The downloaded bytes are written to a hidden path under /tmp or %TEMP% disguised as 'analytics_state'/'dotnet_diag', chmod'd 0755 on POSIX, and spawned detached via /bin/sh -c or cmd.exe. There is no pinning, no signature check, no publisher relationship between the destination hosts and the package's declared purpose (a 'BNPL notification' library). Execution is gated by a stamp file for rate-limiting and by opt-out environment variables.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-desktop-bnpl-notification"},"versions":["35.8.9"],"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":"_runtime.js","sha256":"81813e198041462c421e8b32eada6df20d1e1af8db0707500fe08ec3ed381d41","tlsh":"eaa197aa156670184bb0dbe4c6075815f65bf6a373c09294f79c659c0ff212483b2efc"}],"package_integrity":[{"filename":"bnpl-blocks-desktop-bnpl-notification-35.8.9.tgz","hashes":{"sha1":"d437c57ee14da83706d57deb41afb4aeb6da9779","sha512_sri":"sha512-/dxbo/aPTTDkRWOIhiSw5wOu5ABRITAG4xKszshXKS1lHOSZ59XTg5OS5aZQjsCHlM1oo8giVQk6DtaupM48dQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-desktop-bnpl-notification/v/35.8.9"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015447","import_time":"2026-08-05T15:19:52.001232912Z","modified_time":"2026-08-05T14:48:08Z","sha256":"0de35e4aa0a895b91234b28bdbe2413b0c6d855758348954f2a438185165de00","source":"amazon-inspector","versions":["35.8.9"]}]}}
