Do not edit below this line.=-_\n\n## Source: amazon-inspector (f1cadf7bdbe8322e1878572d42f769a267d9a2af7a61c0da00f02c1436799824)\nindex.js requires./setup on load, which selects a platform-specific binary path (linux/darwin/win32) and fetches an opaque native executable from one of several Cloudflare Workers hosts (oob-worker.cf100-*.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT base64 fallback via sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. Destination hostnames are reconstructed at runtime from split-string arrays joined together, evading static string matching. The fetched binary is written to /tmp/.cache_\u003chex\u003e on Unix or %TEMP%\\dotnet_diag_\u003chex\u003e.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","modified":"2026-08-08T01:04:48.774841510Z","published":"2026-08-08T00:45:49Z","database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","versions":["35.8.1"],"id":"IN-MAL-2026-017155","import_time":"2026-08-08T00:53:07.41294289Z","modified_time":"2026-08-08T00:45:49Z","sha256":"f1cadf7bdbe8322e1878572d42f769a267d9a2af7a61c0da00f02c1436799824"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/sme-rko-finance-front-operations-widget-impl/v/35.8.1"}],"affected":[{"package":{"name":"sme-rko-finance-front-operations-widget-impl","ecosystem":"npm","purl":"pkg:npm/sme-rko-finance-front-operations-widget-impl"},"versions":["35.8.1"],"database_specific":{"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"evidence_files":[{"tlsh":"87a1c7151afa30184792e1d8852b981671def69333c4d998fb8c66984f9627483f39fc","path":"setup.js","sha256":"d8a1f176a0a41dd4a8f0addb01cbd7d0455e6f61dc14cd78f33ff55153157748"}],"package_integrity":[{"filename":"sme-rko-finance-front-operations-widget-impl-35.8.1.tgz","hashes":{"sha1":"2f505df543a108788b1a3ee902a76b0b9f4f58b4","sha512_sri":"sha512-etH38F4LMiBHhhfWzlf4ttTkA1Vs7bfJABmQmLaA7cPPKWaQOpVxUe3h4pDqNlZ4Hl5b8L7hnlFhHQvsHGMhWA=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/sme-rko-finance-front-operations-widget-impl/MAL-2026-13651.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
