Destination hostnames are string-joined at runtime from substring arrays to defeat static URL scanning. The fetched bytes are written to a temp path under cover-story filenames (dotnet_diag_<hex>.exe on Windows,.cache_<hex> on Unix), chmod 0755'd, and launched detached and unref'd via cmd.exe /c start /b or /bin/sh -c '<path> &'. A second dropper implementation in lib/telemetry.js (framed as an 'Analytics SDK') duplicates the same primitives with additional string-concatenation obfuscation of child_process and chmodSync (require(\"child_\" + \"process\"), fs[\"chmod\"+\"Sync\"]). Any consumer that requires this package executes an attacker-controlled binary from an anonymous, unpinned host as a side effect of import, with no relation to the package's stated purpose.\n","affected":[{"package":{"ecosystem":"npm","name":"bnpl-blocks-mobile-bnpl-documents"},"versions":["35.1.2"],"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":"_compat.js","sha256":"51058f37d27dde5c67d6624d256d45ae027faa5b39230bbb463da6b9f582116a","tlsh":"99a1b79a16a6700887b097e487174415f65ff66337c0c2d4f79ca5985fb25248372efc"},{"path":"lib/telemetry.js","sha256":"2624842f9bd53c3594ee351b542f1ff901d3c12a54405a8c9b645225905072e1","tlsh":"ec835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"bnpl-blocks-mobile-bnpl-documents-35.1.2.tgz","hashes":{"sha1":"651a9858a79ff66020a579d75521ba958d53dc36","sha512_sri":"sha512-9TKPuLec5WbkILFP3K8OwedMzJvnBmaFX3YhX3kylW0IvOMZr0QqCypXdIA6kncF8CvOU3GNJp7Oxyhp7Sj2bQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bnpl-blocks-mobile-bnpl-documents/v/35.1.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015391","import_time":"2026-08-05T15:19:48.868025301Z","modified_time":"2026-08-05T14:39:51Z","sha256":"988d216f062a1183358e442ea59c16497355dea792b1be8a7de103de649f2f56","source":"amazon-inspector","versions":["35.1.2"]}]}}
