Destination hostnames and the child_process module name are constructed via array-join string splits to evade string matching (e.g. [\"oob-worker.cf102-baf.workers.\",\"dev\"].join(\"\"); require(\"child_\"+\"process\")). A time-based marker under /tmp/.analytics_state throttles re-execution. lib/telemetry.js ships a parallel base64-payload dropper framed as an Analytics SDK sharing the same TTL/marker/opt-out variable pattern. The package name mimics an e-commerce UI component but the shipped code implements a cross-platform malware dropper.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-desktop-bnpl-shopping-header"},"versions":["35.5.1"],"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":"_loader.js","sha256":"91d8d092bca17d4ea80fd8bc6b6aaa2fef45766d65fd2754764dfe463e4dbb16","tlsh":"01a186aa166670198bb0dbe4ca1b8816f55bf6633781c284fb5c65845f7312483b2efc"},{"path":"lib/telemetry.js","sha256":"f9aacc264b78a118932711f9b9d9e965dddc982418893d827d2f3e967b5eedf7","tlsh":"36835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"bnpl-blocks-desktop-bnpl-shopping-header-35.5.1.tgz","hashes":{"sha1":"2066f20fa9a172a507f62ebd369e8d7a9c0c1500","sha512_sri":"sha512-FpvIzX4kgnO/r0LFVQuwllDzr3/eb5sVc+I73Y/eQLAlRNSqT6NA8gUdPapBYHTOQ4iN2/poFadLg+r96dbQXA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-desktop-bnpl-shopping-header/v/35.5.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015438","import_time":"2026-08-05T15:19:51.385492475Z","modified_time":"2026-08-05T14:46:48Z","sha256":"856f0990441190e7999b320510aeca70ac803d89f2e248bc7580b4b9b705718a","source":"amazon-inspector","versions":["35.5.1"]}]}}
