Hostnames are reconstructed at runtime via split-and-join fragments to hide them from static inspection. The downloaded bytes are written to a disguised temp path (.cache_<rand> / dotnet_diag_<rand>.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd. No hash or signature verification is performed and the destinations bear no relation to any declared publisher. A second, structurally identical dropper is bundled as lib/telemetry.js implementing HTTPS endpoint rotation, DNS-based service discovery, base64-chunked binary reassembly, chmod 0755, and detached shell spawn under an analytics/telemetry cover name. Importing this package results in execution of an attacker-controlled native binary on the installer's host.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-desktop-bnpl-card-gallery"},"versions":["35.1.6"],"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":"_ext.js","sha256":"d3176e7521e3ed76a3e2ac0d17e957ef72e0958c3e11acd555e665566f65aada","tlsh":"39a1a79a166a301d4bb0ebe4c7175419f65af6633380c2a4f79ca5941fb712483b1efc"},{"path":"lib/telemetry.js","sha256":"1834de8e00488ba37efee3e3decb0a294e0fc8f523fb8053d8443e9f49418321","tlsh":"c5835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"bnpl-blocks-desktop-bnpl-card-gallery-35.1.6.tgz","hashes":{"sha1":"f83e2b0601c69dd2b23a355a96a770a473004bb0","sha512_sri":"sha512-B83kM7O1U2DV2t3NYCO43RiOk7nZRMCNR9x05WUs+xfosdTQQiKwfwWFH5jL9LHpAVNPS/RftHoaq7AZ6FkEZA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-desktop-bnpl-card-gallery/v/35.1.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015465","import_time":"2026-08-05T15:19:52.959933954Z","modified_time":"2026-08-05T14:50:51Z","sha256":"d7d63ed62a217e197558ea54716acadb75a5a4c6a7b57545b5ec8c8d86abb656","source":"amazon-inspector","versions":["35.1.6"]}]}}
