The fetched bytes are written to a temp directory under a disguised name (dotnet_diag_<hex>.exe on Windows,.cache_<hex> on Unix), chmod 0755 is applied on Unix, and the file is spawned detached via cmd.exe /c start /b or /bin/sh -c. Destination hosts are split into fragments and reassembled to evade string scanning. An execution-stamp file suppresses re-running. The package advertises itself as a native bridge but ships no native source, so the only effect of importing it is dropping and executing attacker-controlled code on the installer's host.\n","affected":[{"package":{"name":"bnpl-blocks-mobile-bnpl-link-group","ecosystem":"npm","purl":"pkg:npm/bnpl-blocks-mobile-bnpl-link-group"},"versions":["35.2.3"],"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":"_support.js","sha256":"8d87a94fba62fd26344b998afdcf4d6ac88aca8f2758512fc7f17dd7a005c095","tlsh":"cfa1ba9a16a670184bb097f4c7274416f65be6a333c08194fb9ca5981f7752483b2efc"}],"package_integrity":[{"filename":"bnpl-blocks-mobile-bnpl-link-group-35.2.3.tgz","hashes":{"sha1":"9e8c1fc4362105a3185c3e95e17ac5784ebc0cb4","sha512_sri":"sha512-fGcGi6RVsf6k9v3yBj3jT8ZkXpUX4PmuZOVXmciYNoUXifF2aI8zlscgV831MQMZo3xk1np8HRtDdcTUmPAUuw=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/bnpl-blocks-mobile-bnpl-link-group/MAL-2026-12996.json"}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-mobile-bnpl-link-group/v/35.2.3"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015385","import_time":"2026-08-05T15:19:48.52179878Z","modified_time":"2026-08-05T14:38:57Z","sha256":"b6203d02c8bfb651950b571dd342ff82e154a3c3867af751a7fb1facdb5bd0f5","source":"amazon-inspector","versions":["35.2.3"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
