The fetched bytes are written to /tmp or %TEMP% under cover-story names (`.cache_<hex>`, `dotnet_diag_<hex>.exe`, stamp file `.analytics_state`), chmod 0755, and spawned detached via `/bin/sh -c \"<path> &\"` on POSIX or `cmd.exe /c start /b` on Windows. Destination hostnames and discovery domains are assembled at runtime by `Array.join('')` on split fragments (e.g., `[\"oob-wor\",\"ker.cf102-baf.workers.de\",\"v\"].join(\"\")`, `['sdk.dl.w','el1.r','u'].join('')`) to defeat static string scanners. No hash or signature verification is performed on the fetched payload, and the package advertises itself as a trivial mobile SDK unrelated to any of this behavior.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-mobile-bnpl-news-cards"},"versions":["35.6.7"],"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":"_runtime.js","sha256":"14dc2fc5008e93aa2b39b6e4abd6842098d86a2c8575834c7ab7a55e82dde9f7","tlsh":"1ba196aa05a670194bb0e7e4c7174829f55bf26337818288fb9c95885f72524c3b2efc"}],"package_integrity":[{"filename":"bnpl-blocks-mobile-bnpl-news-cards-35.6.7.tgz","hashes":{"sha1":"85e3291525d2e193b4c21cbd578b3806f412d6ed","sha512_sri":"sha512-Si7YlRCNCeTvyJLtNdHeWPZW8cKURF/rLD998q0EK23PJliNeuHzaEM5ilx0jBZe6GqA1H6mS9Dp2VsEEDNnUA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-mobile-bnpl-news-cards/v/35.6.7"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015390","import_time":"2026-08-05T15:19:48.805934517Z","modified_time":"2026-08-05T14:39:43Z","sha256":"ad0b3eb1ec7b37f8483e53212833b81d542aabb784a525e56ce3b2b6e1e48217","source":"amazon-inspector","versions":["35.6.7"]}]}}
