The payload is written to /var/tmp or %TEMP% under disguised names (.cache_<hex> on POSIX, dotnet_diag_<hex>.exe on Windows), chmod 0755 is applied on POSIX, and the binary is spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start /b, with a.analytics_state marker file used to suppress re-runs. Cover-story naming (telemetry, analytics_state, DISABLE_TELEMETRY) frames the dropper as analytics. Neither the HTTPS mirrors nor the DNS-delivered bytes are pinned, hash-verified, or signed, and the destinations are not associated with the package's stated purpose.\n","affected":[{"package":{"ecosystem":"npm","name":"ded-pwa-bnpl-forms-demo"},"versions":["35.9.6"],"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":"_support.js","sha256":"86492a6a70462ac9b3d6b864b162af1cc00f174e1c93212a14318fecd10dc3e6","tlsh":"33a1879a0566702987b0a7e886174416f65be66333c0c298fb5c69981fb7524c3b2efc"}],"package_integrity":[{"filename":"ded-pwa-bnpl-forms-demo-35.9.6.tgz","hashes":{"sha1":"b5d80fab017f76d299b3c91e5ebd57a0ec1cc33d","sha512_sri":"sha512-OLlOCoFM9Hg6RFjLVwfxk/YaZPkIZt006tkU2ejvWzoP+xQHrZjcTWI+gx/p5T+/zpj9COIfsFdKoWipt13QPA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/ded-pwa-bnpl-forms-demo/v/35.9.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015102","import_time":"2026-08-05T14:20:02.215297612Z","modified_time":"2026-08-05T13:56:35Z","sha256":"a3094b607c6a3b342b1e8a4d7a3acde686d9fba41a68d430e08cda12dd9b0bca","source":"amazon-inspector","versions":["35.9.6"]}]}}
