The fetched bytes are written to /var/tmp or %TEMP% under disguised names (.cache_<rnd>, dotnet_diag_<rnd>.exe), chmod 0755 is applied, and the file is spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start /b. A second, equivalent dropper ships in lib/telemetry.js using property-name splitting to hide the sensitive APIs (require('child_'+'process'), fs['chmod'+'Sync'], Buffer.from(chunks,'base64'), cp.spawn('/bin/sh',['-c', filePath+' &'])). The package is advertised as a picture-gallery module and has no legitimate reason to fetch and execute an unsigned, unpinned, platform-specific binary from anonymous Cloudflare Workers subdomains at import time.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-independent-bnpl-picture-gallery"},"versions":["35.2.9"],"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":"_platform.js","sha256":"74bbe0f8cec4f87ac5951ad5b317d5be5a64db8bb83328ec0a950881f7f2a26a","tlsh":"22b1855a16a5b0188fb0abe0c61b4816f66bf653368181c4f79c59985f73524c3b2efc"},{"path":"lib/telemetry.js","sha256":"fe915c7894ab931b4e16e085e2eec6ece7174de25478b71700ccba1eee9ba3b9","tlsh":"cd835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"bnpl-blocks-independent-bnpl-picture-gallery-35.2.9.tgz","hashes":{"sha1":"b75537e6fb15554a2deab15382b3dbeefce6aed3","sha512_sri":"sha512-qDHrIbwNqigfPkWe9C1lw56OKAxhVsSOO5cokdDe/9QRh5EMuDy3qu/R6vsSzGzO9IMKfShDswZMI+J/gQmWAA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-independent-bnpl-picture-gallery/v/35.2.9"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015406","import_time":"2026-08-05T15:19:49.662835427Z","modified_time":"2026-08-05T14:42:08Z","sha256":"ac08a6b45c3e5bf1e25af236946e35b0329112aa715242ba326ee5b1c5f7621d","source":"amazon-inspector","versions":["35.2.9"]}]}}
