Destination hostnames and fallback resolver domains are hidden by joining split string fragments at runtime to evade static inspection. The downloaded binary is written to /var/tmp or %TEMP% under a disguised name (`.cache_<hex>` or `dotnet_diag_<hex>.exe`), chmodded to 0755, and spawned detached via /bin/sh -c or cmd.exe. Naming choices (`analytics_state`, `DISABLE_TELEMETRY`, `dotnet_diag_*.exe`) and a cooldown stamp present the behavior as benign telemetry while the code fetches and executes attacker-controlled native code on every consumer that imports the package. The DNS-TXT fallback provides a covert delivery channel that bypasses HTTP egress controls.\n","affected":[{"package":{"ecosystem":"npm","name":"sme-rko-finance-front-operations-widget-domain"},"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":"_compat.js","sha256":"3a305ad6834b55b3781391eead0e0f8a3f5ff53a325795d0d10d2c4103387154","tlsh":"9fa1845a16fb30180792e1d5851f6416719af5933684e8d4fb4c66984fe723883f3afc"}],"package_integrity":[{"filename":"sme-rko-finance-front-operations-widget-domain-35.8.1.tgz","hashes":{"sha1":"80883baaabb2b17ee3689e201986aa48c2377325","sha512_sri":"sha512-ClxXRTk/BGnO4b3N45H54AZiwYRgvOsTgLVjF8pvg00bEPcp9Hcoxf4Haa8qrECfG9TrIGSPFVlUKcJ8SAQ/nA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/sme-rko-finance-front-operations-widget-domain/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017159","import_time":"2026-08-08T00:53:07.670794841Z","modified_time":"2026-08-08T00:46:19Z","sha256":"13823f2899a1bfed6b46575763e7ee2629fa4d9388130713a88125b1f38d6dae","source":"amazon-inspector","versions":["35.8.1"]}]}}
