27802","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-boxy-independent-bnpl-documents/v/35.1.7"}],"affected":[{"package":{"name":"dolyame-boxy-independent-bnpl-documents","ecosystem":"npm","purl":"pkg:npm/dolyame-boxy-independent-bnpl-documents"},"versions":["35.1.7"],"database_specific":{"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-boxy-independent-bnpl-documents/MAL-2026-13316.json","indicators":{"evidence_files":[{"path":"_bridge.js","sha256":"e5a6d106f09e3cbe7307d259cda60ae897297ce1c72f9a16b45d0ea0d987f034","tlsh":"2ea1965a12a770188bb097e4871b5416f65be6633781c2c8fbac55881fb612483f2efc"},{"tlsh":"45835055566a242186b2b368df234107ff3685272642429dbafc82dc1fbd72092a5ffc","path":"lib/telemetry.js","sha256":"e9c0320b6880d7b5a0d62ed7181308a1d860964ab0125a11e447ca8ec96afcc0"}],"package_integrity":[{"filename":"dolyame-boxy-independent-bnpl-documents-35.1.7.tgz","hashes":{"sha1":"537bc9e67f4f9dd41df6d5a0cc602576f83d0f19","sha512_sri":"sha512-0tXFJIUyf2+vUjkd15yZSIHGUls8gUK34GqU3+o+Bn0wCbGrh3I1u+gp7GH9URxpxA2zF/e2JA9lEOLAycKalQ=="}}]}}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
