Hostnames and resolver domains are assembled at runtime from split-string fragments to evade static analysis. The downloaded bytes are written to a temporary path under a deceptive name (`.cache_<hex>` on Unix, `dotnet_diag_<hex>.exe` on Windows), chmodded 0755, and detach-spawned via `/bin/sh -c \"<path> &\"` or `cmd.exe /c start`. Cover-story environment variables (`DISABLE_TELEMETRY`, `ANALYTICS_OPT_OUT`) and cache/diagnostic naming disguise the dropper as telemetry. Reachable on first `require()` of the package; no user opt-in required.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-independent-bnpl-breadcrumbs"},"versions":["35.6.6"],"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":"setup.js","sha256":"c1000d80651a76b1a21490b59d8850ba73697ebd6d1f4cc1e332bc3029cf17c6","tlsh":"4cb1a796176a70188b70dbf5c71b4415f657f66337808188f79c59981fb212483b2efc"}],"package_integrity":[{"filename":"bnpl-blocks-independent-bnpl-breadcrumbs-35.6.6.tgz","hashes":{"sha1":"8a4964886b6e41c196bd95932321f11eda0d09f9","sha512_sri":"sha512-oPfuM71oejH0pVozzaJbDT9KdK5THNwUNlM9w5ObVAn6lzY1JdEyndGR1Q4csb7N8gZf/QMYhW+sAJ8LsdTfzA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-independent-bnpl-breadcrumbs/v/35.6.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015432","import_time":"2026-08-05T15:19:51.106875264Z","modified_time":"2026-08-05T14:45:50Z","sha256":"f1d442b520a1779845bf9dc5d8a0cd822606ec46e0a01850143b93e14658cfe9","source":"amazon-inspector","versions":["35.6.6"]}]}}
