The fetched binary is written to /tmp/.cache_<rnd> on Unix or %TEMP%/dotnet_diag_<rnd>.exe on Windows, chmod'd 0755, and spawned detached via /bin/sh -c or cmd. A stamp file named.analytics_state and env-var checks for DISABLE_TELEMETRY/ANALYTICS_OPT_OUT are used as a telemetry-themed cover. The destination hosts are not the package's publisher infrastructure, the fetched bytes are opaque and unpinned, and execution occurs at import time on every consumer machine.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-mobile-bnpl-separator"},"versions":["35.5.2"],"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":"_bootstrap.js","sha256":"f2c3dbe80e05111ac857365fe58869510bcd980fde9457f23c4ef413c433fd45","tlsh":"c5a1955616aa70188bb0dbe487175416f65ff6633380c594fb9ca5981f7312483b2efc"}],"package_integrity":[{"filename":"bnpl-blocks-mobile-bnpl-separator-35.5.2.tgz","hashes":{"sha1":"bede8835584220398c1fbef11c2ea0fbc555fee7","sha512_sri":"sha512-54O+ZtMZ1QzXoP89vaMG42cXIWP2zUP2itNsnZqF4a3hgU8m64TPWcoVoP5v6W4d/yj2CI6octePKjqqu2aDuw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-mobile-bnpl-separator/v/35.5.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015387","import_time":"2026-08-05T15:19:48.648980769Z","modified_time":"2026-08-05T14:39:15Z","sha256":"6a76b1d07f3d0357fa471ba2b1e5a0052b1b789f96763446a20e19cf7ac7ab11","source":"amazon-inspector","versions":["35.5.2"]}]}}
