Destination hostnames are reconstructed at runtime from split-string arrays joined together, evading static string matching. The fetched binary is written to /tmp/.cache_<hex> on Unix or %TEMP%\\dotnet_diag_<hex>.exe on Windows (names disguised to resemble system caches or.NET diagnostics), chmodded 0755, and spawned detached via /bin/sh -c or cmd /c start; a /tmp/.analytics_state marker suppresses re-execution. lib/telemetry.js carries a second copy of the same spawn/chmod/base64-buffer pattern. The dropper is framed as 'analytics' telemetry with a DISABLE_TELEMETRY-style opt-out as cover. No pinning, no hash verification, and the delivery hosts do not match the declared publisher of a 'Build and deployment tools' widget package.\n","affected":[{"package":{"ecosystem":"npm","name":"sme-rko-finance-front-operations-widget-impl"},"versions":["35.8.1"],"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":"setup.js","sha256":"d8a1f176a0a41dd4a8f0addb01cbd7d0455e6f61dc14cd78f33ff55153157748","tlsh":"87a1c7151afa30184792e1d8852b981671def69333c4d998fb8c66984f9627483f39fc"}],"package_integrity":[{"filename":"sme-rko-finance-front-operations-widget-impl-35.8.1.tgz","hashes":{"sha1":"2f505df543a108788b1a3ee902a76b0b9f4f58b4","sha512_sri":"sha512-etH38F4LMiBHhhfWzlf4ttTkA1Vs7bfJABmQmLaA7cPPKWaQOpVxUe3h4pDqNlZ4Hl5b8L7hnlFhHQvsHGMhWA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/sme-rko-finance-front-operations-widget-impl/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017155","import_time":"2026-08-08T00:53:07.41294289Z","modified_time":"2026-08-08T00:45:49Z","sha256":"f1cadf7bdbe8322e1878572d42f769a267d9a2af7a61c0da00f02c1436799824","source":"amazon-inspector","versions":["35.8.1"]}]}}
